Application Area Expansion in Quasi-Millimeter Wave Band Fixed Wireless Access System

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

“…We aim to improve transmission speed from 46 Mbit/s to approximately 180 Mbit/s. When we developed existing WIPAS, we evaluated the LOS ratio of an AP mounted on a telephone pole and a wireless terminal (WT) mounted on a wall of the customer premises in simulations and field investigations [6]. In a cell with a 700 m radius in a typical residential area (low profile residential area) in Japan, the LOS ratio of an AP mounted on a 15 m high pole to a WT mounted 6.5-7 m high is approximately 70% [7].…”

“…FWA systems based on IEEE 802.11 [6] have been developed, and are being provided to home users. The equipment costs of any FWA system based on IEEE 802.11 b are low, but such systems are afflicted by unstable link quality because these systems utilize the industrial, scientific, and medical (ISM) bands.…”
