Validation Study of Path Loss Models on Wimax at 2.6 GHz Frequency Band in Suburban Environment for Cell Size Planning
The radio wave propagation in form of path loss model plays very significant role in planning of any wireless communication network. Measurement of signal strength of OFDM driven WiMAX technology at 2.6 GHz band is taken in suburban town of India. The results are analyzed and compared with Empirical path loss models such as Hata-Okumura, modified Hata and COST-231Hata. COST-231 model shows highest path loss for suburban environment. These analyzed results establish that COST-231 model is suitable for suburban environment also. Threshold RSSI estimates cell coverage probability in the area.
