Networks inside IoT applications can be very complicated, merging several different standards in order to achieve the common communication objective. This chapter presents the main reference communication scenarios and architectures, as well as the primary standards behind them. To better describe network standards, the well-known ISO/OSI model is adopted as reference and the basic network terminology is introduced. We present several widespread standards such as Bluetooth, IEEE~802.15.4-based technologies, LoRaWAN, Sigfox, and, among cellular standards, NB-IoT and LTE-M. Then application-level technologies are discussed. Finally, we discuss the aspects to be considered in the design of the communication part of IoT applications, including localization aspects.

Abstract
Networks inside IoT applications can be very complicated, merging several different standards in order to achieve the common communication objective. This chapter presents the main reference communication scenarios and architectures, as well as the primary standards behind them. To better describe network standards, the well-known ISO/OSI model is adopted as reference and the basic network terminology is introduced. We present several widespread standards such as Bluetooth, IEEE~802.15.4-based technologies, LoRaWAN, Sigfox, and, among cellular standards, NB-IoT and LTE-M. Then application-level technologies are discussed. Finally, we discuss the aspects to be considered in the design of the communication part of IoT applications, including localization aspects.
