Bluetooth is a wireless communication standard that allows data exchange between electronic devices via short-range radio waves. This technology is widely used for data transmission between mobile devices such as smartphones, tablets, and wireless earbuds, and for connecting peripherals such as keyboards, mice, printers, and speakers to computers and other devices. Bluetooth operates on a 2.4 GHz frequency band and provides a secure and reliable communication interface.
In everyday life, Bluetooth manifests in a wide range of practical applications. For instance, users can connect their smartphones to their car's audio system via Bluetooth to stream music or make hands-free calls. Wireless headphones use Bluetooth to play audio wirelessly from devices like smartphones or music players. Additionally, Bluetooth is used for file transfer between devices, data synchronization between mobile devices and computers, and remote control of smart home devices.
In Switzerland, Bluetooth is widely used at both personal and commercial levels. For example, in Swiss cities, public transport systems offer contactless payment options via Bluetooth, allowing users to pay for their tickets simply by bringing their smartphone or credit card close to the payment terminal. Moreover, Bluetooth is also used in industrial and medical applications, such as health monitoring devices and tracking and locating devices within hospitals, without requiring the installation of a data SIM. Due to its versatility and security, Bluetooth continues to play an important role in Switzerland's digital ecosystem.
