Abstract
A novel communication system including mobile units distributed within a wireless communication network which are connected to a packet switched network (e.g., the Internet) via a proxy server is disclosed. The proxy server converts unicast data packets coming from the packet switched network to multicast data packets being transmitted to the mobile units, and is also responsible for the overall management and control of the communication system.
