Abstract

In this work, the uplink capacity and the interference statistics are given for an W-CDMA 3-D Air-to-Ground (AG) cellular like network assuming imperfect power control and finite transmitted power. The free space model of propagation is used to calculate the intercellular interference. The uplink capacity has been studied for different frequencies and scenarios. It has been shown that, the effect of rain is to reduce the uplink capacity and the maximum allowable cell radius. Also it is shown that, the frequency of operation should be lower or equal to 2 GHz. For a frequency of operation of 2 GHz, the cell capacity can reach 70 voice users or 46 data users when the cell radius is 350km. The new contribution of the paper is the study of the effect of the imperfect power control and the finite transmitted power on the uplink capacity of the Air-Ground system for different values of outage.
