DOCOMO, Huawei claim ‘world first’ with outdoor 5G trial

6 Nov 2017

Japan’s largest mobile operator by subscribers and revenue, NTT DOCOMO, and Chinese ICT solutions provider Huawei Technologies have announced a ‘significant field trial milestone’, completing the world’s first 5G Ultra-Reliable and Low-Latency Communication (URLLC) field trial in the 4.5GHz frequency band (C-Band), using a new radio interface of similar features such as 3GPP 5G New Radio (NR) air-interface. The pair say the field trials demonstrate that ‘the current 5G trial system over 4.5GHz can meet the performance requirements for URLLC as defined by the International Telecommunication Union – Radio Communication Sector (ITU-R),’ and will pave the way for a widespread deployment of macro cell sites to support URLLC and the creation of a ‘solid foundation for the extensive application of 5G NR across various vertical industries’. The 5G URLLC trial was conducted in Minato Mirai 21 District, in Yokohama city.
