The Bluetooth Special Interest Group (SIG) has revealed a new feature that will allow for extremely accurate positioning and proximity sensing. The new feature will equip Bluetooth-enabled devices – that provide location services – with the ability to determine the angle at which a Bluetooth signal enters and leaves a device, to not only track down an item but to also understand its direction.
Proximity solutions today use Bluetooth to detect devices when they are near each other, and also to determine the distance between them. An item finding solution, for example, will let a user know when a personal property tag is nearby. But with the new direction-finding feature, the solution would allow users to also determine the direction, thereby greatly enhancing the user experience.
Positioning systems, on the other hand, can also greatly benefit from the new feature when determining the physical location of a device. These systems – which only achieved meter-level accuracy until now – with the new feature, will be able to track items down to the centimeter. Not only will this help locate missing gadgets, but the new feature could also be used to improve the accuracy of tracking in indoor spaces where Bluetooth beacons are used to help people navigate.
“Location services is one of the fastest growing solution areas for Bluetooth technology, and is forecasted to reach over 400 million products per year by 2022,” said Mark Powell, Bluetooth SIG Executive Director. “This is great traction and the Bluetooth community continues to seek ways to further grow this market with technology enhancements… driving innovation and enriching the technology experience of [mobile] users worldwide.”
