Even though Bluetooth Smart has a range of 150ft., the actual range fluctuates due to barriers such as magnetic frequency, metal objects, or other obstructions that can weaken or block signal strength. Also some phone manufactures may limit a phone’s Bluetooth reception range to avoid draining the phone’s battery.
