With non-terrestrial networks (NTN) moving towards increased integration with terrestrial networks for 5G, developments in the NTN field are set to progress beyond both the geostationary orbit (GEO) satellite services of old, and the recently emerged class of low-earth orbit (LEO) satellite constellations. HAPS (High Altitude Platform Systems or High Altitude Pseudo Satellites) may one day fill the gap between Low Earth Orbit (LEO) satellites starting above 400 km, and terrestrial networks. Wireless Watch recently took a look at HAPS showings at MWC Barcelona 2023, which was very much focused on the future of mobile networks, featuring BT partner Stratospheric Platforms (SPL), and Airbus division Aalto HAPS, in a recent piece here.
