Abstract

Telephone apparatus, including a cable television (CATV) network interface, which is adapted to be connected to a CATV network so as to receive downstream cellular telephone communication signals transmitted at a downstream intermediate frequency (IF) via the CATV network from a base-station transceiver system (BTS) operative in a cellular telephone network. The apparatus includes a telephone interface, which is adapted to connect to a cellular telephone operative in the cellular telephone network via a physical connection.

The apparatus also includes signal conversion circuitry, which is adapted to convert the downstream communication signals received at the downstream IF via the CATV network interface to downstream radio-frequency (RF) cellular telephone signals compatible with the cellular telephone network, and to convey the downstream RF cellular telephone signals to the cellular telephone via the physical connection.
