A high bitrate optical downlink was performed by the stratospheric optical payload experiment (STROPEX), a part of the EU CAPANINA project. The STROPEX objectives were to design and build the necessary hardware to demonstrate an optical backhaul downlink from a stratospheric platform to the ground and to carry out channel measurements on the link. A successful measurement campaign at ESRANGE near Kiruna, Sweden achieved all of these objectives. The transportable optical ground station received an almost error free 1.25 Gbit/s data signal from the payload over a distance of 64.3 km with a bit error rate of better than 10 -9 . This paper gives an overview of the stratospheric optical payload experiment, focusing on the airborne free-space experimental laser terminal (FELT). Additionally, the successful measurement campaign is described and the operation of the experiment is outlined.

“…It has the advantages of higher line of sight capability and wider service coverage compared to terrestrial systems, and a much shorter propagation distance including more flexible deployment compared to satellite systems. [1] They are easily deployable and easy to maintain, which is why they offer a good alternative for network operators who need to find the ways to get more coverage to satisfy the increasing demand for more capacity.…”

High Altitude Platform (HAP) is a platform for many purposes e.g. remote sensing, communication, science experiment etc. Several countries are likely interested in research and development of HAP for communication since it combines the benefits of terrestrial and satellite systems. The objective of this paper is to find the suitable altitude to operate zero-pressure balloons, a type of high altitude platform which maintainable of desired altitude, for longest duration. This paper presents an experiment of zero-pressure balloon including design and development. The main parameters considered in this study are wind data and RF propagation. The wind data has been collected from several sources: from daily weather balloons recorded for 5 years and from the experimental balloon flights. This paper will discuss the suitable altitude for operating the zero-pressure balloons for longest duration without any control system. This paper shall also recommend altitude for further study.

“…As the evolution of next-generation networks (NGN) promises the integration of heterogeneous wireless terrestrial and aerospace technologies [4][5][6], employing quasistationary high altitude platforms (HAPs) [7] as radio-relay nodes in the stratosphere is a potential and attractive solution for the interconnection of existing infrastructures [8][9][10]. Previous work on relaying through HAPs considered a multitude of scenarios, such as the provision of surveillance, monitoring, maritime, and third-generation (3G) cellular serviceslinebreak [10][11][12][13][14].…”

Next generation wireless communication networks intend to take advantage of the integration of terrestrial and aerospace infrastructures. Besides, multiple-input multiple-output (MIMO) architecture is the key technology, which has brought the wireless gigabit vision closer to reality. In this direction, high-altitude platforms (HAPs) could act as relay stations in the stratosphere transferring information from an uplink to a downlink MIMO channel. This paper investigates the performance of a novel transmission scheme for the delivery of mobile-to-mobile (M-to-M) services via a stratospheric relay. It is assumed that the source, relay, and destination nodes are equipped with multiple antennas and that amplify-and-forward (AF) relaying is adopted. The performance is analyzed through rigorous simulations in terms of the bit-error rate (BER) by using a recently proposed 3D geometry-based reference model in spatially correlated flat-fading MIMO channels, employing a hierarchical broadcast technique and minimum mean square error (MMSE) receivers.
