Challenge / Goal

More and more cities have started adopting energy efficient LED street lighting, which offers substantial (up to 50%) savings on energy consumption. Milan is exploring how a range of sensors and services can be added to lamp posts to transform them into a smart infrastructure for the city, demonstrating how smart technology can add value to people’s lives. The goal was to improve the efficiency of energy use in public lighting. 


Milan has already replaced all street lights with LED technology, saving 50% of energy consumption and reducing CO2 emissions.

Smart lamp posts became the enabling infrastructure for several new services: Wi-Fi antennas, environmental monitoring (such as air quality, temperature, humidity, rain and water level, atmospheric pressure, noise), transport monitoring (such as monitoring traffic flow and speed of vehicles and flow of pedestrians, discouraging double parked cars system etc.). 

The telecommunication infrastructure will use a LoRaWAN protocol, which enables long-range wireless coverage for the Internet of Things (IoT) paradigm. By installing data concentrators for collecting data from field sensors and interfacing the same concentrators to the network server, cities have a network for new services.
