Measurements to design a coverage area by using high altitude platform systems.

This paper proposes the principles of how to design UMTS coverage area for Baghdad city the capital of Iraq country as a case study that occupy area about 204.2 km², by using one of the new technology for providing two wireless bands which are narrowband and broadband communication services as well as for broadcasting services issues with either airships or airplanes techniques which is named HAPs, Viewed from its altitude, HAPs floats within the stratosphere layer in the airspace, positioned between satellite and terrestrial platforms. This study also cosidered the affect of interference with the available broadband technology. It will start with brief introduction for HAPS with its advantages, comparison between HAPS system and other services and specify requirements for design. Such as, enumerate and find the center of coverage area to calculate the coordinates. Then, design the coverage area for the city, and find the radius, elevation angle, and the position of earth stations which will connect HAPS with other networks and all other services location depending on latitude and longitude, finally the reduction of interference technique.
