Real World Range of AoA/AoD and Bluetooth 5.1 Indoor Capability

[Dave_couling]

I've seen a few demos of the AoA and AoD features of Bluetooth 5.1.  In general these demos are highly controlled are done at ranges of ~1m between the Tag and Receiver.  For indoor Location/Positioning was is the realistic range that AoA/AoD will work considering the effects of indoor multi-path propagation?  There has been much made about the increase accuracy of 5.1 compared to traditional RSSI triangulation, but I'm unclear how it address the indoor multi-path problem.  Can some comment on this?  Is the method uses less prone to these issues?

Hi Dave

Both these questions depend heavily on the antenna array and software that processes the IQ samples. We do not have any set in stone details on the range or what antenna array we plan to use as of yet, but we plan to provide an antenna reference design, software examples, and a whitepaper at a later point in time. Sadly, we don't have an estimate of a release date for these.

Best regards,

Simon
