Long-range, low-power communications for IoT: the LoRa technology

Speaker: Daniel Zucchetto, Date: 4th of December 2015, Time: 13:30, Room: 201 (DEI/A)

Abstract. The basis of a IoT system is to be found on the physical connection between the devices in the IoT network. Most of the connections between things have to be done using wireless technologies, since the number of devices to connect is usually large and, in many scenarios, they need to be mobile,  Continue Reading…
