The driving force behind WiSA is the Summit Wireless chip and module, which will be standard in all WiSA compliant devices. With WiSA 1.0, the chip provides sound at a 96KHz sample rate, at 24 bits to 2.1, 5.1, 7.1 and beyond at up to 30 feet. Summit is on the advisory board for WiSA, along with Silicon Image -- you know, the people who invented a little thing called HDMI. The companies have helped develop WiSA on a broad, 24 channel wireless band that is far removed from Wi-Fi, Airplay, and DLNA transmissions to help provide a traffic free space. The open bandwidth harbors the signal from the interference problems consumers have experienced with previous wireless sound systems: If one of the channels has interference, the system automatically and (we're told) seamlessly moves to the next channel.
But aside from the incredibly clean, unhindered sound transmission we heard from the WiSA system at the Venetian, perhaps what makes WiSA most enticing is its simplicity. Venable says the hardest thing about setting a WiSA system up is pulling the speakers out of the box. We're not quite convinced it's that simple, but it looks pretty close. The system is set-up by two different methods: The first, onboard the more expensive WiSA compliant products, works by having the speakers chirp at each other at a pitch well above the frequency that humans can hear. With this method, wherever you go with your remote control, the system understands and adjusts all the speakers for volume and delay, making any place in your living room the hotspot for surround sound...
See that little box next to those huge speakers? That's Aperion Audio's ticket to what's reportedly a no-compromise approach to wireless home theater. The Intimus 4T Summit Wireless is billed as the only system of its kind to transmit uncompressed 24-bit, 96KHz audio to its 5.1- or 7.1-channel speaker array without having to string wires across the living room. There's no interference and no more than 5ms of lag, even when that wunderkind box is processing Dolby TrueHD or DTS-HD Master Audio. Aperion is still touting an easy setup that can create a sweet spot in awkward spaces. If you like the idea, the only real catches are the $2,999 and $3,499 prices for the respective 5.1- and 7.1-channel systems -- although the outlay may be worthwhile to cut the clutter without sacrificing the finer details of Blu-ray movie soundtracks. 
The coolest trick at CES was Summit Semiconductor's WiSA (Wireless Speaker & Audio) technology and the way it could literally move the sweet spot from the usual front-and-center position off to the side or to the back of the room. It was uncanny. WiSA spreads uncompressed high-res signals wirelessly among powered speakers. You're looking at the power/receiver board that makes it work. WiSA will surface first in Aperion products. The loudspeaker industry would be crazy not to jump on this, especially since it can be built into speaker systems selling for less than $1000.
