In January 2020, the National Cyber Security Centre (NCSC) issued new guidance restricting Huawei's ongoing involvement in UK Mobile Networks. As BT/EE's 2/4G RAN is approximately 2/3 Huawei, the telecoms group required a RAN vendor strategy rethink. In July, further policy was advised which gave a stop purchase date for Huawei 5G equipment and an outright removal date requirement. Curiously, Belfast is the first area to get BT/EE's new RAN vendor - Ericsson.
