Abstract

The effect of the changes in the position and inclination of an aerial platform (AP) on the number of users per cell (M) in a code division multiple access (CDMA) cellular system is described. The AP at 21 km uses a multiple beam antenna system to create elliptical cells on the Earth's surface. Vertical errors in altitude of the AP of /spl plusmn/0.5 km cause M to decrease by 1 to 2%, while horizontal displacement errors of up to 0.3 km result in a decrease in M of approximately 1%. An inclination of 5/spl deg/ from the horizontal significantly impairs M by 38%.
