Radio Standards Specification, RSS-102.SAR.MEAS, Issue 2 and RSS-102.SAR.SIM, Issue 1

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.
