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, characterised in that , in case an event is sensed: • adjusting, by the processor, the logger device to a second higher energy mode and: o 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, o setting the logger device to a transport mode and adjusting the communication frequency with the external data processing device to a second-time frequency, the second-timer frequency being larger than the first-time frequency. • 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, • 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, • detecting if an event is sensed by the sensing device, characterised in that , in case an event is sensed: • adjusting, by the processor, the logger device to a second higher energy mode and: o 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, o setting the logger device to a transport mode and adjusting the communication frequency with the external data processing device to a second-time frequency, the second-timer frequency being larger than the first-time frequency. o 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, o setting the logger device to a transport mode and adjusting the communication frequency with the external data processing device to a second-time frequency, the second-timer frequency being larger than the first-time frequency. <EOS>
