Abstract
Abstract A decentralized asynchronous wireless communication system is disclosed for providing voice and data communication that allows flexibility of communication paths for local communication or for communication to external networks. The system makes use of communication docking bays that may communicate in a local mode with other communication docking bays or handsets within a same microcell via signal extenders. In an extended mode, a communication docking bay located in a first microcell of a first macrocell may communicate with a second communication docking bay or handset in a second microcell of the first macrocell via signal extenders and a network extender. In a remote mode, a communication docking bay located in a first microcell of a first macrocell may communicate with a second communication docking bay or handset in a second microcell of a second macrocell via signal extenders and network extenders. The communication docking bays also provide a communication path to a Public Switch Telephone Network and other communication medium. This feature provides an alternate means of connecting a mobile handset to a Public Switch Telephone Network without communicating through a network extender. The system is particularly suitable for operation in rural areas having a low population density.
