Radio Standards Specification RSS-248, issue 3, governs the certification of licence-exempt Radio Local Area Network (RLAN) devices operating within the 5925-7125 MHz frequency band. This new version replaces RSS-248, issue 2, which was released on December 20, 2022. The updated standard incorporates several important changes to address emerging technologies and usage within this frequency range.
The certification requirements for Radio Local Area Network (RLAN) devices operating in the 5925-7125 MHz band can vary by country, but they generally follow similar principles, especially in regions that align with the International Telecommunication Union (ITU) guidelines.
Here’s a general overview of the certification requirements typically involved:
1. Regulatory Authority Compliance
- FCC (USA): In the United States, RLAN devices must comply with the Federal Communications Commission (FCC) regulations. Devices operating in the 5925-7125 MHz band may need to adhere to Part 15 (unlicensed) or Part 90 (licensed) rules, depending on their intended use.
- European Telecommunications Standards Institute (ETSI): In Europe, devices must comply with ETSI standards and the EU’s Radio Equipment Directive (RED).
- Other Regions: Countries may have their own regulatory bodies (e.g., ACMA in Australia, OFCOM in the UK) with specific requirements.
2. Technical Standards
- Standards Compliance: Devices may need to meet specific technical standards, such as IEEE 802.11ax (Wi-Fi 6) or other relevant protocols.
- Spectrum Management: Compliance with dynamic frequency selection (DFS) requirements to avoid interference with incumbent users in the band, especially radar systems.
3. Testing and Certification
- Testing Laboratories: Devices typically need to be tested in accredited laboratories to demonstrate compliance with relevant technical standards.
- Certification Process: After testing, manufacturers must submit documentation to the relevant regulatory authority or certification body for approval.
- Labeling: Certified devices may need to display specific labels indicating compliance (e.g., FCC ID, CE mark).
4. Operational Restrictions
- Power Limits: There are often limits on transmission power levels to minimize interference with other services.
- Channel Usage: Restrictions on the channels that can be used in the band and the need to implement listen-before-talk (LBT) mechanisms in some cases.
5. Post-Certification Requirements
- Ongoing Compliance: Manufacturers may need to conduct periodic testing to ensure continued compliance with regulatory standards.
- Changes to Device: Any modifications to the device design may require re-evaluation and re-certification.
Main Updates in RSS-248, Issue 3:
- New Equipment Class Added:
A new equipment class for very low-power devices has been introduced, catering to low-energy-consumption applications. - Definitions, Power Limits, and Operational Requirements:
Definitions and specific power limits for very low-power devices have been added, along with operational requirements that ensure compliant performance within the 5925-7125 MHz band. - Editorial Clarifications:
Several editorial changes and clarifications have been made to improve the clarity of the standard’s provisions.
These updates are essential for manufacturers and stakeholders involved in the certification of RLAN devices, ensuring that devices meet current regulatory requirements for safety, efficiency, and performance in the 5925-7125 MHz band.
Manufacturers of RLAN devices operating in the 5925-7125 MHz band should consult their local regulatory authorities for specific requirements and guidelines. Staying informed about changes in regulations and technological standards is also crucial for compliance and market readiness.
