US Patent:

6438359, Aug 20, 2002

Filed:

Jul 19, 1996

Appl. No.:

08/684651

Inventors:

Bernard Bossard - New York NY
Charles Brand - Colts Neck NJ

Assignee:

Cellularvision Technology Telecommunications, L.P. - Freehold NJ

International Classification:

H04B 102

US Classification:

455103, 455115, 348723

Abstract:

Reliable transmission of signals in a multi-channel system is achieved by transferring signal inputs from a defectively operating or inoperative transmitter to another transmitter which continues to transmit other channels. At least two transmitters are operated normally, each transmitting its own block of channels. A sensor detects when the output of one transmitter is improper or non-existent, and causes a change-over switch to operate. Operation of the switch adds the block of channels which had come from the one transmitter to the other (or one or more) of the transmitters, so that the remaining transmitter or transmitters now provide all the channels.

International Classification:

H03F 316

US Classification:

330277

Abstract:

Certain GaAs FET devices are employed to accomplish low noise performance and simultaneous high power handling capability, i. e. high dynamic range performance, in an amplifier using larger GaAs FET devices. Such devices are incorporated in different circuit configurations to achieve amplifiers having, simultaneously, a low noise figure, higher input/output intercept performance, higher output power, and improved ruggedness toward high input interfering signals, while not sacrificing other highly desirable terminal characteristics, (i. e. gain, VSWR, etc. ).

International Classification:

H04J 100
H04H 104

US Classification:

370487

Abstract:

A combination of broadband program materials, such as TV, plus digital communications services of all types, are broadcast to a cell in the same frequency band, such as 27. 5 to 28. 5 GHz. The combination of all the transmitted channels have a combined bandwidth substantially exceeding the frequency band. At least some of the channels are transmitted with two diversity characteristics different from those of other channels. In one embodiment analog signals transmit the broadband services, preferably using wide deviation FM modulation, the FM channels filling the band. By choosing carrier frequencies selectively, between 5 and 9 T-1 digital channels can be broadcast in each FM channel when polarization is the same. Differing polarization of digital and FM signals in the same band can enable selection and detection of the desired one of a full spectrum of digital signals, or any one of the analog signals.
