Bluetooth 5.1 has new direction finding feature

First of all, the way this direction finding works differs a lot from how beacons work. With beacons, it's your phone that does the processing and the beacon that sends a signal.

If this standard works more or less the same as other indoor positioning services (IPS) available on the market, it will require a few antennas on the ceiling to triangulate the position of the device, it means the processing is now done on the antenna instead of on the device.

The big problem with all the vendors nowadays that don't use computer vision to track somebody or something is that their solutions require physical tags with batteries. But if it becomes part of the Bluetooth standard, every person will have a potential tracking-device in their pocket.

What you think? Will this finally bring the breakthrough for indoor navigation?
