You need to closely monitor multiple parameters, such as rail temperature, in near real-time, on a massive and dynamic structure with a network of thousands of heterogeneous devices.

You need to perform long-range monitoring without antennas, hazards or constraints on the track devices.

You need to monitor long rail tracks covering remote distances.

You need to manage the impact of changing environmental and weather conditions (i.e. vegetation that may affect line of sight, rain, dust etc.).

You work with remote power sources for monitoring equipment.

You need to conduct costly and operationally disruptive track maintenance that requires manpower
