'What is Bluetooth?': A beginner's guide to the wireless technology
Bluetoothis a wireless technology that allows the exchange of data between different devices.
- While Bluetooth uses wavelength to transmit information, it generally only works within a short distance for the devices to stay connected.

Now, as for the constant frequency changing? That's another part of the story entirely.
Bluetooth connections are secure wireless connections
Devices connected through Bluetooth are generally secure and safe against hacking.This is because they operate on any of various different frequencies, and the devices hop between these frequencies hundreds of times per second. It's called "frequency hopping spread spectrum," and it all but ensures that your Bluetooth devices can't be hacked – not by way of the Bluetooth signal, at any rate.
What Bluetooth is used for
As mentioned earlier, Bluetooth is often used to pair mobile devices with other mobile or fixed devices. This could be your earbuds, your car, and your smart fridge. But it is often also working in ways that are less immediately apparent, such as linking a printer or mouse to a computer.
Because Bluetooth and Wi-Fi are often complementary, working at the same time and offering much the same connectivity, you may not always know which hardware is pairing with which devices. Just know that if in range, devices previously paired via Bluetooth will try to automatically connect.
Because you often won't even realize when devices are connecting to one another via Bluetooth, it's a good idea to occasionally pop open your settings app on your phone (or any other device with Bluetooth connectivity), head to the Bluetooth tab, and take a look at all the devices that could potentially connect and note anything that is, in fact, already connected.
And if you ever get rid of a Bluetooth device or plan not to use it for a long time, by all means opt to "Forget this device" in your Settings app so you know you are maintaining control of the connection.
