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. |

DETAILED DESCRIPTION A broadcast system is provided that utilizes a plurality of RF transmit sites.
These transmit sites are pointed inward and are located to provide the maximum practical percentage of coverage for the population within the broadcast system's desired service area.
Through the present invention, each receiver within the service area will have access to multiple transmit sites.
Through the "implosion" of signals into the service area, improved line of sight reception will be provided.
The present invention employs a Gigahertz Implosion Concept to address the needs of traditional broadcasting systems.
All of the transmitting sites employ directional antennas and are fed substantially identical (time-phased where applicable) programming simultaneously from common or multiple sources.
The use of multiple transmitting locations add a substantial long-term service insurance.
Such insurance is not guaranteed by the traditional system which attempts to provide a like service from the top of the highest point within the service area, using an omni-directional transmitting antenna, as in the Empire State Building example.
A fluid analogy to the operation of the present invention is the practice of mounting multiple directional, and overlapping, water sprinkler heads, generally facing inward from around the outer perimeter of a lawn to provide maximum watering coverage, as compared to locating a single large, omni-directional sprinkler head at the highest central location of the tallest roof peak on the property.
In one aspect of the present invention a system for broadcasting programming to a service area comprises a plurality of transmitters.
Each of the transmitters broadcast a high frequency, directional signal and include a head end transmit antenna.
Each of the transmitters are also being fed substantially identical programming.
The plurality of transmitters are located such that the service area is substantially covered by the plurality of high frequency directional signals that are being transmitted
