Summary:
High Altitude Platform Station (HAPS) is a new emerging type of communications stations that requires a new spectrum planning. Under agenda item 1.20 of next World Radio Conference 2012 (WRC-12) HAPS spectrum allocation is proposed to be identified in the range 5 850 ? 7 075 MHz for gateway link only. However, this proposed frequency is already saturated by Fixed Satellite Service (FSS) uplink, rendering HAPS gateway to be a victim of such a scenario. In this paper a developed coexistence methodology is introduced based on the use of overlapping spectrum emission masks coupled with the additional attenuation of interfering signal due to protection from local clutter. The enhanced prediction will result in a significant reduction in the required separation distance and introduces frequency isolation
