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.

the 5g standard includes many frequencies, including long range 2g-like ~400Mhz ones

I'm a ham radio operator; it just feels weird hearing someone call 400 MHz "long range." Above, say, 60 MHz I wouldn't count on anything beyond line-of-sight anyway, though I suppose the lower in the UHF band you are the more likely you are to punch through leaves and such.

hahah everything is relative I guess.

I did once talk to Ukraine from some woods in North Carolina on 20 meters (~14 MHz) So when you say "long range radio" to me I think in hemispheres.
