What is bluetooth Easily explained
Whether on your smartphone, laptop or game console - you will find the "Bluetooth" option everywhere. In this article you will find out what exactly this is and where the radio standard is used.
Bluetooth - what is it?
Bluetooth is a radio standard that is built into a wide variety of digital devices and enables data transmission over short distances.
- The primary goal of the technology is to replace wired connections between devices. This is particularly beneficial for mobile devices.
- The maximum range varies between 10 and 100 meters depending on the device.
- Bluetooth has been developed and modernized for years. The latest version is Bluetooth 4.2 and is characterized by improved security, a high transmission rate and an energy-saving low energy mode. All versions are compatible with each other.
- With Bluetooth there are different profiles that determine what type of data can be transmitted. For example, the "HSP" profile enables a headset to be used via Bluetooth. With the "A2DP" profile, however, music can be transmitted wirelessly from a cell phone to a loudspeaker.
In which places is Bluetooth used?
Bluetooth is used in countless places. Here are some examples:
- Bluetooth is built into practically every modern cell phone. You can send files to other mobile phones or to your own computer.
- Many mobile speakers work via bluetooth. If you connect your smartphone to the speaker, you can transfer your music without any cables.
- It is not uncommon for cars to be equipped with Bluetooth technology. If your own mobile phone is in the car, it is automatically linked to the on-board computer so that incoming calls or messages can be displayed directly and answered using the hands-free system.
- Laptops also often have a Bluetooth chip. You can use this to wirelessly connect a mouse and keyboard, for example.
