Global leap to 4G and 5G would cut off phone access for millions of vulnerable people.

  • Telecom companies aim to profit from the 2G-to-5G transition as governments worldwide face pressure to free up mobile spectrum.
  • Vietnam is the latest country to shut down 2G by offering free 4G phones to the poor.
  • India and South Africa have expressed concern that the strategy would cut off phone access for millions of vulnerable people.

I am still baffled by these idiots after I learned how 5g works. It isn't just frequencies increases (I could see why someone might be sceptical about this one). The main difference is simply using another protocol which allows to send more bits with a single signal.

If there is any thought to it, it usually goes something like "Radio is/was fine because it's kilo/megahertz, Wifi/5G is gigahertz waves of electromagnetic radiation.(?!?!)"

Could always point to the Terahertz electromagnetic radiation source plugged into their nearest lightbulb socket and ask how that doesn't hurt them.

Not yet another protocol invading me brain!?? For all I know the different pattern of signal does things to my delicate nets.

I already had to contend with the fridge and garage door
