Mitsubishi Electric And NTT DOCOMO Achieve World's First 27Gbps Throughput In 5G Outdoor Trials


Mitsubishi Electric Corporation (TOKYO:6503) and NTT DOCOMO, INC. (TOKYO:9437) announced today that they have achieved what they believe to be the world's first (as of today) 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 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.

Key Features



  For outdoor trials using the 28GHz band, Mitsubishi Electric used an antenna system with 16-beam spatial-multiplexing technology*. Base-station antennas installed on the wall of a building directed beams to mobile-terminal antennas installed on the rooftop of a vehicle.


  The trial was the world's first successful wireless downlink transmission at maximum data rates of 27Gbps and 25Gbps for per one mobile terminal when the communication distance was 10m and 100m, respectively.

Future work
Indoor trials using 28GHz band in multipath-rich environments during fiscal year ending March 31, 2019.

A peak data rate of 20Gbps is required for 5G mobile communications. One technology that promise to meet this need is massive-element antenna systems technology, which enables multi-beam spatial multiplexing where multiple data streams can be transmitted in parallel to mobile terminals.

Mitsubishi Electric and DOCOMO have jointly undertaken "The research and development project for realization of the fifth-generation mobile communications system − 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.
