As the wireless telecommunications companies ramp up their 5G rollouts, they are beginning to pull the plug on their 3G networks. 2022 is the end of the line for the venerable cellphone service.

The radio frequency at which 5G operates in the US is close to that of an important piece of aircraft equipment, called radio altimeters.

Airplanes use radio waves to determine how far off the ground they are. New 5G cellphone services come close to the same frequencies the airplanes use. Here’s how that can be a problem.

5G is 10 times faster than 4G, promising better wireless internet access. It’s also expected to put the Internet of Things revolution in high gear.

‘Teleoperated’ HGVs combine the efficiency of automation with the safety of human oversight.

The murky blobs visible with today's wall-penetrating radar could soon give way to detailed images of people and things on the other side of a wall – and even measure people's breathing and heart rate.

A new way to harvest power from 5G networks could make many of the batteries that power our devices a thing of the past, researchers say.
