What is a connected worker?

Every industrial plant can tell you, at any moment, where each piece of critical equipment, each vehicle, and each load is. A few years ago, industry started asking a different question: what about the people? When someone needs help in a remote corner of the site, how long does it take for the control room to find out what happened, locate the person who called, and send the right response? The connected worker concept was created to shorten that wait.

Defining the connected worker

A connected worker is a field worker integrated into the company’s digital processes. That integration happens in three layers that work together: a wearable device that stays with the worker through the daily routine, a communications network that covers the entire plant, and a platform that turns field data into alerts, evidence, and decisions.

The central idea is that workers don’t change the way they work. They wear the device like an ID badge and work their shift as usual. What changes is the operation, which can now see what used to be invisible: where the crews are, who has entered each area, and who needs help right now.

Why industry is adopting it

Three reasons come up in almost every connected worker project:

• Industrial safety: Risk management stops relying on procedures alone and starts drawing on real-time data. Alerts when someone approaches a restricted area, along with presence records, help prevent incidents before they happen.
• Emergency response: An emergency button on the worker’s chest shortens the path from incident to help. The control room receives the call with the exact location and dispatches the right response, without depending on a radio or on witnesses.
• Operational visibility: Knowing how many people are in each area, on each shift, changes how you plan maintenance turnarounds, handle logistics for a large headcount, and respond to anything out of the ordinary.

The role of digital PPE

Digital PPE is the entry point to connected worker technology. At PHYGITALL, it takes the form of a smart badge, the Smartbadge, with an emergency button, real-time location, and direct communication with people in the field. A variant, the Smartbadge with Ex certification, also takes that protection into hazardous (classified) areas, where ordinary electronics cannot operate. Its Ex certification is issued under INMETRO (Brazil’s certification body), and the device has type approval from ANATEL (Brazil’s telecom regulator).

Privacy is part of the design: the Smartbadge does not record audio or video. It logs what matters for safety, such as location and emergency calls, and nothing beyond that.

Why a private network matters

An industrial plant is a difficult environment for communications. Metal structures, sprawling layouts, and cellular dead zones knock out any solution that depends on public networks. That’s why the most mature connected worker operations run on a private network. PHYGITALL builds dedicated LoRaWAN networks that cover the entire plant, even where cell signal doesn’t reach, and keep running independently of public infrastructure.

How a deployment begins

A connected worker project starts with the problem the operation needs to solve. The typical steps are:

1. Assessment: Understand the operation, the highest-risk areas, and the existing emergency procedures.
2. Pilot: Deploy in a defined area with a set group of workers to measure results in the field.
3. Scale-up: Expand network coverage and the number of devices based on the pilot results.
4. Integration: Connect the data to the company’s safety processes, such as the Safeline response workflows.

Starting with one use case and expanding later is the natural path: safety and productivity come from the same field data.

The scale it has already reached in Brazil

Brazil’s largest connected worker deployment links more than 5,000 workers at Petrobras in Itaboraí using PHYGITALL technology: a large headcount, hazardous areas, and the day-to-day reality of one of the world’s largest industrial companies.
