THE PROMISE OF 5G WIRELESS SPEED, HYPE, RISK

A much-hyped network upgrade called “5G” means different things to different people.

- 

To industry proponents, it’s the next huge innovation in wireless internet. To the U.S. government, it’s the backbone technology of a future that America will wrestle with China to control. To many average people, it’s simply a mystery.

What, exactly, is 5G wireless — and will you even notice when it comes online?

WHAT IS 5G?

5G is a new technical standard for wireless networks — the fifth, naturally — that promises faster speeds; less lag, or “latency,” when connecting to the network; and the ability to connect many devices to the internet without bogging it down. 5G networks will ideally be better able to handle more users, lots of sensors and heavy traffic.

Before we can all use it, wireless companies and phone makers have to upgrade. Phones need new chips and radio antennas to work with the new network.
