They are not exactly "micro locations" (as far as I concern), it's more like proximity (did something get close?). And I think people should set their expectations of BTLE straight. There could be different kind of receivers. It could be something plugged into the wall and it doesn't have to consider battery consumption any more. And if the transmitter is transmitting at a high enough frequency, an iphone running in background mode could still pick up a signal really quick and conserve battery at the same time.
