The developers announced the release of the Bluetooth 5.1 standard, which includes expanded support for location services with an accuracy of 10 centimeters..
The Bluetooth Specific Group (SIG) claims that the new protocol allows not only to estimate distance based on signal strength, but also includes two ways to determine direction using multiple antennas (on the phone or on the transmitter). Added DF technology measures the angle of arrival and departure of the signal.
According to the team, the new feature works so accurately that if your keys get lost on the couch, then thanks to the device it will be possible to determine which pillow to check..
The basic Bluetooth 5.1 specification became available on January 28th. The developers expect it to will lead to a new wave of gadgets that do not need GPS and Wi-Fi to get accurate location data. In addition, the device uses very little power, which makes it possible to design tiny computers that can be attached to any object..
IN SIG Expects Their Innovation to Have Impact on Retail, Healthcare, Manufacturing and IoT in General.
We previously reported that a Bluetooth chip has been developed for the IoT, powered by the energy of the surrounding radio waves..
