Abstract

Wimax stands for Worldwide Interoperability for Microwave Access and operate in 2.3GHz, 2.5GHz, 3.3GHz, 3.5GHz (licensed) and 5.8GHz (unlicensed) frequency bands. Path loss models can be used to find Received Signal Strength (RSS) which is an important factor in deciding handover. If RSS is less than a particular threshold value then handover decision is to be taken. For our analysis we have taken Free space Propagation, ECC-33, COST 231 Hata, COST 231 W-I and SUI models compared w.r.t. different environment (high density, medium density and low density) and different height of receiving antenna (2m, 6m, and 10m). Then RSS value are calculated in three environment and comparing RSS with particular threshold we determine which of these models is suitable for avoiding number of handover.
