SoftBank successfully conducts flying telecom base test over Japan

SoftBank has achieved a significant milestone in telecommunications by successfully conducting tests of its high-altitude platform station (HAPS) over Japan. The airship-shaped craft, capable of flying at nearly 20 kilometers for several months to half a year, marks the first successful flight of this kind in the country.

This innovative technology is poised to enhance connectivity during disasters such as earthquakes and typhoons. SoftBank, one of Japan's top mobile carriers, launched the HAPS from New Mexico in the United States and conducted trials over Muroto in Kochi Prefecture from August 23 to 24. During these tests, the platform demonstrated stable operation of voice, video, and emergency calls, as well as drone usage.

The firm envisions expanding the operational areas and flight times by 2027 and intends to provide communications services to businesses on a regular basis. While NTT Docomo, Japan's largest mobile carrier, is also conducting trials in the Noto region of Ishikawa Prefecture, which was affected by a devastating earthquake in January 2024, SoftBank and NTT Docomo both remain committed to commercializing HAPS.

The potential applications of this technology extend beyond disaster recovery, including labor-saving measures in primary industries and assessing earthquake damage. SoftBank and NTT Docomi are driving the development of HAPS, anticipating its commercialization driven by new industry applications like artificial intelligence and drones. The success of these companies in achieving profitability by securing corporate clients will be a critical factor in the future of this technology.
