Abstract
A wireless data network provides message control center broadcasting over a paging channel covering a wide service area and base stations distributed in said wide service area providing two-way communication over a local channel in local service areas within said wide service area. The wireless data network provides asymmetrical data transmission rates between the base station and subscriber wireless data terminals. In addition, the base stations and wireless data terminals can each transmit at different data rates according to desired range and to minimize probability of collision. In one embodiment, a registration procedure is provided to establish continuous communication between a wireless data terminal and a base station in the local channel.
