Abstract

A range of wireless data services is provided utilizing a thin client portable wireless component, a fixed access point component with client session and connection control and end applications for the client, and a service management component providing user profiles and authentication. Access point components and service management components interconnect via the existing broadband infrastructure. Cellular technologies, unlicensed spectrum, wireless LAN, and N-tier thin-client architectures are integrated, thereby reducing sharply the cost of delivering wireless email, instant messaging services, and multi-tier applications to consumers and business users.
