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:
“I still need more healthy rest in order to work at my best. My health is the main capital I have and I want to administer it intelligently.”
—Ernest Hemingway (1899–1961)
“The idea that nations should love one another, or that business concerns or marketing boards should love one another, or that a man in Portugal should love a man in Peru of whom he has never heard—it is absurd, unreal, dangerous.... The fact is we can only love what we know personally. And we cannot know much.”
—E.M. (Edward Morgan)
