I guess that's why they want to make them as roof tiles to cover a whole room with multiples of there and have continuous coverage.

- jacquesm 9y agoTwo points: 1) interference 2) efficiency Lots of transmitters will interfere with each other, you'll get all kinds of interference patterns at the receiver which will negatively impact efficiency. And to that point, the second efficiency issue is that you will spend a ton of money to get a trickle of power to those phones, an inductive coupled system in the base of the table would deliver a large multiple because of the tighter coupling (decreased distance, fewer losses because of the medium chosen, electromagnetic coupling is well understood and efficient, acoustic coupling is fraught with all kinds of inefficiencies and hard to make work in a practical setup with useful levels of power).
