Field test measurement on 5 GHz band wireless LAN under outdoor mobile environment
A. Yasuda, Shigeaki Ogose · 2006
WLAN (Wireless LAN) is useful access method to realize high-speed data transmission. WLAN is mainly used under indoor environment. In this case, transmission performance such as BER (Bit Error Rate) and throughput are evaluated under non-fading or slow-fading conditions. However, transmission performance of outdoor vehicular environment should be evaluated in order to adopt WLAN to realize high-speed signal transmission systems such as DSRC (Dedicated Short Range Communications) in ITS (Intelligent Transportation Systems). With this motivation, we conducted field test measurement by using officially licensed amateur radio station. In this paper, transmission performance of 5 GHz band WLAN under mobile environment is described based on the results of measurement. Communication systems using WLAN is also described.
