As noted above, Bluetooth works in the 2.4GHz frequency range and sends 79 different bands of radio waves inside this frequency. As data is sent, Bluetooth divides all of your data into smaller, more transferable packets. Once the packets have been divided, they are then sent individually over those 79 bands, all while being smart enough to not get clogged up anywhere. Of course, all of this happens within microseconds with almost no lag between the two connected devices
Bluetooth Versus Wi-Fi
Unlike your Wi-Fi or 3G/4G/5G connections, Bluetooth doesn’t use any data. That’s good news for people in today’s world who connect their smartphones to their cars and stream music. While the actual streaming of music uses data, connecting to your car via Bluetooth uses no Internet data and has minimal impact on battery life.
