Summary

The SIG's guide to how 2.4 GHz radio rules in the EU and UK, the US and Canada, China, Japan and Korea apply to Bluetooth LE products, including LE Audio broadcasts.

Key findings

  • Under the European standard EN 300 328, a device transmitting at +10 dBm EIRP or more must either meet the standard's adaptivity requirements (detect-and-avoid or listen-before-talk) or accept medium-utilisation limits with enforced gaps between transmissions.
  • The channel selection in the Bluetooth Core Specification does not by itself meet those adaptivity requirements, so meeting them is left to each product. For wideband (non-hopping) equipment, the document names staying below +10 dBm as the simplest way to avoid the limits.
  • Equipment assessed as wideband is also limited by power density to slightly above +10 dBm EIRP on the LE 1M radio mode and slightly above +13 dBm on LE 2M.
  • When checking duty-cycle limits, the airtime of all broadcast streams and of the advertising that announces them must be added together.

Limits

Informational; it states that it does not replace the regulations, which have changed since 2023. It explains the rules and does not report what any product does.
