Bluetooth hotspots enable wireless access to the Internet or a corporate LAN. Audio devices without Bluetooth, especially older mobile phones and landline phones can be restricted via a connected Bluetooth adapter. Specifically for intercoms, in recent years, many manufacturers increasingly used Bluetooth, with ranges up to 1.6 km. Particular advantages are very small sizes and the absence of annoying cables.
Due to the adaptive frequency hopping used (AFH), Bluetooth provides a very reliable and interference-resistant radio link as part of Network System Management. This advantage of Bluetooth over other wireless technologies was recognized early on by various manufacturers of automation products. Then Bluetooth-based industrial products were implemented, which are used in various fields of industry in order to wirelessly communicate between different components in machines.
In orthopedics, Bluetooth is used to set modern arm and leg prostheses. Settings such as phase damping and maximum load can be made via Bluetooth.
