Line of sight?

Can't see it superceding 802.11N or other WiFI standards. I remotely and automatically update all my software on the Pod, the Pad and the Phone over WiFi. If the devices had to be in LOS for all those updates the convenience would be lost. I like being able to access the Net over WiFi from wherever I have my five WiFi capable devices at the time.

Is this a solution is search of a problem?

My prediction. It will meet a brief and ignominious death.

Get back to me in a year of so if it has gone anywhere.
