Bluetooth

Bluetooth is an internationally recognized industrial standard that complies with IEEE 802.15.1 and enables wireless, cross-system data transmission. This technology uses the frequency hopping method with 79 channels and a bandwidth of 1 MHz in the frequency range from 2.4 to 2.4835 GHz, enabling transmission rates of up to 2.2 Mbit/s (using the EDR method) to be achieved.

The special feature of Bluetooth is the possibility of assigning up to seven slave devices to a master device, whereby these must share the available bandwidth, depending on the number of slaves. This flexibility enables a wide range of applications and networking of different devices.

The name “Bluetooth” goes back to Harald Bluetooth, a king of the Danes in the 10th century. He was known for using flags to transmit messages from ship to ship. The link to the modern Bluetooth standard lies in its ability to enable wireless communication and networking between different devices, similar to the way Harald Bluetooth facilitated communication between ships.

Bluetooth has become an indispensable part of everyday life and is used in a variety of applications, including wireless headphones, speakers, smartphones, wearables, and much more. The ongoing development of this technology promises an even wider range of applications and a continuous improvement in performance.
