@strypey I know the basics about radio transmission and well wireless transmission simply doesn't have
the bandwidth for acceptable connection speeds if you have more than ~40 wireless clients/km².

Starlink is one example - it's acceptably fast if there are only a handful of stations in each cell, but as soon as many people start
actually using it, the connection speeds drop substantially.

LTE and 5G use many techniques to increase the possible bandwidth, but as soon as enough people actually start using it in an
area, the speeds drop substantially, even to the point where emergency callls start getting dropped.

There is a lot more bandwidth available in currently unused extremely high frequency bands and lab testing has shown promising
results (although that doesn't necessarily mean practical devices will be possible to manufacture), but due to patents, any working
technology will be unusable until at least 20 years after practical devices are made available.

The atmosphere also tends to aggressively attenuate extremely high frequencies, so I'm not sure if such bands will be practical to
use from satellites.

If you want emergency announcements during natural disasters, the most reliable thing would be one big AM tower that can transmit an AM radio signal to the whole country (with maybe text announcements also encoded into the audio stream).

In many natural disasters you're really on your own and should focus on being prepared to handle them, as even if you can make a call for help, that's no good if the emergency services are too overwhelmed to help you.


Instead the fibre internet rollout should continue, as that has enough bandwidth and is quite tolerant of natural disasters if properly installed.
