Downlink Coexistence Performance Assessment and Techniques for WiMAX Services from High Altitude Platform and Terrestrial Deployments
We investigate the performance and coexistence techniques for worldwide interoperability for microwave access (WiMAX) delivered from high altitude platforms (HAPs) and terrestrial systems in shared 3.5 GHz frequency bands. The paper shows that it is possible to provide WiMAX services from individual HAP systems. The coexistence performance is evaluated by appropriate choice of parameters, which...
متن کاملPerformance & Capacity of Mobile Broadband WiMAX (802.16e) Deployed via High Altitude Platform
This paper investigates the performance and capacity of a WiMAX 802.16e cellular system deployed via High Altitude Platform (HAP WiMAX) through extensive simulations. HAP WiMAX link performance is evaluated for a wide range of channel conditions in terms of elevation angle and signal to noise ratio (SNR) through a comprehensive link level simulator based on 802.16e. The obtained results are the...
متن کاملExperimental verification of optical backhaul links for high-altitude platform networks: Atmospheric turbulence and downlink availability
Optical backhaul downlinks from high-altitude platforms (HAPs) are investigated. An experiment demonstrated the advantages of optical links: a small and lightweight terminal with low power consumption was launched to the stratosphere and data transmitted down to a ground station at a rate of 1:25 Gbit=s: Owing to the chosen system parameters and the high budget margin, disturbing turbulence eff...
متن کاملDownlink Performance of WiMAX Broadband from High Altitude Platform and Terrestrial Deployments sharing a common 3.5GHz band
A downlink performance of deploying WiMAX (IEEE802.16a) both from High Altitude Platforms (HAPs) and from terrestrial base stations sharing the 3.5GHz band is presented. It is shown how these two wireless communication configurations can coexist with either adjacent or overlaying coverage areas. The performance of each deployment is affected by factors such as transmission power, antenna beamwi...
متن کاملSofter Handover Schemes for High Altitude Platform Station (HAPS) UMTs
An important property of high altitude platform station (HAPS) Universal Mobile Telecommunications Systems (UMTS) is that unlike terrestrial tower based systems. interference is dependent on the antenna characteristics of HAPS rather than the terrain features (i.e., shadowing) in the service area. In this paper. we exploit this unique HAPS property to propose simple and effective adaptive softe...
