Which type of waves are utilized for Bluetooth transmissions?

Bluetooth technology utilizes low powered radio waves for its transmissions. This particular type of radio wave operates in the 2.4 GHz ISM (Industrial, Scientific, and Medical) band, which is a globally available frequency band. The use of low powered radio waves is integral to Bluetooth's design, allowing devices to communicate with each other over short distances—typically within a range of about 10 meters (30 feet). This low-power requirement also means that Bluetooth is energy-efficient, enabling devices, such as smartphones and wireless peripherals, to conserve battery life while maintaining constant connectivity.

The characteristics of low powered radio waves also contribute to Bluetooth’s ability to support various applications, from simple data transfer to more complex operations like audio streaming. The design prioritizes minimizing interference with other devices operating in the same frequency range while providing a reliable connection.

In contrast, other types of waves, such as ultrasound, infrared, or high frequency radio waves, do not align with the transmission mechanisms and required performance parameters of Bluetooth technology.
