Abstract :
This paper introduces a ray-tracing based channel model for 5 GHz which is the promising band for next generation wireless local area network (WLAN). WLAN technology is now becoming a viable alternative to traditional wired solutions even in the office environments. Moreover, the access point (AP) equipped with multiple-input-multiple-out (MIMO) antenna arrays have received great interest for high data rate transmission. Nevertheless, the deployment of APs in this scenario may be quite dense as the system will be capacity limited. Consequently, the links may be relatively short, so that there may frequently be a strong LoS component. In this case the angle spread would be very low, and MIMO may not work very well. Therefore, accurate channel model for MIMO enabled WLAN is of great significance from system level to evaluate an indoor deployment of IEEE 802.11n APs.
