Hi Shay,
We are using Civil Location Information Format rather than Geospatial Location Information Format.
Looking into captures I done here, the location is being provided based on AP's location.
See configured location for AP

See results seen in RADIUS-Request for
Location-Data

And
Location-Information

You can find little more explanation under IETF RFC5580
here and
here
Please find also some an old but gold guide for specific
RADIUS attributes under WiNG system.
More documents can be found under
this portal link
Regards,
Ondrej
