I can't remember where but someone did a wargame where one side used all this high-tech electronic messaging system while the other side used couriers on motorcycles. The side using the couriers won.

Even low-powered, low-tech stuff can work such as CB's or amateur radios if need be, yeah they can be monitored but if you use codewords and stuff, that could work.
