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.

Location information provided by multiple positioning systems is combined to provide an estimated user location. In performing the combination, location information provided by the positioning system that is currently deemed more reliable is provided greater weight than the location information provided from the other positioning system(s). Alternatively, one of multiple positioning systems is selected to calculate an estimated user location. The selected system is the one that is currently deemed more reliable based on some indicia of reliability. Using either approach, an accurate estimate of a user's location can be provided both in rural areas or other sparsely-populated areas as well as in urban areas or other areas prone to high multipath effects.
