With that research that just came out from Sweden about cell phone use and brain tumors, I have a question that is related. If you carry the phone in your pocket but aren't actually using it, can this cause any problems? I'm asking when the phone is turned on, does the RF or whatever still go to the phone or do you actually have to be using the phone? The reason I ask is because I always carry the phone in my pocket and I keep it turned on, so I want to know if there are any adverse effects.
In order to get incoming calls, the system has to know what cell you're in. The MTSO (Mobile Telephone Switching Office) keeps track of which phones are in which cells by every now and then sending them "Where are you, how ya doin'? " on the control channels. The phones respond with info regarding what signal strength they're getting from which cell sites. So, yes, there is RF communication going on -- though just a little bit -- all the time. Look at the amount of talk time you get on a battery, and the amount of standby time. The power used in each mode is inversely proportional to the amount of time you can operate at that load on a charge. The phones also use different transmission power levels depending on how well they're getting thru to the sites. If the signal they get is strong, they know to use the low level, 0.6 Watt, to respond. If it's weak, they know to use the high level, 3.0 Watts, to respond. So, the more bars, the better for RF exposure. These researchers never seem to test it, but I'm sure that the traditional tin foil hat would help a lot. ;-) -- J.S.

Also since 800-850 MHZ penetrates buildings better would that also mean it would have more of an adverse effect on your health than 1900 MHZ?
The thing to remember here is that all these reports of tumors will say "studies show......blah blah" but in ALL the reports I have seen, they always say, "more studies need to be done". If that is the case, then why release the report in the first place when the research is obviouisly not complete. As it stands right now from what I can tell is that the overall results are inconclusive and that is evident by specialists arguing about it all the time. So I would take these reports with a big grain of salt and get on with my day to day life.
The polluted air that that we breath everyday probably has more negative effects than any RF exposure.
Low power, non-ionizing radio waves do not cause cancer or tumors. We can do studies until kingdom-come, but it will still be impossible to absolutely prove a negative assertion. For example, try to prove that bigfoot doesn't exist.
