Thinking a lot recently, about interesting signal propagation methods.
Typical 2.4/5ghz wireless transmissions being omni-directional (insecure for 1). Of course, not counting you using a yagi steal wifi from far directional distances, or bridge distant buildings
Been thinking about propagating ultrasound in water, between UAV nodes, and have been inspired by this pre-computer technology in the UK. A series of concave stones, used in sequence can propagate signal
