Abstract

This paper introduces the system concept and specifications for an enhanced version of the Wireless IP Access System (WIPAS), the Advanced WIPAS, which is a fixed wireless access (FWA) system that provides higher speed and real-time communication for triple play services: broadband IP service, 4class Quality of Service (QoS) especially VoIP services, and multicast HDTV video transmission services. Technical improvements to the system components and media access control (MAC) protocol are described. Results of simulations on the wireless link design show the advantage in terms of the service area compared to the existing WIPAS. Furthermore, some results of prototype verifications are presented.
