LoRaWAN with deZem
Receive signals from previously unreachable locations and easily read widely distributed sensors - all wirelessly! LoRaWAN enables wireless data transmission of measurements, control commands, and more over long distances with extremely low energy consumption.
The small data packets are always securely end-to-end encrypted. Thick walls pose no obstacle, and even hard-to-reach locations can be connected wirelessly. Installing the sensors is quick and easy: Place sensor, power on - done!
The LoRaWAN antenna also acts as a gateway; it receives the data from all sensors in range and sends them to an IoT platform e.g. deZem.io From there, the data is sent on to deZem platform for storage and analysis.
Fields of application
LoRaWAN triggers a rethink of old as well as entirely new fields of application in:
- Facility management
- Cable-free and battery-free energy data acquisition
- Property monitoring, e.g. parking lots
- Remote reading of meters reading, e.g. on extensive industrial sites
- Monitoring of widely distributed wells and shafts
- Transport monitoring
- Tracker
- Lumber yards in the woods
- Weather sensors

LoRaWAN infrastructure - public or private?
Antennas in the field transmit the sensor data to an IoT (Internet of Things) platform. The IoT platform serves to manage the LoRaWAN infrastructure, administer the sensors and, if necessary, pre-process the sensor data. For permanent storage and analysis, the data are sent from there to the deZem data platform or other platforms. Regarding the IoT platforms there is a difference between private and public IoT platforms:
Private IoT platform
deZem.io is our private IoT platform. It is hosted on servers operated by deZem in Germany. The availability of deZem.io is assured without dependency on a public infrastructure.
Public IoT platforms
Alternatively, public IoT platforms, e.g. The Things Network, can be used to send LoRaWAN sensor data to the desired target addresses, e.g. to the deZem platform. However, no availability guarantee is given and the provider limits transmission time available per day.
