Construction Site Radio Systems — Wide-Area DMR for Multi-Phase Sites
Cover a site that keeps changing: cranes, laydown yards, haul roads and temporary offices, with repeaters that can move as the project does.
Values come from the linked product records and their manufacturer documents; unpublished fields are left blank, not inferred.
Why Standard Radios Fail Here
The site moves
Phase changes relocate the work front. Plan repeater positions and antenna height so the system can be re-sited without a redesign.
Noise and dust
Specify audio accessories and ingress protection for the actual conditions, not for an office environment.
Subcontractor groups
Give each subcontractor its own talk group so site-wide announcements do not drown the channel they work on.
Power and backhaul
Temporary power is unreliable. Decide whether the repeater needs battery backup or a generator feed before ordering.

Site Types, Hazard Classification and Approvals
Where these terminals are deployed, how the area is classified, and which approval the destination regulator asks for.
Typical sites
- Multi-phase construction sites
- Haul roads and laydown yards
- Temporary site offices and workshops
Hazard classification
- Dust and water exposure; specify ingress protection for the actual conditions
- High ambient noise, requiring audio accessories
- Temporary power at repeater positions
Approvals by destination
- Licensed land mobile band — Destination countryA site network normally needs a licensed frequency assignment. Confirm who holds it before specifying repeaters.
- CE / RED — European UnionApplies to the terminal; the licence itself is a separate national process.
- Import documentation — Destination countrySome markets ask for a declaration of conformity at import. State the destination so the paperwork is planned, not improvised.
Documentation is supplied for the model ordered; a generic certificate is never substituted. If your tender names a scheme not listed here, send the destination and the standard and we will confirm what applies.
Deployment Planning Checklist
Treat repeater placement as temporary infrastructure: document antenna height, cable route and power source so the same hardware can be lifted to the next phase. Programme all groups before shipment so commissioning on site is a power-up and radio check, not a programming session.
Deep Technical FAQ
One repeater or several?
It follows from the site geometry and the coverage target, not from headcount. Send a site plan with distances and the areas that must be covered, and the repeater count follows from that.
Can we rent instead of buying?
This site supplies equipment for purchase. If the project is short, tell us the duration and we will quote the package that makes sense to own, including what can be reused on the next site.
Will radios survive on site?
Choose the ingress protection and accessory set for the environment you actually have. State the dust and water exposure in the inquiry; the model choice follows from it.
What should be in a construction RFQ?
Site plan, phase timeline, coverage target, user count by subcontractor, power availability at repeater positions, destination and required delivery date.
Need the network planned, not just the radios?
For a project in this sector we also work out the radio and repeater quantities, the coverage layout and the full BOM, then supply it pre-programmed.
