Keep field crews and lone workers reachable everywhere on site.
Public cell coverage is spotty across big industrial sites, and Wi-Fi doesn't follow the worker. A private network carries push-to-talk, alerts and location on devices you control.
What it looks like day to day.
A typical scenario based on the environments we work in, not a specific customer.
- Workers carry a radio, a phone and a separate work device
- Dead spots where a lone worker can't call for help
- Alerts and location updates arrive late or not at all
- Radios and phones don't talk to each other
Safety can't depend on where you're standing.
Large sites mix outdoor units, steel structures and remote corners. A private cellular network gives approved devices consistent coverage, priority for safety traffic, and a network the site owns.
How we fix it.
Private LTE/5G is a cellular network your organization controls. A few radios cover large areas, devices use SIMs you issue, and handoffs are built for movement.
Map where people work
Including remote areas, structures and lone-worker zones.
Plan site-wide coverage
Private cells for indoor and outdoor work areas.
Choose the devices
Rugged phones or wearables with push-to-talk and alerts, on your SIMs.
Test the critical spots
Verify calls and alerts where they matter most.
Designs start from your site plans and how things move. We survey on site when the environment calls for it.
What's different after.
One device
Push-to-talk, apps and alerts together.
Fewer dead zones
Coverage planned for where people actually work.
Faster response
Alerts and location arrive when they're needed.
Where this works, and where something else fits better.
We recommend what solves the problem, even when it's a different solution.
A good fit for
- Refineries, chemical and manufacturing plants
- Mines, utilities and large industrial sites
- Sites with lone-worker programs
Something else may fit better
- Code-required emergency responder radio is a separate system: see commercial vs. public-safety coverage Read: Does one DAS cover both code and cell service? →

The design decisions, the end-to-end path and how the result is tested.
Push-to-talk, lone-worker alerting, location, work orders, and emergency calling have different consequences and may require different fallback systems.
Design decisions
| Design decision | What we need to understand | How we engineer it |
|---|---|---|
| Service role | Document which communications are operational, safety-related, or code-required. | Assign the correct network, owner, availability, and fallback to each function. |
| Worker route | Map indoor, outdoor, elevated, remote, and shielded locations. | Design cells and antennas around the full shift route. |
| Device model | Verify ruggedness, bands, SIM, PTT client, battery, audio, and PPE use. | Test the worn device in real working conditions. |

Public-safety responder radio coverage must be evaluated separately under the applicable authority and code. A private worker network does not replace it by assumption.
How the result is tested
- Route test Walk every representative shift route with the worn production device.
- Audio test Verify intelligibility with PPE, noise, and expected speaker accessories.
- Alert test Trigger, route, acknowledge, escalate, and close a lone-worker event.
- Location test Measure useful accuracy and update behavior where it affects response.
- Failure test Exercise device, battery, cell, core, application, and backhaul failures.
- Boundary test Document where private operational service ends and public-safety systems apply.
