There's little evidence that a Huawei 5G ban is the right approach

The UK government is happy to allow Huawei equipment to form part of the UK's 5G network – just not any of the crucial parts, according to leaked discussions from the National Security Council. The United States and Australia have taken much more hardline approach, with complete bans on using Huawei equipment to form any part of their 5G network. What is all the worry about? According to telecoms firm Qualcomm, 5G mobile internet gives a massive speed boost – at least 10 or 20 times greater – over our current 4G networks. As devices start sharing more and more data, from phones streaming data-rich video to self-driving cars, it's vital to have a speedy connection.
