Abstract

Implementation of communication in a multi-protocol wireless network communication network is performed according to protocols independently selected for forward and reverse communication links. A communication request is made according to predetermined criteria, and a communication link is established responsive to the request. A determination is made of a preferred communication protocol in at least one direction (forward or reverse link). The communication link is established for that direction in accordance with the preferred communication protocol while controlling communication in the other direction independently.
