This paper is meeting the principles of how to design coverage area for Sulaymaniyah city, using a new technology, which named HAPS. It started with small introduction for HAPS with its advantages, compare it with terrestrial and satellite systems, and specify requirements for design. Such as, specify the center of coverage area to find the coordinates. Then, supposed the coverage area for the city, elevation angle, and the location of earth stations which will connect HAPS with other networks and reduce the Interference with Fixed Services (FS) and Fixed Satellite Services (FSS).Mitigation technique of interference is given. Also, path loss and fading loss has been applied to meet the geographic of Sulaymaniyah city.
