HERE Cellular Signals provides mobile phone coverage areas and associated details measured as a snapshot at regular time intervals. Information collected includes individual cell area coverage, carrier identification, signal type, measured strength and frequency bands. Globally, data is available for over 195 countries.
The product may be used in the transport and logistics space, where dispatchers and drivers need to be efficiently and effectively connected. It may also be used in the telecom space, to assess wireless network capability and penetration. Law enforcement and defence are also potential users for device identification and tracking.
HERE supply raw data in both linear and area datasets. All data is processed by NAVIGATE into separate layers inside an ESRI dataset with feature classes corresponding to an individual record. Coverage patterns of each of the network providers is presented.
HERE data is supplied as discrete, regional xml files. Our processes add the cell_id value from lookup tables which, together with mcc, mnc and lactac, enable the identification of a mobile cell and a link up to the cell tower infrastructure information. In addition, we add carrier name fields, country name and additional descriptive information relating to the coverage polygon record.
The polygons are provided as either signalClusters or servingareas (as defined in field coveragedefinition). Rf measurements from mobile phones and other location enabled devices are clustered into polygons for each cell. For any one cell, there may be a number of these cluster polygons and these are in turn used to generate a single servingarea polygon for that particular cell.
