Poor Coverage and Dead Zones
Topping the list is poor signal coverage and frustrating dead zones. New Zealand's terrain, dense bush, hills, mountains, creates real obstacles for RF signals, and forestry, agriculture, construction, and transport teams routinely report blackouts that are a genuine safety risk, not just an inconvenience.
How to Fix It
- Install a repeater: placed on a high point, a repeater receives a weak signal and re-transmits it at higher power over a much wider area, generally the most effective fix for dead zones.
- Choose higher-wattage radios: 5-watt handhelds penetrate obstacles and travel further than lower-power units.
- Get a coverage survey done: before investing in a full system, a professional survey identifies dead zones and informs antenna and repeater placement.
- Add satellite backup: for genuinely remote operations where repeaters aren't practical, a satellite phone covers the gap. See our satellite comparison guide.
See our antenna and range guide for more on eliminating coverage gaps.
High Equipment and Licensing Costs
The upfront cost of commercial-grade handsets, vehicle-mounted units, and RSM licensing is a real hurdle for smaller businesses and volunteer groups, especially set against the apparent simplicity of just using mobile phones.
How to Fix It
- Consider hire or lease: for short-term projects or seasonal work, hiring equipment avoids the large upfront cost entirely.
- Look at total cost of ownership, not just the sticker price. A durable, reliable radio typically costs less over its lifespan than a cheaper alternative that fails early.
- Ask about certified used equipment as a way to access commercial-grade reliability at a lower entry cost.
See our UHF radio guide for current licensing figures and requirements.
Interference and Frequency Congestion
In busy urban and industrial areas, crowded spectrum causes garbled messages and crosstalk. This is especially common on older analogue radios or public CB channels, where a nearby business's radio traffic or heavy machinery can bleed straight into your signal.
How to Fix It
- Upgrade to digital (DMR): digital radios filter background noise and reject other analogue transmissions on the same frequency far more effectively.
- Secure a licensed frequency through RSM rather than relying on crowded public PRS/CB channels.
- Use CTCSS/DCS privacy codes to filter out transmissions from other users not on the same code, though this isn't true privacy.
- Train the team to keep transmissions short and disciplined, reducing unnecessary chatter on the channel.
See our radio licensing guide for how frequencies are managed in NZ.
Limited Battery Life
A radio dying halfway through a shift is more than an annoyance, it's a safety risk for lone workers and remote teams. Cold, damp conditions accelerate battery drain, exactly when reliable communication matters most.
How to Fix It
- Invest in high-capacity batteries designed for long shifts. See our battery range.
- Run a battery rotation schedule for multi-shift operations, with charged spares ready at the start of every shift.
- Use intelligent multi-unit chargers that condition batteries and extend overall lifespan.
- Keep batteries warm in cold conditions, inside a jacket or an insulated pouch, to prevent rapid drain.
Outdated Legacy System Compatibility
Many organisations still run decades-old analogue networks. As manufacturers focus on DMR, spare parts and support for old analogue gear dwindle, and mixed fleets of old and new radios often can't talk to each other properly.
How to Fix It
- Plan a phased migration rather than a sudden switch, upgrading critical teams first while hybrid radios bridge the gap.
- Use hybrid (dual-mode) radios that operate on both analogue and digital channels during the transition.
- Document your existing system fully, frequencies, channels, user groups, before making any changes.
- Prioritise interoperability in any new equipment purchase.
User Interface Complexity
Modern digital radios pack in private calling, GPS, and text messaging, but the resulting menu complexity can genuinely compromise safety when someone can't quickly find the right function under pressure.
How to Fix It
- Choose intuitive models that can be pre-programmed to hide non-essential features for frontline staff.
- Run structured training, covering both basic operation and emergency procedures until it's muscle memory.
- Provide laminated quick-reference guides for field or vehicle use.
- Pair new operators with experienced users for real-world, hands-on guidance.
RSM Compliance and Licensing Complexity
Radio spectrum is a finite, managed resource, and getting the correct licence, frequency allocation, and equipment compliance right can feel like a genuine administrative burden, one with real legal consequences (fines, confiscated equipment) if it's ignored.
How to Fix It
- Work with an approved radio engineer for anything complex, like a private repeater or an exclusive commercial frequency.
- Plan ahead, licensing and frequency allocation take time, so don't leave it until the last minute.
- Keep detailed records of equipment, serial numbers, licensed frequencies, and licence expiry dates.
- Use a professional provider who manages licensing on your behalf. See our radio licensing guide for current RSM fees.
Getting the Right System in Place
The core takeaway across all seven complaints is the same: most trace back to a mismatch between the equipment and the environment it's used in, not a fundamentally broken technology. Mobile Systems Limited is 100% New Zealand owned and based in Mount Maunganui, with over 25 years designing communication systems that fit the actual environment, strategic coverage planning, proactive power management, and the right underlying technology, DMR, PoC, or marine VHF, for the job.
