Sceye and SoftBank’s stratospheric test brings HAPS-based direct-to-device connectivity closer to commercial rollout
Executive summary: Sceye and SoftBank Corp. finished a stratospheric connectivity demonstration, flying a HAPS platform more than 15,000 km from New Mexico to Japan and connecting it to SoftBank’s core network. The test proves direct‑to‑device and edge‑computing capabilities of HAPS, reducing reliance on terrestrial infrastructure and supporting future commercial HAPS services.
Who is involved: Sceye (HAPS developer), SoftBank Corp. (telecom partner), and regulatory observers overseeing the flight.
Likely next: Further flight tests to refine payload performance, followed by spectrum licensing discussions and pilot commercial agreements with telecom operators.
Sceye and SoftBank have completed a landmark stratospheric connectivity demonstration in Japan, marking a significant step toward commercializing high-altitude platform station (HAPS) technology. The test involved a Sceye platform flying from New Mexico to Japan — a distance exceeding 15,000 kilometers — and successfully integrating with SoftBank's core network to validate direct-to-device communication and edge-computing capabilities. Conducted under the Sceye Service Test Program, the flight demonstrated that HAPS can backhaul telecommunications traffic without relying on ground-based infrastructure, a critical advantage for expanding coverage in underserved regions. The achievement carries substantial implications for the telecommunications sector. By proving that stratospheric platforms can deliver reliable, low-latency connectivity directly to standard devices, the trial addresses a key technical hurdle for HAPS deployment. This approach could complement existing terrestrial and satellite networks, particularly in remote, mountainous, or disaster-prone areas where building cell towers is impractical or cost-prohibitive. SoftBank's involvement signals serious operator interest in integrating HAPS into future network architectures, potentially accelerating regulatory acceptance and spectrum allocation discussions. Looking ahead, the focus will shift to scaling operations, securing long-duration flight certifications, and defining commercial service models. If subsequent tests confirm consistent performance and cost-effectiveness, HAPS could enter limited commercial service within the next few years, offering a flexible layer of connectivity that bridges gaps between ground and space-based systems.
