Carrier segment feature class (Carrier_Segment)

The Carrier_Segments feature class indicates the general cellular signal information of the road. The feature class includes a high, median, and low strength value of availability, as well as optimal signal strength values without defining the carrier of the relevant signal measurement.


For a description of the attributes OBJECTID, Shape, GlobalID, and Shape_Length, see Esri® system fields .

Field nameData typeDescription
LINK_IDInteger (4)The unique identifier for a topology segment associated with a CORE MAP link.
PERCENT_TOPOLOGY_SEGMENT_STARTDouble (8)The percent of the segment where the attribute starts, from the reference node. For example, 1.
PERCENT_TOPOLOGY_SEGMENT_ENDDouble (8)The percent of the segment where the attribute ends, from the reference node. For example, -61.
ISO_CODEChar(3)Three letter ISO code indicating the country containing the segment. For example, FRA for France.
TIMESTAMPDate (8)Date of source file creation, formatted as (dd/mm/yyyy).
CARRIERChar (10)A unique identifier for the network carrier, as indicated by the MCC and MNC values. For example, 505002.
MCCChar(3)The Mobile Country Code, which indicates the country associated with the Mobile Network Code that uniquely identifies a cellular carrier.
MNCChar (3)The Mobile Network Code, which indicates the network associated with the Mobile Country Code that uniquely identifies a cellular carrier.
LACTACInteger (4)A geographic division indicator of the mobile network. For example, 215524420.
OPTIMAL_STRENGTHChar(15)The signal strength as indicated by the highest quality RSSI value available per segment.
  • Excellent
  • Good
  • Fair
  • Poor
  • No observation
  • No coverage
  • Observed (which is only valid if the interface is CDMA)
STRENGTH_HIGHInteger (4)The highest of the observed RSSI values on the segment. For example, -68.
STRENGTH_LOWInteger (4)The lowest of the observed RSSI values on the segment. For example, 103.
STRENGTH_MEDIANInteger (4)The median of the observed RSSI values on the segment. For example, -98.5.
