MODULAR ANTENNA DRIVER FOR EXTENDING THE AREA OF COVERAGE BETWEEN A BASE STATION CONNECTED TO A CATV CABLE SYSTEM AND CORDLESS HANDSETS

摘要

A modular antenna driver is provided for extending the area of coverage between a base station connected to a CATV cable system and a plurality of cordless handsets. The driver includes a duplex circuit connected to the CATV cable and tuned for upstream and downstream communications with the base station over the cable. A core circuit connected to the duplex circuit includes circuitry interconnected to perform and of sufficient bandwidth to perform communication functions common to at least two different handset types. At least one removable module is selectively insertable into the driver and includes circuitry interconnected to perform communication functions characteristic of one handset type wherein one such module may be replaced by a second module for a different second handset type. In the alternative, multiple removable modules may be simultaneously employed in the driver to permit simultaneous compatibility with a plurality of handset types.
