Standards Update for Bluetooth/Zigbee/WLAN Radios

There’s a new v2.2.2 revision of ETSI EN 300 328 – the 2.4GHz radio standard for Bluetooth, Zigbee and WLAN/Wi-Fi.

The main difference appears to be an increase in the Receiver Blocking requirements in 4.3.1.12. Blocking signal power increases from -53dBm to -34dBm.

Transition starts on 6th August 2020. The V2.1.1 standard ceases to give a Presumption of Conformity on 6th August 2021.

What does this mean for your products?

If you use a CE marked Radio module in your product then get onto your manufacturer and ask what their plans are to demonstrate compliance to this requirement.

If you have your own radio solution on board then you should investigate additional testing to determine if you are compliant or not. Unit 3 Compliance can assist with testing if required, get in touch to see how we can help.

You’ll also need to update your Technical Documentation with details of the new standard.
