There have been a lot of news stories recently about the long-term dangers of cell phone usage. What is the impact of holding a cell phone against your head? While the jury is still out on the long-term effects of cell phone usage, you can use the Specific Absorption Rate (SAR) of a cell phone to determine what's getting reflected back to your head.
Since the VisorPhone was just released, I wanted to find out what its SAR was.
According to the FCC, the highest reported SAR value for the head is 0.48 W/kg.
If you Wear the VisorPhone, the SAR on the body is 0.22 W/kg. These numbers are based on PCS-1900 MHz usage and will be different for international GSM frequencies.
So are those numbers good? The maximum SAR that the FCC allows is 1.6 W/kg, so the VisorPhone does a pretty good job of shielding the user.
