It amazes me how many competitive wireless standards are vying for the same space. The latest protocol that's getting a lot of attention is Wireless USB. I remember when Wireless USB first hit the scene, maybe four years ago. It was proposed as a "standard," but that wasn't exactly the case at the time. It was one vendor proposing the protocol, agreeing that they would make it open to anyone who wanted to design to it, but it never went through any standards body.
That's not the case with the Wireless USB we're hearing about today. This one does many of the same things that Bluetooth and ZigBee are supposed to do. But of course, it's cheaper, more reliable, blah, blah, blah. How can they all be cheaper, more reliable, etc?
I still say we should stick to the one that's here today, and working today: Bluetooth.
