System for the transmission and reception of directional radio signals utilizing a gigahertz implosion concept
First Claim
1. A non-cellular, line-of-sight broadcast system for providing programming services to subscriber receivers in a unitary service area, comprising:
- a plurality of spaced apart transmitter sites, each site having a transmitter and a directional transmit antenna, each said transmit antenna having a directional, line-of-sight radiated pattern focused toward said service area, all of said transmitters broadcasting on the same carrier frequency, said carrier frequency greater than one gigahertz,a programming feed system connected to each of said transmitters for providing a substantially identical programming signal for broadcast by each of said transmit antennas, anda plurality of said subscriber receivers at respective fixed sites in said service area, a first group of said subscriber receivers having the directional receiving antennas thereof focused toward a first of said transmit antennas which first transmit antenna provides the best reception of said programming signal for the subscriber receivers in said first group and a second group of said subscriber receivers having the directional antennas thereof focused toward a second of said transmit antennas which second transmit antenna provides the best reception of said programming signal for the subscriber receivers in said second group.

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.

7. A non-cellular, line-of-sight broadcast system for providing service to subscriber receivers in a unitary service area, comprising:
-
a plurality of spaced apart transmitter sites, each site having a transmitter and a directional transmit antenna, each said transmit antenna having a directional, line-of-sight radiated pattern focused inward toward said service area, and each transmitter site having at least one directional receive antenna focused toward said service area for receiving a subscriber signal, all of said transmitters broadcasting on the same carrier frequency, said carrier frequency greater than one gigahertz. a programming feed system connected to each of said transmitters for providing a substantially identical programming signal for broadcast by each of said transmit antennas, and a plurality of said subscriber receivers at respective fixed sites in said service area, a first group of said subscriber receivers having the directional receiving antenna thereof focused toward a first of said transmit antennas which first transmit antenna provides the best reception of said programming signal for the subscriber receivers in said first group and a second group of said subscriber receivers having the directional antennas thereof focused towed a second of said transmit antennas which second transmit antenna provides the best reception of said program signal for the subscriber receivers in said second group, and each said subscriber receiver having a directional transmit antenna focused toward a one of said transmitter sites for transmitting said subscriber signal to one of said directional receive antennas at said one of said transmitter sites. - View Dependent Claims (8, 9, 10, 11, 12, 13)
