How 5G works

There are several theories linking 5G and Covid-19. One simply suggests that 5G networks cause Covid-19, or symptoms of the infection. Another more insidious one is that 5G networks emit radiation that weakens the immune system, making people more susceptible to infection.
To break it down, it helps to understand what exactly 5G is.
5G is a next-generation wireless network that is expected to enable a wave of technologies that will change the way that people live and work -- the potential applications include self-driving cars, remote surgeries and automated factories, though it will be a while before we see those kinds of changes.

The big differences between 4G and 5G are faster speeds, higher bandwidth and lower lag time in communications between devices and servers.


5G signals run over new radio frequencies, which requires updating radios and other equipment on cell towers. Carriers building superfast 5G networks have to install tons of small cell sites to light poles, walls or towers, often in close proximity to each other. So far, the networks have mostly been deployed city by city.
