Low Power Wide Area Network (LPWAN)

Schematic representation of a Low Power Wide Area Network (source: https://www.researchgate.net/publication/335442047_A_Survey_on_LoRa_Networking_Research_Problems_Current_Solutions_and_Open_Issues/figures?lo=1, retrieved on 23.12.2019)

Function: An LPWAN consists of terminals (e.g. sensors) that communicate with a gateway (interface) via license-free frequencies (Europe: 863 - 870 megahertz) of the radio spectrum. The transmission takes place by means of a network protocol, which is characterized by high ranges (-10km) and low energy consumption. The gateway bundles the information from the end devices and then passes it on to a network server via a mobile radio network (WLAN, 2/3/4/5G etc.) or fixed network connection (possible applications: Smart Parking, Smart Waste and Air Quality Measurement).

Advantages: High ranges (even penetration of massive concrete structures is possible), low power consumption and low operating costs

Examples: Zurich, Basel, Lucerne
