Mobile communication under your own control

Depending on the purpose, radio network scalability requirements can range from radio coverage of a very large area with a small number of users, to linear coverage of highways and railway lines, to a higher number of users in urban public transport and industry.

The size of a radio network is defined by the type and extent of the area that the radio stations are intended to cover. This involves the topography of the area, i.e., whether it is flat, hilly, or mountainous terrain, a water or forest area, or whether it is grassland or agricultural land. The nature of the area's settlement is also important, i.e., whether it is a densely populated urban area with tall buildings and narrow streets, a suburban character with low-rise buildings, or a rural region. Generally, several radio stations are required to maintain sufficient radio coverage of a larger area and to ensure a certain level of redundancy. Customer mobile workers roam within this area.

For all the applications described above, an economically reasonable, technically sophisticated, and secure solution can generally be found by deploying a DMR Tier III radio network.
