Bluetooth is a short-range wireless communication technology standard. Bluetooth uses short-wavelength UHF radio waves of a frequency range between 2.4 and 2.485 GHz.
What type of radio frequency transmission are used by Bluetooth?
However, the lower the frequency the lower the data rate it can support. As a result, selecting a radio spectrum comes with tradeoffs between range and data rate. Bluetooth® technology uses the 2.4 GHz ISM spectrum band (2400 to 2483.5 MHz), which enables a good balance between range and throughput.
What is Bluesnooping?
