The US is trying to impose a global ban on China’s 5G network supplier Huawei, citing fears of cyber espionage
At the 2019 Mobile World Congress in Barcelona the other week, all the talk was all about 5G, the Newest New Thing in mobile communication technology. If at this stage your eyes begin to glaze over, then you have my sympathy. But stay tuned: this stuff is more intriguing than you might think. And aspects of it are deeply mysterious.
First, some basics. Like most technologies, mobile communications goes in “generations”. At the moment, we are supposedly in the fourth generation – which is why you sometimes see “4G” next to the network signal icon on your phone. I say “supposedly”, because if you live outside a major conurbation, you are more likely to see “3G”, which means that you are stuck in the previous generation, despite the fact that the industry likes to pretend that 4G is ubiquitous.
BT announced it was removing Huawei kit from parts of its 4G network. But Japan and Germany have proved less compliant
