The course aims to give students an in-depth introduction to the latest networking technologies for mobile and wireless communications and a complex knowledge of the complete architecture of each relevant family of technologies. After an introduction and an adequately positioned evolutionary/historical retrospective, the course will approach the available solutions through the most relevant use cases. To this end, the network use cases that can be delineated by, among others, Industry 4.0, mission-critical scenarios, cooperative intelligent transport systems services, and resource-critical applications will be presented and used to define the requirements for supporting network environments. Along the novel use cases and requirements, the advanced technologies of IEEE 802.11 (11ac, 11ah, 11af, 11r, 11p, 11bd...) are first discussed, followed by the 60GHz millimeter-wave multi-gigabit wireless networks (WiGig, WiHD). 4G and 5G representatives of mobile cellular infrastructures will be presented in the next module, with a focus on 5G NR standards, the latest spectrum usage technologies (e.g., 3D beamforming, DAS, LAA), energy efficient approaches (DTX, antenna muting), application specific developments (IoT, streaming, V2X), and 5G core network technologies (SDN, NFV, slicing, MEC, etc.), with a look at beyond 5G and 6G development directions. Moving on to vehicular ad-hoc networks (VANET) systems, the course will focus on the primary architectural considerations, with a description of the most common standardized solutions currently in use (ITS-G5/DSRC, WAVE), also covering the specifics of 4G and 5G cellular V2X, as well as hybrid V2X communication, and finally the current relationship between the IP and V2X worlds (IPWAVE and its issues). As a last module, specific technologies for IoT will be presented, also characterizing the complete protocol layer structure and corresponding complete architectures, from the application layer to radio solutions (e.g., MQTT, CoAP, 6LowPAN, 6Lo, RPL, CARP, ZigBee, LoRa, Sigfox, NB-IoT), with appropriately selected protocol descriptions and efficient backward/forward references to Wi-Fi and mobile cellular systems.
