As shown in fig. 1, the ad hoc network access device includes a plurality of ad hoc network access devices (APs) 11 and ad hoc network control devices (ACs) 12. Referring to fig. 2, the ad hoc network access device 11 may include a near-end microwave module 21 and a far-end microwave module 22. The near-end microwave module 21 includes a modem 211, a multiplexer 212, a controller 213, a power supply 214, a MESH ad hoc network module 215, and a first communication circuit 216. As shown in fig. 3, the remote microwave module 22 includes a fixed module 221, a connection module 222, a digital microwave rf module 223, and a second communication circuit 224, the fixed module 221 is connected to the digital microwave rf module 223 through the connection module 222, the communication circuit 224 is connected to the digital microwave rf module 223 in communication, the communication circuit 224 may be disposed on the digital microwave rf module 223 or on the fixed module 221, and the radio frequency module may include an up/down rf converter, a Power Amplifier (PA), a Low Noise Amplifier (LNA), a filter, a gain control, an rf signal processing, a duplexer or an antenna coupling unit, and so on. The near-end microwave assembly 21 and the far-end microwave assembly 22 can communicate with the first communication circuit 216 through the second communication circuit 224, and the second communication circuit 224 and the first communication circuit 216 can be a bluetooth module or a wifi module.

The MESH ad hoc network module 215 is configured to implement automatic access of each ad hoc network access device 11. The MESH ad hoc network module 215 may support one or more protocols. For example, dynamic source routing protocol (DSR), destination sequence distance vector routing protocol (DSDV), temporal in-order routing algorithm (TORA), Ad Hoc on-demand distance vector routing protocol (AODV), and the like.

The digital microwave rf module 223 may be a planar antenna, a horn antenna, a parabolic antenna, or a cassegrain antenna. The digital microwave radio frequency assembly 223 is generally comprised of a waveguide and a coaxial cable.

The modem 211 is a short for Modulator and Demodulator, and is called a modem in chinese, and is a component capable of implementing modulation and demodulation functions required for digital microwave communication.

A multiplexer 212, a multiplexer or mux, that can select and forward a signal from a plurality of analog or digital input signals, and output different selected signals onto the same output line. Multiplexing may follow one of the following principles, for example: TDM, FDM, CDM, or WDM. Multiplexing techniques are also applied to software operations, such as: while the multi-threaded information stream is transmitted to the device or program.

The controller 213 of the end microwave module 21 transmits the signal to be transmitted to the far-end microwave module 22, and then the signal is excited by the far-end microwave module 22 through the digital microwave radio frequency module 223, so that the device is integrally converted into digital microwave for transmission, the speed is high, the cost of remote transmission is low, and the self-networking access equipment is deployed in a distributed manner, so that the safety of the self-networking equipment is more convenient and the adaptability is stronger.

To minimize the space required and reduce the overall hardware cost, the near-end microwave assemblies 21 typically share a power supply module, a controller card, a common client interface module, and a plurality of modem cards, each of which is connected to a digital microwave transceiver, so that the single near-end microwave assembly 21 with multiple modems supports a maximum of multiple channels.

In this application, a single digital microwave transceiver supporting two-channel aggregation in one radio frequency circuit chain may have two cables connecting the digital microwave transceiver directly to two modem cards. From both channels are combined into a common radio frequency chain and then to the antenna output. Similarly, for the receiver side, the antenna receives signals from two channels combined in one radio frequency chain at the other digital microwave transceiver, and then splits these signals into two baseband Rx signals. Note that the two channels may be side-by-side or have a certain channel spacing.

Note that a digital microwave transceiver without an antenna, commonly referred to as a radio frequency unit, is provided on the remote microwave assembly 22. The microwave module 22 may also include an integrated circulator at the far end that provides better isolation between the transmitter (Tx) and receiver (Rx) and better return loss at the antenna port, and relaxes the rejection requirements for both the Tx and Rx filters.
