Team,

Does TI have any guidance on 2.4GHz triangulation for indoor positioning (i.e. BLE radio and BLE beacons)?

Hi Carolus,

I would recommend that you take a look at our AoA solution. This is currently in its infancy, more collateral will be released in the coming months.

Fredrik,

Thanks for the response. The AoA demo certainly looks promising. I know its still in its infancy as per yoru comment, but can you comment what the target accuracy of this Angle of Arrival demo would be from a Real-Time Locating System (RTLS) standpoint? I know that triangulation with existing Bluetooth 4.0 and RSSI is only accurate to a 3-5 meters, but I have heard that Angle of Arrival will be accurate to less than 1 meter.

Hi Carolus,

Take a look at our BOOSTXL-AoA getting started page. A bit down you will find the angular accuracy measured in an anechoic chamber.
