UWIN-universal wireless infrared network system

Abstract

Wireless data communications are being implemented by the complementary technologies of RF and IR. The RF options provide larger area coverage than wireless optical communications but are limited in full bandwidth throughput to about 5 Mbps whereas the infrared systems described in the present paper using IR-LED have achieved data rates up to 125 Mbps. Token ring, Ethernet and PABX (voice) are thus achievable with relatively low cost components at distances up to 400 m for all-weather operations. We present typical case studies of installations for PABX and network building-to-building wireless connectivity locations.
