Agents discovered electronic devices in five locations in and around the city that could be used to disable cellphone towers. The system could also be used for criminal activities.
This seems like something meshtastic would not fall victim to.
Radio falls off quite quickly with distance, so I would think two nodes far away from the jammer would still be able to hear each other because they are closer to each other than they are to the jammer noise.
Depends entirely on the antenna. A jammer just increases the noise floor to above operational levels. A 5db antenna will be more affected to jamming then a 23db antenna because it is listening to a more narrow space.
The distance and location sure have a huge impact, but actual jammers use so much energy energy compared to the well regulated devices. I’m not sure anything comes through.
A good example is drones or starlink jammed in Ukraine. The drones need to change frequencies regularly as the jammer saturate a set of frequency bands. Starlink on the other hand seems to be run with a frequency hopping mechanism, which is more robust by design.
Different areas of tec and use cases, but the principles are the same.
