Bluetooth is a low-power wireless technology that uses ultra-high frequency (UHF) radio waves for secure data exchange over short distances. Due to its energy efficiency, Bluetooth is a popular choice for connecting portable wireless devices like headphones, computer mice, and keyboards. Bluetooth connections have a range of up to 10 meters in the open.
A Bluetooth connection does not operate on a single frequency — rather, devices jump between frequencies hundreds of times per second, protecting them from hacking attempts through Bluetooth itself. This process is called “frequency hopping spread spectrum.”
