A method of operating a wireless logger device

A method of operating a wireless logger device where the logger device is configured to monitor an environmental related parameter of an asset while the asset is transported from an origin location to a destination location, where the logger device comprises:

• a power source for powering the logger device,
• a storage medium,
• a sensing device for sensing an environmental related parameter of the asset,
• a communication module, a processor for operating the power source, the storage medium, the sensing device and the communication module,
• the method comprising:
• setting, by the processor, the logger device in a first low-power mode where the environmental related parameter is measured by the sensing device and where the resulting environmental related data is stored in the storage medium, where in the low-power mode the communication module communicates with an external data processing device with at least one first-time frequency by means of temporarily setting the logger device to a first higher-energy mode during the communication with the external data processing device,
• wherein the method further comprises:
• detecting if an event is sensed by the sensing device, where in case an event is sensed:
• adjusting, by the processor, the logger device to a second higher energy mode and:
• checking if the logger device is to be set to a transport mode, where in case the checking results in that the logger device is to be set to a transport mode,
• setting the logger device to a transport mode and adjusting a communication frequency with the external data processing device to a second-time frequency, the second-time frequency being larger than the first-time frequency.
