Abstract:
1. An antenna interface system for a base station, said system comprising: a first radio-frequency (RF) antenna unit configured for transmitting transmit data over a first communication band and for receiving receive data over the first band and receive data over a second communication band; a first antenna cable connected to the first antenna unit, said first antenna cable collectively carrying the transmit data of the first band and the receive data of the first and second bands, and said first antenna cable not carrying the transmit data of the second band; a first RF filter unit connected to the first antenna cable and configured to pass the transmit data of the first band on to the first antenna cable and to filter the receive data of the first band and the receive data of the second band collectively carried by the first antenna cable for separate output; a second RF antenna unit configured for transmitting transmit data over the second band and for receiving receive data over both the first and second bands; a second antenna cable connected to the second antenna unit, said second antenna cable collectively carrying the transmit data of the second band and the receive data of the first and second bands, and said second antenna cable not carrying the transmit data of the first band; and a second RF filter unit connected to the second antenna cable and configured to pass the transmit data of the second band on to the second antenna cable and to filter the receive data of the first band and the receive data of the second band collectively carried by the second antenna cable for separate output.
