The transparency and security of Digital Mobile Radio can not befound in large public networks.

The analog radio is operating in many areas for many years an essential part of communication. In addition to the BOS (Germany), authorities and organizations with security tasks, especially for users in public transportation, at federal highways, industry and utilities, will not give up the unique features of a professional mobile radio. In addition to TETRA,  DMR (Digital Mobile Radio), standardized by ETSI, is another digital (Critical) communications technology renewal. The migration from analog to digital offers the best features of new possibilities. according to Jörn Schulze, Senior Manager PMR technology, Telent

The analog radio operation has proved itself in practice. The number of manufacturers of analog wireless technology has declined considerably in recent years. The supply of spare parts, and thus a secure network operation, thereby becoming increasingly difficult and is associated with higher costs. The new digital mobile radio standard for the replacement of the analog broadcasting is DMR.

A migration decision is almost always associated with the question of whether the use of the functions of a public network is sufficient. The public mobile now offers many features for voice and data services. The expansion of mobile networks in Germany and the competition between different providers is leading to low prices for mobile phone users.

Before making a decision for the upkeep of their own professional mobile radio network a number of criteria are to consider. The decision to use a private network is based in particular on a number of aspects related to;  its own network availability,  the responsibility of the network. The user and the operator must determine the necessary availability of its network, its radio system, its technology and its base stations. Furthermore, he can even determine whether and how long the power operation is to be maintained by an independent power supply. By continuously monitoring the network errors and failures are detected early or even can be avoided.

This transparency and security can not befound in large public networks.

The use of a DMR Tier III Systems offers unique capabilities for voice and data.
