SAR Testing Solutions
SAR, also known as Specific Absorption Rate, refers to the electromagnetic waves absorbed or consumed per unit mass of human tissue. The unit is W/Kg or mw/g. It refers to the measured energy absorption rate of the human body when exposed to radio frequency electromagnetic fields.
SAR testing is mainly aimed at wireless products with antennas within a distance of 20cm from the human body. It is used to protect us from wireless devices that exceed the RF transmission value. Not all wireless transmission antennas within a distance of 20cm from the human body require SAR testing. Each country has another testing method called MPE evaluation, based on products that meet the above conditions but have lower power.
