Advanced Wireless IP Access System (WIPAS) for fixed wireless access (FWA) - broadband access system for triple play services by “fiber + radio” -

Abstract

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-GHZfrequency bandfor 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, we 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. We made prototype models of the Advanced WIPAS and test the prototype models in 2007. This paper describes the system concepts and specifications of the Advanced WIPAS. Furthermore some results ofprototype verifications are shown.

“…Design of WT that mainly focuses on a unique antenna and RF module for a point-to-multipoint (PtMP) FWA system known as Wireless IP Access System (WIPAS) was described in [70,71]. To improve the performance of WIPAS, an advanced WIPAS was presented with system specifications and concepts in [72,73]. Furthermore, prototype models were developed and evaluated.…”
