Health Concerns
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.

Famous quotes containing the words health and/or concerns:
“Publicity in women is detestable. Anonymity runs in their blood. The desire to be veiled still possesses them. They are not even now as concerned about the health of their fame as men are, and, speaking generally, will pass a tombstone or a signpost without feeling an irresistible desire to cut their names on it.”
—Virginia Woolf (1882–1941)
“The human heart concerns us more than the poring into microscopes, and is larger than can be measured by the pompous figures of the astronomer.”
—Ralph Waldo Emerson (1803–1882)
