Abstract:
1. A method of operating a cellular repeater having a variable-gain donor antenna adapted to communicate with a base station, and a server antenna adapted to communicate with a mobile device, the method comprising: receiving, at the donor antenna, communications from one or more available base stations that are available to the cellular repeater; determining a best serving base station from the one or more available base stations; measuring, at the donor antenna, a signal from the best serving base station; adapting a gain of the donor antenna to maximize a signal level of the signal received at the donor antenna from the best serving base station; and adapting a gain of the server antenna to increase a radio frequency isolation between the donor antenna and the server antenna, the adapting of the gain of the server antenna including incrementally increasing the gain of the server antenna until the radio frequency isolation between the donor antenna and the server antenna degrades.
