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:
“In our great concern about the mental health of children, however, we have overlooked the mental health of mothers. They have been led to believe that their children’s needs must not be frustrated, and therefore all of their own normal angers, the normal ambivalences of living, are not permissible. The mother who has “bad” feelings toward her child is a bad mother.”
—Elaine Heffner (20th century)
“Mr. Christian, it is about time for many people to begin to come to the White House to discuss different phases of the coal strike. When anybody comes, if his special problem concerns the state, refer him to the governor of Pennsylvania. If his problem has a national phase, refer him to the United States Coal Commission. In no event bring him to me.”
—Calvin Coolidge (1872–1933)
