Networked Systems and Smart Infrastructure
A sensor detects an event, a radio network carries the message and an application responds. FILA studies this processing chain in wireless sensor networks, IoT communication and distributed control. The research question is how individual components become a dependable system.
In low-power wide-area networks (LPWAN), range, transmission time and message size are connected. The 2023 LoRaWAN study combines laboratory and free-field measurements with moving end devices. In the free-field test, the configuration using spreading factor 12 and 14 dBm transmission power reached up to 10,950 metres. This result belongs to the reported conditions; terrain and the radio environment matter.
Motion was tested at 20, 50 and 100 km/h. At 100 km/h and 5 dBm, connection problems occurred; higher transmission power improved communication in that experiment. The finding makes the trade-off tangible: radio settings must fit the application’s motion, range and energy needs. Explore the LoRaWAN setup, measurement plots and limits.
INPAKT examines the energy cost of such communication. SmartLighting connects motion detection and message exchange with control of neighbouring lamps. Its historical Bernburg-Strenzfeld installation illustrates the interaction between sensing, radio communication and energy supply.
Another example is the 2025 publication on maritime emergency communication, which examines a laboratory prototype combining speech and button inputs, GPS information and LoRaWAN messages. The paper describes the prototype and its evaluation. These studies suggest concrete discussion questions: what information must travel, what energy demand is acceptable, and how much delay can the application tolerate?
