Would is that GSM (Global system for Mobile Communication, global mobile communication), UMTS (Universal
Mobile Telecommunications System, UMTS), CDMA (Code Division
MultipleAccess, CDMA), TD-SCDMA (Time Division-Synchronous Code Division
Multiple Access, the CDMA of time division synchronous), WIMAX (Worldwide Interoperability for
Microwave Access, micro-wave access to global intercommunication), TDD-LTE (Time Division Duplexing Long-Term
Evolution, time division duplex Long Term Evolution), FDD-LTE (Frequency Division Duplex Long-Term
Evolution, FDD Long Term Evolution) (2G, 3G, 4G) plurality of wireless networks standard Long Coexistence, in order to reasonably utilize
Limited transmission equipment and existing base station resource, reduce CAPEX (Capital Expenditure, capital expenditures) and
OPEX (Operating Expense, operation cost), it is to avoid the repeated construction of resource, supports multiple wireless network standard and smooths
The application of the Multi-Mode Base Station of evolution upgrading is increasingly becoming the development trend of wireless base station.
Multi-Mode Base Station adopts BBU (Base Band Unit, baseband processing unit) and multimode RRU (Radio Remote
Unit, Remote Radio Unit) framework, using unified hardware platform, including unified physical dimension, power supply structure, machine frame
Management, exchange plane, the Ir (Infrared between indoor baseband processing unit (BBU), radio frequency unit (RU Radio Unit)
Ray infrared ray) interface penetrated using CPRI (Common Public Radio Interface, common public radio interface) base band
Frequency interface standard.Because the speed of each wireless network standard I/Q (In-phase/Quadrature, inphase/orthogonal) data is each
Differ, by the CPRI frame of mixed mould, (the Time Division Multiplexing time-division is many with single wireless network standard TDM
