Another trick is to not use strong transmitters, and build a phased array from a mesh-net of sensors.

This needs incredible sync timing, knowledge of positions and knowledge of position of receiver.
- retSava 9y agoSounds like the phased array approach would be expensive, complex, and incredibly hard to get working well in real deployments :)
