British Telecom Is Stripping Huawei Out Of Its Network

UK telecom giant BT is to strip all Huawei equipment from its core 4G network and prevent the Chinese equipment vendor from bidding for core 5G network contracts. The move appears to reflect government concern about the close links between Huawei and the Chinese state, and the worry that Huawei's equipment could be used as a "backdoor" for Chinese spying. 

The vulnerability of the core network may have been far more troubling for government security watchdogs because it is linked to important IT systems that contain information about customer accounts. 

BT is already extracting Huawei Technologies Co. Ltd. equipment from its 3G and 4G core networks. It has already replaced most of the 3G equipment and expects the 4G overhaul to take between 18 months and two years. While BT has reportedly blocked Huawei from bidding for any 5G core network contract, it has not imposed the same kind of restrictions on the radio side, where it is already trialing Huawei's 5G base stations in preparation for its 5G service launch next year. 

The rationale is that any use of Huawei in the radio access network would not come with the same kind of risk posed by the core network. 

Through its EE mobile subsidiary, which it acquired in 2016, BT is understood to use radio equipment from Huawei and Finnish rival Nokia to support its 4G network.  

The latest development would seem to be a major setback for Huawei, which is facing a backlash from government authorities in various Western countries. In the UK, it raises the prospect of a full-blown government ban on Chinese equipment suppliers. 

Many operators have resisted the criticisms of Huawei, arguing that its equipment is rigorously tested in their networks. Service providers frequently cite the Chinese company's technological prowess when explaining their decision to use it. BT's decision to replace Huawei in the core network will focus attention on German incumbent Deutsche Telekom AG, which is similarly understood to rely on Huawei for some core network gear. 

Asked if Deutsche Telekom had a contingency plan in the event of a government ban on Huawei, a spokesperson for the operator said in a written statement: "We are pursuing a multi-vendor strategy for the infrastructure elements used (manufacturers primarily include Ericsson, Nokia, Cisco and Huawei) and have a good mix of manufacturers in the live networks and for the planned expansion." 

"With a view to timely expansion and investment requirements, however, it will be difficult to exclude high-performance suppliers in Germany," the spokesperson added, hinting that any formal ban could hold up the deployment of 5G networks in the country. 

The news from BT comes only a couple of days after Alex Younger, the head of UK intelligence agency MI6, had voiced concerns about Huawei during a rare public appearance at a UK event

"We need to decide the extent to which we are going to be comfortable with Chinese ownership of these technologies and these platforms in an environment where some of our allies have taken quite a definite position," he is reported to have said.

"It's not wholly straightforward."

Huawei and ZTE have been Banned by other Governments
Huawei and ZTE were banned by the Australian government from playing a role in any 5G rollouts in August due to supposed national security issues stemming from concerns of foreign government interference in critical communications infrastructure.
This followed a  5G ban in the US, and the US has reportedly told  Canada to ban Huawei, with New Zealand's Government Communications Security Bureau (GCSB) last week telling Spark that it  cannot use Huawei's technology to deploy its 5G network across the nation under its current proposal.

Huawei in September denied similar reports that the  Indian government had excluded it from taking part in joint 5G trials, saying it is currently proposing a set of solutions to support the government's requirements for a nationwide 5G rollout.

South Korea's largest carrier left Huawei off its list of 5G vendors, with SK Telecom announcing in September that it would be going with Ericsson, Nokia, and Samsung.
