and manufacturers must comply with the specific regulatory frameworks of each target market.


Europe


To sell radio equipment in the EU, designers and manufacturers must comply with the Radio Equipment Directive (RED) 2014/53/EU. This ensures devices are safe, do not interfere with other equipment, and use the radio spectrum efficiently. It should be noted that the requirements of the UK’s Radio Equipment Regulations 2017 are presently identical to the RED. RED Article 3.2 covers efficient use of the radio spectrum. This ensures that radio equipment uses the spectrum efficiently and avoids harmful interference. Compliance is typically demonstrated through the following harmonized standards:


EN 300 328 - For wideband transmission systems (e.g., Wi-Fi, Bluetooth)


EN 301 893 - For 5 GHz high-performance RLANs


EN 303 687 - For 6 GHz WAS/RLAN low power indoor devices and narrowband VLPs


Instrumentation Monthly October 2025


Wi-Fi 7 products operating in the 6 GHz band often require a Notified Body assessment under the RED due to EN 303 687 not being published in the Official Journal of the European Union.


United States


In the U.S., wireless devices must comply with the Federal Communications Commission (FCC) rules under Title 47 of the Code of Federal Regulations (CFR). These rules ensure devices operate within defined power limits and spectrum usage to prevent interference.


FCC Part 15.247 - Covers spread spectrum and digitally modulated devices in the 2.4 GHz band


FCC Part 15.407 - Applies to U-NII devices operating in the 5 GHz and 6 GHz bands.


Canada


Canada’s Innovation, Science and Economic Development (ISED) sets the standards for wireless devices to ensure safe and interference-free operation:


Item (19)-3 - Covers additional classifications, often related to low-power or short-range devices

RSS-247 - For devices operating in the 2.4 GHz and 5 GHz bands (similar to FCC Part 15.247 and 15.407)


RSS-248 - For RLAN devices operating in the 5925-7125 MHz bands.


Japan


Japan regulates radio devices under its Radio Law, enforced by the Ministry of Internal Affairs and Communications (MIC). Devices must be certified under Japan’s Technical Regulations Conformity Certification system to be legally marketed. Operation in the 5925-6425 MHz band was permitted in September 2022. Operation in the higher bands (6425-7125 MHz) is still under consideration. Key provisions include:


Article 2, Paragraph 1, Item (19) - Defines specific categories of radio equipment
