LoRaWAN
LoRaWAN, an abbreviation for "Long Range Wide Area Network", is a protocol that aims to connect battery-powered devices (nodes) in regional, national or global networks to the internet. Because LoRaWAN uses lower frequencies than, for example, WLAN, it enables data transmission over longer distances and can therefore be very useful where WLAN infrastructure is poor. The system requires interaction between battery-powered nodes that collect and send data and a gateway that intercepts this data from the nodes and processes it accordingly.
Even though Johannes started this project in Germany, he was able to share his knowledge with students in Togo and work together on its applications. Some examples are the monitoring of renewable energy systems such as a solar concentrator or green roofs. Furthermore, this project will be used in connection with the future Center of Renewable Energy Systems (CenRES) in Kara, Togo.
