Mobile Systems Limited supplies rugged two-way radio systems for construction sites across New Zealand, built to handle dust, drops and constant background noise. Our core site range covers the Hytera HP702 and HP782 digital portables, paired with Sensear SM1R and SM1P2 noise-cancelling headsets so your crew can still hear instructions over machinery. For multi-level builds and basement car parks where mobile signal drops out, we fit Cel-Fi GO G41 cellular boosters and Hytera repeater base stations to close the gap. We also supply VMS trailers for traffic management and can integrate lone worker monitoring for staff working alone on site. As a brand-independent advisor, we recommend the setup that suits your site, not the easiest sale.
Two-Way Radios Built for Site Conditions
Hytera HP702 and HP782 Digital Portables
Our most-supplied handhelds for construction crews. Both are DMR digital radios built to survive drops, dust and vibration, with clear digital audio that holds up over reversing beepers, saws and generators. We programme every unit to your channel plan before it leaves our workshop.
Motorola R5 VHF Portable
A solid alternative where a VHF site licence already exists or open-ground coverage matters more than in-building penetration, such as a large civil or roading job. Configured and supplied the same way as our Hytera range.
Hearing Protection with Sensear Headsets
The SM1R and SM1P2 headsets suppress harmful site noise while actively letting speech and alarms through, so a worker can hold a radio call and still hear a warning shout without pulling off hearing protection. A genuine safety upgrade over standard earmuffs plus a separate radio.
Solving Dead Zones on Multi-Level and Basement Builds
Cel-Fi GO G41 Building Pack
Concrete floors and structural steel routinely kill mobile signal on multi-storey builds and basement levels. The Cel-Fi GO G41 boosts the existing cellular signal throughout the site, keeping phones and PoC devices usable floor by floor as the build progresses.
Hytera Repeater and Base Station Options
For sites relying on licensed two-way radio rather than cellular, a base station such as the Hytera HR-1062E extends portable coverage across a larger footprint or between buildings, so crews on different levels or blocks stay on the same channel.
Traffic Management and Site Safety
VMS Trailer Hire
Solar-powered variable message sign trailers for real-time traffic and pedestrian messaging around an active site, available to hire for the length of a project.
Lone Worker and Site Safety Monitoring
Where a site has staff working alone or after hours, we can integrate GPS check-ins and man-down alerts alongside your radio fleet so a missed check-in is never treated as routine.
Why Order Your Construction Site Communication System Through MSL
Built for the site, not off a generic shelf
Every radio, headset and booster we supply is matched to your actual site conditions, terrain and building layout, not a one-size-fits-all package.
Programmed before it reaches site
Radios arrive pre-configured to your channel plan and, where relevant, RSM-licensed frequency, so your crew is talking to each other from day one.
On-site support, wherever you're based
We install directly across the Bay of Plenty, Coromandel, Rotorua, TaupΕ and Waikato. Outside that area, we coordinate with trusted installers nationwide or supply fully configured equipment for your own team to fit.
Brand-independent advice
We stock and support multiple radio, booster and headset brands. Our recommendation is based on what suits your site, not on what's easiest for us to sell.
Construction Site Communication FAQs
What's the best two-way radio for a construction site in NZ?
For most sites, a DMR digital portable such as the Hytera HP702 or HP782 gives the best balance of durability, clear audio and channel capacity. Sites needing VHF for licensing or open-ground reasons often use the Motorola R5 instead.
How do we fix dead spots on a multi-level or basement build?
A Cel-Fi GO G41 cellular booster or a Hytera repeater base station, depending on whether your team relies on mobile or licensed radio, typically closes coverage gaps between floors and basement levels.
Can we get hearing protection and a radio in one headset?
Yes. Sensear's SM1R and SM1P2 headsets suppress harmful noise while enhancing speech and alarms, so your crew stay protected and connected without removing hearing protection to talk.
Do our site radios need an RSM licence?
Most commercial private-channel use does. We handle the RSM application and programming as part of supply, so this isn't something you need to sort out separately.
Can you monitor lone workers on our site?
Yes. We can add GPS check-ins and man-down alerts for staff working alone or after hours, integrated alongside your existing radio fleet.
