Just as everyone is feeling comfortable with WiFi, WiGig is coming in 2013. If you go to YouTube and type “Panasonic WiGig” in the search box, you can see Panasonic’s demonstration.

The difference between the two is speed. With WiGig, you could take your iPad out to the car and within 60 seconds, beam a full-length movie to other tablets hanging off the passenger seats. The trade-off is distance. The range for WiGig is only 3 to 10 feet, compared to 65 feet for WiFi. And WiFi penetrates walls. WiGig doesn’t.
