LOCAL WIRELESS COMMUNICATIONS SYSTEM WITH EXTERNAL COMMUNICATIONS LINK |
摘要 |
A wireless communication system using radio frequencies for transmitting and receiving voice and data signal with an internal network with multiple internal communication path, and an external communication path for linking the internal network to an external communications network and is suited to operate in remote locations that are isolated. The internal network contains transceivers that allow for decentralized communication along multiple communication paths within the internal network. If the transceivers are within range, they can communicate directly without the need for a central call switching and delivery center. If the transceivers are out of range, they can communicate via intermediate transceivers that relay the calls to the destination transceivers, eliminating the need for a central call switching and delivery center. The internal network has the capability of communicating with an external communications network, such as a public switched telephone network, a satellite communication system, an emergency radio system and a paging system. |
