Kind Code:
A
Abstract:
The invention discloses a distributed smart antenna system comprising an antenna array consisted of N antenna elements, N radio frequency transceivers and feeder cables used to connect the both. First, N antenna elements and N radio frequency transceivers are grouped according to cell coverage range and traffic volume. Then antenna element groups are distributed on different places of coverage range of same wireless communication system base station, including different buildings or different floors of same building; but use same baseband digital signal processor. Each antenna element group can have one to M antenna elements. In this way, advantage of smart antenna can be thoroughly developed, and during improving cell coverage, system capacity is increased and system cost is decreased.
