Abstract
At this moment, in many European countries the analogue PMR (Private Mobile Radio) communications structure is being replaced by a new digital system based on the TETRA (TErrestrial Trunked RAdio) standard. This new standard provides higher quality, more flexibility and improved security of communications. An interesting aspect of TETRA is that it provides data communications facilities. This makes it possible to do automatic tracking of the location of police cars, access medical information from an ambulance or do administrative work at the location of an incident, and many other things. The Dutch police has developed an application to access their central information systems called Mobipol. This application currently runs on GSM and RAM Mobitex (a commercial packet-switched network) wireless communications infrastructures. In the future, TETRA will be used instead. Mobipol uses the TCP/IP protocol to communicate. Unfortunately, TCP/IP functionality has been introduced in the TETR...
