Abstract :In this paper, the performance of HAPs insert ignore into journalissuearticles values(High Altitudes Platforms); UMTS HSDPA insert ignore into journalissuearticles values(High Speed Downlink Packet Access); is studied for different HAPs height h, different cells radius R and two directions insert ignore into journalissuearticles values(0° and 30°); within the cell. The network under study is assumed to have 61 ground cells. It is noticed that, for urban zone users, the effective range is lower than the effective range for users in rural zones for a given modulation scheme. Also it is noticed that in rural zone, the HSDPA can support higher modulation schemes. It is noticed that, when 80% of the base station total power is assigned to the HSDPA service, then, for rural zones three HSDPA users can be supported with the highest modulation scheme insert ignore into journalissuearticles values(3/4 16QAM);. Also it is noticed that, in urban zones, only one HSDPA user can be supported with the highest modulation scheme.
