Is Sonos Using Bluetooth?

Fred says he's looking for a device that will pair up with his cell phone and broadcast Bluetooth signal to multiple speakers simultaneously. Sonos tackled this problem many, many years ago of Whole Home Audio; now we see the same thing with Echo speakers,. With Google speaker they have all sort of taken on this idea of just adding multiple speakers to the same stream. Fred: I probably wouldn't recommend eight random Bluetooth speakers synced up because you're just never really going to get a good signal that sounds good across all of these speakers.
