What is SAR in Mobile?

The abbreviation “SAR” stands for Specific Absorption Rate. A radio-frequency (RF) electromagnetic field, such as the one emitted by a cell phone, can cause the human body to absorb electromagnetic radiation at a rate known as SAR.

In order to connect to cell towers and other wireless devices, mobile phones and other devices also produce radio waves. Some of this RF energy is absorbed by your body when you use a mobile phone, particularly in locations near the antenna. SAR, which is usually expressed in watts per kilogramme (W/kg), is a measure of how much RF energy is absorbed by each unit of body tissue.

SAR limitations have been set by regulatory bodies in many nations to guarantee the safety of mobile phones and other wireless devices. These restrictions are made to shield users from RF energy exposure that might be harmful to their health.

The SAR value of a mobile phone is typically included in the product specifications when you buy it. You can use this data to assess the possible RF exposure of various devices, however it’s crucial to keep in mind that different phones may have varying SAR values. A phone with a lower SAR value emits less RF energy and is typically thought to be safer in terms of RF exposure.

To reduce your exposure to RF energy, keep the phone away from your body when not in use, and, whenever possible, shortening phone calls.
