Abstract :
Wireless telecommunication systems have rapidly developed their networking capability, enabling better and more advanced services for various wireless telecommunication applications. There are several methods of classifying wireless communication networks based on network usage, technology used, bandwidth, and frequency range. Despite the availability of satellite systems, they come with a few drawbacks such as high costs (for satellites and launch) and technical requirements for non-GEO satellite systems or the possibility of joining GEO satellite systems. Ground systems also have their own set of problems, such as being costly and having potential health and environmental risks. High Altitude Platform Station (HAPS) is a station located on an object at an altitude of 20 to 50 km and fixed relative to the ground. While they have brought a new set of problems, HAPS deployment is fast and incremental, maintenance is easy, and they can be reset and reassigned. The round-trip delay is less than 0.5s, and they can be environmentally friendly (solar). Generally, HAPS operates at an altitude of about 22km, which means a potential service area of over 200 km radius, depending on the altitude. In this paper, we propose a brief review of HAPS, its related technical aspects, and keys introduced by HAPS.
