RSS-247 Digital Transmission Systems, Frequency Hopping Systems and License-Exempt LAN Devices Updated to Issue 4

On July 24, the ISED updated RSS-247 Digital Transmission Systems, Frequency Hopping Systems and License-Exempt Local Area Network Devices in 902-928 MHz, 2400-2483.5 MHz, 5150-5350 MHz, and 5470-5895 MHz bands to issue 4. This issue has come into force as of the date of its publication, but a transition period of six months from the publication date has been provided. During this period, applications for certification under issue 3 or issue 4 will be accepted. From January 24, 2026, only applications for certification under issue 4 will be accepted. The main changes are as follows:

⚫ Removed the restriction on the operation of devices in the 5,600-5,650 MHz frequency range.

⚫ Modified section 6.4 related to hybrid devices to introduce requirements distinguishing hybrid devices from a mere combination of FHS and DTS devices.

⚫ Removed the directional antenna/antenna array calculation since the directional gain calculation is covered in the normative reference ANSI C63.10 and the measurement procedure in the accepted KDBs.

⚫ Added clarification for LE-LANs operating within vehicles in the bands 5,150-5,250 MHz and 5,250-5,350 MHz.

⚫ Modified point b) in section 7.3.1.3 related to the unwanted emissions of transmitters operating in the 5,150-5,250 MHz to clarify the requirement.

⚫ Added a reporting requirement to section 7.1 for devices implementing transmitter power control.

⚫ Modified the transmit power control requirement in sections 7.3.1.2 and 7.3.2.2.

⚫ Modified section 7.3.2.1 to introduce the indoor labeling requirement for the unwanted emissions.

⚫ Modified section 7.3.2.3 to clearly identify the different unwanted emission limits of transmitters operating in the band 5,250-5,350 MHz.

⚫ Modified section 7.3.6.1 to specify that only the ETSI EN 301 893 test procedure shall be used to demonstrate DFS compliance in the 5,600-5,650 MHz band.

⚫ Made various editorial changes throughout the document.
