Actually the SAR is a very confusing benchmark. The procedure of measuring SAR is tricky too. For example, if a mobile phone has its antenna located at the bottom of the phone away from the user's face, the resultant SAR value will be a lot lower. In comparison, if the antenna of the mobile phone is located on the top of the phone just below the mobile phone speaker, the SAR value will be higher.
Now the transmitting power from the phone must be high enough so that you get good reception and audio quality. Otherwise your phone will keep on searching for telco and end up using more battery power to stay connected to the telco base station. So most manufacturers will try to strike a balance between transmitting power, battery consumption and SAR value. They'll try to locate the best position to fit in the antenna without increasing SAR value too much.
We now have 50 years worth of history using wireless phones and so far we don't have a string of people dying of cancer yet. So I'm not concern. However, having said that we should practice good rationalism when it comes to these issues. Like reducing usage of mobile phone because they help us save money more than our health
If SAR value of mobile phone is destructive, wait till you see gadget freaks sticking their bluetooth handsfree on their ears! Hahaha!
2.4GHz electromagnetic waves pounding to and fro their handsets next to their genitals. Wait till you see that SAR value. Also, what about people living below those base stations? What about people living close to high-tension electrical cables that also emits powerful electromagnetic waves? What about the car that you drive? The spark plugs emits high powered waves too. Your iPods, in-house WIFI with those high gain antennas, radio sets, and walking around the street where our air is filled with noisy communication wireless link?
Your view on SAR value scares the hell out of me. LOL Now the transmitting power from the phone must be high enough so that you get good reception and audio quality.
