Development of an empirical path loss model for a deployed 2.63GHz WiMAX network in a rural environment

In this paper, an empirical path loss model is proposed for a WiMAX network operating on a carrier frequency of 2.63GHz for a rural terrain condition. This model is developed by means of real time measurements which are conducted on a deployed BSNL WiMAX network at Kuchinda, Sambalpur district, Odisha. The real time data like received signal strength indicator (RSSI),Carrier to interference plus noise ratio (CINR) are collected at different locations of that network and with the help of those data, a new real time path loss model is proposed using MATLAB simulation software. The proposed path loss model is compared with existing path loss models for identifying the one which closely approximates with it. The value of path loss exponent, path loss due to shadowing are calculated. Also, the relationships between RSSI, CINR and distance between base station (BS) and customer premise equipment (CPE) are formulated.
