Wall Street Journal in November reported that the US government will be asking wireless and internet providers in friendly countries to avoid telecommunications equipment from Huawei.
BT will remove Huawei hardware from its core 4G network within the next two years amid concerns over China's influence on national telecoms infrastructure. The information was cited by Reuters after initially being published by the Financial Times.
BT started removing Huawei equipment from its network core after this acquisition, it said in an email to CNET.
City A.M. understands BT has not banned Huawei from its 5G operation as a whole, only from bidding for its 5G core network contract.
BT, with whom Huawei has been working with for 15 years, has operated on a principle of different vendors for different network layers, the Chinese company said in a statement.
Huawei-built phone masts and peripheral things like that can stay, but BT has a long-standing commitment in place to not use equipment from the supplier at the very core of its network, due to the unspecified potential security risks of handing an overseas company the keys to your whole network.
"Huawei remains an important equipment provider outside the core network, and a valued innovation partner".
Fellow UK mobile carrier Three last month also announced that it is working with Huawei on a 5G home broadband demo in London.
"Huawei will continue to work with Three UK to bring customers more market-leading commercial applications of 5G", Huawei 5G Product Line president Yang Chaobin said. "I've been to Shenzhen recently and there's nowhere else in the world where you can see the kind of 5G technology developments that Huawei has achieved".
Australia has followed the U.S. in banning Huawei's equipment from the country's 5G roll-out.
In 2010, the British government, Huawei and telecom operators, including BT, established the Huawei Cyber Security Evaluation Centre (HCSEC) Oversight Board, based in Banbury.
It said the process was to bring the EE networks into line with the rest of its business rather than a change of policy. "Huawei has a robust cybersecurity assurance system and a proven track record", it said in the statement.
