A Japanese national project for the development of stratospheric platforms (SPF) started in 1998 with the goal of constructing a new communications infrastructure. This paper describes this project, including the purpose, organizational structure, and current R and D activities. It focuses on the SPF-based broadband wireless access systems including the system scenario, system configuration, and services to be supported. Key technologies, such as the onboard multibeam antenna system and channel access schemes, are described.
