Bluetooth technology operates on a global scale using the 2.4 GHz ISM band, allowing devices to be used internationally without specific adaptations for local radio spectrum regulations. The Bluetooth Special Interest Group (SIG) ensures that all devices meet international standards for compatibility and interoperability.
However, there are certain regulatory considerations that vary by country. Some nations require Bluetooth devices to undergo type approval, for example CE (for Europe) or FCC (for USA), to ensure they adhere to local standards. Additionally, power output limitations for Bluetooth devices can differ from one country to another. For example, Australia permits a maximum of 200 mW e.i.r.p. within a specific frequency range, while most European countries adhere to standard ISM band regulations.
