Context

With more than 100 billion of connected objects estimated in 2020, the Internet of Things is considered now as a key element of the numerical evolution. The technology connecting the smart objects of the IoT is extremely varied: some objects are connected through a local access point using WiFi, Zigbee or Bluetooth and rely on the connectivity of the access point to access a wider network; others rely on a communication infrastructure to convey the information and are often referred as Low Power Wide Area (LPWA) networking technologies. These LPWAN technologies define a new air interface that gives a low power connectivity alternative to cellular systems and are either exploited under unlicensed band (such as Sigfox, LoRa) or licensed band (such as LTE-Cat M and NarrowBand IoT). This course introduces the general architecture of the IoT network of as well as the radio technologies that connect these objects.
