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, 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 offering customisable application
software that 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 3 separate functional
modes.
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. MORE>>
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, dMPR
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. MORE>>
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. MORE>>
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. MORE>>
Markets and Applications:
Campuses
dPMR offers safety and security to your students and staff with minimum
cost and easy operation.
Highway Administration
Having an effective wider coverage than analog radio with networking
capabilities, dPMR does not limit the area where you want to, or can
cover. Reliable communication for one section of a roadway, or along
an entire route.
Leisure (dPMR446)
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.
Public Safety
dPMR is an effective alternative both in terms of communication coverage,
system setup and cost compared to Tetra. 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.
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.
Systems Providers
The 6.25kHz channel spacing can potentially allow you to increase system
capacity. Leverage wide area capabilities to migrate an analogue system
to digital at your own pace.
