The technology, known as SINTRA, is provided by German startup Smartly Solutions. Altrad is attaching Bluetooth Low Energy (BLE) beacons to crates in which scaffolding products are stored and shipped, with beacon-reading smartphones mounted on walls and gates, and beacon-reading tablets or mobile phones in workers' hands. A SINTRA app running on the mounted reading devices uses the received signal strength indicator (RSSI) to approximate each tag's location within the facility in real time. Workers can then use their tablets, with a separate SINTRA app to locate identify crates.
