TH30366A - Satellite communication system for local coverage - Google Patents

Abstract

DC60 (30/04/41) Communication System provides effective satellite communications in rural areas. Or populated areas Scattered Or in areas that lack conventional telephone infrastructure Or in use for the purpose Special, for example, covering the airport who uses such area Communicate with satellites via a modular access point Big in Local Area to be Service User sets provide per-user system access. User sets are connected to the point of entry through the local access circuit at Is provided by a point-to-point wireless connection between the sets. User and access point Point of entry, communication switch Go back to local as The internal communication between the users and the connection of the communication cycle. External via connection Wireless versus satellite as appropriate External circuits are provided through the collaboration of satellites, controllers, access point and ground stations. Wireless connection Line between satellites And the point of confluence of the entrance and the belly access circuit Locations may be operating at the same frequency or different if they operate at different frequencies. The frequency converter in the control junction point. Access to different frequencies, compatible with the user set may be Was used to provide access to the system of Operate in a manner that Recording and speech recording release takes place. In the user set itself to avoid the impact of Pseudo-code / decoding Communication systems provide effective satellite communications in rural areas. Or populated areas Scattered Or in areas that lack conventional telephone infrastructure Or in use for the purpose Special, such as covering the airport Users of such area Communicate with satellites via a modular access point In the local event that will be served, the user set provides per-user access to the system. Connected to the access point through the local access circuit at Is provided by wireless point-to-point connection between sets. User and access point Point of entry, communication switch Local round-trip between the user and the point of entry, the point of entry, the local round-trip communication switch is Internally between the users and connecting the communication back and forth to the circuit. Outside via a wireless connection to satellites, as appropriate. External circuits are provided through the interaction of satellites. Controller of the central point, entrance and ground station Wireless connection Line between satellites And the point of confluence of the entrance and the belly access circuit Locations may be operating at the same frequency or different if they operate at different frequencies. The frequency converter in the control junction point. They are compatible with different frequencies. User set may be Was used to provide access to the system of Operate in such a way that the recording and the release of speech recording take place. In the user set itself to avoid the impact of Pseudo-code / decoding
