Abstract
A system for providing enhanced multi-function, simplex or duplex RF wireless coverage of a service area, while operating at gigahertz frequencies, employing audio, video or telemetry programming, or any combination thereof; using AM, FM, Digital or Single Sideband modulation, or any combination thereof; from multiple transmitting sites located in a pattern around the outer perimeter of the service area to be provided coverage. All RF transmitter stations assigned to a given service area are fed substantially identical programming with each station employing a directional transmitting antenna thus producing a service area and thereby providing the basic implosion characteristics of the system. A highly directional antenna is employed at each customer's receiving location focused on its optimum transmission site. System vertical, horizontal or circular antenna polarization compatibility provides service area coverage consistent with minimum interference and signal distortion. A choice of three types of subscriber interface devices provides: Option (a) one-way incoming signal reception only; Option (b) incoming signal reception plus an outgoing return capability for, but not limited to, telephone and other two-way interactive services such as facsimile, and computer networking services, games of skill, telebanking, teleshopping, teleconferencing and pay-per-view television program services; Option (c) provides all of the features of Option (b) plus a built-in two-way facsimile communications system and a telephone answering machine for incoming calls as part of the subscriber interface package.
