Fine timestamp support on RAK 7249 for GEO location services

Hi I was wondering if the RAK 7249 supports “fine time stamping” for Geo location service. From what I read this is a SEMTECH proprietary technology which requires licensing. This is needed to provide geo-location by triangulation or better time difference of arrival. I’m working on several projects which would make this very attractive. In my case the used Gateways are all RAK 7249.
