In this paper, we will discuss the business model design for the deployment of capacity-driven services from high altitude platforms (HAPs). Key factors of successfully delivering the HAP services will be investigated in terms of coexisting with current major wireless broadband and cellular network operators in a long term perspective. A partnership-based business model will be proposed and demonstrated...
This paper proposes a novel beamforming technique for the high altitude platforms (HAPs) mobile communications to generate adaptive radio coverage worm-shaped cells covering the main highways which carry a heavy traffic of mobile users. This technique is based on pattern summation of individual low- sidelobe narrow beams - which constitute the desired cell pattern - weighted by an adaptive amplitude...
The focus of this paper is on the integration of High Altitude Platforms (HAPS) into a terrestrial UMTS system to effectively support MBMS applications. Its main objective is the efficient allocation of transmission resources to multicast traffic streams (by suitably selecting terrestrial and/or HAP channels) while still preserving the desired Grade of Service of background unicast traffic. Specifically,...
Cellular communications using high altitude platforms will predominate the existing conventional terrestrial or satellite cellular systems but requires some optimization especially in the, radio coverage cellular design. In this paper either spot-beam antennas or antenna phased arrays are used in the radio coverage which is optimized in directing their beams to satisfy mostly uniform cellular layout...
