Digital two-way radio communications
DMR Communications or Digital Mobile Radio is a standard of digital two-way radio that allows the products of different two-way radio manufacturers (e.g. Motorola Solutions and JVC Kenwood) to work together seamlessly on any two-way radio network, such as the Orion Network.
The technology offers users clarity, extended range and security including integrated data applications such as text messaging, location tracking and dispatch capability.
DMR is the fastest growing digital radio technology globally and due to the cost-effectiveness and flexibility of the technology, is being invested in globally by digital application partners to provide enhancements to the use case. DMR is rapidly being adopted in mining, construction and industrial markets due to it providing the easiest migration path from analogue. DMR technology is backward compatible with analogue and can therefore be used in locations where both analogue and digital operations are required.
Facilitating interoperability across platforms, DMR communications are deployed where safety, productivity and connectivity are non-negotiable. CSE Crosscom is the owner and operator of the largest DMR Communications network in Australia – the Orion Network.

A DMR communications platform is extremely flexible and can cater for the unique needs of specialised sectors including social services, transport and logistics, local government, waste management and security.
Benefits of DMR Communications
- Can be deployed in a range of structures, even tunnels
- Simultaneous voice and data transmission
- Cost effective – advanced network infrastructure not required
- Scalable platform capable of covering large geographic areas
- Is backward compatible with analogue making migration easier
- Has radio equipment that is capable and approved of having CB frequencies
DMR system options
An affordable solution, CSE Crosscom specialise in simple and complex DMR Communication solutions including Tier II and Tier III modes of operation.
DMR Tier II – Licensed Conventional
The DMR Tier II standard was designed to provide simple and cost-effective digital replacements for conventional analogue two-way radio systems. DMR Tier II is a two way radio solution covering licensed conventional radio systems, mobiles and hand portables operating in the UHF 403-520 MHz and VHF 148-174MHz frequency bands.
The conventional system targets the need for spectral efficiency, advanced voice features and integrated IP data services in licensed bands for high power communications. The ETSI specifies DRM Tier II as two-slot TDMA in 12.5kHz channels.
DMR Tier III – Licensed Trunked
DMR Tier III, as defined by ETSI, covers trunking operations across the frequency bands 66-960 MHz. The standard specifies two-time slots in channels of 12.5 kHz, and is similar to TETRA in that it supports voice and short messaging functionalities across a wide range of formats. However, compared to TETRA, it doesn’t come with the high price tag.
