Abstract:
A terrestrial communication system facilitating one way and/or two-way audio, video or data communication for users within a restricted geographical area with use of frequencies within the microwave range and a relatively low power output, characterized in, that the system comprises at least two local terrestrial satellites (LTS) having high frequency communication equipment substantially corresponding to a conventional geostationary satellite utilized digital transmission techniques, the antenna system of each LTS being located spaced from remaining LTS serving the geographical area to be covered, said antenna system being preferably omnidirectional and arranged for transmission in a substantially horizontal plane, users of the system having directional antenna installation being able to select desired LTS by a change of the directional antenna in an horizontal, rotary plane or vertical plane of inclination thus facilitating that frequencies used by one LTS of the system also are being used by any other LTS included in the system for similar or different communication purposes, thereby increasing the number of communication channels available within a given frequency segment to a substantially unlimited number of channels by inclusion of further LTS covering an intended geographical area.
