The specific absorption rate (SAR) is the rate at which radio frequency energy — a type of electromagnetic radiation — is absorbed by a biological body. SAR is expressed in watts per kilogram (W/kg). Industry Canada requires that all cell phones and other mobile devices sold in Canada comply with certain regulatory SAR limits.
TELUS does not test the SAR values of the devices we sell. Rather, we rely on the SAR values provided by manufacturers, Industry Canada and the US Federal Communications Commission (FCC).
