Mitsubishi Electric Corporation (TOKYO:6503) and NTT DOCOMO, INC. (TOKYO:9437) have announced that they have achieved what they believe to be the world´s first fifth-generation (5G) mobile telecommunications proof of concept for 27Gbps and 25Gbps maximum throughputs via one mobile terminal over communication distances of 10m and 100m, respectively, using the 28GHz radio frequency, the companies said.
The demonstration was conducted during joint outdoor field trials using 28GHz-band massive-element antenna systems and 16-beam spatial-multiplexing technology with 500MHz bandwidth. The trial took place in Kamakura, Kanagawa Prefecture Japan from September 10 to 28, 2018.
Mitsubishi Electric and DOCOMO have jointly undertaken “The research and development project for realization of the fifth-generation mobile communications system â High data rate and low-power-consumption radio access technologies with higher-frequency-band and wider-bandwidth massive MIMO” commissioned by Japan´s Ministry of Internal Affairs and Communications. To realize 20Gbps throughput using 500MHz bandwidth, they have now collaboratively developed and validated a massive-element antenna system enabling 16-beam spatial multiplexing.
