Integrating software-defined radios

Abstract In this chapter, we extend the emulator ComNetsEmu used throughout the book by implementing foundational wireless communication applications using Software-Defined Radio (SDR) devices, particularly Universal Software Radio Peripherals (USRPs). After an introduction of SDR and some common implmentations, we provide practical hands-on examples. Through a bridge network located between two Docker containers and the emulator, two basic applications are flashed into the SDR hardware to transfer data using OFDM modulation. This deployment allows us to demonstrate how softwarization leverages the integration of emerging and current technologies applied to communication networks.
