Non-terrestrial networks (NTN) are being integrated into 5G standards and, according to standards body ATIS, “maximize the inherent value of 5G networks by solving coverage problems and difficult use-cases that ground-based infrastructure alone cannot address.” While NTN are often assumed to be LEO or GEO satellites, there is also another, closer-to-earth option in development: HAPS, which fly in the earth’s stratosphere.
What are HAPS?
HAPS stands for High-Altitude Platform Station, although they are also sometimes referred to as High-Altitude Pseudo Satellites. HAPS carry telecom payloads and can provide stratosphere-based connectivity to devices on the ground. So far, HAPS have been used largely for temporary coverage, such as during disaster recovery, but companies working in the space hope to use them for more enduring and reliable coverage in unconnected areas.
