Topic: Massive MIMO

Ericsson and KT have successfully completed a trial of mid-band Frequency Division Duplex Massive MIMO (MB FDD Massive MIMO) in Korea. Seven years after KT was among the first global communications service providers to launch commercial 5G with Ericsson solutions, the partners are again setting the pace—this time by prioritizing uplink performance to power the next wave of innovation and lay the groundwork for 6G.

SoftBank Corp. and Ericsson Japan K.K. have deployed an AI-powered, externally controlled coverage optimization system for Massive MIMO at multiple large-scale event venues in Japan, including major arenas and dome-type facilities in the Tokyo metropolitan area, which automatically enhances coverage patterns in response to traffic changes. This follows a successful commercial network trial at the Expo 2025 Osaka, Kansai, Japan (“Expo 2025”).
