While technically possible to blanket an area with RF jamming signals, I think both sides depend on the signals so much that the nuisance of jamming the signals outweighs the benefits. Kind of like with GPS signals - our military could (and occasionally does) jam those signals during a conflict, but we rely on it so much that it's more useful to keep it working.
