Where must radios work?
Identify the operational zones, buildings, floors, yards and external areas where users need dependable communication.
Radio coverage survey · DMR system design
Find the coverage gaps before choosing the radio system.
A radio coverage survey helps define where reliable two-way radio communication is required across a site and where buildings, distance, construction materials or operational areas may create weak coverage. The result is a clearer basis for deciding whether direct radio-to-radio operation is enough or whether repeaters and supporting infrastructure should be considered.
What the survey should answer
Design around the real site, not a coverage assumption.
Find likely coverage constraints
Site layout, reinforced structures, basements, plant rooms, distance and elevation can all affect radio performance.
Decide whether repeaters are justified
Where direct communication is not sufficient, the survey can inform whether repeater or antenna infrastructure should be evaluated.
Survey to system design
Coverage is only one part of choosing DMR or PoC.
| Environment | What to assess | Possible direction |
|---|---|---|
| Single compact site | Building construction, indoor/outdoor zones and direct radio performance | Direct DMR may be sufficient where coverage is proven. |
| Large or complex site | Dead zones, vertical coverage, remote buildings and critical operational areas | Engineered DMR infrastructure may be appropriate. |
| Distributed teams | Wide-area operation, cellular/Wi-Fi availability and dispatch requirements | PTToC may be a better fit than extending a local radio network. |
| Mixed requirement | Local resilience plus wide-area coordination | A hybrid design may be worth evaluating. |
Complex sites
Bring the site plan, user groups and critical communication areas.
We can use those requirements to define the survey scope and the radio architecture that should be evaluated.
Radio coverage survey
A site survey turns “the radios don't work here” into a measurable coverage problem.
A radio coverage survey assesses where users need communications, where coverage degrades and which building, terrain or operational factors affect the system. The outcome can then inform handset choice, repeater design, antenna location or whether cellular push-to-talk should be considered for part of the operation.
Map the user journey
Coverage needs to be checked where people actually work: plant rooms, basements, stairwells, external areas, compounds and changing work zones.
Test the architecture
The survey can distinguish a handset problem from an infrastructure problem and identify where repeaters or antennas may be justified.
Choose DMR or PTToC rationally
Local radio and cellular push-to-talk solve different coverage problems. Survey evidence helps avoid choosing by product preference alone.
After the survey, review the available professional two-way radio systems against the measured coverage requirement.
