Abstract:
1. A distributed smart antenna system, comprising: a plurality of antenna elements; a plurality of radio frequency transceivers corresponding to the plurality of antenna elements, in one to one ratio, wherein the plurality of radio frequency transceivers connect with a baseband digital signal processor in a wireless communication system base station through a data bus; and a plurality of feeder cables connecting each of said plurality of radio frequency transceivers to a respective one said plurality of antenna elements, wherein the plurality of antenna elements and the plurality of radio frequency transceivers are correspondingly grouped into a plurality of antenna element groups and corresponding multiple radio frequency transceiver groups based on a cell coverage range of the wireless communication system base station or a traffic volume of the cell coverage range or a floor number covered by the wireless communication system base station, wherein each of said plurality of antenna element groups are distributed at different buildings in cells covered by the wireless communication system base station or different floors in a building covered by the wireless communication system base station, wherein each antenna element group connects with corresponding radio frequency transceiver group, and wherein each radio frequency transceiver group connects with the base band digital signal processor through the data bus.
