Implementation scenario
People tracking with LoRaWAN in hazardous workplaces
A proposed workflow for wearable location, assistance requests and coordination, with clear limits for safety-critical operations.

Illustrative implementation scenario. It does not describe a named customer or measured project results.
Picture a maintenance team moving between outdoor equipment, workshops and areas with restricted access. A supervisor needs to know the last reported location and coordinate assistance requests. A wearable connected through LoRaWAN can support this workflow, provided coverage, positioning, privacy and the emergency plan are designed together.
Start with the task and the positioning method
Define the operational purpose: finding a maintenance team, documenting entry to a zone or receiving an assistance request. GNSS can provide outdoor positioning; indoor location may require BLE infrastructure and a supported device. LoRaWAN transports reports but does not, by itself, provide room-level positioning. Agree the required update interval, expected location accuracy, battery checks and how an old position will be marked. Always show the time of the last report so a stale location is not mistaken for a current one.
Pilot the workflow with the workforce
Select representative routes, including difficult radio locations, and involve the people who will wear and supervise the devices. Test device assignment at shift start, reporting, assistance-button handling, battery warnings and the response when a device loses communication. Define access permissions and a proportionate retention period for location data. Tell workers what is collected, why and who can see it; establish applicable privacy and workplace requirements with the responsible teams before deployment.
Benefits depend on the response system
The intended benefit is better coordination and visibility of the last reported position, not a guarantee of rescue or continuous communication. LoRaWAN is not a deterministic life-safety link and must not replace mandatory alarms, protective equipment, rescue procedures or the site emergency plan. For potentially explosive areas, verify the exact device certification, marking and site classification; do not treat a standard wearable as an approved hazardous-area device. Acceptance testing must include lost communication and escalation to the established emergency channel.
Before you start
- Is zone-level location sufficient, and how old may a report be?
- What certification and privacy requirements apply at the site?
- What independent emergency channel remains available if connectivity fails?
