What is SAR?

Electronic and wireless devices have become an integral part of modern life. As the use of wireless devices rapidly expands, a concern of possible radiation damage to the human body due to prolonged exposure to electromagnetic (EM) radiation raises. Despite EM being a non-ionizing radiation, many studies show an Inconclusive link between EM radiation and any human body damages. Therefore all cell phones are now required to meet the "Specific Absorption Rate" standard or SAR for short.

Specific Absorption Rate is defined as the unit of measurement for the amount of radio frequency EM field absorbed by the human body when using a wireless device. The SAR value is expressed in terms of watts per kilogram (W/kg) or milliwatts per gram (mW/g).

SAR world-wide limits for example:
  • The FCC and Industry Canada limit for public exposure is a SAR level of 1.6 watts per kilogram (1.6 W/kg).
  • The European Union and many other countries have a SAR limit of 2.0 watts per kilogram (2 W/kg).
