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:
“Plants are the young of the world, vessels of health and vigor; but they grope ever upwards towards consciousness; the trees are imperfect men, and seem to bemoan their imprisonment, rooted in the ground.”
—Ralph Waldo Emerson (1803–1882)
“American thinking, when it concerns itself with beautiful letters as when it concerns itself with religious dogma or political theory, is extraordinarily timid and superficial ... [I]t evades the genuinely serious problems of art and life as if they were stringently taboo ... [T]he outward virtues it undoubtedly shows are always the virtues, not of profundity, not of courage, not of originality, but merely those of an emasculated and often very trashy dilettantism.”
—H.L. (Henry Lewis)
