VALIDATION STUDY OF PATH LOSS MODELS ONWIMAX AT 2.6 GHZ FREQUENCY BAND INSUBURBAN ENVIRONMENT FOR CELL SIZEPLANNING

摘要

The radio wave propagation in form of path loss model plays very significant role in planning of anywireless communication network. Measurement of signal strength of OFDM driven WiMAX technology at2.6 GHz band is taken in Suburban Town of India. The results are analyzed and compared with Empiricalpath loss models such as Hata-Okumura, Modified Hata and COST-231Hata. COST-231 model showshighest path loss for suburban environment. These analyzed results establish that COST-231 model issuitable for suburban environment also. Threshold RSSI estimates cell coverage probability in the area.
