Specific Absorption Rate (SAR) is the rate at which electromagnetic power radiated from mobile handsets and towers is absorbed by the human body. 2. What is a SAR value? SAR Value is a measure of the maximum energy absorbed by a unit of mass of exposed tissue of a person using a mobile phone, over a given time or more simply the power absorbed per unit mass . Basic of Cell Phone Network Connectivity Before we start our discussion about SAR value and its significance, we need to first understand some concepts of network connectivity, such as antenna and signal. Specific Absorption Rate (SAR) is a measure of the amount of RF power deposited in the human head or body whenever a mobile phone or other wireless radio device transmits. It is the maximum SAR value (in units of Watts/kilogram) that is measured during SAR compliance testing. All mobile phone models are tested to make sure they meet national. Even though gradient-echo techniques apply radiofrequency pulses very rapidly, the net deposition of power is lower, resulting in lower SAR and less tissue heating. However, certain gradient-echo sequences, e.g., time-of-flight MR angiography, apply radiofrequency pulses at such a high speed that they also result in high SAR
