Abstract :
We present the site-specific signal strength measurement results for path loss, shadowing, and fading in 2.4GHz band under typical harsh environment (high temperature 40-50 C and humidity 80-90%). We use spectrum analyzer Rohde & Schwarz FSH8 and InSSIDer (free software for WLANs). Measurements are taken in indoor and outdoor environments at various locations on different times of the day. An empirical channel model has been derived from these measurements that characterized the indoor-outdoor wireless channel which is suited for broadband multihop communications. This paper provides information that would be useful for the design and deployment of wireless mesh network in Qatar University.
