Someone didn't read the article.

Hehe, just kidding. But seriously, Super Wi-Fi is a Alliance over seen standard using the 802.11u protocol on 470-690Mhz range of bandwidth which is no where near G's and N's 2.4 and 5Ghz. It will interfere with your G and N no more then your 2.4 interferes with your 5Ghz. Now don't get me wrong, there are lots of things it WILL interfere with, heh, just not Wifi. Some cellular tech, and would probably horrible to any cable networks disposed to ingress (AZ I am looking at your).
PS. Hahaha, ****e "having a natural inclination or tendency to something; disposed;" is seen as a bad word. Wow, Dlink knows better slang then I.
