panel discussion


HAPS (High Altitude Platform Station) is expected to be used as a solution to connect the unconnected areas from the stratosphere at an altitude of approximately 20 km, taking advantage of its characteristics of being able to cover a wide area and applying continuous connection even in natural disasters. Various players, including aircraft vendors, network vendors, telecom operators, and academia, are currently conducting research, development, and demonstration to realize HAPS. In addition, ITU-R is studying the expansion of frequencies for the use of HAPS as IMT Base Stations (HIBS) as Agenda Item 1.4 of World Radiocommunication Conference in 2023 (WRC-23). In this session, domestic HAPS providers, research institutes, and overseas experts on HAPS will introduce these initiatives and discuss expectations, challenges, and future prospects for HAPS/HIBS.
