WiSA
From Wikipedia, the free encyclopedia
WiSA is a hardware and software standard for wirelessly transmitting digital audio from an audio source to wireless speakers.[4] The standard is promoted by the Wireless Speaker and Audio Association (WiSA Association),[1] which comprises consumer electronics manufacturers, retailers, and technology companies.[5] The standard is based on technology from the WiSA Technologies corporation.[1]

WiSA removes the need to run speaker wires or RCA cables between an AV receiver (or similar device) and speakers in a home theater or home audio setup, though independent power to the speakers is required.[4]
