dPMR Markets & Applications

Business and industry users have a basic need for flexible, efficient and cost effective communications systems and this was the fundamental reason for the development of the dPMR standard by ETSI, whose members did not consider that current digital radio standards really addressed the issue of low-cost.

We could spend a long time discussing the relative merits of FDMA, TDMA and CDMA technologies for this market but as far as most end users are concerned, it doesn’t make any difference. Provided the application software does exactly what the user requires, it does not matter whether the carrier is WiFi, WiMax or whatever.

The emphasis with dPMR is on a fully functional radio system that can seamlessly integrate with IP networks and offer customisable application software which will have tailored solutions to business communication needs up and running in minimal time. Combined with the true low-cost approach that is the core of the dPMR protocol, the overall result is the optimum solution for users and network operators alike. Of course not all business and industry users have the same needs. For this reason dPMR has been sub-divided into 4 separate functional modes.


dPMR Mode 3

This is the dPMR solution for either very large B+I users or government services where wide area multisite, multichannel trunked repeaters can offer up to national coverage if required. dPMR radio equipment can be seamlessly integrated into existing IT networks with both text messaging and voice calls using the voice and data functionality of dPMR. Solutions already exist for PC based remote control of dPMR base stations to give completely configurable dispatcher functionality. dPMR Mode 3 also offers users the possibility to operate efficiently in ‘direct mode’ separately from the network or beyond the coverage area of the network for special purposes such as on-scene activities.

Example - Highway Administration
Having an effective wider coverage than analogue radio with networking capabilities, dPMR does not limit the area where you want to, or can, cover. It offers reliable communication for one section of a roadway, or along an entire route.

Public Safety
dPMR is an effective alternative both in terms of communication coverage, system setup and cost compared to Tetra. It is a viable solution irrelevant of the economic times.

Government
The wide-area coverage potential of dPMR may suit governmental agencies that need to be in contact with their own or other agencies wherever they may be located.

Transportation
With the flexibility to call individuals, groups or all radios, dPMR allows you to communicate with desired working vehicles effectively and efficiently. Fleet management applications will also improve efficiency and versatility of the systems.


dPMR Mode 2

This is the dPMR solution for normal B+I users or local government services where a normal repeater coverage area is adequate. Where needed, dPMR Mode 2 can also provide wide area coverage using its special co-channel multirepeater functionality. dPMR radio equipment can be seamlessly integrated into existing IT networks with both text messaging and voice calls using the voice and data functionality of dPMR. Solutions already exist for PC based remote control of dPMR base stations to give completely configurable dispatcher functionality. What always remains is the advantage for dPMR that a single repeater failure results in the loss of one voice channel not two or more. dPMR Mode 2 also offers users the possibility to operate efficiently in ‘direct mode’ separately from the network or beyond the coverage area of the network for special purposes such as on-scene activities.

Example - Hospitality
Whether a serene resort or the excitement of a casino, a dPMR system will offer management security and robust communications to run a tight ship.

Security
Secure communications allow incident response to be fast and effective. Critical when the unthinkable happens. Utilities Whether a security tool, a general communication tool, or a data tool, dPMR offers utility operators a reliable tool for all communication needs.

Utilities
Whether a security tool, a general communication tool or a data tool, dPMR offers utility operators a reliable tool for all communication needs.


dPMR Mode 1

There are many commercial users such as building sites, shops, hotels, sports centres etc where the use of repeaters is not required. dPMR Mode 1 offers the optimum radio functionality for such local area coverage. Base station (non repeater type) radios could still be interconnected to IT networks via IP and exploit both text messaging and voice calls using the voice and data functionality of dPMR.

Example - Campuses
dPMR offers safety and security to your students and staff with minimum cost and easy operation.

dPMR 446

Finally there is dPMR446. This is a special licence free version of dPMR. Because it is licence free, the transmit power is limited and only handheld radios with fixed antennae are permitted. Despite these limitations, dPMR446 will be perfectly adequate for many small commerces and recreational users who can exploit both text messaging and voice calls using the voice and data functionality of dPMR.

Example - Leisure
With high audio quality, dPMR446 enables you to communicate clearly with your friends when skiing, hunting, biking, touring and so on. Enjoy greater coverage than equivalent analogue models without the noise analogue radios have.
