The MapEM system is designed to create RF electromagnetic field level maps over large areas, including urban environments and public infrastructure zones. It combines a MonitEM monitoring device installed on a vehicle with dedicated electromagnetic mapping software.

As the vehicle moves through the area, the system measures electric field strength in V/m and associates the results with geographic position data. This provides a clear, field-based view of RF exposure levels at street level.

MapEM is suitable for technical teams requiring a practical drive test solution for RF exposure assessment, public communication, infrastructure follow-up and comparison of electromagnetic field levels over time.

Advantages

Large-area RF assessment: designed for electromagnetic field mapping across cities or extended geographic zones.
Vehicle-mounted measurement: the monitoring device can be installed on a vehicle roof using a magnetic base for field campaigns.
Georeferenced results: measurement data can be downloaded in Access, KML or CSV format.
Visual field level maps: the software superimposes measured levels onto a map for clear technical analysis.
Year-on-year comparison: supports monitoring of changes linked to infrastructure or technology evolution.
Sensitive point detection: helps identify locations with higher RF field levels for further investigation or corrective action.
ITU-T K.113 compliance: suitable for RF exposure drive test applications aligned with this recommendation.

Why choose MapEM

MapEM provides a practical and field-oriented solution for RF electromagnetic exposure mapping. Its vehicle-mounted configuration enables efficient coverage of large areas, while the software transforms measurement data into visual and georeferenced field level maps.

The system is especially relevant when technical teams need to combine repeatable measurements, ISO 17025 accredited probe calibration, street-level RF exposure visibility and clear reporting outputs in standard formats such as KML, CSV and JPG.

With its interchangeable probe architecture covering applications from 100 kHz up to 90 GHz, MapEM can be configured according to the required frequency range and field type.
