Some details
An Australian provider of location-based solutions for enterprise needed an energy-efficient geolocation system for one of their clients in the mining industry. They needed a solution that would allow for locating and tracking people in underground mines.
Our team at Integra Sources created a special gateway device that is attached to the miner',s belt. It captures wireless signals broadcasted by Bluetooth beacons that
are installed around the area being monitored. Each signal has a different power depending on the distance of the beacon to the gateway device. When the gateway device captures a signal, it transfers its identifier via WiFi, so we know where exactly under the ground the gateway device is located at any given moment.On the surface, the gateway device uses GPS, WiFi, and 3G to locate signals.

- nRF52832 with BLE 5.0 and Cortex-M4F core
- FreeRTOS - Microsoft Visual Studio
- SIM5360 module for 3G &, Wi-Fi
