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:
“Medication alone is not to be relied on. In one half the cases medicine is not needed, or is worse than useless. Obedience to spiritual and physical laws—hygeine [sic] of the body, and hygeine of the spirit—is the surest warrant for health and happiness.”
—Harriot K. Hunt (1805–1875)
“Much unhappiness comes from walking alone. When there are several, it’s somewhat different. I must get into the habit of listening to others, for what the others say concerns me, too.”
—Alfred Döblin (1878–1957)
