The term 5G refers to the fifth generation of mobile technology. With promises of faster browsing, streaming, and download speeds, as well as better connectivity, 5G may seem like a natural evolution for our increasingly tech-reliant society.

But beyond allowing us to stream the latest movies, 5G has been designed to increase capacity and reduce latency, which is the time that it takes for devices to communicate with each other. 

For integrated applications, such as robotics, self-driving cars, and medical devices, these changes will play a big part in how quickly we adopt technology into our everyday lives.

The mainstay of 5G technology will be the use of higher-frequency bandwidths, right across the radiofrequency spectrum.

In the United States, the Federal Communications Commission has auctioned off the first bandwidth — 28 gigahertz (GHz) — that will form the 5G network, with higher bandwidth auctions scheduled for later this year.

But what does 5G have to do with our health?

In this Spotlight, we look at what electromagnetic radiation is, how it can impact our health, the controversy surrounding radiofrequency networks, and what this means for the advent of 5G technology.
