60GHZ RF CATV REPEATER

摘要

A method and system for extending the reach of cable television (CATV) broadcast networks via 60 GHz (nominally) wireless radio frequency (RF) repeaters (422 and 424). An original CATV AML broadcast signal, having a bandwidth of 55-860 MHz, is up-converted to a millimeter wavelength RF signal having a nominal base frequency of 60 GHz (57-64 GHz) such that the up-converted signal has a bandwidth of the base frequency plus the bandwidth of the CATV broadcast signal (e.g., 60.055 - 60.860 GHz). This up-converted signal is then transmitted from a transmitter antenna (422) to a receiver antenna (424), which collectively defines the end points of a point-to-point wireless link between network nodes. The up-converted signal is then down converted at the receiver (418) end to produce a repeated CATV AML broadcast signal having substantially the same characteristics as the original signal. The radio transmission operations may be performed in accordance with FCC part 15.255 transmissions, enabling unlicensed operation.
