Wired cellular telephone system
First Claim
1. An apparatus for reducing electromagnetic radiation from cellular telephones, comprising:
- a cellular telephone interface configured to be communicatively coupled to a cable television (CATV) network and further configured to couple with a cellular telephone such that the cellular telephone is communicatively coupleable to the CATV network;
wherein when a cellular telephone is coupled with the interface, the cellular telephone may communicate with at least one network element in a cellular network over the CATV network with at least reduced Radio Frequency (RF) cellular signal radiation compared to a direct cellular RF communication with the at least one network element in the cellular network.

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.

11. A method for reducing electromagnetic radiation from cellular telephones, comprising:
-
coupling at least one cellular telephone with a cable television (CATV) network without RF cellular signal radiation with a cellular telephone interface; and communicatively coupling the cellular telephone interface and at least one network element in a cellular network over the CATV network, such that communication between the at least one cellular telephone and the at least one network element is operable with reduced Radio Frequency (RF) cellular signal radiation compared to a direct cellular RF communication with the at least one network element in the cellular network. - View Dependent Claims (12, 17, 20)
