NTT DOCOMO Hits 4.5Gbps in 5G Outdoor Trial

NTT DOCOMO achieved a maximum data transmission speed of over 4.5 Gbps using the high-frequency 15GHz spectrum band in a 5G outdoor trial that was conducted last month with Ericsson.

DOCOMO said it its targetting deployment of a commercial 5G network by the Tokyo 2020 Olympic and Paralympic Games in July 2020.

In a separate indoor 5G trial with Nokia Networks on December 18, 2014 to verify beamforming, a technique for more stable high-speed data transmission using exceptionally higher frequencies in the 70GHz band, DOCOMO achieved data transmissions of over 2 Gbps.

DOCOMO also announced that it has agreed with its two newest partners, Huawei and Mitsubishi Electric, to conduct technical verifications of emerging 5G mobile communications technologies using various frequency bands, including lower than 6GHz and extremely high frequencies, called millimeter waves. In total, DOCOMO's 5G trials now encompass eight blue-chip mobile technology vendors, also including Alcatel-Lucent, Fujitsu, NEC and Samsung.
