Let's say just those figures are correct ... My Motorola Razar V3 phone is approx. 6mm thick (when opened), and where the antenna is buried in the phone. This means the antenna can be no more than 6mm from my head if the phone lies against my head. Now, we assume the phone is emitting 300mw. This would be equivalent to 1.2w of power emanating from that same antenna at a distance of 12mm from my head. And, the latter would be equivalent to 4.8w emanating from the same antenna at a distance of 24mm from my head. And, the last would be equivalent to 19.2w emanating from the same antenna at a distance of 48mm from my head ... your higher figure, of two watts, is simply frightening ... The lunacy is exposed ... correct any error you see in the above ... Regards, JS Sonny, you seem to be using the Inverse, of the Inverse Square Law here.... the Farther the source is from the receiver the LESS power reaches the receiver, not MORE. It goes Down, by the SQUARE of the distance, not up. You also don't get ALL of the 300 Milliwatts going into your head as the antenna is semi Omni-directional and only about 120 degrees of the 360 degree transmitted signal will intersect with your head, and another maybe 10 degrees with you hand. Better go back and do the Sums, AGAIN, or leave it to folks that passed Jr. High School Math, and High School Physics. |
