Bluetooth operates within the 2.4 GHz frequency band.
The Bluetooth® technology website confirms that Bluetooth utilizes the 2.4 GHz ISM (Industrial, Scientific, and Medical) spectrum band, specifically ranging from 2400 to 2483.5 MHz. This frequency band is crucial for Bluetooth's functionality, providing a balance between communication range and data throughput.
Here's a breakdown of why this is important:
- Frequency Band: The 2.4 GHz band is a globally recognized and license-free band, making it suitable for widespread use.
- ISM Band: As an ISM band, it can be used for various applications, including Bluetooth, Wi-Fi, and microwave ovens. This common usage also means that devices need to be designed to mitigate potential interference.
- Range and Throughput: The 2.4 GHz frequency offers a good compromise, providing a reasonable communication range for many devices while maintaining sufficient data transfer speeds.
The use of this particular frequency band allows Bluetooth to maintain its relatively low power consumption while still allowing for effective communication between devices over short distances.
