SAR in Mobile phones and SAR Value of major phones


SAR stands for Specific Absorption Rate, which is the unit of measurement for the amount of RF energy absorbed by the body when using a mobile phone. The SAR is determined at the highest certified power level in laboratory conditions. However, the actual SAR level of the phone while operating can be well below this value. This is because the phone is designed to use the minimum power required to reach the network. Therefore, the closer you are to a base station, the more likely it is that the actual SAR level will be lower.

Specific absorption rate (SAR) is a measure of the maximum rate at which radio frequency (RF) energy is absorbed by the body when exposed to radio-frequency electromagnetic field. It is used for exposure to fields between 100kHz and 10 GHz. The SAR value will depend heavily on the geometry of the part of the body that is exposed to the RF energy, and on the exact location and geometry of the source of the RF energy. Thus tests must be made with each specific source, such as a mobile phone model, and at the intended position of use. The value cited for a specific model is then the maximum level measured in the body part studied. The most common use is in relation to mobile phones, and here the mobile phone is placed at the head in a talk position. The SAR value measured is then value measured in the place that has the highest absorption rate in the entire head, which for a mobile phone often is as close to the phone as possible. Various governments have defined safety limits for exposure to RF energy produced by mobile devices that mainly exposes the head or a limb for the RF energy
