Sprint plans to test a High Altitude Platform Stations (HAPS) communications system for six months starting in November.
Documents filed (PDF) with the FCC show the carrier has asked for a “special temporary authority” to conduct demonstrations of experimental transmitters using spectrum frequencies ranging from the 1.9 GHz personal communications service (PCS) band and the 2.5 GHz broadband radio service (BRS) and educational broadband service (EBS) bands.
The tests will be conducted with HAPSmobile, a joint venture between Sprint’s parent Softbank and AeroVironment that was formed in 2017.
Sprint said it will be testing a HAPS system’s ability to maintain a stable LTE link with ground equipment over the island of Lanai, Hawaii. It will also test handover capabilities with end user equipment and signal coverage over the island.

Though initial tests would focus on LTE, Sprint’s proposed use of 2.5GHz spectrum raises the possibility it has an eye toward using the technology for 5G.
