A New Empirical-Physical Method for Calculation of Path Loss for Fixed Wireless Access in Suburban Areas

摘要

In this paper a new empirical-physical method for calculation of path loss in the fixed wireless access in suburban areas is proposed. It is shown that this method has a relatively good accuracy for high transmitter antennas. Since in fixed wireless access, high transmitter antennas are used, we can use this method for this kind of communications and in special case for systems based on IEEE 802.16a. In this method a new empirical model for calculation of path loss exponent is used which is based on measurements reported in various papers and in contrast to other models, the effect of receiver antenna height in the path loss exponent is considered. The first step of this method is the calculation of path loss for a 2D scenario by using GO{sup}1 and UTD{sup}2 methods with respect to transmitter-receiver distance. Then using new empirical model, path loss exponent is corrected and in this manner, the final path loss is obtained.
