Kind Code:
A
Abstract:
The tap antenna unit includes signal splitting circuitry, coupled to a coaxial cable which is servicing a consumer electronic device, such as a television set, for splitting off a signal from the coaxial cable; a filter coupled to an output of the signal splitting circuitry for selecting a low-level sharp frequency band in the energy spectrum of the coaxial cable; circuitry for demodulating a signal carried by the low-level frequency band; circuitry for modulating the output signal onto a carrier in an unlicensed frequency band; and an output antenna which is coupled to the modulating circuitry and which is capable of transmitting the output modulated signal over a limited transmitting-receiving area.
