29.10.2020CSG at WiMob20

Eryk Schiller represented the Communication Systems Group (CSG), Department of Informatics (IfI) of the University of Zurich (UZH) at the 16th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob'20) upon October 12-14, 2020. As usual for conferences in 2020, WiMob'20 was organized as a fully virtual event due to COVID-19. A pre-recorded presentation may be accessed here. 

Design and Evaluation of an SDR-based LoRa Cloud Radio Access Network is a paper written as part of the master thesis conducted by Silas Weber and supervised by Eryk Schiller in 2019/2020. Long Range (LoRa) defines a popular modulation scheme based on the chirp spread spectrum technique. It is used in Low Power Wide Area Networks (LP-WANs) for the Internet-of-Things (IoT). This work here designs, specifies, implements, and evaluates a Cloud-Radio Access Network (C-RAN) architecture for LoRa networks, while using Software Defined Radios (SDR) to receive/send radio signals and Docker to virtualize the setup. Furthermore, a software modulator is developed to emit signals on the downlink targeting regular LoRa end-device receivers such as Semtech SX1276 chips.
