Digital Mobile 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 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 partners with the Orion Network, the largest DMR Communications network in Australia, to deliver unrivalled performance.

DMR System Options
A DMR communications platform is extremely flexible and can cater to the unique needs of specialised sectors including social services, transport and logistics, local government, waste management and security.
An affordable solution, CSE Crosscom specialises in simple and complex DMR Communication solutions including Tier II and Tier III modes of operation.
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.
