Combining data and voice communications on digital wireless networks

Abstract

Growing demand for access to mobile data and the advent of new digital wireless voice/data services motivate the design of a system that handles both voice and data traffic efficiently. We describe the design of a system for wireless voice and data communications. On the network side, we enhance a digital cellular/PCS basestation with a direct data connection to provide data services. On the terminal side, we describe a small, light wireless handset that uses a pen based user interface and handwriting recognition for access to data services.
