Inter-band communication repeater system |
摘要 |
A system and method for converting carrier frequencies of a wireless communication system is provided. The system and method allow expansion of coverage areas of wireless communication systems, such as a mobile/cellular telephone system. In one embodiment, the system converts RF signals in the PCS band to ISM band, and transmits the ISM signals to a distant repeater station. The repeater station receives the ISM signals and downconverts the ISM signals to the PCS band. The PCS signals are retransmitted in a new cell thereby creating a new coverage area.
