Quick answer: Analogue radios are the simpler, lower-cost option and work with older radio fleets. Digital radios (DMR) give clearer audio towards the edge of coverage and, on some models, add features such as text messaging and GPS. Many current radios, including the Motorola R7, work in both analogue and digital mode, so a business can move to digital in stages.
How analogue and digital radios differ
- Audio quality: analogue audio becomes noisier as you move away from other radios or a repeater. Digital audio stays clear until the signal drops out, and background noise is filtered more effectively.
- Capacity: DMR digital uses two time slots on one channel, so a single frequency can carry two separate calls.
- Features: depending on the model, digital radios can offer text messages, GPS location, private calls and encryption options.
- Battery: digital radios transmit in time slots, which can help them last longer on a charge.
- Compatibility: a radio in digital mode cannot talk to an analogue-only radio. Dual-mode radios can be switched to analogue so they keep working with an existing fleet.
Which should you choose?
- Small team on one site with analogue radios already: stay analogue, or buy dual-mode radios so you can upgrade later.
- Larger sites, noisy environments, or a need for text, GPS or call privacy: choose digital.
- A mix of old and new radios: choose dual-mode radios and migrate in stages.
Range and coverage also depend on the frequency band and the environment. See our guide to fixing weak coverage and dead zones.
