re: SAR << IF there are biological effects from cellular phones, CDMA phones are the least harmful. >> IF ... that is entirely dependent on their SAR. Not all CDMA phones are created equal in that respect. IF (again) a CDMA phone has a higher SAR than the GSM model and a TDMA model then (potentially) that CDMA phone is the most harmful. - Eric -

Paul, 100 milliwatts at the peak in GSM isn't very much energy. Brains run at around 20 watts and they have arterial pulses which are noisy. Since I guess only about 10% of the energy from a GSM phone would be absorbed, that's only 10 milliwatts to thermoelastically knock our brains around. hypertextbook.com Smart brains don't do much - scans show little activity when solving problems which are solved quickly with good answers. Dull brains thrash around with all parts lighting up - finally, a bad idea comes out. Deep Blue goes really fast to solve problems whereas lazy Kasparov lights up a few neurons and calls it done. Deep Blue shows that genius is 90% perspiration and 10% inspiration - Deep Blue cleans Kasparov up, no sweat. 20 watts normally versus 0.01 watts absorbed = 1/2000th of the energy. So we can see that brains do NOT get warmer due to cellphones, even if they were run all day every day, because brains have cooling. Thinking for a few minutes would generate more heating than a cellphone and nobody suggests thinking is a bad thing to do, other than the Taleban and other authoritarian people who prefer to run our lives for us - also the Attention Deficit Hyperactive Disorder impulsivity fan club members [ADDH, to be quick about it] who say "Just Do It". Also the thermoelastic pulse from 0.01 watts switching on and off would be undetectable compared with the normal arterial and other pulsing going on in a brain. Isn't that comment from IEEE related to walking in front a radar antenna or perhaps from electromagnetic pulse from a nuclear explosion, where energy absorption is indeed enough to make a brain shake or at least get warm? Anyway, as you and engineer say, if there are any effects from cellphones, CDMA phones are the ones to use. I don't believe anyone can hear a cellphone [via thermoelastic pulse due to brain heating]. That should be really, really easy to test. There wouldn't even be a need to do large studies. Just get twenty 17 year old women [whose ears are still really good and who can hear 20 kilohertz sfu.ca ] Take the speakers out of the phones. Then phone them and see if they can push a button when their phone starts running. Mq PS: Do you have links to graphs of CDMA emissions out of band which would show guard band effects in the 800 - 900 MHz range [when adjacent to analogue and GSM]. I'm trying to figure out whether 2 x 1.25 MHz CDMA channels would fit into 4 MHz between 890 and 894 MHz with analogue below and GSM above. If the analogue was converted to CDMA, maybe 3 x 1.25 channels could squeeze in?
