Default Blackberry power level 4.9GHz

Now all you need to prove, is that the RF Power Density of a 300
Milliwatt Cellphone, operating one one of 4 Bands in the 800-900
Mhz, and 1800 - 2000 Mhz, will cause ANY Measurable Heating in
Human Tissue, and therefore cause some sort of problem. So far,
NOBODY has shown that to be the case. Not even in the 2.4 Ghz
ISM Band where BlueTooth operates, with significantly LESS
Power Density. There are enough of these devices around that
should all this "Wild Speculation", actually have Observable Effects,
the researchers into this area wouldn't be needing to do Statistical
Analysis, to Magically try and prove some nebulous Causal Effect.

====================================
It might be useful to know that the RF power radiated by any cellphone
is dependent on the distance between the device and the nearest base
station.
In a built-up area or along the highway with nearby base stations the
power can be very low ,whereas at remote locations it can be as high as
2 Watts (at least here in Europe).
Living away countryside ,when using my cellphone at home the battery
drains rather quickly compared when using the device in town.
When holding the cellphone near my HF transceiver I clearly hear the
digi-noise.
For this reason I avoid using the cellphone while at home or at other
locations away from a base station.
My home is approx 8 km (5miles) from the nearest base station.
