Industrial site where lone workers rely on connected safety devices

Connectivity you can trust for lone worker devices

When someone works alone, the alarm has to get through. Com4 keeps lone worker devices and personal alarms connected with multi-network, data-based alarm transmission.

Built for devices that can't afford to go offline

Lone worker badges, personal alarms and geofenced safety units are only as good as their connection. A Com4 SIM can use several mobile networks in each country, so a device that loses one network can move to another. Alarms, positions and status updates reach your monitoring platform or alarm receiving centre as data.

Lone worker devices are one part of connected safety. For CCTV, access control and alarms, see IoT connectivity for security.

How it works

Data-based alarm transmission

Com4 supports data-based alarm transmission for lone worker devices. Alarm events, GPS positions, check-ins, no-movement alerts and battery status are sent over LTE-M, NB-IoT, 4G or 5G to your platform.

  • SIMs ship pre-activated, ready for production and deployment
  • Access to multiple networks per country for higher availability
  • Private APN and secure routing straight to your platform
  • Every SIM visible and controllable in Polaris, our connectivity management platform
  • Physical SIM or eSIM, to suit your device design

Com4 can help you build reliable lone worker solutions

Performance

Resilient coverage

Multi-network SIMs reduce the risk of a device being stuck on one weak or failing network, indoors, outdoors and in remote areas.

Alarm

Alarms delivered as data

Alarm events travel as data messages over LTE-M, NB-IoT, 4G or 5G, with low power use that keeps devices running longer between charges.

User

Location and geofencing

Send position updates and geofence events so the monitoring team always knows where help is needed.

Customer portal

Central management

See status, data usage and connection history for every device in Polaris, and act on issues before a worker is affected.

Security

Secure by design

Private APN and encrypted connections keep personal safety data away from the public internet.
