SoftBank Corp. conducted tests in which the 7 GHz band demonstrated that it is suitable for achieving wide coverage and stable communication quality in dense urban environments, the company said in a statement.
With an experimental license, SoftBank launched a test in Tokyo using three experimental base stations compatible with Massive MIMO, along with commercial 5G sites operating at 3.9 GHz and Nokia testing equipment.
The continuity of coverage, communication quality and radio wave propagation characteristics were evaluated.
