Description

PRIORITY APPLICATION

This application claims the benefit of priority under 35 U.S.C. §119 of U.S. Provisional Application No. 62/329,592, filed on Apr. 29, 2016, the content of which is relied upon and incorporated herein by reference in its entirety.

BACKGROUND

The disclosure relates to implementing distributed antenna systems (DAS), and more particularly to implementing a live DAS configuration from a virtual DAS design using an original equipment manufacturer (OEM) specific software system in a DAS.
Wireless customers are increasingly demanding wireless communications services, such as cellular communications services and Wi-Fi services. Thus, small cells, and more recently Wi-Fi services, are being deployed indoors. At the same time, some wireless customers use their wireless communication devices in areas that are poorly serviced by conventional cellular networks, such as inside certain buildings or areas where there is little cellular coverage. One response to the intersection of these two concerns has been the use of distributed antenna systems (DASs). A DAS usually includes a head-end unit (HEU) connected to remote equipment (e.g., remote access units (RAU), remote hub units (RHU), etc.) thereby creating antenna coverage areas for establishing communications with wireless client devices located therein. In particular, the RAUs are configured to receive and transmit communications signals to client devices within the antenna range of the RAUs. DASs can be particularly useful when deployed inside buildings or other indoor environments where the wireless communication devices may not otherwise be able to effectively receive radio frequency (RF) signals from a source.
In this regard, FIG. 1 illustrates a wireless distributed communications system (WDCS) 100 that is configured to distribute communications services to remote coverage areas 102(1)-102(N), where ‘N’ is the number of remote coverage areas. The WDCS 100 in FIG. 1 is provided in the form of a DAS 104. The DAS 104 can be configured to support a variety of communications services that can include cellular communications services, wireless communications services, such as RF identification (RFID) tracking, Wireless Fidelity (Wi-Fi), local area network (LAN), and wireless LAN (WLAN), wireless solutions (Bluetooth, Wi-Fi Global Positioning System (GPS) signal-based, and others) for location-based services, and combinations thereof, as examples. The remote coverage areas 102(1)-102(N) are created by and centered on RAUs 106(1)-106(N) connected to a centralized equipment 108 (e.g., a head-end controller, a central unit, or a head-end unit). The centralized equipment 108 may be communicatively coupled to a source transceiver 110, such as for example, a base transceiver station (BTS) or a baseband unit (BBU). In this regard, the centralized equipment 108 receives downlink communications signals 112D from the source transceiver 110 to be distributed to the RAUs 106(1)-106(N). The downlink communications signals 112D can include data communications signals and/or communication signaling signals, as examples. The centralized equipment 108 is configured with filtering circuits and/or other signal processing circuits that are configured to support a specific number of communications services in a particular frequency bandwidth (i.e., frequency communications bands). The downlink communications signals 112D are communicated by the centralized equipment 108 over a communications link 114 (e.g., one or more communication links) over their frequency to the RAUs 106(1)-106(N).
With continuing reference to FIG. 1, the RAUs 106(1)-106(N) are configured to receive the downlink communications signals 112D from the centralized equipment 108 over a communications link 114. The downlink communications signals 112D are configured to be distributed to the respective remote coverage areas 102(1)-102(N) of the RAUs 106(1)-106(N). The RAUs 106(1)-106(N) are also configured with filters and other signal processing circuits that are configured to support all or a subset of the specific communications services (i.e., frequency communications bands) supported by the centralized equipment 108. In a non-limiting example, the communications link 114 may be a wired communications link, a wireless communications link, or an optical fiber-based communications link. Each of the RAUs 106(1)-106(N) may include an RF transmitter/receiver (not shown) and a respective antenna 116(1)-116(N) operably connected to the RF transmitter/receiver to wirelessly distribute the communications services to user equipment (UE) 118 within the respective remote coverage areas 102(1)-102(N). The RAUs 106(1)-106(N) are also configured to receive uplink communications signals 112U from the UE 118 in the respective remote coverage areas 102(1)-102(N) to be distributed to the source transceiver 110.
Designers of DAS systems use third party software to create RF designs that provide recommended configurations for placement and settings of remote equipment (e.g., RAUs or RHUs). These RF designs are used by installers to perform initial installations of equipment for a DAS. This remote equipment include remote units, including remote access units that contains electronics (e.g., fiber transceivers, filters, power amplifiers, built in antenna(s) or port(s)) to connect the remote equipment to external antenna(s) that propagate RF signals. Among other things, the RF designs provide predicted output power per Wireless Operator (e.g., Wireless Carrier), and predicted individual channel powers for various Wireless Operator protocols or technologies (e.g., LTE, UMTS, CDMA, EVDo, GSM, etc.) at each remote device.
Once the RF design is complete, the DAS system installer and/or commissioner (e.g., who commission and/or optimize the DAS system) attempts to construct and/or commission the DAS system to closely match the RF design. The installer connects the remote equipment at or near the locations indicated in the design. The commissioner can calibrate settings for the DAS system components (e.g., remote equipment) per the manufacturer specific instructions. Placement and settings can be varied from the RF design according to the environment and experience of the commissioner. The commissioner integrates (e.g., connects) the equipment to distribute live signals (provided from wireless operator signal source equipment (and/or other equipment)) into DAS head-end components (e.g., the Radio Interface Module(s) (RIM), power conditioner(s), etc.). The commissioner also optimizes output power of the remote equipment (e.g., RAUs or RHUs) per the wireless operator technology and/or protocol.
The third party RF design software may allow designers to complete system designs that violate DAS manufacturer specific software and hardware configuration requirements. Such RF design errors can lead to unplanned delays and/or unplanned systems costs from an inability to implement the system as originally designed. For example, the installer and/or commissioner may be required to obtain additional components to complete DAS installation and/or commissioning. Further, the layout and location of the HEU and other components within the equipment racks and modules within the cassis are left to the discretion of the installer. The installer may mount and install system components in a way that is different than the intended design (whether or not properly documented by the designer). As a result, it may be required to re-rack equipment or reposition modules within the cassis, which could invalidate commissioning of the system. Further, the DAS system design may not include information regarding how to configure DAS manufacturer specific system components through DAS manufacturer specific software interfaces (e.g., web-accessible graphical user interface (GUI), local GUI, etc.). Thus, the commissioner may configure the DAS equipment settings in a suboptimal manner (e.g., signal(s) does not reach the intended remote location(s), RF propagated at unintended power levels, etc.).

SUMMARY

Embodiments of the disclosure are directed to implementing a live distributed antenna system (DAS) configuration from a virtual DAS design using an original equipment manufacturer (OEM) specific software system in a real DAS. The OEM specific software can be resident software in the DAS or accessible by the DAS. In exemplary aspects disclosed herein, the OEM specific software system enables a designer to create, save, import, modify and/or preconfigure a virtual DAS in a virtual DAS configuration file(s) using OEM specific software tools resident in the real DAS. The OEM specific software tools could include functionality such as the ability to incorporate and enforce data, information, specifications, and/or limitations of the real DAS (e.g., OEM design constraints) for example, to facilitate design and optimization of the virtual DAS for improved and optimized performance of the real DAS. The configuration file(s) can then be subsequently implemented to modify and/or configure live equipment of a real DAS (e.g., to automatically calibrate the live equipment). Additionally, the configuration file(s) could guide a user through installation of the real DAS equipment to ensure proper installation thereof. The OEM specific software tools and local execution of the virtual DAS facilitates, improves, and optimizes DAS design and execution, and ensures that the real DAS substantially matches the DAS design. Thus, errors associated with design, installation, commissioning, and/or optimization may be reduced, and performance improved and optimized.

DETAILED DESCRIPTION

Reference will now be made in detail to the present preferred embodiments, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. One embodiment of an original equipment manufacturer (OEM) specific software system is shown in FIG. 2, and is designated generally throughout by the reference numeral 200.
Embodiments of the disclosure are directed to implementing a live distributed antenna system (DAS) configuration from a virtual DAS design using an OEM specific software system in a real DAS. The OEM specific software can be resident software in the DAS or accessible by the DAS. In exemplary aspects disclosed herein, the OEM specific software system enables a designer to create, save, import, modify and/or preconfigure a virtual DAS in a virtual DAS configuration file(s) using OEM specific software tools resident in the real DAS. The OEM specific software tools could include functionality such as the ability to incorporate and enforce data, information, specifications, and/or limitations of the real DAS (e.g., OEM design constraints) for example, to facilitate design and optimization of the virtual DAS for improved and optimized performance of the real DAS. The configuration file(s) can then be subsequently implemented to modify and/or configure live equipment of a real DAS (e.g., to automatically calibrate the live equipment). Additionally, the configuration file(s) could guide a user through installation of the real DAS equipment to ensure proper installation thereof. The OEM specific software tools and local execution of the virtual DAS facilitates, improves, and optimizes DAS design and execution, and ensures that the real DAS substantially matches the DAS design. Thus, errors associated with design, installation, commissioning, and/or optimization may be reduced, and performance improved and optimized.
In aspects disclosed herein, the OEM specific software system (e.g., DAS manufacturer OEM specific software system) enables a DAS designer to create a virtual DAS (e.g., which could be referred to as a “Profile”) and/or upload or import an existing real DAS to create a virtual DAS. The DAS designer can then modify the virtual DAS (e.g., adding or removing buildings or DAS components, reconfiguring user definable settings for the virtual DAS or DAS components, etc.). The user definable settings of the virtual DAS include equipment layout and physical connectivity between (1) system components and/or (2) modules within rooms, racks, or chassis. The virtual DAS can include components being physically located in multiple buildings or structures as well as outdoor locations. The OEM specific software system may further enable pre-configuration of some or all user definable settings in the virtual DAS in advance of the virtual DAS being activated on a real DAS (e.g., live DAS, active DAS, etc.), or prior to the real DAS being otherwise deployed.
The virtual design profile within the DAS OEM specific software can be created at one location or on one system, and can be loaded onto another system at the same or different location either locally at a DAS system site(s) or through internet connections. A bill of materials of system components may be generated automatically or manually for the virtual components within the virtual DAS, or from modifications to the virtual DAS (e.g., of an existing system), such as if a virtual component moves, is added, or otherwise changes. This can simplify procurement of equipment (e.g., signal distribution equipment, real equipment, etc.) for the real DAS.
The OEM specific software system may further enable a user (e.g., designer) to create virtual placeholders for equipment (e.g., Radio Interface Module(s) (RIMs), Optical Interface Module(s) (OIMs), Remote Access Units, which may be Remote Antenna Units (RAUs) for example or other remote equipment, fiber connectivity module(s) (FCMs), etc.) to reserve and preconfigure settings for future planned equipment to be added later to the real DAS. For example, if only one wireless operator joins the system after the initial commissioning, but another wireless operator is expected to join the system at a later date, having virtual placeholders for equipment (e.g., gear) would allow additional equipment to be seamlessly added to the real DAS at a later date without the need for a change to most, if not all, of the system configuration settings.
The OEM specific software system enables a user to adjust or preset any of the user definable virtual settings in a virtual placeholder component (e.g., like equipment). The virtual settings for equipment (e.g., RAU, FCM link, other remote equipment, etc.) would be automatically uploaded (e.g., applied, activated, etc.) to equipment once connected or otherwise put in communication with the OEM specific software system (e.g., positioned inside of a slot(s) in a chassis, connected by optical fiber(s), upon manual activation of the component, etc.). Virtual placeholders for future equipment could be configured to not generate or mask associated system monitoring alarms, such as those for missing active equipment. The OEM specific software system may also automatically calculate and/or modify (e.g., compensate or adjust) attenuator or gain settings within placeholder and existing components to automatically compensate for anticipated gains or losses in equipment for reasons such as amplifier sharing in advance of placeholder components being replaced by equipment, or if placeholder or existing components are removed from the system.
Once completed, the virtual DAS can be uploaded onto and activated into the memory of the real DAS (e.g., real DAS manufacturer specific system controller hardware, new or existing equipment, etc.), whether on a new or existing system. In certain embodiments, the virtual DAS (e.g., profile, virtual design profile, etc.) has no impact on active or live system settings until the user “activates” or uploads the virtual settings into the live or active system hardware. The OEM specific system user interface or graphical user interface (GUI) could guide the installer(s) through the installation process of the DAS components so that the real DAS (e.g., active DAS, live DAS, etc.) matches that of the virtual DAS, such as by guiding an installer through connection of equipment (e.g., DAS components, DAS modules, etc.), their physical location(s) (e.g., placement of components within an equipment rack, placement of equipment modules within a chassis or chassis slot, etc.), etc. The OEM specific software system could also guide an installer as to RF, optical, and communication cable connections between multiple chassis and head-end to remote location or multi-building connections, where to physically place remote equipment on a map or building floor plan diagram, etc.
In particular, the OEM specific software system could provide feedback (e.g., confirmation messages, error messages, successful installation messages, unsuccessful installation messages, etc.) if the installer correctly or incorrectly installs or connects equipment (e.g., whether the equipment or module(s) are in the proper physical location, chassis, or chassis slot). Monitoring of installation by the OEM specific software system could be from electrical or optical connections between components, from location based service detection (e.g., Bluetooth transceivers, RFID, GPS), etc. Such feedback could include visual indicators such as text, symbols, color coded indicators, or audible indicators. The OEM specific software system could also provide guidance on installation of individual components, or multiple components simultaneously. For example, the installation instruction or guidance from the user interface could show a diagram of all modules that are to be installed inside of a chassis simultaneously. As the user slides modules individually inside of the chassis, the user could receive feedback that the installation of those modules was successful or unsuccessful.
The commissioning process (e.g., integration and/or optimization of live signals or protocols) for the real DAS could be simplified and completed more efficiently. For example, user definable downlink (DL) maximum expected input power settings or attenuator settings at the point of interface equipment could be commissioned through the OEM specific software system. DAS manufacturer specific settings can include single or multiple RF path configurations, power amplifier settings, attenuator settings, and expected maximum and idle RF input power settings at point of interface modules, such as RIM(s) or conditioners that connect with incoming signals provided by Wireless Operator equipment (e.g., Base Station(s), Small Cell(s), BBU(s), Remote Radio Head(s) (RRH) or Metro Cell(s), etc.). The RF path configuration settings can open and close switches within the electronics at the head-end, directing digital, RF, or optical signals within head-end components to remote equipment.
In this regard, FIG. 2 is a schematic diagram of an exemplary embodiment of an optical fiber-based distributed antenna system (DAS) 200 (hereinafter “real DAS 200”) with equipment 202 (e.g., signal distribution equipment, real equipment, etc.) that includes exemplary head-end equipment 204 and a remote access unit (RAU) 206. A real DAS 200 and equipment 202 mean that they are tangible (as opposed to a virtual DAS and virtual equipment which are non-tangible). Note that the real DAS 200 can include multiple RAUs although only one RAU 206 is shown in FIG. 2. In this embodiment, the real DAS 200 that is configured to create one or more antenna coverage areas for establishing communications with wireless client devices located in the RF range of the antenna coverage areas. The real DAS 200 provides RF communications services (e.g., cellular services). In this embodiment, the real DAS 200 includes the head-end equipment 204 in the form of a head-end unit (HEU) 208, one or more of the RAUs 206, and a communications medium in the form of an optical fiber 210 that communicatively couples the HEU 208 to the RAU 206 in this example. In one example, the HEU 208 is provided as a chassis with electronic equipment installed therein. The HEU 208 is configured to receive communications over downlink network link 214 (e.g., communications medium, connection, wire, etc.) from a source or sources, such as a network 216 or carrier as examples, and provide such communications to the RAU 206. The HEU 208 is also configured to return uplink electrical RF communications signals 218U received from the RAU 206, via network link 214, back to the source or sources. In this regard, in this embodiment, the optical fiber 210 includes at least one downlink optical fiber 212D to carry signals communicated from the HEU 208 to the RAU 206, and at least one uplink optical fiber 212U to carry signals communicated from the RAU 206 back to the HEU 208. One downlink optical fiber 212D and one uplink optical fiber 212U could be provided to support multiple channels each using wavelength-division multiplexing (WDM), as discussed in U.S. patent application Ser. No. 12/892,424 filed Sep. 28, 2010 entitled “Providing Digital Data Services in Optical Fiber-Based Distributed Radio Frequency (RF) Communications Systems, and Related Components and Methods,” incorporated herein by reference in its entirety. Other options for WDM and frequency-division multiplexing (FDM) are also disclosed in U.S. patent application Ser. No. 12/892,424, any of which can be employed in any of the embodiments disclosed herein.
The real DAS 200 (e.g., optical fiber-based) has an antenna coverage area 220 that can be substantially centered about the RAU 206. The antenna coverage area 220 of the RAU 206 forms an RF coverage area 222. The HEU 208 is adapted to perform or to facilitate any one of a number of wireless applications, including but not limited to Radio-over-Fiber (RoF), radio frequency identification (RFID), wireless local-area network (WLAN) communication, public safety, cellular, telemetry, and other mobile or fixed services. Shown within the antenna coverage area 220 is a client device 226 in the form of a mobile device as an example, which may be a cellular telephone as an example. The client device 226 can be any device that is capable of receiving RF communication signals. The client device 226 includes an antenna 228 (e.g., a wireless card) adapted to receive and/or send electromagnetic RF communications signals.
With continuing reference to FIG. 2, to communicate the RF communications signals 218D over the downlink optical fiber 212D to the RAU 206, to in turn be communicated to the client device 226 in the antenna coverage area 220 formed by the RAU 206, the HEU 208 includes an electrical-to-optical (E/O) converter 230. The E/O converter 230 converts the downlink electrical RF communications signals 218D to downlink optical RF communications signals 224D to be communicated over the downlink optical fiber 212D. The RAU 206 includes an optical-to-electrical (O/E) converter 232 to convert received downlink optical RF communications signals 224D back to electrical RF communications signals to be communicated wirelessly through an antenna 234 of the RAU 206 to client devices 226 located in the antenna coverage area 220.
Similarly, the antenna 234 is also configured to receive wireless RF communications from the client devices 226 in the antenna coverage area 220. In this regard, the antenna 234 receives wireless RF communications from the client devices 226 and communicates electrical RF communications signals representing the wireless RF communications to an E/O converter 236 in the RAU 206. The E/O converter 236 converts the electrical RF communications signals into uplink optical RF communications signals 224U to be communicated over the uplink optical fiber 212U. An 0/E converter 240 provided in the HEU 208 converts the uplink optical RF communications signals 224U into uplink electrical RF communications signals, which can then be communicated as uplink electrical RF communications signals 218U back to a network or other source. The HEU 208 in this embodiment is not able to distinguish the location of the client devices 226. The client device 226 could be in the range of any antenna coverage area 220 formed by an RAU 206.
With continuing reference to FIG. 2, the HEU 208 includes a service unit 242, which may be a remote interface module (RIM), that provides electrical RF service signals by passing (or conditioning and then passing) such signals from one or more outside networks 216 via a network link 214. In a particular exemplary embodiment, this includes providing WLAN signal distribution as specified in the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, i.e., in the frequency range from 2.4 to 2.5 GigaHertz (GHz) and from 5.0 to 6.0 GHz. Any other electrical RF communications signal frequencies are possible. In another exemplary embodiment, the service unit 242 provides electrical RF service signals by generating the signals directly. In another exemplary embodiment, the service unit 242 coordinates the delivery of the electrical RF service signals between client devices 226 within the antenna coverage area 220.
With continuing reference to FIG. 2, the service unit 242 is electrically coupled to the E/O converter 232 that receives the downlink electrical RF communications signals 218D from the service unit 242 and converts them to corresponding downlink optical RF communications signals 224D. In an exemplary embodiment, the E/O converter 232 includes a laser suitable for delivering sufficient dynamic range for RoF applications, and optionally includes a laser driver/amplifier electrically coupled to the laser. Examples of suitable lasers for the E/O converter 232 include, but are not limited to, laser diodes, distributed feedback (DFB) lasers, Fabry-Perot (FP) lasers, and vertical cavity surface emitting lasers (VCSELs).
With continuing reference to FIG. 2, the HEU 208 also includes the O/E converter 240, which is electrically coupled to the service unit 242. The O/E converter 240 receives the uplink optical RF communications signals 224U and converts them to corresponding uplink electrical RF communications signals 218U. In an exemplary embodiment, the O/E converter 240 is a photodetector, or a photodetector electrically coupled to a linear amplifier. The E/O converter 232 and the O/E converter 240 are provided in an optical interface module (OIM) 238 in this example.
In accordance with an exemplary embodiment, the service unit 242 in the HEU 208 can include an RF communications signal conditioner unit 240 for conditioning the downlink electrical RF communications signals 218D and the uplink electrical RF communications signals 218U, respectively. The service unit 242 can include a digital signal processing unit (“digital signal processor”) 246 for providing to the RF communications signal conditioner unit 244 an electrical signal that is modulated onto an RF carrier to generate a desired downlink electrical RF communications signal 218D. The digital signal processor 246 is also configured to process a demodulation signal provided by the demodulation of the uplink electrical RF communications signal 218U by the RF communications signal conditioner unit 244. The service unit 242 in the HEU 208 can also include an optional central processing unit (CPU) 248 for processing data and otherwise performing logic and computing operations, and a memory unit 250 for storing data, such as data to be transmitted over a WLAN or other network for example. The HEU 208 also includes the OEM specific software system 252, which could be stored in the memory unit 250 and accessed and processed by the CPU 248.
With continuing reference to FIG. 2, the RAU 206 also includes a converter pair 256 comprising the O/E converter 232 and the E/O converter 236. The O/E converter 232 converts the received downlink optical RF communications signals 224D from the HEU 208 back into downlink electrical RF communications signals 258D. The E/O converter 236 converts uplink electrical RF communications signals 258U received from the client device 226 into the uplink optical RF communications signals 224U to be communicated to the HEU 208. The O/E converter 232 and the E/O converter 236 are electrically coupled to the antenna 234 via an RF signal-directing element 260, such as a circulator for example. The RF signal-directing element 260 serves to direct the downlink electrical RF communications signals 258D and the uplink electrical RF communications signals 258U, as discussed below. In accordance with an exemplary embodiment, the antenna 234 can include one or more patch antennas, such as disclosed in U.S. patent application Ser. No. 11/504,999, filed Aug. 16, 2006 entitled “Radio-over-Fiber Transponder With A Dual-Band Patch Antenna System,” now issued U.S. Pat. No. 7,627,250, and U.S. patent application Ser. No. 11/451,553, filed Jun. 12, 2006 entitled “Centralized Optical-Fiber-Based Wireless Picocellular Systems and Methods,” both of which are incorporated herein by reference in their entireties.
With continuing reference to FIG. 2, the real DAS 200 also includes a power supply 262 that generates an electrical power signal 264. The power supply 262 is electrically coupled to the HEU 208 for powering the power-consuming elements therein. In an exemplary embodiment, an electrical power line 266 runs through the HEU 208 and over to the RAU 206 to power the O/E converter 232 and the E/O converter 236 in the converter pair 256, the optional RF signal-directing element 260 (unless the RF signal-directing element 260 is a passive device such as a circulator for example), and any other power-consuming elements provided. In an exemplary embodiment, the electrical power line 266 includes two wires 268 and 270 that carry a single voltage and that are electrically coupled to a DC power converter 272 at the RAU 206. The DC power converter 272 is electrically coupled to the O/E converter 232 and the E/O converter 236 in the converter pair 256, and changes the voltage or levels of the electrical power signal 264 to the power level(s) required by the power-consuming components in the RAU 206. In an exemplary embodiment, the DC power converter 272 is either a DC/DC power converter or an AC/DC power converter, depending on the type of electrical power signal 264 carried by the electrical power line 266. In another exemplary embodiment, the electrical power line 266 (dashed line) runs directly from the power supply 262 to the RAU 206 rather than from or through the HEU 208. In another exemplary embodiment, the electrical power line 266 includes more than two wires and carries multiple voltages.
FIG. 3 provides additional information and equipment of the real DAS 200 discussed above with respect to FIG. 2. More specifically, FIG. 3 is a schematic diagram of an exemplary real DAS 200 that includes a head-end control module (HCM) 310 configured to provide head-end equipment for distributing and receiving RF communications signals to and from RAUs 206. The HCM 310 enables centralized, single-source local and remote management of DAS equipment (e.g., ACMs). This particular embodiment of the real DAS 200 comprises a main site head-end 300, a remote site A 302, a remote site B 304, and remote subsite B 306 (e.g., at remote site B or proximate thereto). The main site head-end 300 comprises a controller web session 308, used to access the OEM specific software system 252 via the HCM 310 over the network 216 (e.g., local area network (LAN)). In certain embodiments, the HCM 310 is a part of the main HEU 208. The HCM 310 is connected to a first HEU 312 (with auxiliary control modules (ACMs)), a first optical interface unit (OIU) 314 (with ACM), a second HEU 316 (with ACM), and a second OIU 318 (with ACM) via management (MGMT) cables. The main HEU 208 is connected to a first HEU 312 (with ACM), a first OIU 314 (with ACM), a second HEU 316 (with ACM), and a second OIU 318 (with ACM) via coaxial cables. Connection of the HCM with four ACMs enables centralized management for all connected head-end and remote-end site elements.
The first OIU 314 and second OIU 218 are connected via a fiber optic cable(s) to a first ICU 320 at remote site A 302. The ICU 320 is configured to provide power for powering the RAUs 206. The ICU 320 may be configured to provide the power in a composite cable along with the optical fibers carry signals from the HEU 208 to the RAUs 206. The first ICU 320 is connected to one or more RAUs 206 that transmit downlink electrical RF communications signals 258D (each RAU 206 may include RF expansion (remote expansion unit (RxU))). The second OIU 218 is also connected to an integrated head-end unit (IHU) 322 (with ACM) at remote site B 304 via an FMM-to-FRM fiber optic link. The IHU 322 (with ACM) is connected to an ICU 324 at remote subsite B 306 by a fiber optic cable(s). The ICU 324 is connected via a fiber optic cable(s) to one or more RAUs 206 that transmit downlink electrical RF communications signals 258D (each RAU 206 may include RF expansion (RxU)). The ICU 324 could also be connected via a fiber optic cable to a mid-power remote unit (MRU) 326 which then transmits downlink electrical RF communications signals 258D.
FIG. 4 is a schematic diagram of an exemplary RF path allocation between radio interface modules (RIMs) 406-418 of the HEU 208 and RAUs 206 in the real DAS of FIG. 3. Multiple RIM modules can be assorted with a single optical interface module (OIM) in each service group, and one RIM module can be associated with a number of OIMs in a service group. For example, in one embodiment, the RF paths for up to three service groups (e.g., service specific RIMs and/or OIMs) are configured. In this example, as shown, a head-end 300 includes a head-end unit (HEU) 208 and an OIU 420. The HEU 208 comprises a first service group 400, which includes the RIM #1 module 406, which is configured to transmit supported Service A to OIM #4 module 422 of OIU 420. The OIM #4 module 422 then transmits the supported Service A to RAUs 206A at remote end 428 which then transmit Service A 258A to one or more client devices 226 (not shown). The HEU 208 comprises a second service group 402, which includes RIM #1 module 408 and RIM #2 module 410, which are configured to transmit corresponding Services A,B to OIM #5 module 424 of OIU 420. The OIM #5 module 424 then transmits the supported Services A,B to RAUs 206B at remote end 428 which then transmit Services A,B 258B to one or more client devices 226 (not shown). The HEU 208 comprises a third service group 404, which includes RIM #1 module 412, RIM #2 module 414, RIM #3 module 416, and RIM #4 module 418, which are configured to transmit corresponding services A, B, C, D to OIM #6 module 426 of OIU 420. The OIM #6 module 426 then transmits the supported Services A, B, C, D to RAUs 206C at remote end 428, which then transmit Services A, B, C, D 258C to one or more client devices 226 (not shown).
FIG. 5 is a schematic diagram of an exemplary RF path allocation between RIMs 406-418 of the HEU 208 and RAUs 206 at a remote site 504 using an FMM-to-FRM link in the real DAS of FIG. 3. More specifically, FIG. 5 illustrates an example of RF paths configured for multiple sites, where the service signals are extended to a remote location via an FMM-FRM link.
For example, in one embodiment, the RF paths for up to three service groups (e.g., service specific RIMs and/or OIMs) are configured. In this example, the service groups are configured both at the main head-end 300 (e.g., main head-end site) and at the remote location (e.g., site 1 504) so that the services from the RIMs at the main head-end 300 are extended to OIMs at the remote location and distributed by their connected RAU remotes.
In this example, as shown (similar to that of FIG. 4), a main head-end 300 includes an HEU 208 and an OIU 500, and site 1 504 includes an HEU 506 and an OIU 420. The HEU 208 comprises a first service group 400, which includes the RIM #1 module 406, which is configured to transmit supported Service A to FMM 502 of OIU 500 of the main head-end 300. The OIU FMM 502 then transmits the supported service A to a FRM 508 of the HEU 506 of site 1 504. The site 1 HEU FRM 508 then transmits service A to OIM #4 module 422 of OIU 420. The OIM #4 module 422 then transmits the supported Service A to RAUs 206A at site 1 504, which then transmit Service A 258A to one or more client devices 226 (not shown).
The HEU 208 comprises a second service group 402, which includes RIM #1 module 408 and RIM #2 module 410, which are configured to transmit corresponding Services A,B to FMM 502 of OIU 500 of the main head-end 300. The OIU FMM 502 then transmits the supported services A,B to a FRM 508 of the HEU 506 of site 1 504. The site 1 HEU FRM 508 then transmits service A to OIM #5 module 424 of OIU 420. The OIM #5 module 424 then transmits the supported Services A,B to RAUs 206B at site 1 504, which then transmit Services A,B 258B to one or more client devices 226 (not shown).
The main head-end HEU 208 comprises a third service group 404, which includes RIM #1 module 412, RIM #2 module 414, RIM #3 module 416, and RIM #4 module 418, which are configured to transmit corresponding services A, B, C, D to FMM 502 of OIU 500 of the main head-end 300. The OIU FMM 502 then transmits the supported services A,B to a FRM 508 of the HEU 506 of site 1 504. The site 1 HEU FRM 508 then transmits service A to OIM #6 module 426 of OIU 420. The OIM #6 module 426 then transmits the supported Services A, B, C, D to RAUs 206C at site 1 504, which then transmit Services A, B, C, D 258C to one or more client devices 226 (not shown).
FIG. 6 is a front view of an exemplary integrated head-end unit (IHU) 600 with an installed head-end control module (HCM) 602 that can be employed in the real DAS of FIG. 3 for distributing and receiving RF communications signals to and from RAUs 206. More specifically, the HCM module 602 is installed at a head-end element (e.g., HEU, IHU 600) at the main site and enables centralized management and control capabilities of the DAS system. Auxiliary control modules (ACM) are installed in the remaining system head-end units and are interconnected (e.g., directly or indirectly) to the HCM enabling single source management via the HCM. The HCM could be connected to one or more HEU, OIU, and/or IHU units, whether directly or indirectly. In large configurations, the ACMs can be cascaded to each other.
In certain embodiments, the HCM module 602 interface comprises a console port 604, one or more internal ports (e.g., first internal port 606A, second internal port 606B, third internal port 606C, fourth internal port 606D, etc.), a LAN port 608, and/or a local port 610. The console port (e.g., RJ45, serial port) could be used for local configurations. The internal ports 606A-606D (e.g., RJ45, 100 Mb Ethernet ports) are used for management of connected ACMs installed in OIU chassis, HEU chassis, and/or IHU chassis. The ACM module interface would have corresponding similar internal ports for connecting to the HCM module interface 602. The LAN port 608 (e.g., RJ45, 1 Gb Ethernet port) connects to corporate LAN for remote management. The local port 610 (e.g., RJ45, 1 Gb Ethernet port) could be used for local configuration and management.
The real DAS 200 discussed above can be configured using the OEM specific software system 252 also discussed above. More specifically, the OEM specific software system 252 in the real DAS 200 can be used to implement a live DAS configuration from a virtual DAS design. In this regard, FIG. 7 is a flowchart of an exemplary process 700 for implementing a live DAS configuration from a virtual DAS design using an OEM specific software system of the real DAS of FIGS. 2 and 3 according to one embodiment. More specifically, at step 702, the OEM specific software system 252 in the real DAS 200 electronically configures at least one virtual DAS setting for a virtual DAS. At step 704, the OEM specific software system 252 electronically enforces upon the at least one virtual DAS setting OEM design constraints of at least one real setting of equipment in the real DAS 200. Thus, the OEM specific software system 252 incorporates and enforces data, information, specifications, and/or limitations of the real DAS (e.g., OEM design constraints) for example, to facilitate design and optimization of the virtual DAS for improved and optimized performance of the real DAS. In step 706, the OEM specific software system 252 electronically generates at least one virtual DAS configuration file 254 comprising the at least one virtual DAS setting for the virtual DAS. In step 708, the OEM specific software system 252 electronically stores the at least one virtual DAS configuration file in memory at the real DAS 200. In step 710, the 252 electronically modifies the at least one real setting of the equipment in the real DAS 200 based on the at least one virtual DAS setting in the at least one virtual DAS configuration file. Accordingly, the OEM specific software system 252 and local execution of the virtual DAS facilitates, improves, and optimizes DAS design and execution, and ensures that the real DAS substantially matches the DAS design. In step 712, the OEM specific software system 252 electronically guides an installer through proper installation of the equipment of the real DAS 200. Proper installation means that the real DAS 200 has been installed consistent with the design of the virtual DAS in the configuration file and the real DAS 200 has established communication among the equipment. In step 714, the OEM specific software system 252 determines whether the real DAS 200 has been properly installed. If the real DAS 200 has not been properly installed, then in step 716, the OEM specific software system 252 electronically alerts the installer as to errors and/or electronically guides the installer through corrections. Then, the process 700 reverts back to step 714. If the real DAS 200 has been properly installed in step 714, then in step 718, the OEM specific software system 252 automatically self-calibrates the real DAS 200 to ensure design compliance with the virtual DAS and/or to optimize performance of the real DAS 200 and the process 700 ends. Guiding a user through installation of the real DAS ensures compliance with the virtual DAS design. Thus, process 700 reduces errors associated with design, installation, commissioning, and/or optimization for improved performance and optimization of the real DAS 200.
As discussed above, the virtual DAS is used to configure equipment of the real DAS 200. FIG. 8 is a flowchart illustrating an exemplary process 800 for configuring a new virtual DAS (profile) using the OEM specific software system 252 of the real DAS 200 of FIGS. 2 and 3 according to one embodiment. In step 802, the OEM specific software system 252 at a real DAS 200 electronically configures a new virtual DAS (profile). In step 804, the OEM specific software system 252 electronically configures a new site for the virtual DAS. In step 806, the OEM specific software system 252 electronically configures source and destination sites of the virtual DAS. In step 808, the OEM specific software system 252 determines whether the virtual DAS has been properly configured. If the virtual DAS has not been properly configured, then in step 810, the OEM specific software system 252 electronically alerts a user as to errors and/or electronically guides the user through corrections. Then the process 800 reverts back to step 808. If the virtual DAS has been properly configured in step 808, then in step 812, the OEM specific software system 252 electronically transmits a notification to a user that the virtual DAS design is compliant and no errors were found.
FIGS. 9-19 are exemplary pages of a user interface of the OEM specific software system 252 for configuring a new virtual DAS (profile, virtual design profile, etc.) (as similarly described in FIG. 8). More specifically, FIG. 9 is an exemplary HCM controller login GUI page 900 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 for further access to the OEM specific software system 252. The login page 900 could be accessed through the HCM local port 610 of the HCM module 602 of the IHU 600 (or HEU) (as described above in FIG. 6). In certain embodiments, the login page 900 can be accessed through a web browser of a computer connected to the IHU 600 (or HEU) through the HCM local port 610. The login page 900 comprises a user name field 902, a password field 904, and/or group field 906. Login credentials could be set to default values for first time users, and then changed after first time login. A user, system commissioner, or installer can log into the DAS manufacturer OEM specific software system and upload and activate the settings and equipment configurations in the virtual DAS that was created by the system designer within DAS OEM specific software. A virtual DAS in a virtual DAS configuration file in the OEM specific software system can be created, accessed, modified, uploaded, downloaded, or activated locally at a real DAS and/or remotely through the internet.
FIG. 10 is an exemplary profile management page 1000 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 illustrating profile management options for creating and/or editing a virtual DAS (profile). The profile management page 1000 may comprise a number of tabs, such as a management tab 1002, events tab 1004, configuration tab 1006, administration tab 1008, profiles tab 1010, location tab 1012, multilink tab 1014, and/or a help tab 1016. The management tab 1002 enables a user to view and configure network topologies, device alarms, and/or other management options. The events tab 1004 enables a user to view and configure events that occurred on the monitored devices. The configuration tab 1006 enables a user to configure and commission installed system devices and adjustment procedure. The administration tab 1008 provides a user with administration options, such as firmware upgrades, user management options, IP settings (e.g., required for receiving traps), etc. The profiles tab 1010 enables a user to create a virtual DAS (profile) offline and then activate it at a later time. Each virtual DAS includes virtual DAS equipment (e.g., a physical configuration on the installed units) and virtual DAS settings (e.g., commissioning parameters). When the virtual DAS is activated, the OEM specific software system could provide step-by-step instructions on how to configure the system. The location tab 1012 enables a user to import maps and icons to graphically display the geographical location and types of sites, as well as the floor plans and map power settings for the system elements. The multilink tab 1014 enables managing and accessing multiple setups in the same network from a single point of management (e.g., enables performing specific operations on a plurality of connected HCMs). The help tab 1016 provides access to online help files and other resources.
To configure a new profile (via a GUI) using the OEM specific software system, a user first selects the profiles tab 1010, which then displays profile options area 1018 and a profiles list 1028. A profile is a profile configuration of a virtual DAS created for, linked with, and/or derived from a real DAS. In other words, a profile is a virtual DAS. In particular, the profile may include virtual DAS equipment and settings pertaining to physical installation, connection requirements, and/or commissioning, etc. The profiles tab 1010 electronically provides a GUI for a user to manage, create, delete, copy, and/or export a profile. Upon completing the profile configuration of the virtual DAS, the virtual DAS can then be activated, and the OEM specific software system 252 may guide an installer with step-by-step instructions on how to setup the real DAS, and may apply the profile configuration on the real DAS. After the profile has been successfully activated, the system can be adjusted via the configuration tab 1006.
The profile options area 1018 electronically displays to the user several options for interactive selection, such as creating a new profile 1020, creating a new profile from baseline 1022, creating a new profile from third party platform 1024, and/or importing a profile 1026. Creating a new profile 1020 enables the user to create a completely new profile. Creating a new profile from baseline 1022 enables a user to create a new profile based on the configuration of the existing online system in use. In other words, creating a new profile from baseline 1022 enables a user to quickly create a profile which can be subsequently edited according to site requirements. Creating a new profile from third party platform 1024 enables a user to load an electronic third party platform design (e.g., third party platform file), which could include antenna locations and/or antenna deployment. More specifically, the third party platform design could include floor layouts and/or setup design, and could be used as is or as a baseline configuration (to be further modified). Importing a profile 1026 enables a user to import a profile previously created and exported using the OEM specific software system 252.
The profiles list 1028 lists any profiles accessible to the user (e.g., by previous creation, by access rights, etc.), and may also display related information. For example, as illustrated in profile management page 1000 of FIG. 10, Profile_1 1030 is listed in the profiles list 1028 and includes the status (e.g., OK) as of a particular date and time (e.g., 31/May/2016 05:16:35).
FIG. 11 is an exemplary profile management page 1100 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 illustrating profile options. More specifically, once a profile has been created, edited, and/or selected, the OEM specific software system 252 shifts to offline mode, and a profile status 1102 of the profile or the system is provided (e.g., Offline mode-Profile_1, “Operating in Offline Mode”, etc.). The profile status 1102 notifies the user as to whether the profile is offline (not live) or online (live). Additionally, or alternatively, a color coded background can be used to indicate that the user (e.g., designer) is working within a virtual DAS rather than on an active or live DAS.
The OEM specific software system 252 also provides a profile administration subtab 1104 and a design subtab 1106. Under the profile administration subtab 1104 is a profile options area 1108 providing a GUI for the user to save a profile 1110, exit without saving 1112, and/or import a third party platform file 1114 containing location maps used to graphically display the geographical location of the site (e.g., building) and the layout of each floor. The maps are utilized and displayed in the “Location” main menu screen, where remotes (e.g., RAU, MRU) can be assigned and placed on the maps, representing their actual physical location in the floor plan.

For example, in certain embodiments, the configuration phases comprise a site configuration phase 2102, an amplifier sharing phase 2104, an antenna configuration phase 2106, a run-time options phase 2108, a zone information phase 2110, an adjustment phase 2112, etc.
The configuration phase 2102 enables a user to configure site specific parameters. The amplifier sharing phase 2104 enables the user to allocate different percentages of amplification for same band RIMs. The antenna configuration phase 2106 enables a user to select the antenna source type (e.g., internal, external) for each of the installed modules (e.g., RAU/RAU5 units). The run-time options phase 2108 enables a user to expand and/or replace modules. The zone information phase 2110 enables a user to label each unit in the system to help classify and locate the different units (e.g., Building 1; Floor 1; Room 1). The adjustment phase 2112 enables a user to perform the adjustment procedure for uplink and downlink gains of the RIMs and OIMs, as well as to adjust the target output power of the services transmitted by the remote-end units.
In certain embodiments, the status indicator indicates to a user whether a particular phase is currently being configured (e.g., red as shown in the site configuration phase 2102), is completed (e.g., green as shown in the amplifier sharing phase 2104), or has not yet been performed (e.g., transparent as shown in the antenna configuration phase 2106, the run-time options phase 2108, the zone information phase 2110, and the adjustment phase 2112).
The site configuration page 2100 further includes a select service group drop down menu 2114 enabling a user to select a particular service group (as discussed in FIGS. 4 and 5).

FIG. 22 is an exemplary site configuration page 2200 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 illustrating a module owner subphase of the site configuration phase. More specifically, the site configuration page 2200 provides a module owner subphase 2202 (with a first module owner status indicator 2210A and/or a second first module owner status indicator 2212A), a MIMO setup subphase 2204 (with a first module owner status indicator 2210B and/or a second first module owner status indicator 2212B), an RF path subphase 2206 (with a first module owner status indicator 2210C and/or a second first module owner status indicator 2212C), and/or a max input subphase 2208 (with a first module owner status indicator 2210D and/or a second first module owner status indicator 2212D).
The site configuration page 2200 could also include a first HEU chassis 2214 (with one or more modules 2220A-2220D), a second HEU chassis 2216 (with one or more modules 2222A-2222D), and/or a third HEU chassis 2218 (with one or more modules 2224A-2224C). Further, the site configuration page provides a carrier selection drop down menu 2226 requesting a user to select from one of a plurality of carriers (e.g., all, carrier 1, carrier 2, carrier 3, carrier 4, etc.). This enables a user to assign service specific RIM modules to one or more groups (e.g., corresponding to operators). The module owner subphase displays all connected HEUs and/or IHUs in a device view area. Unconfigured and unassigned RIM modules appear gray. All modules could be assigned to all groups or to specific groups (where groups include operators, carriers, etc.). Blue checkmarks could be applied to modules to indicate which modules are configured.
FIG. 23 is an exemplary site configuration page 2300 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 illustrating a MIMO setup subphase of the site configuration phase. The MIMO setup subphase enables a user to configure the modules (e.g., RIM modules) for the MIMO paths.
As shown in FIG. 23, the site configuration page 2300 could include a first HEU chassis 2302 (with a plurality of modules 2306A-2306E) and a second HEU chassis 2304 (with a plurality of modules 2308A-2308E). Each of the modules could have one or more status indicators to indicate to a user the status of the modules. For example, each of the modules could include a first colored status indicator and/or a second status indicator. The first colored status indicator could include green (e.g., to indicate a selected module), gray (e.g., to indicate a not selected module), and/or transparent (e.g., to indicate a disabled or disconnected module). The second status indicator could be a checkmark (e.g., a blue checkmark) to indicate if a module has been assigned and configured.
A user can select a first module (e.g., RIM-M module 2306E) in the first chassis 2302, and a second module (e.g., RIM module 2308E) in the second chassis 2304, and then indicate whether the two modules should be disconnected (e.g., by clicking a UPAIR button 2310) or connected (e.g., by clicking a PAIR button 2312). In this way, for example, the user can connect pairs of RIM-M and RIM modules supporting the same band (e.g., AWS) which will then be extended to the corresponding remote unit (e.g., via the OIM). The OEM specific software system 252 can guide a user through connecting modules. For example, modules that are available for pairing can be identified to a user. When the RIM-M module 2306E in the first chassis 2302 is selected, the compatible RIM modules in the second chassis 2304 will appear gray (e.g., RIM module 2308E), and incompatible or unavailable modules will appear transparent (e.g., RIM modules 2308A-2308D).
FIG. 24 is an exemplary site configuration page 2400 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 illustrating RF path configuration setup subphase of the site configuration phase (as discussed in FIGS. 4 and 5). The OEM specific software system 252 enables configuration of user controlled service groups, where each service group could be transferred to a specified remote site. As shown, the site configuration page 2400 provides a service group drop down menu 2402, and service group identifiers 2406A, 2406B, 2406C, displaying to a user which service group has been selected. Further, a module legend 2404 is provided that indicates whether a module is selectable, selected, and/or disabled, as shown in the first HEU chassis 2408A (with a plurality of first chassis modules 2410A), a second HEU chassis 2408B (with a plurality of first chassis modules 2410B), a third HEU chassis 2408C (with a plurality of first chassis modules 2410C), a first OIU chassis 2412A (with a plurality of first chassis modules 2414A), a second OIU chassis 2412B (with a plurality of first chassis modules 2414B), and a third OIU chassis 2412C (with a plurality of first chassis modules 2414C).
This arrangement could be used where different combinations of services are distributed at various locations on the same floor of a building according to coverage requirements. The RF path configuration setup subphase determines the services distributed at the remote site. Note that each RIM can be configured for all service groups, and each RIM can be assigned to each OIM in a service group. The OEM specific software system 252 could be configured such that selecting a RIM-M module automatically selects the connected RIM module as well, and configures the RIM module for the same service group.
FIG. 25 is an exemplary site configuration page 2500 provided by the OEM specific software system 252 of the HEU 208 of the real DAS 200 of FIGS. 2 and 3 illustrating a max-input configuration setup subphase of the site configuration phase. The max-input configuration setup subphase is used to set the DL maximum expected power (e.g., −10 to 37 dBm) for each RIM and the UL gain. The configured max expected power determines the maximum UL gain range enabled for configuration. As shown, the site configuration page 2500 includes a first chassis 2502 with a plurality of first chassis modules 2504, and a second chassis 2506 with a plurality of second chassis modules 2508.
