The National Emergency Medical Services have been developing their systems for several years. DGT’s offer for the ambulance service includes supplies of radio and telephone systems, integrated communication systems ranging from one dispatch centre to province installations. The solutions provided by DGT can operate with various communication systems including those already possessed by individual units. An ideal idea is to merge the old radio infrastructure with the new one and combine them both into a single communication system. Moreover, integration with fixed or mobile telephony and virtual radiotelephones can be considered.
