First off the gain of the antenna is quite low for a "1 mile away" hack. if they had a custom bi-directional amplifier that was not only a preamp on the incoming signals but bosting the transmit I would start to agree.
I can also see 1 mile away with a dish antenna giving them more in the 25-30db gain range... espically considering that they are losing at least 3db in the cable it's self.
It's a neat idea, and the close range (100-500 feet) possibilities with a basic directional antenna are certianly poss
I was there - holding the Nokia out in front of me. TechTV was there filming the test from both sides. It will appear on The Screen Savers at some point.
We used a high gain, 19dBi, panel antenna attached to a Linksys Class 1 Bluetooth adapter - picture [wifi-toys.com].
Using this equipment, last week we transferred a few pictures from 3300 feet (1 km). This week we bluesnarfed from about 5300 feet (1.08 miles).
The whole point of these experiments is to show that Bluetooth can go a lot further than previously suspected. Witness the 55.1 mile link [wifi-toys.com] using 30 mw wifi.
Lack of details is because it's in Wired News. Look for a writeup on www.wifi-toys.com [wifi-toys.com] later today.
