Deployment and Capacity of Mobile WiMAX from High Altitude Platform

Abstract

In this paper, we investigate the deployment and capacity of delivering mobile WiMAX based on IEEE 802.16e-2005 from aerial platform such as High Altitude Platforms (HAPs). A urban scenario and an suburban scenario with mobile broadband usages as complement or substitute to the fixed Internet connection are developed to compare the delivery of broadband services from terrestrial and aerial platforms. A deployment strategy is based on maximizing and meeting the networking traffic demand and coverage area. In the end, a comparison based on cell radii and capacities between services from aerial platforms and existing terrestrial based solutions, such as universal mobile telecommunications system (UMTS) and high speed packet access (HSPA) is proposed. Currently, most research has been done to develop advanced technologies to enhance standards to support a higher data rate in a cost-effective way for wireless communication systems. From analysis and investigation, aerial platform can provide a cost-effective solution for a large area with a medium to high traffic demand.I.

Deployment of an aerial platform system for rapid restoration of communications links after a disaster: a machine learning approach

“…Results establish the feasibility of first respond communications using a flexible aerial platform. The authors in [25] exploit the ABSOLUTE project which relates to emergency 4G communications to aid disaster traffic management using a tethered aerial platform. In their experiment an aerial platform is inflated and launched at a 300 m altitude within 10 min.…”

“…Considering aerial platforms in any emergency situations with an optimized propagation model is scarcely reported in the literature, let alone considering QoS and GoS. This section aims at first to introduce our physical model for re-establishing communications with aerial [14,18,25] MIMO limited consideration for diversity gain [38,44] QoS Various techniques to minimize power consumption [17,32,35] Trade-off between pathloss and power consumption to guarantee long lifespan connection for WSN [35,45] GoS -Lack of consideration for aerial platforms platforms in the immediate aftermath of a natural or man-made disaster and then set up an initial, non-optimized, ATG propagation model. Figure 1 illustrates through the use of the 3D Remcom Wireless InSite software tool our physical model in action.…”

“…where H represents the radial vector of the RBF network, h n is a multivariate Gaussian function, C is the centre vector of the network, and B is the radial width vector. Equation (25) represents the weight vector of the network:…”

CINR Performance of Downlink Mobile WiMAX IEEE 802.16e Deployed Using Coexistence Cellular Terrestrial and HAPS

“…In practice, there is unavoidably power spilling outside the coverage area, which can cause interference to other cells. In this paper, we employ a directive antenna pattern in [1], [2], [20]- [22], which can ensure more power radiated in the desired directions and decrease the power radiated towards undesired directions, on both the HAPS and ground user [23]- [26]. Antenna models are presented in (1) and (2), respectively.…”

“…Providing worldwide interoperability for microwave access (WiMAX) in the 3.5 GHz frequency band via HAPS is an effective step to provide wireless broadband communications [1]- [4]. In these literatures, coexistence performances of deploying WiMAX via HAPS and terrestrial have been evaluated in terms of capacity and channel performance.…”
