Abstract

A cell enhancer for use by one cellular provider in a cellular radio-telephone system includes a wideband amplifier for amplifying both down-link and up-link signals and a filter system for ensuring that signals outside of the cellular bands are not amplified. The filter system includes a wideband filter that passes at least the voice channels assigned to the cellular provider in the cell and a narrow band filter that passes the paging/access control channel in the cell. By using the filter system, signals outside the band assigned to the cellular provider, and particularly signals in the band assigned to the other cellular provider which may be present in the area, will not be amplified by the cell enhancer.
