While operators race to deliver ever-faster connections to people who are already well-served, billions of potential customers remain without any reliable signal at all. Is ubiquitous coverage, not speed, where the opportunity lies?

5G is still letting users down. However, a recent controversy suggests that consumers may understand phone signal even less than we had thought. Where has all the phone signal gone – or was it never really there to begin with?

5G delivers increased mobility, performance and security – so why aren’t telcos doing more to capitalise on these capabilities in the private sector? We break down the essentials of private 5G, and how telcos can seize the initiative.

What happens to the telecoms industry if mobile networks reach overcapacity and data traffic starts to fall? We might already be in that situation. Has cratering data traffic growth brought us to "the end of telecoms history?"
