DMR is mostly used by the clients for emergency operations or pure voice radio. But at the same time DMR offers something special, which can be used for both: the existing infrastructure and a saving potential accomplished by solutions, which normally are achievable only with enormous investments when using conventional technology.

Data Transmission on the 2^nd Time Slot

All 30ms speech and data are alternately transferred at the same frequency. This means, while using the voice radio on the first time slot the data transmission can be taking place on the second time slot without any interference regarding the voice communication on the first time slot.  In comparison to other solutions the specific advantage is obvious as many applications of GPRS, UMTS or LTE connections and also the monthly fees which accrue become superfluous. As a result the operation costs can be reduced at the locations of the company. Furthermore many locations often cannot be incorporated as they are located outside of the operating range of all network providers. From the economic point of view a dedicated lane specially installed no longer can be argued, but often this is the only solution.

What was missed up to now and why radio add value for the supervisory control technology!
