    • 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.
    • 一种码分多址电信网络,包括在私人房屋内的底层基站和多个覆盖宏基站。 底层基站包括GPS接收机和移动单元接收机。 底层基站使用其地理位置来获得识别底层基站的预选距离内的基站的信息。 它使用移动接收机来测量基站的信号强度。 它自动选择专用于下层站的信道或分配给宏基站的未使用信道或导致最小干扰的宏基站频率作为工作频率。 移动单元接收机可用于识别底层站处具有最低信号电平的频率。
