Is Your Team's Safety Left to Chance?
Relying on standard mobile phones in remote environments creates a dangerous illusion of safety. The moment a worker steps outside that limited cellular footprint, they're completely cut off. This communication gap is more than an operational headache, it's a serious liability under the Health and Safety at Work Act (HSWA) 2015.
New Zealand's key industries often operate in our most challenging and isolated terrain: agriculture and horticulture, construction and civil works, emergency and disaster response, energy and exploration, forestry, maritime and fishing, and transport, logistics and fleet. For lone workers and remote teams in these fields, a vehicle breakdown, a sudden medical event, an equipment failure, or an unexpected environmental hazard can escalate from a manageable issue to a life-threatening emergency simply because there's no way to call for help.
This isn't only about meeting compliance obligations. It's about the fundamental duty of care every business has for its people. A robust lone worker alert system isn't optional when your staff operate beyond mobile reception, and our Lone Worker Safety NZ guide covers that duty in full, from risk assessment through to emergency response protocols.
What Is Satellite Communication and How Does It Work?
Satellite communication is a way of connecting that completely bypasses ground-based infrastructure. Instead of your device talking to a local cell tower, it communicates directly with a satellite orbiting the Earth, effectively a cell tower in the sky. This gives your team a connection almost anywhere on the planet, totally independent of the mobile network. Your standard mobile phone is a paperweight without a nearby tower; satellite technology eliminates that weak link, whether your team is deep in a forest, on a vessel far from shore, or on a remote construction site.
Key Satellite Networks for NZ Operations
Not all satellite networks are created equal. The network you choose affects call clarity, data speeds, device size, and coverage reliability across New Zealand. The two main types are Low Earth Orbit (LEO) and Geostationary (GEO).
Low Earth Orbit (LEO) constellations
LEO networks, like Iridium and Starlink, use a large fleet of satellites orbiting relatively close to Earth, roughly 550 to 2,000 kilometres up. They move quickly across the sky, handing your signal off from one satellite to the next. This gives low latency for crisp, natural-sounding voice calls, and true pole-to-pole coverage, making them exceptionally reliable across every corner of New Zealand, including the Southern Ocean. The low orbit also allows for smaller, more portable handheld devices, ideal for lone workers who need something they can carry easily, and performance is unaffected by mountainous terrain that can block signals to geostationary satellites.
Geostationary (GEO) networks
GEO networks, such as Inmarsat, use a few large satellites in a much higher orbit, around 36,000 kilometres up, moving at the same speed as the Earth so they appear fixed in the sky. This gives highly stable, consistent coverage over a vast region, excellent for fixed data terminals on vessels or at remote sites needing a permanent, always-on connection. Coverage is very stable across the main NZ landmass, though it can become less reliable at extreme southern latitudes, worth factoring in for maritime operators working that far south.
Industry-Specific Use Cases
Forestry
The problem: crews work in steep, isolated country with zero mobile reception. A machinery accident, medical event, or vehicle breakdown leaves workers with no way to raise the alarm.
The solution: Hytera P50 PoC devices for team coordination, an Iridium 9555 satellite phone for supervisors for clear, two-way emergency voice calls, and Garmin inReach satellite messengers for lone workers, providing GPS tracking and a one-touch SOS button that sends their exact location to responders. We perform on-site coverage mapping to identify black spots and design a hybrid radio/satellite solution, programming devices for seamless operation and providing vehicle-mounted charging so devices are always ready.
Maritime, marine and fishing
The problem: once a vessel is beyond coastal VHF and cellular range, it goes dark. Storms, equipment failure, or medical emergencies can leave a crew dangerously isolated.
The solution: a fixed Starlink Maritime or Inmarsat FleetBroadband terminal for reliable data and voice, an Iridium satellite phone as a primary safety device, and McMurdo or Ocean Signal EPIRBs and PLBs for worst-case scenarios. We provide expert installation of marine-grade antennas and terminals built to withstand the saltwater environment, plus system integration and long-term servicing plans.
Construction and civil works
The problem: large infrastructure projects in rural areas have patchy mobile coverage. Surveyors, machine operators, and site managers working in gullies or remote sections of a site are often isolated.
The solution: a Starlink terminal at the main site office to create a powerful Wi-Fi and communications hub, PoC radios like the Hytera P50 or Motorola TLK110 that roam between cellular and Starlink Wi-Fi, and satellite messengers for lone surveyors for tracking and SOS. We design and deploy integrated networks blending UHF/VHF radio, PoC, and satellite into one seamless system, providing total site coverage on a single platform.
PoC vs UHF/VHF: Which Is Right for Your Team?
| Feature | PoC | UHF/VHF Two-Way Radio |
|---|---|---|
| Coverage | Nationwide, via cellular/Wi-Fi | Localised, line-of-sight, expandable with repeaters |
| Infrastructure | Uses existing cellular networks | Requires your own repeaters for wide-area coverage |
| Licensing | None required | RSM licence usually required |
| Key advantage | Unlimited range wherever there's data | Highly reliable in a defined area, works with no external network |
| Best for | Transport, logistics, teams spread across cities | Construction sites, factories, forestry blocks |
Common Mistakes We Help Businesses Avoid
Over 25 years deploying communication solutions in New Zealand's toughest environments has taught us where things typically go wrong.
- Relying on consumer-grade devices: department-store gear often lacks the durability, battery life, and acoustic performance needed for commercial use in loud, wet, or dusty conditions. We only supply commercial-grade hardware from trusted brands like Motorola, Tait, Hytera, and Iridium, field-tested with proper IP ratings for all-day use.
- Neglecting battery management: a device with a dead battery is useless in an emergency. We design and install professional multi-bay charging systems and vehicle-mounted cradles so every device is charged and ready at the start of every shift.
- A "set and forget" mentality: buying a satellite phone is just the first step. Without regular testing, firmware updates, and plan management, a device may not work when you need it most. We offer managed service plans with proactive health checks, firmware updates, and subscription management.
NZ Compliance and Operational Considerations
- Lone worker safety: the HSWA 2015 requires businesses to manage risks for all workers, especially those working alone. Solutions should include Man Down alerts, regular check-ins, and a dedicated SOS button.
- GPS tracking: integrated GPS lets you see all assets on a single map, dispatch the nearest person to a job, and provide accurate location data to emergency services.
- Durability (IP ratings): NZ worksites are often wet, dusty, and rugged. Look for a high Ingress Protection rating, IP67 or IP68, meaning the device is dust-tight and can withstand water immersion.
- RSM licensing: satellite devices themselves don't require user licences, but a supporting UHF/VHF radio network usually does. Mobile Systems manages all RSM licensing needs to keep you compliant.
- Acoustic safety: in loud environments like factories or near heavy machinery, standard devices are unusable. We provide noise-cancelling solutions from brands like Sensear for clear communication that also protects hearing.
