Nordic Chipsets can support Indoor Location Tracking feature?

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?

  • The only I know is that already with nRF52832 with standard 1Mbps air speed and +4dBm Tx power (+ good HW design) you can make 1km+ range on free air. With nRF52840 with higher Tx Power and potentially long-range air-speeds it can be much more. Still not really practical for any precise location tracking as far as I know... I don't understand what do you mean by NLOS (and how you would like to quantify it?) also don't understand why BT5.0 is so interesting for Indoor Location Tracking (smells like buzzword a little bit...). When it comes to SW solutions on Nordic chips I don't have any conclusions to share, I just know that it's possible to do basic system with <5m accuracy already with nRF51 and commercial RTLS systems based on Nordic or TI BLE chips are claiming down to 1m accuracy with optimized installations...
