This paper introduces current and planned mobile data and messaging capabilities of the TDMA Digital AMPS cellular and personal communications standard. In addition to providing more than a threefold capacity increase over the venerable analog AMPS standard by digital transcoding and time division multiplexing, D-AMPS provides a flexible and competitive technological platform capable of significant evolution. The introduction of a digital control channel (DCCH) to D-AMPS via the IS-136 standard increases battery life, adds support for hierarchical cell structures, improves private/public system discrimination, and strengthens support of new revenue generating wireless data and messaging services.

This paper contains Cellular/PCS mobile data and voice requirements with regards to network performance and architecture to suggest that wide area data and voice are convergent rather than divergent. The paper motivates a further integration of the existing Cellular Digital Packet Data and asynchronous data services with todays TDMA/CDMA air-interface standards and within the network and subscriber unit. The paper concludes by suggesting even more extensive voice and data integration based on the B-ISDN model for the future third generation wireless communications systems.
