Cell Base Station Radio Frequency Channel Selection

摘要

A code division multiple access telecommunications network including an underlay base station in a private premises and a plurality of overlay macro base stations. The underlay base station includes a GPS receiver and a mobile unit receiver. The underlay base station uses its geographic location to obtain information identifying base stations within a preselected distance of the underlay base station. It uses the mobile receiver to measure signal strength of the base stations. It automatically selects as an operating frequency a channel dedicated to underlay stations or an unused channel allocated for macro base stations or a macro base station frequency which results in minimum interference. The mobile unit receiver may be used to identify the frequency with lowest signal level at the underlay station.
