The Bluetooth Special Interest Group (SIG) has announced a new direction-finding feature that is aimed at enhancing the performance of the Bluetooth location services solutions. The new feature allows devices to determine the direction of a Bluetooth signal, thereby enabling the development of Bluetooth proximity solutions that can understand device direction as well as Bluetooth positioning systems. By including the new direction-finding feature, Bluetooth proximity solutions can add device direction capability. For example, an item finding solution could not only let a user know when a personal property tag is nearby but also in what direction. The Bluetooth positioning systems can achieve meter-level accuracy when determining the physical location of a device. By adding the new direction-finding feature, these positioning systems could improve their location accuracy down to the centimeter-level. The direction finding feature is included in version 5.1 of the Bluetooth Core Specification, which is currently only available to developers. In addition, the Bluetooth SIG tool used to qualify new Bluetooth products is being updated to support this feature and will also be available to developers starting today. Fabio Belloni, chief customer officer and co-founder of Quuppa said: Bluetooth has emerged as the technology of choice for location services, allowing companies to build robust, ...
