Abstract

Much effort has been put into developing algorithms for locating pipe bursts in freshwater networks. Such algorithms typically require a precision time-synchronization of all participating sensor nodes. The performance and efficiency of tight clock synchronization using Narrowband IoT (NB-IoT) has thereby rarely been characterized. The present work addresses this research gap by evaluating time-synchro-nization using NB-IoT enabled sensors. Multiple experiments showed that a relative time precision of 10 ms across the network compared to GNSS can be expected using a custom approach.
