Authorities and organizations involved in security activities using digital trunked radio systems have specific requirements regarding the "Service Level Management" of speech-, data- and short message services they use. During operation, the radio network coverage in the active zones has to be analyzed under near real-time conditions. For this purpose, we developed a system to calculate, in near real-time, the entire radio network coverage using radio planning data and network management system alarms. Visualization is done by zoomable geographical views accessible via web browsers. The overall use of parallel processing was indispensable in order to process radio network data in real-time from more than a thousand transmitting stations. LabVIEW 8.5 has proven to be an efficient and intuitive tool programming powerful multicore-applications.
