== Configure Cell Locations

To determine geographic location estimates based on the serving cell, OsmoSMLC
needs preconfigured global positions by latitude and longitude, for each cell of
each BSC.

On the `cells` configuration node, cell locations can be indicated by LAC and
CI, or by Cell Global Identity. The following example configures the position
for a cell by LAC 23 and CI 42:

----
cells
 lac-ci 23 42 lat 12.3456 lon 23.4567
----

The following example configures the position by a Cell Global Identity with
PLMN 001-01, LAC 2 and CI 3:

----
cells
 cgi 001 01 2 3 lat 34.5678 lon 45.6789
----

If a cell's latitude and longitude is not configured, all location requests for
subscribers served by that cell are answered by a BSSMAP-LE Perform Location
Response without a Location Estimate and  LCS Cause "Facility not supported".
