All it has to do is buzz out the bits on a low frequency/low bit rate with the cable working as a long wire antenna. Just give it a little buffer.
A defective ballast in a grow lamp is enough to really fuck up shortwave radio reception in a large area, so it wouldn't take much to send slow speed data on a specific frequency a mile away.
But according to the summary the cable creates a Wi-Fi hotspot. Wi-Fi usually refers to the 802.11 standards. There are frequencies and bit rates associated with these standards. So as fahrbot-bot asled, if they can do this with a small USB cable and get a mile range why are home Wi-Fi routers so bad at covering a house from one end to the other. Remember (again according to the the article) the mile range was supposedly in a city so there would have been several buildings between transmitter and receiver (unless they were on the roof of two buildings I guess).
A mile away? (Score:2)
Okay, it's a cable, how do I get my WiFi appliance to do this.
