PNM Passive Network Monitor
Coverage Data from a User's Perspective
PNM is a multi-technology, multi-channel measurement platform. It is designed to operate with almost any device and supports 2G, 3G and 4G networks as well as PMR including TETRA. Using passive probing, it provides a very cost-saving way to determine cell and coverage information. Since PNM uses standard enduser devices,it delivers a maximum user perspective (e.g. when compared to scanners), because only actually usable radio cells are shown. Thus, the system is also suitable for use in forensic science or to support cell measurements in police investigations. PNM provides automated measurement and over the air data transfer, with data fully compatible to Focus Infocom's complete post processing chain.
PNM has been designed as a versatile platform for numerous hardware setups from mobile hardcase or backpack systems to 19" multi-channel systems.
PNM does not need heavy and expensive ressources, it works with just a few standard modules, making it a highly cost-efficient solution.
PNM pictures network coverage from your subscriber's perspective, because it tells you exactly if a device can actually use an existing cell.
Out of the Box
PNM works with many commercial end-user devices right out of the box. Additionally, PNM supports TETRA- and GSM-R devices.
PNM can be fully automated and even configured to start measurement at startup of the controlling computer.
Data collected with the PNM platform is automatically transferred to FIMAS PNM for visualization and evaluation.
