5G When

But again, these frequencies are non-ionising so they’re not harmful to people or other living things. Currently, mmWave 5G is being used in the US and not the UK .

Millimeter waves — often referred to as mmWaves or high-band 5G — are frequencies starting at 24 GHz and beyond . As radio waves increase in frequency, each wave narrows in length. Because of its high frequencies, mmWave has a limited range of only 300 to 500 feet and struggles to penetrate buildings.10 Eyl 2021

The mmWave bands being made available for mobile networks will provide increased performance, better coverage, and a closer integration across multiple wireless technologies from 4G LTE to Wi-Fi, to sub-6GHz 5G, as well as extending to the higher frequency 5G mmWave bands.6 May 2021

Millimeter-wave: High speed, but with a downside The first flavor is known as millimeter-wave (aka mmWave). This technology has been deployed over the course of the last few years by Verizon, AT&T and T-Mobile , though it’s most notable for being the 5G network Verizon has previously touted across the country.
