What is the maximum range of Class 2, 2.5 milliwatt (mW) Bluetooth devices?

Explanation:
Bluetooth range is tied to how much power the device can transmit. Class 2 devices use up to 2.5 milliwatts, which gives a typical maximum range of about 10 meters in open space. So 10 meters is the best match for this power level. Signals can drop with walls, interference, or crowded environments, so real-world range may be less, but it won’t normally reach 20 or 50 meters unless the device has higher power (Class 1) or exceptional conditions.
