I’m pretty darn aware of the REAL capabilities of Bluetooth 4.0, the claims of extended range are under ideal conditions, with nothing else around. I work for a company that designs wireless communications methods. GPSK is never going to give you long range communications, and it was never designed as such. OFDM is the way to go, which is used by Wi-Fi, your cable modem, etc.
With Wi-Fi, cordless phones, and microwave ovens all around, there’s plenty of interferers. Bottom line is it won’t be reliable outdoors for large scale unless you are always close or you are standing out in the desert. I live on a canyon, and and still pick up Wi-Fi from houses all the way across it (there’s a golf course in the canyon).
Eventually Wi-Fi Direct will kill all this “long range” bluetooth nonsense, with longer range and better interoperability, but I digress.
I’ll be interested to see the results of people who try to use it outdoors.
