High Altitude Platform Stations (HAPS): The Floating Communication Devices

This article examines the relatively new field of highaltitudeplatform stations. HAPS is considered A"middle ground" between ground and satellite casesdesigned to take advantage of both types of casessystem. Since HAPS is an emerging field, this articlefocuses on the technology behind HAPScommunication System, how it evolved, andcompared it to ground and satellite equivalents. Animportant area what is being researched areapplications that should use HAPS. If it matters, thisis a key issue a business case will be developed forHAPS. It will also focus on global HAPS projectsand research issues. At last, the review summarizesthe future of HAPS for wireless communicationsystems.
