KAUST research develops HAPS deployment guidance for hard-to-reach areas

1 min read ·
In many remote regions, terrestrial infrastructure can only be installed near roads, coastlines, rivers or other accessible areas. This can leave large interior regions with limited or unreliable connectivity. Such gaps may affect not only mobile users, but also applications such as agricultural Internet of Things systems, renewable-energy facilities, environmental monitoring and emergency communications. Researchers at King Abdullah University of Science and Technology (KAUST) and Maynooth University have developed a mathematical framework to guide the deployment of high-altitude platform

KAUST research develops HAPS-borne radar for persistent, real-time disaster monitoring

Researchers at King Abdullah University of Science and Technology (KAUST) have developed a joint trajectory-and-resource optimization framework that enables a high-altitude platform station (HAPS) to carry out synthetic aperture radar (SAR) sensing while carefully managing the limited energy available for flight, radar operation and communication. The team, including Bang Huang, Ki-Hong Park, Xiaowei Pang and Mohamed-Slim Alouini, investigated how solar-powered HAPS aircraft operating in the stratosphere, typically around 20 to 30 kilometers above the ground, could carry SAR payloads to

Connecting large numbers of sensors and wireless devices across deserts, forests, agricultural regions and other areas where fiber infrastructure is difficult or costly to deploy presents a challenge for future Internet of Things networks. Research team including Hao Lin and Prof. Mohamed-Slim Alouini from King Abdullah University of Science and Technology (KAUST), and Dr. Mustafa A. Kishk from Maynooth University, has developed a mathematical framework showing how high-altitude platform stations, or HAPS, could work together with ground gateway networks to create large-scale continuous

KAUST Research Develops Directional-Beam Analysis Framework to Guide HAPS Network Design

High-altitude platform stations (HAPS) can extend wireless service from the stratosphere, but planning a large deployment requires more than estimating one strong air-to-ground connection. As platform and user populations grow, designers must also account for many co-channel interferers, Earth curvature and the directions in which antennas point. That combination makes direct network simulation increasingly demanding: the paper notes that the number of serving and interference links can grow quadratically with the number of HAPS.

Researchers at King Abdullah University of Science and Technology (KAUST) have developed a mathematical framework to guide the deployment of high-altitude platform station networks across islands, coastlines and open maritime areas. The team, including Hao Lin, Mustafa A. Kishk and Mohamed-Slim Alouini, examined how high-altitude platform stations, or HAPS, could support communications in regions where terrestrial networks are costly or difficult to build. HAPS are aircraft or balloons equipped with communications systems and typically operate 20 to 50 kilometers above Earth. Their wide

First analyzed the unique characteristics of non-terrestrial networks (NTN) platforms with impact on network specification, and proposed an efficient distributed coordination framework for heterogeneous NTN, verified by a case study on IAB-enabled heterogeneous UAV networks.

Digital roads in the sky: Stratospheric communication networks would connect the unconnected

1 min read ·
Connectivity is a cornerstone of today’s world – but roughly one-third of the planet’s population isn’t linked up. Bridging that gap has proven challenging, because telecoms are hesitant to invest in the infrastructure to reach remote, sparsely populated areas. One solution is to lighten the load by moving communications infrastructure into the sky, where a network of flying platforms can link remote sites to satellites or terrestrial networks. But these high altitude platform stations (HAPS) technologies have applications and implications far beyond simply connecting rural communities. A HAPS
