Sensing Backhaul refers to the communication link used in wireless sensor networks to transmit data collected by sensors to a central processing unit or data sink. The backhaul enables the aggregation and analysis of sensor data at a centralized location. Sensing backhaul is commonly used in applications such as environmental monitoring, industrial automation, and smart cities where data from distributed sensors needs to be collected and processed centrally.


Perimeter Intrusion Detection with Rayleigh Enhanced Fiber Using Telecom Cables as Sensing Backhaul

We report field test results of facility perimeter intrusion detection with distributed-fiber-sensing technology and backscattering-enhanced-fiber by using deployed telecom fiber cables as sensing backhaul. Various intrusive activities, such as walking/jumping at >100ft distance, are detected.
