The Special Interest Group (SIG) has announced a new standard for Bluetooth 5.1. The biggest innovation is a feature dubbed Direction Finding, with this the user can determine which direction the signal is sent. Reporting from the Android Pit page, Wednesday (01/30/2019), this allows you to determine the location and accuracy of only a few centimeters.
According to GIS, the new location will play a major role in indoor navigation and replace WLAN-based positioning in the long run. GPS positioning can also be improved, especially in places with poor GPS reception. Of course, the location of the key that is misplaced or the like will also be more appropriate.
In addition, the new Bluetooth 5.1 feature embedded is Generic Attributes (GATT) which is optimized to achieve faster installation. In addition, the transmission speed is higher, and the Random Channel Index is increased to prevent data packets from experiencing interference during transmission, which results in interference or disconnection.
Previous versions of Bluetooth 5.0 present a wide transmission range (up to 240 meters), lower power consumption, faster transfer speeds (up to 2 Mbps) and the ability to pair two audio devices with other devices.
