Transmit-only mechanisms are definitely the best way to go to reach the extreme minimum in low power levels. The problem with transmit-only systems is that they are difficult to use in most real-world situations. Once you have deployed a tr

The mesh nodes have to run either in always-on mode (which makes perfect sense if they are powered by, say, a wall socket, which they often are) or in a sampled listening mode. Sampled listening shaves some 98% off from the radio duty cycle
