It introduces the classification and application of remote radio technology on the extensive technical point. Smart antenna and feeder system of TD-SCDMA have many shortcomings in field application
such as much more feeder
limited distance and harden construction
which restricts the application of the TD- SCDMA. Remote intermediate-frequency signal technology and remote baseband signal technology are developed as supplements. Telecom operators can easily build a TD-SCDMA network based on variety technology options.
