Abstract:

The paper introduces briefly the importance developments in technology and device of TD-SCDMA since 2006 when the large-scale network testing of TD-SCDMA application started at. And since then, the old technologies of TD-SCDMA have continued improving, the new technologies have come forth continuously, such as multi-frequency, TD-HSDPA, six element smart antenna, multi-cell joint detection, UpPCH shifting, and the indoor distribution technology also has matured gradually. The performances and types of TD-SCDMA device have improved gradually and get abundant by degrees. Radio remote unit and base band unit have become the direction of TD-SCDMA device development.In addition,the convenience has changed appearances in the project implement of antenna feedback system.

Key words: TD-SCDMA, six element smart antenna, radio remote unit and base band unit, TD-HSDPA
