Unveiling the Fascinating Origins and Cutting-Edge Evolution of Bluetooth Technology
Bluetooth technology is a wireless communication standard that enables short-range data transfer between Bluetooth-enabled electronic devices. It was first introduced in 1994 by Ericsson, and since then, it has become an integral part of numerous consumer electronics and industrial applications. Bluetooth operates in the 2.4 GHz frequency band and uses radio waves to establish connections between devices.
The current Bluetooth standard, introduced in December 2016, is Bluetooth 5.0. Bluetooth 5.0 was updated in December 2019 with the releases of versions 5.1 and 5.2.
Bluetooth 5.1 introduced a significant feature called Direction-Finding, which enables more precise location tracking in telematics devices. This feature utilizes Angle of Arrival (AoA) and Angle of Departure (AoD) techniques to estimate the direction of a Bluetooth signal. AoA determines the angle at which a signal arrives at a receiving device, while AoD determines the angle at which a signal is transmitted from a transmitting device.
Bluetooth Use in Telematics
Bluetooth technology is primarily used in telematics for vehicle connectivity to establish wireless connections between smartphones and/or tablets and in-vehicle systems. This connectivity enables companies and their drivers to monitor vehicle data and to receive alerts for any issues that may need immediate attention.
