I do agree that radio triangulation does happen and this is happening with cell phone all the time. My GrapheneOS phone pretty much stays in airplane mode most of the time.
I know very little about Meshtastic but a one thing seem fairly obvious:
Meshtastic is unlicensed, therefore operates outside the frequency range of commercial equipment such as cellphones. Cell towers can’t be used to triangulate a frequency they aren’t designed to detect.
I have no doubt that Iran’s military has the gear to detect and triangulate Meshtastic.
Anyone can detect any transmitted radio signals. The ARRL books explain how. I’m too lazy to go look at my copy to photograph the section of the physical book in my room. The frequency licensing is totally irrelevant here. That will just be changed and noise will get broadcast over the band. If you keep trying to transmit, someone will find you. You are literally creating a beacon in all directions that points at you. Everyone will be listening, but one by one there will be no one to listen to. This is standard stuff. Every military unit has radio counter measures. You are very limited in real output power already. The big boys will blow you away because they have no such restrictions. It is one of the reasons why there are power limits. Now if you can hide something useful and encrypted near the noise floor, that is one real possibility, but in this age of software defined radio, you are still going to get caught.
You refuse to explain your claim that cell tower can be used to triangulate Meshtastic radios. I’m out. Not wasting any more of my day on this conversation that isn’t going anywhere.
