Path loss characteristics in a civil laboratory building at a frequency of 2.4 GHz

Path loss characteristics in a civil laboratory building at a frequency of 2.4 GHz

This paper presents indoor radio wave propagation characteristics of a large laboratory at a frequency of 2.4 GHz. We performed path loss measurements in two categories namely LOS, NLOS same room and LOS, NLOS different rooms. These categories provide different path loss characteristics in each envi...
