It is already being experimented with. It is called Ultra-Wideband (UWB) technology. It is already approved by the FCC for consumer use but it still has a few bugs. Intel, Belden and many other companies have worked together on this. Now all they have to do is put aside their egos and come up with a compatable format. Once the UWB is in play, don't be surprised if the 802.11n...or 802.11x takes over. Cables are quickly comming to pass. That is why Belden invested a lot of money and resources in UWB.
