Abstract
A system for delivering packetized data in a network dynamically assigns a unique address to a mobile unit, allocates bandwidth within a wireless link by a token scheme and provides forward error correction for the packet. The system wirelessly transports the packets between a base station and an end point which is responsive to a link cell for linking the base station and the end point. The link cell contains a header and a body. The header in turn contains a forward error correction code, a radioport id and a token. The forward error correction code provides error detection and error correction that relies solely on a one-way communication of data bits from a sender to a receiver. The radioport id is a logical id assigned such that each radio-port in a vicinity has a unique id. The token enables the wireless transportation over a selected channel of the packets between the base station and the end point. The token is utilized to allocate the selected channel from a plurality of channels. A method is also described for delivering packetized data between an endpoint and a base station.
