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?

[Hemamali]

NLOS means Non line of sight conditions, the reason why BT5.0 could be interesting is: range is improved dramatically, power consumption is better and they are going to add AoA/AoD features which will really help to improve the accuracy with minimal Hw deployment. but we need to see how this will span out in real complex indoor environments, BT being a very Narrow band system.

commercial RTLS systems based on Nordic or TI BLE chips are claiming down to 1m accuracy with optimized installations can you please share more details regarding these commercial systems? what are those companies able to achieve <1m accuracy in real world?
