More Information about Bluetooth

Bluetooth named after a Viking

The technology was developed to avoid the need for additional cables with which you can establish the connection between two devices. In fact, the origin of the name goes back to the Viking king Harald Blauzahn. Blauzahn, or Bluetooth, united Norway with Denmark in the 10th century. In reference to this connection, the name therefore represents a symbol for networking.

Besides the wireless connection, the advantages of the technology are its wide availability and low energy usage due to its low power consumption. Disadvantages are the limited range and – compared to other technologies – the lower transmission speed. On top of that, connections via Bluetooth are quite error prone. Especially in urban areas, transmission problems can occur.

Today, there are numerous revisions on the market. We have listed the differences in a chart to give you a better overview. The maximum possible range applies to open areas and can be significantly lower in buildings.
