While they're jamming cell service at Moscow protests, let me tell you what it's like just 650km from the capital.

The terrain is hilly with elevation changes of a hundred meters or more. As a result, you can only get a decent signal (== calls + working internet) at the top of a hill. Move 15-20 meters away from the highest point and the internet just disappears. In the valleys, there might be no signal at all. But people live there too.

Your battery drains way faster with this kind of network. Even with the internet turned off.

The same situation isn't just here, but in dozens of villages around the area.
