China Mobile, Intel and Huawei have completed interoperability and development testing (IODT) of the 5G New Radio (NR) standard, the trio announced in a joint statement. The trial was conducted at the China Mobile Research Institute and incorporated massive MIMO multi-antenna technology and used C-band spectrum. The firms described the multi-vendor test as ‘full protocol, full channel and full procedure’, noting that 5G network and 5G terminals from different vendors could perform functional tests and implement further 5G service tests.
Huang Yuhong, VP of China Mobile Research was quoted as saying of the trial: ‘The success of this interoperability test can provide more kinds of terminals for the follow-up China Mobile’s 5G scale test, and also [provide] a large-scale verification of 5G. China Mobile will launch the first pre-commercial terminals in 2019, which will play an important role in such areas as mobile broadband, industry video and smart manufacturing.‘ Huawei’s 5G President Yang Chaobin added: ‘3GPP 5G NR based interoperability testing will further promote the commercial process of 5G. Huawei will actively work with operators and industry partners to promote the maturity of China’s 5G industry and help operators to obtain 5G business success.’
In a related development, meanwhile, China Mobile has signed a one-year frame agreement with Finnish vendor partner Nokia to support the cellco’s infrastructure upgrade plans as the operator looks to tackle growing data traffic demand and prepares the way for 5G and more cloud and IoT-based services. The deal, valued at around EUR1 billion (USD1.17 billion), will see Nokia provide China Mobile with mobile, fixed, IP routing, optical transport and customer experience management technologies.
