Correct LoRa Gateway for TDOA?



  • I am setting up a asset tracking system around my city, and recently brought a RAK Gateway and the Arduino MKR WAN 1300(end device)Before I buy 3 more which is required for TDOA(GPS-free) location can anyone please tell me if the gateway i purchased us derived from the Semtech's V2 reference design? so TDOA is possible.

    to be more specific does this gateway support fine-timestamp support and can I get the license the key to decrypt this fine-timestamp as it is encrypted. This is required for TDOA localization.

    Thanks.

  • Hi, I would like to know the same thing. Thanks.



  • To my understanding these gateways use the standard Semtech Ic's and the software that is run on them is up to you.



  • Any official answer?



  • @jerylcook
    It definitely has all hardware for it. I have tested GPS and it works well. For TDOA, GPS must provide PPS input to SX1301. You can see that connection is done with a jumper cable between GPS and gateway board. I think that this will be gateway firmware bug or it lacks this feature.



  • I should have been clear. i meant for a GPS-less device, to obtain location by TDOA...i had to attach a ESP8266 and do a wifi sniff to obtain signinal strength of nearest wifi...and simpled used SigFox Geolocation : https://www.sigfox.com/en/sigfox-geolocation in
    my application(my application after data is sent from device to TTN). etc.
