The new RSS is the official update to the measurement procedures for assessing the compliance of radiocommunication devices with respect to specific absorption rate (SAR) under Canadian standard.

This new version replaces the 2023 version and introduces significant changes, including additional requirements for the use of time-averaged SAR (TAS) algorithms in multiple technologies (WWANs, WLANs, NTNs, and Bluetooth), procedures for time-averaged absorbed power density (TA-APD) for devices operating in the 6 GHz band, test methods for foldable or protruding equipment, as well as guidelines for accessories, motion sensors, and the validation of multiple TAS applications.

The standard covers all equipment operating in the 100 kHz to 6 GHz range, where the primary compliance parameter is SAR. For higher frequencies (6 GHz to 7.125 GHz) absorbed power density (APD) is used, and in cases where a channel crosses 6 GHz, both parameters must be evaluated.

WHOM DOES IT IMPACT?

The direct impact is on wireless device manufacturers, certification laboratories, and regulatory authorities.

CONCLUSION:

The new RSS represents a high-impact regulatory change that modernizes RF radiation safety criteria.
