Abstract

This paper compares the performance and complexity of two methods of steering an array of aperture antennas on a high altitude platform for the provision of broadband fixed wireless access using cellular type frequency reuse. The first method is to steer all antennas individually to maintain the boresight at the required cell centre. The paper also presents a second method of compensating for aperture antenna pointing error due to lateral and vertical displacement of the platform from the nominal station using only four actuators plus a gimbal that can correct for roll, pitch and yaw of the platform. Results for signal strength, CIR and handovers are given for both scenarios and conclusions drawn.
