U.K.’s plan to deal with Huawei 5G provides an uncertain course for Canada to consider

By cautiously allowing Huawei into only select parts of its 5G cellular networks, Britain is charting its own course in cybersecurity, while seeking to appease both China and the U.S.

But the unique nature of the British strategy means it is untested and could yet prove impossible to carry out.

And as Canada moves closer to its own decision on whether to allow the Chinese telecom manufacturer into this country’s 5G systems, Britain’s plan will serve as an example to either follow or avoid.

“They are putting together a policy for themselves which, on paper, is logical,” said Catherine Rosenberg, the Canada research chair in future internet at the University of Waterloo. “But is it going to work the way they want? It’s unclear.”

The U.K.’s announcement on Tuesday amounts to letting Huawei halfway in the system.

Identified as a “high-risk vendor” by British officials, the Shenzhen-based telco will only be allowed to provide equipment used in the outer layer of Britain’s 5G networks, such as transmission facilities. Huawei gear will be banned from the brains of the operation, known as the core components.

With current 4G technology, only the core equipment processes user information. The outer tier — known as the edge — beams cellular data between devices.

But here’s where it gets complicated — and potentially cumbersome for Britain. Higher-speed 5G is designed to cut down on latency by integrating some processing functions on the edge of the network, effectively blurring the line between core and edge.

Rosenberg said U.K. mobile networks could indeed choose to only purchase Huawei equipment to perform transmission functions in 5G networks.

But she questioned whether the plan would achieve its intended goal. The next-generation cellular technology is “more and more software-oriented” and “edge-based,” said Rosenberg, who also holds the Cisco research chair in 5G systems.

In vehicle terms, it’s like banning a certain manufacturer’s parts from being used in a car’s engine, only to buy tires from the same company. And with 5G, it’s as if engine parts are now being installed in the wheels.

The U.S. has long contended that China could access Huawei’s technology to spy on — or even shut down — foreign telecommunication services. China has always denied these claims.

The fifth-generation technology raises the stakes, as it’s not only expected to provide higher speeds on new 5G-enabled smartphones and other communication devices, it’s also set to form the basis for a deeper presence of the internet in everyday life. A 5G-enabled “internet of things” is meant to allow for more smart devices, self-driving vehicles, as well as tech-based solutions in health care and beyond.

Despite 5G’s projected ubiquity, the thinking behind Britain’s plan is this: if Huawei doesn’t supply core system components, then it won’t have access to sensitive data. But from country to country, the perception of the technological reality of 5G seems to vary based on political considerations. (Source: CBC)
