I already  own a basic WISA system.

How to set it up, in a nutshell: It connects to your TV via HDMI Arc, plug in the usb power. That's it!

The workhorse, in my eyes, is the transmitter. You can buy them anywhere, even on

Amazon as a single device, or part of a system.

Since I already have 5 speakers (which sound incredible), let the reverse engineering begin!

What We Know So Far
  • Transmitter to receiver link uses the U-NII band radio spectrum - 
    • The Unlicensed National Information Infrastructure (U-NII) frequency bands are part of the radio frequency spectrum from 5.150-7.125 GHz defined by the US Federal Communications Commission (FCC). It is used by WLAN devices and some ISPs and radio operators.
  • Audio: 8-channel,24-bit uncompressed audio, delivered at 44.1, 48, and 96kHz sample rates
