Why digital?
• Better coverage
• Significantly louder and clearer audio
• Longer battery life, longer duty cycles
• Far superior privacy
DMR supports different tiers of service - from
short-range license-free to larger, more
sophisticated networks:
Tier I - For commercial and leisure use with direct
mode operation (no repeaters allowed), fully
approved for use within Europe and no license is
required.
Tier II - For small to medium size licensed
systems. Radios can be used in direct mode or
with a repeater if significantly extended range is
required. Tier II repeaters can be networked to
increase the coverage area even further.
Tier III - For medium to large size licensed
systems. ‘Trunked’ repeaters are used giving
automatic access to multiple Channels which may
be extended and networked to support very large
numbers of radios or coverage areas.
Double the Channels
Using two slot simplex, DTEx radios split each channel in two to
deliver double the number of digital channels at no extra cost.
For example, if you are using a single analogue channel, the
same channel in digital mode will yield two channels.
