Bluetooth®Technology

Bluetooth

Bluetooth® is the established wireless communications technology for the short range, facilitating both voice and data transmission to create a personal area network. Bluetooth® is a spread-spectrum frequency-hopping system that works in the internationally available ISM bands at 2.4 GHz. Bluetooth® specification 2.0 implemented an enhanced data rate (EDR) of up to 3 Mbit/s. Bluetooth® also follows the trend toward lower power consumption. The Bluetooth® low energy technology has been adopted to achieve an ultra low power solution (Bluetooth® specification 4.0).

Bluetooth® is implemented in most mobile phones and laptops to enable wireless headset connectivity or connectivity between mobile phones and other devices for synchronization. Most new cars already offer a Bluetooth®-enabled hands-free calling system as standard or optional equipment. The very low power consumption of the Bluetooth® low energy technology addresses the market for sensors for sports, health and fitness, and also for watches. In addition, the ability to connect low power devices to mobile terminals make new applications possible.
