Nowadays police operations can be of highly different types. The spectrum reaches from the protection of major activities and events, the establishment of mobile control centers over operations covering catastrophes all the way to the surveillance of persons and the monitoring of critical infrastructures and traffic segments. The demands on the means of communication and the types of required and exchanged information are therefore highly diverse.
Access to police search systems, exchange of emails and also transmission of real time videos from an event location as well as the transmission of live data to other units are important factors for increasing the efficiency of operations.
In particular the possibility of a flexible video transfer becomes more and more important. There are many different operation scenarios. They include scenarios such as the transfer of video data from a license plate data collection point to the local unit that performs the vehicle inspection, the transfer of video information from demonstrations to the operations centre, or the transfer of a video clip covering an object observed to special police forces. The data rates necessary for this are not reliably available in many wireless communication systems used today.
