Japan’s leading mobile operator by subscribers NTT DOCOMO has reportedly completed trials in Singapore and Thailand aimed at expanding the global adoption of Japanese mobile-network equipment for fifth-generation communications and advanced network services. JCN Newswire writes that the trials were set up by DOCOMO in partnership with Denki Kogyo and Advanced Info Service (AIS) in Thailand, and AGC and StarHub in Singapore. The AIS-focused trials (25 September to 18 December 2019) saw Denki Kogyo deploy ‘metamaterial reflectarray antenna for flexibly designed radio-wave reception areas’ in a 5G test situation, to assess reception intensity and compatibility with the local network environment. In the Singapore trial meanwhile (4 December), AGC and DOCOMO used their jointly developed glass-embedded antenna to carry out a trial of 5G technology for StarHub. The test reportedly confirmed that ‘the unique antenna could be embedded on the windows of buildings to provide mobile coverage in urban areas’.
