Fujitsu joins Evenstar Open RAN program Fujitsu is joining the Evenstar Open RAN program, submitting its 5G Massive MIMO radio units (RUs), which will be tested, validated and listed on the TIP (Telecom Infra Project) Exchange Marketplace in the second half of 2022. Massive MIMO increases spectral efficiency and will liberate more network capacity, as well as extending coverage, but supporting it with Open RAN interfaces has been a key performance challenge. “Fujitsu will provide 3.5 GHz RUs that support O-RAN standardized interfaces. With 64T64R antennas, the Massive Multiuser MIMO radios will deliver higher spectral efficiency, better coverage and lower interference at the cell edge than traditional radios,” the company said. Evenstar is an initiative set up by TIP and…
