A new radio access protocol and network architecture for mobile packet data

A novel mobile data technology designed to support low-cost, hand-portable wireless data terminals is reviewed. The end-to-end service, the radio protocol, and the fixed network architecture are described. The radio protocol incorporates specific features to simplify hardware design, and the fixed network architecture provides for economical rollout. The UK implementation of the network is described, and a novel communications service is introduced, based on a mobile packet data network but effectively delivering two-way message paging to the user
