Bluetooth uses the microwave radio frequency spectrum in the 2.402 GHz to 2.480 GHz range. Maximum power output from a Bluetooth radio is 100 mW for class 1, 2.5 mW for class 2, and 1 mW for class 3 devices. Even the maximum power output of class 1 is a lower level than the lowest powered mobile phones. UMTS & W-CDMA outputs 250 mW, GSM1800/1900 outputs 1000 mW, and GSM850/900 outputs 2000 mW.

“Universal empire is the prerogative of a writer. His concerns are with all mankind, and though he cannot command their obedience, he can assign them their duty. The Republic of Letters is more ancient than monarchy, and of far higher character in the world than the vassal court of Britain.”
—Thomas Paine (1737–1809)
