RTLS-Enabled Bidirectional Alert System for Proximity Risk Mitigation in Tunnel Environments by Fatima Afzal, Farhad Ullah Khan, Ayaz Ahmad Khan, Ruchini Jayasinghe, Numan Khan

“…This study addresses a critical gap in real-time, bidirectional proximity monitoring by developing and validating a prototype early-warning system that integrates real-time location systems (RTLS) with long-range (LoRa) wireless communication and ultra-wideband (UWB) positioning. The system comprises Arduino nano microcontrollers, organic light-emitting diode (OLED) displays, and piezo buzzers to detect and signal proximity breaches between workers and equipment. …”
