(Or said tongue-in-cheek ?) Seriously, your should never take anything I suggest seriously. I lied. It's more like 10 microwatts, not 1 milliwatt if it meets FCC part 19 incidental radiator, and about 100 times worse after some mechanical case or shield damage. Let's do the math and see how badly I screwed up. LO radiation is typically about -60dBm at the antenna. If there are multiple leaks, it might climb to maybe -50dBm. -50 dbm = 0.00001 milliwatts = 10 microwatts = 1*10^-8 watts 50,000 such cell phones would belch: 5*10^4 * 1*10^-8 = 5*10-4 watts = 50 milliwatts (not 50 watts). If each cell phone radiated 1 mw, then we might have a problem. In addition, the LO is not always powered on in a cell phone, where the battery save algorithm only turns it on during the proper time slot. Exposure would have to be reduced by the duty cycle. Extra credit for estimating the total LO radiation for the continental USA. Figure on about 100-500 billion devices. Perhaps we should try calculating how much 2.4GHz energy is delivered when we're out in the noon day sun to see if a tin foil hat is required. Total energy is about 1000 watts per square meter, mostly in the visible light region. Still, there's plenty of power in the microwave region. I'll do the math when I return from from lunch and a bike bicycle. -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
