Australia has banned Chinese telecommunications network equipment manufacturers Huawei and ZTE from supplying operators in their 5G deployments.
The government did not name specific companies in its statement but said that because 5G will make mobile networks so important to everyday life, and be used to connected industrial and safety systems, that the use of certain suppliers was an unacceptable risk.
At the heart of its concerns is network architecture.
Future releases of 5G will allow operators to move certain functions from the core to the edge of the network, a process which will reduce latency and enable applications like the Industrial Internet of Things (IIoT), connected cars and even robotic surgery.
The Australian government argues that by moving these functions away from the relative security of the core to the edge increases the possibility of threats and means that current measures to mitigate them will become less effective.
“While we are protected as far as possible by current security controls, the new network, with its increased complexity, would render these current protections ineffective in 5G,” said the statement
