The High Altitude Stratospheric Platform (HAPS) is a candidate of post-3G (4G or 5G) wireless communication systems, aiming at creating a new broadcast and communications integrated infrastructure. To provide higher data rate and QoS guarantee to mobile multimedia users, we propose an ATM-based broadband wireless communication system. In order to show the feasibility and investigate the key issues of such an ATM-based HAPS, we have also developed a demonstration system based on a 15m X 4.3m remote-controlled airship. By installing a remote-controlled video camera, a wireless HUB, and a transmitter of digital TV in this airship, we demonstrate a broadband integrated information system which includes (1) remote sensing of the ground, (2) broadband wireless Internet access, and (3) mobile multimedia communication with QoS control. Throughout the demonstration, we mainly investigated the performance improvement by two ATM-based scheduling schemes POSTMAN and MT-WFQS.
