The AIRcable Host XR packs a receiver advertised at 10 times more powerful than the average Bluetooth dongle, with nearly 20 miles (or 30 kilometers) of range.
The range sounds a little nuts—and requires an external antenna. With such an involved setup, the unit likely won't do much for you unless you're an industrial firm with a lot of machinery. But think what you could do with 20 miles of Bluetooth. Strap on your Skype headset and go for a drive, or jog with your Bluetooth earphones alone. It's way too much for the average user, but for a creative gadget head with $129 to spare, well, we'll let you dream up the possibilities. [ Aircable ]
