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 name | Data type | Description |
|---|---|---|
| LINK_ID | Integer (4) | The unique identifier for a topology segment associated with a CORE MAP link. |
| PERCENT_TOPOLOGY_SEGMENT_START | Double (8) | The percent of the segment where the attribute starts, from the reference node. For example, 1. |
| PERCENT_TOPOLOGY_SEGMENT_END | Double (8) | The percent of the segment where the attribute ends, from the reference node. For example, -61. |
| ISO_CODE | Char(3) | Three letter ISO code indicating the country containing the segment. For example, FRA for France. |
| TIMESTAMP | Date (8) | Date of source file creation, formatted as (dd/mm/yyyy). |
| CARRIER | Char (10) | A unique identifier for the network carrier, as indicated by the MCC and MNC values. For example, 505002. |
| MCC | Char(3) | The Mobile Country Code, which indicates the country associated with the Mobile Network Code that uniquely identifies a cellular carrier. |
| MNC | Char (3) | The Mobile Network Code, which indicates the network associated with the Mobile Country Code that uniquely identifies a cellular carrier. |
| LACTAC | Integer (4) | A geographic division indicator of the mobile network. For example, 215524420. |
| OPTIMAL_STRENGTH | Char(15) | The signal strength as indicated by the highest quality RSSI value available per segment.
|
| STRENGTH_HIGH | Integer (4) | The highest of the observed RSSI values on the segment. For example, -68. |
| STRENGTH_LOW | Integer (4) | The lowest of the observed RSSI values on the segment. For example, 103. |
| STRENGTH_MEDIAN | Integer (4) | The median of the observed RSSI values on the segment. For example, -98.5. |
| INTERFACE | Text(15) | This identifies which access modes are available.
|
| SID | Char(5) | The System ID, which indicates a cellular carrier using a CDMA interface. |
| NID | Char (5) | A Network Identity number, which indicates that a cellular carrier is using a CDMA interface and SID numbering. |
| CONFIDENCE | Char (10) | This indicates confidence, based on a HERE proprietary algorithm. Available values are:
|
| BRAND | Char (50) | The brand name corresponding to the CARRIER value. |
| COUNTRY | Char (45) | Name of the country containing the area under examination. |
| OPERATOR | Char (80) | The full name of the operating business. |
