Yeah, I don't understand how this works. My understanding was that mobile phone signals naturally did not travel very far because of the spectrum they used, but maybe that is greatly extended for low bandwidth will LoS instead of ground obstructions.
I wonder what it means for tracking a phone by tower pings.
- cozzyd 3y agoSome mobile bands are as low as 600 MHz, which propagates quite well. The reason mobile phone signals don't travel so far are usually ground obstructions (including the horizon) and a relatively weak max power output (23 dBm probably? At least that's what the modems we use in our private LTE network in Greenland do...) The max power output is regulatory, but also for power reasons.
- yencabulator 3y ago> My understanding was that mobile phone signals naturally did not travel very far because of the spectrum they used That's more about not going through trees etc. If you have a line of sight to a cell tower, what keeps you from connecting is mostly the radio trying to be polite and choosing not to talk to a cell tower that's more than some max time delay away. I assume for this they'll tweak the settings, and satellites are good for line of sight.
