Japanese operator SoftBank and compatriot company Kyocera conducted a backhaul system verification test utilizing the millimeter-wave band allocated to SoftBank for 5G services.
In a release, the telco said that the test was conducted using SoftBank base stations located in Akiruno City, Tokyo, from January to April 2022.
The companies said that the aim of the test was to verify the effectiveness of millimeter waves as a backhaul line; establish end-to-end communications from the CU (Centralized Unit, aggregation node)/DU (Distributed Unit, distributed nodes) server to the communication terminals; confirm the effects of weather changes such as rainfall and snowfall and collect data for the development of commercial products conforming to O-RAN Alliance specifications.
