Advanced Wireless IP Access System (WIPAS) for Fixed Wireless Access (FWA) - Broadband Access System for Triple Play Services by "Fiber + Radio"-

In 2003, Nippon Telegraph and Telephone Corporation (NTT) commercialized the Wireless IP Access System (WIPAS), a point-to-multipoint Fixed Wireless Access (FWA) system utilizing the 26-GHz frequency band for home and Small Office-Home Office (SOHO) users to provide broadband Internet access service. WIPAS provides a best-effort type IP access service with the transmission rate of 80 Mbit/s by combining wireless technology with optical fiber. For the next stage, the authors are developing the Advanced WIPAS, a more high-speed FWA system that provides triple play services; broadband IP service, 4-class Quality of Service (QoS) and HDTV video transmission services.
