The Department of Innovation, Science and Economic Development (ISED) Canada is inviting public comments on updates to two key documents in the RSS-102 series related to radiofrequency (RF) exposure compliance. These updates impact radiocommunication devices near the human body, covering measurement and simulation procedures for Specific Absorption Rate (SAR) compliance. Stakeholders have until March 31, 2025, to share their feedback.
What Are RSS-102 Standards?
The RSS-102 standards outline the RF exposure compliance requirements for devices such as:
- Radiocommunication apparatus with integral antennas.
- Systems requiring licensing that use detachable antennas.
- Licence-exempt transmitters with detachable antennas (as defined in RSS-Gen).
These standards also apply to wireless power transfer (WPT) subassemblies that may cause interference.
By ensuring devices meet these standards, ISED helps protect users from excessive RF exposure and maintains compliance with safety regulations.
Key Updates in RSS-102.SAR.MEAS, Issue 2
The updated RSS-102.SAR.MEAS document proposes significant changes, including:
1. Time-Averaged SAR (TAS) Requirements
New guidelines clarify TAS compliance for:
- Wireless Wide Area Networks (WWANs).
- Wireless Local Area Networks (WLANs).
- Non-Terrestrial Networks (NTNs).
2. Time-Averaged Absorbed Power Density (TA-APD)
Devices operating within 5925-7125 MHz must now meet TA-APD requirements to ensure safe levels of RF exposure.
3. Faster SAR Measurements
The new draft allows the use of array class 2 fast SAR systems for TAS measurements, following IEC/IEEE 62209-1528 standards.
4. Foldable Device Testing
Clear testing procedures have been introduced for foldable devices, reflecting advancements in device designs.
Introducing RSS-102.SAR.SIM, Issue 1
RSS-102.SAR.SIM builds on existing simulation guidelines, with updates tailored to modern technologies. Key points include:
- Relocation of SAR Measurement Requirements: These are now included in RSS-102.SAR.MEAS, Issue 1.
- Extended Frequency Range: The range now covers 100 kHz to 6 GHz, with adjustments to dielectric properties.
- SAM Phantom Inclusion: The updated simulation procedure incorporates the Specific Anthropomorphic Mannequin (SAM) phantom for more accurate results.
- Uncertainty Calculations: Guidance on calculating uncertainties has been clarified for greater precision.
Why These Updates Matter
These proposed changes reflect ISED Canada’s commitment to:
- Keeping pace with advancements in wireless technologies.
- Ensuring user safety with more comprehensive RF exposure evaluations.
- Providing clear testing and simulation procedures for innovative devices.
Manufacturers, engineers, and industry stakeholders should review these updates to ensure compliance and address potential challenges early.
