Specific Absorption Rate (SAR) Testing
SAR limits are there to protect all of us from wireless devices that exceed the transmit Radio Frequency (RF) threshold. SAR stands for Specific Absorption Rate. It's a measure of the rate at which energy is absorbed by your body when you are exposed to an RF electromagnetic field. In some countries, the SAR test result figure has to be displayed at the point of sale. To have a presence in these markets, your products must meet strict SAR regulations.
