Nordic Chipsets can support Indoor Location Tracking feature?

[Hemamali]

Hi Nordic Team, Can you please share any information regarding Indoor Location Tracking feature/application that nRF52840 can support? does this have AoA/AoD? and can this provide any kind of physical layer time-stamping for ToF/TDoA algorithms? What's the best location accuracy that can be achieved using this silicon? If i want to develop nRF52840 based Indoor Location Tracking application what kind of support i can get from you? What's the preferred module platform? does Nordic supports API for location developers? what's the best LOS & NLOS range one can get using this SoC? Kindly share this information

THanks & Best Regards, Hemamali

thanks for your clarification! do you know what's the practical LOS/NLOS range can be achieved using latest Nordic BT5.0 solution? any real deployments based out of BT5.0 happened till now? if yes, what are the challenges seen with Sw timer/RSSI based schemes?

You are perfectly right and that's why chips with ToF are expensive systems. But AoA might be easier to achieve. And just to conclude: these companies claiming <2m RTLS accuracy are using various techniques but all are basically "lot of data processed heavily by the back-end" (seeing the same packet at different stations = different known locations and RSSI => trilat. + advanced filtering including knowledge of the topology from calibration phase => location).
