CC1200DK: Triangulation for getting location using CC1200 Development Kit

Hi,

Request to let me know if it is possible to get a triangulation algorithm for determining the location of a Tag by using CC1200 Development Kit as 3 Anchors and 1 tag.

Regards,

Rohit.

    Rohit,

    We do not have such a thing, but theoretically this is possible. There are two main ways, signal strength based (RSSI) or Time of Flight (ToF) based. With RSSI you will experience issues with multipath fading and with ToF you will experience issues with resolution.

    • For RSSI, log the reported RSSI for a given distance and use it as a lookup table, but be aware of multipath issues.
    • To use ToF you should be able to use the SYNC indicator GPIO (option 0x06, see user guide) and then use that timing information to get time of flight. Please note that the time resolution is proportional to the datarate and therefore using CC1200 for this you will need to be using the highest datarate possible.
