Tldr: different countries wanna do 6g differently. Actually a big problem is the big beautiful bill that just passed in the US. Wifi6e/7 6ghz spectrum that was reserved for wifi got approved to get auctioned off. But it's already a global standard. If us cell cariers buy it up and use it to make faster 6g cell speeds (short distance very high speed). That's going to fragment standards globally.

Cell carriers don't currently use anywhere near all their spectrum they already own.

It's encryption has been broken for some time now, which leaves it vulnerable to some pretty serious security issues. On top of the obvious issue of people with the right know-how just listening to your calls and reading your texts, which you probably don't want.

(It's also how most cops/feds tap phones these days.)

Likely more efficient use of spectrum, which means more clients on a tower without everything grinding to a halt.

I was so disappointed going from LTE to 5G and realizing the speed difference is minimal. I was so hopeful it would be mega faster! Going from gigabit at home to mobile speeds is sad.

this is just personal experience but IIRC I seemed to have much better power consumption with 4G/LTE over anything before. 5G/5G+ is good too but that is likely with recent buildout in my area. Weak signal support I have a hard time gauging as the phone bounces back to LTE where I seem to still have good 5G service.

How about we just don't turn iff 4g or 5g.
