Protecting the User

Reducing Up to 95% of Near Field Intensity

EMR within one wavelength of the user is called Near Field Intensity (NFI). When you hold your cell phone to your ear, you are absorbing between 48 to 68% of the NFI radiated by your phone. It is this radiation that underlies increasing concerns among physicians, scientists, and lawmakers who believe this exposure to be a health hazard. The NFI of the iPhone 4/4S can be seen as a white "hot spot" in the picture below on the left. On the right, using Pong, NFI has been directed away from the user.

Due to the potential health risks associated with NFI radiation exposure, cell phone manufacturers always include with their instructions warnings to consumers on how to avoid exposure to NF radiation (see Cell Phone Makers instructions). This warning is necessary because the US government, and governments world-wide, use a measurement call Specific Absorption Rate (SAR) to measure and limit the amount of SAR each phone can produce. Unfortunately, very few consumers use their phones in the manner required by the manufacturers.

Without the Pong Device

SAR = 1.188 mW/g

With the Pong Device

SAR = .296 mW/g 75% Reduction

The above pictures are of actual laboratory results for SAR on an iPhone 4/4S. On the left, the near field energy emanating from the antenna is easily seen (SAR=1.188 mW/g) . Following application of a Pong device, the vast majority of the NFI has been diffracted away from the user (SAR=.296 mW/g). SAR is reduced by 75% in this example.

In the US, the SAR limit is 1.6 W/kg (watts/kilogram), averaged over a volume of 1 gram of tissue. In general, the lower the SAR, the better the chances your phone is not a potential health hazard. Federal Communications Commission (FCC) certified laboratories have consistently confirmed that Pong's patented technology reduces the amount of EMR absorbed into the user's head by up to 95%, as measured on the SAR scale.
