Visban Joins NTT Docomo's Millimeter Wave Initiative Dmwi
Docomo's dmwi framework now has a partner whose multi-hop repeater system targets the coverage and deployment cost problems that keep millimeter wave confined to dense urban and industrial sites.

Visban Inc., a Tokyo deep tech company founded in September 2022 and led by President and CEO Suk-Bae Cha, has joined dmwi, a millimeter wave initiative launched by NTT Docomo. Through dmwi, Visban will contribute its millimeter wave repeater technology and V-Mesh, a system of orchestrator-controlled repeaters linked in a multi-hop configuration over RF-on-Glass, and take part in demonstration experiments and technical verification.
Millimeter wave carries the wide bands that 5G uses for high-speed, large-capacity links in dense urban areas, large facilities, industrial applications, and fixed wireless access. Its short reach and sensitivity to buildings and walls make coverage expansion difficult, and deployment costs are an issue.
Visban's V-Mesh links multiple orchestrator-controlled repeaters in a multi-hop configuration using its RF-on-Glass technology, with an AI orchestrator adjusting each repeater to network conditions. The company says the aim is to expand coverage while minimizing large-scale additions of base stations and optical fiber.
