Review of Selected Wireless System Path loss Prediction Models and its Adaptation to Indoor Propagation Environments

The advancement in wireless technology has followed diverse evolutionary path all aiming at achieving a better performance and efficiency in mobile environment such as voice, data, file sharing, video and much more. The deployment of wireless network over the years has been on the increase due to continuous improvement in IEEE 802.11 standards. This brings about enhanced data rate and a rise in Wireless Fidelity (WIFI) coverage thus increasing the handling capability for different bandwidth applications per time. Radio propagation is of great importance in wireless networks due to the high cost required to set up a wireless system. It is possible to employ different propagation models depending on factors such as the concerned environment and frequency of operation among others. Signal coverage, antenna gain and bit error rate can be predicted through classification of the radio channel employed. This paper reviewed different propagation model
