In this paper, an overview of the HAP concept development and HAP trails is introduced to show the worldwide interest and development in the emerging novel technology. A comparison of the HAP, terrestrial and satellite system characteristics is given. Main advantages of HAPs for wireless communication applications are large coverage area, high capacity and cost-effective deployment. Three applicable...
In this paper, we propose to use high altitude platforms (HAPs) for providing wireless broadband communication services in suburban and rural areas, which usually require a cost-effective and economical delivery of telecommunication services. Architectures for HAP communication systems are discussed in terms of service applications and cooperation with terrestrial and satellite systems. WiMax broadband...
In this paper the uplink performance of delivering WiMAX broadband via high altitude platforms (HAPs) cellular system is evaluated and the coexistence capability with terrestrial WiMAX operators is assessed. A coexistence scenario of a HAP and terrestrial WiMAX base stations deployed inside a HAP coverage area with a radius at 30 km will be proposed. A HAP cellular formation with different reuse patterns...
In this paper, performance of providing WiMAX from high altitude platforms (HAPs) with multiple antenna payload will be investigated as well as considering the coexistence capability with multiple-operator terrestrial deployments. A scenario of a HAP and terrestrial WiMAX base stations deployed inside a HAP coverage area with a radius at 30 km will be proposed. HAP cellular formation with different...
The evaluation of uplink performance of delivering WiMAX services from high altitude platforms (HAPs) is presented. System performance is assessed in terms of coexisting capability with terrestrial WiMAX system, employing directive antenna models and optimization techniques. Simulation results show that providing WiMAX via HAPs can effectively achieve 29 dB at the edge of the HAP coverage area with...
