No, because they will be too easy to jam.
However, sustaining broad-spectrum jamming over a large area is expensive and impractical.
If the mesh network is wide enough, redundant enough, mobile enough, then traffic can be routed around jammed areas.
Its actually pretty cheap! Its just not useful for anyone. Plus there are point to point and laser communications.
Unfortunately, most mesh networks rely on civility for long range. They just don't have the power to punch through.
It would be relatively easy to jam large areas.
drones can be also shot down and operators radiolocated very quickly
But wouldn't those jammers also disrupt other critical comms in use by those who might do the jamming?
no, because they have separate comms using completely different bands. esp when you're talking about military
Think of a signal jammer as something blasting static. You're only hope of getting around that is playing something even louder. Russian jammers are effective because they don't care about leaving channels open for communication and civil comms. They just blast farts on every frequency.
What works in one dimensional ear canal doesn't work in three dimensional open space.
While we have noise cancelling headphones, have you ever heard of noise cancelling speakers?
Actually my father in-law used to design loudspeaker systems that canceled certain frequencies put out by power plants at different heights along exhaust stacks
I assume the trick is knowing or calculating how far you are from the source your timing to block, and having speakers that are broadcasting away from the source.
Sure that's a weakness but it seems likely these kinds of techs will be plausible solutions even if only in isolated cases.
