The Wireless Speaker and Audio Association (WiSA): CES 2015.
The Wireless Speaker and Audio Association (WiSA) room at CES 2015.
WiSA is an organization that manufacturers join to show that the wireless speakers and components they make support a common standard communications protocol (the WiSA standard). I.E. all wireless amps supporting WiSA can drive any and all wireless speakers that support the WiSA standard.
Looks like they are now branching out to support 5.1 wireless home theater.
