WiSA

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. However, cabling isn't completely eliminated: powered speakers are required, so the speakers need to be connected to electrical outlets.^[4]
