Wireless data services are poised for tremendous growth, accelerated by both the Internet and the rapid build-out of the necessary infrastructure. To support this growth, it is critical to design applications, protocols and system architecture that are adapted for a wireless operating environment. In this paper, we identify the key issues and challenges in implementing systems for providing wireless data services, and present design approaches and principles. As a concrete example, we describe our design and implementation experience with WDS, a prototype we have built for providing wireless data services to cellular phones over cellular SMS channels.
