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.
5g > 2g if g is positive
Aktchually g gets simplified so it’s 5 > 2 for any value
If you divide an inequality by a negative number you have to flip the sign.
If you want to divide out the g before knowing if it’s positive or negative you need to make the case distinction.
If you make the case distinction and one branch results in a false statement (5 < 2 in this case), you have disproven the original inequality, or at least discovered a constraint on the original inequality. Then you arrive back at FooBarrington’s statement that includes the constraint :-)
What if g is zero?
Zero g is only available in special airplanes and in space, so not much of a worry for most people.
Damn it! I was dreaming of one day scrolling Lemmy on a 0g connection. You ruined my dreams and I am sad now.
What if g is a complex number?
I don’t believe in such trite charlatanery
