The Department of Innovation, Science and Economic Development Canada is seeking comments on the following consultations:
- RSS-102-SAR.MEAS, issue 2, “Measurement Procedure for Assessing Specific Absorption Rate (SAR) Compliance in Accordance with RSS-102”.
- RSS-102.SAR.SIM, issue 1, “Simulation Procedure for Assessing Specific Absorption Rate (SAR) Compliance in Accordance with RSS-102”.
Both documents are part of the RSS-102 series of standards which set out the requirements, measurement and simulation techniques to be employed for evaluating RF exposure compliance of radiocommunication apparatus (Category I and Category II equipment) that are designed to be used within the vicinity of the human body. This standard applies to:
- radiocommunication apparatus having an integral antenna,
- systems requiring licensing with detachable antennas offered with the transmitters, or
- licence-exempt transmitters with detachable antennas, as defined in RSS-Gen.
The requirements within RSS-102 also apply to wireless power transfer (WPT) source subassemblies, including Type 1, which are classified as interference-causing equipment.
Within RSS-102.SAR.MEAS, issue 2, the following key changes are being proposed:
- New requirements and clarifications for time-averaged SAR (TAS) for algorithm approvals and final product implementations including wireless wide area networks (WWANs), wireless local area networks (WLANs), and non-terrestrial networks (NTN);
- New requirements on time-averaged absorbed power density (TA-APD) for WLAN devices operating in the 5925-7125 MHz;
- New requirement for TAS measurements allowed to be conducted with an array class 2 fast SAR system as per IEC/IEEE 62209-1528; and
- Clarified test procedure for foldable devices.
Within RSS-102.SAR.SIM, issue 1, the content is nearly identical to SPR-002 issue 2, with the following exceptions:
- The requirements for SAR measurements are located in RSS-102.SAR.MEAS, issue 1;
- The requirements for nerve stimulation (NS)-related measurements are located in RSS-102.NS.MEAS, issue 1;
- The requirements for NS-related simulations are located in RSS-102.NS.SIM, issue 1
- The frequency range is extended from 100 kHz to 6 GHz and the dielectric properties are adjusted, accordingly;
- The SAM phantom is introduced; and
- The requirements for calculation of the uncertainty are clarified.
Comments are due no later than March 31, 2025.
