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
celphones are Class II bluetooth devices, the lowest power output level type
Actually, there'e a Class III, with lower power yet. Nominal range is about 1m.
almost all I have looked at are class II so the headset's will work in a vehicle. the class III 1 meter range would be barely useable for the headset on a person's belt let alone in a car where the phone can easily be 1.5 to 2 meters away.
The opulence of the front office door varies inversely with the fundamental
solvency of the firm.
