EXTENSION DEVICE, BASE STATION AND NETWORKING METHOD THEREOF, AND ANTENNA FEEDER SHARING SYSTEM

摘要

Disclosed in the present invention are an extension device, an antenna feeder sharing system, a base station and a networking method thereof. The extension device includes a reception input port and a reception output port, wherein the reception output port is used for connecting a higher level base station when a base station is cascaded for networking, in order to receive the uplink signal from the higher level base station, and the reception output port is used for connecting a lower level base station when the base station is cascaded for networking, in order to transmit the uplink signal processed by the present base station to the lower level base station. According to the present invention, it is ensured that the performance of the base station is constant, meanwhile the networking can be accomplished just using cables, and therefore the installation difficulty is reduced. When the frequency used by the base station is increased and the capability of the base station is enhanced, the original antenna can be directly used for networking, in order to implement the antenna feeder sharing system without setting a new antenna. Therefore the number of the antennas used is decreased and the cost of networking is reduced.
