5G in London is so far lagging behind Birmingham and Cardiff, according to research into the tech's early deployment.

According to mobile performance testers Rootmetrics , EE has the fastest median download speeds in the capital of 149.2Mbps, while Vodafone recorded 97.7Mbps.

But EE recorded much higher median speeds in Birmingham of 185.7Mbps , with Vodafone recording 112.2Mbps. Meanwhile, the providers recorded median speeds of 163.1Mbps and 113.6Mbps respectively in Cardiff.

Microsoft has put its weight behind the DNS-over-HTTPS (DoH) security protocol, greatly increasing the likelihood of it becoming a default internet standard.

Trend Micro thinks that there is a vulnerability within non-public 5G networks deployed to
