On August 3, 2023, Innovation, Science and Economic Development Canada (ISED) published RSS-247 Issue 3, Digital Transmission Systems (DTS), Frequency Hopping Systems (FHS) and License-Free Local Area Network (LE-LAN) Devices, which replaces RSS-247 Issue 2. The main changes are as follows:

• Section 2.1 has been added to include information about the entry into force of the standard;
• Section 6.2 has been modified to clarify that different measurement methods can be applied depending on the operating frequency range of the device;
• Added section 6.2.5 on the requirements for devices operating at 5850-5895 MHz and channels with frequency ranges spanning 5850 MHz
• Section 6.2.5.1 has been added to provide general information and definitions;
• Section 6.2.5.2 has been added to determine the power limits of devices operating in the 5850-5895 MHz band;
• Section 6.2.5.3 has been added to determine the unwanted emission limits for devices operating in the 5850-5895 MHz band;
• Other editorial changes and revisions made to improve clarity.

With this standard update, ISED still provides a six-month transition period, and manufacturers can choose to test in either Issue 2 or Issue 3 until February 3, 2024.
