Abstract
A localized wireless gateway system provides wireless telephone communication and provides access to a public packet data network, such as the Internet, for at least voice telephone type communications. The wireless gateway system includes a number of base stations, essentially built around computers with digital transceiver circuitry, which provide an air interface to a number of digital terminal devices. The terminal devices communicate audio information in a standard digitized and compressed data format. The base stations provide two-way communications of the audio data over a public packet switched data network, either directly or via a local area network and a server coupled to the public data network. A server and local area network provide local voice and data communications as well as voice and data communication access to the public packet data network.
