Abstract

NTT developed the Wireless IP Access System (WIPAS), a point-to-multipoint fixed wireless access (FWA) system utilizing the 26-GHz frequency band for home and SOHO users to provide broadband Internet access service. This service is a best-effort type IP service with the transmission rate of 80 Mbit/s and with the maximum Ethernet frame transmission rate of 46 Mbit/s. Recently, with the aim of further expanding the applications of WIPAS, advanced functions have been developed. The WIPAS service area has been expanded by applying WIPAS technologies in a variety of forms. The radio entrance line is a point-to-point connection using WIPAS equipment that can be applied to extend the broadband access service area where it is impossible or difficult to provide service using optical fibers. This paper describes the service concepts, configurations, and technologies of WIPAS, and illustrates technologies pertaining to added functions and extending the service area of this system.
