System and method for in-building mobile communications

Abstract

Disclosed is a mobile communication system and method. A base station (BS) transmits and receives signals using predetermined serving frequency signals. A donor module, coupled to the BS, converts output signals of the BS into intermediate frequency (IF) signals and performs a power control operation on the signals and outputs resulting signals to a path. Each of a plurality of remote modules receives output signals of the donor module through the path and converts the signals into serving frequency signals, then outputs the converted signals to a mobile station (MS) within a blanket area. The remote module converts signals received from the MS into IF signals and outputs the signals to the donor module through the path. The donor module converts the IF signals provided from the remote module through the path into serving frequency signals and transmits the signals to the BS. Therefore, the present invention easily removes blanket areas in a building at a low cost.
