Extreme Bluetoothing

1 kilometer Bluetooth link

Serving as a true inspiration to Bluejackers and Bluesnarfers everywhere, Engadget pal Mike Outmesguine was able to successfully extend Bluetooth's range (which usually isn't more than 30 feet or so, depending on circumstances) to over a kilometer. He attached a high-gain antenna to a cellphone (Sony Ericsson's T610, to be precise) and was able to successfully connect to a laptop roughly a kilometer away.
