What is SACFA with respect to Radio frequency?

Specific Absorption Rate - Fixed Antenna (SAR-FA) is a specific type of Specific Absorption Rate (SAR) test that assesses the amount of radiofrequency (RF) energy absorbed by a human body when using a wireless device with a fixed antenna.

SAR is a measure of how much RF energy is absorbed by the body when using a wireless phone or other device that emits RF waves.

SAR tests include two types

- SAR - Head and Body: This test measures the power absorbed by user’s head and body for devices like Tablets and Smartphones.

- SAR - FA: This test measures the power absorbed by user’s body only for radio devices like wireless radio transmitters, laptop, etc.
