A High Altitude Platform Station (HAPS) is a network node that operates in the stratosphere
at an of altitude around 20 km and is instrumental for providing communication services …

This paper provides an up-to-date review of wireless communications service provisioning
from High-Altitude Platforms (HAPs) in rural or remote areas exploiting cellular radio …

The use of unmanned aerial vehicles (UAVs) is growing rapidly across many civil
application domains, including real-time monitoring, providing wireless coverage, remote …

The demand for high-capacity wireless services is bringing increasing challenges,
especially for delivery of the “last mile”. Terrestrially, the need for line-of-sight propagation …

This article is a survey on communication aspects of High Altitude Platforms (HAPs), namely
airships or aircraft positioned in the stratosphere between 17 and 22 km. HAPs can be …

This paper reviews the possibilities of UAV applications to forest-fire fighting in the typical
before-during-after scheme. Before-fire they can be used for monitoring of the vegetation …

In a wireless communications network served by a high altitude platform (HAP) the
cochannel interference is a function of the antenna beamwidth, angular separation and …

This paper looks into the relatively new field of high altitude platform stations. HAPS is seen
as a 'middle ground'between the terrestrial and satellite cases, and aims to exploit of the …

With the increasing interest in wireless communications from solar-powered aircraft-based
high altitude platforms (HAPs), it is imperative to assess the feasibility of their deployment in …
