When is DMR the right choice?
Where communication has to be self-governed and independent of any outside network, a DMR base station is the most direct answer.
What a DMR system gives you
The system lives in your own equipment room, so a public-network outage or an external fault does not touch field communications.
One frequency carries two conversations, doubling spectrum efficiency while keeping voice clear and interference-resistant.
Emergency and priority calls can pre-empt a channel, so the instruction gets out at the moment it matters.
A smooth path from a single base station to a multi-carrier trunked system, with capacity added as the operation grows.
DMR base station architecture
Carries data exchange and interconnection between nodes in the system.
Interfaces to external systems and other networks for interworking.
Runs call control, user management and business logic.
The transmit and receive core for digital voice and data; several units form a trunked cluster.
Consolidates the output of several repeaters into a single path.
Handles uplink and downlink interleaving and route management.
Converts RF to digital IF for transmission out over fibre.
Isolates uplink from downlink, improving communication stability.
What the system is built from
Carries the DMR digital voice and data switching core; units cascade to grow from one base station into a multi-carrier cluster.
Consolidates several channels into one low-loss output, with capacity held back for later expansion.
Handles uplink and downlink interleaving and route management, distributing to each link by zone.
Carries digital IF over fibre, providing the interface onto the coverage system.
Isolates uplink from downlink, raising stability and cutting self-interference.
Where it is used
Tell us the user count, the dispatch requirement and what is already installed — one conversation settles the system size and how it grows.
DMR digital base station FAQ
The questions we hear most often on selection, certification and delivery.
Didn’t find your question? Ask an engineer →Capacity depends on the number of repeaters fitted; each DMR repeater provides two TDMA time slots. The cabinet is sized during system design.
DMR repeaters can operate in mixed analog/digital mode to support migration from legacy analog fleets.
Repeater status is reported to the network management system and NetFlex.
Yes. Additional repeaters can be added to the cabinet or networked from another site.
