The Christian Doppler Laboratory for Wireless Technologies for Sustainable Mobility focuses on fundamental questions related to vehicular, cellular and short-range communication: connectivity, reliability, and availability. By a tight coupling of experimental work and design, we avoid simplistic assumptions on the communication channel statistics. We evaluate our designs on testbeds comprising real-world wireless communication environments. Thereby, we validate the devised algorithms in-situ. Key performance indicators for such wireless technologies are the reliability, the capability to meet strict deadlines, and coverage which we aim to achieve through multiple antenna transmission and reception. Our research plan consists of four modules: Vehicular Connectivity (Module 1 with Kapsch TrafficCom AG), Smart Tags for Sensor Nets (Module 2 with Infineon Technologies Austria AG), Mobile Communications Evolution (Module 3 with A1 Telekom Austria AG and Kathrein Austria GmbH), and Nearfield Power Efficiency (Module 4 with NXP Semiconductors Austria GmbH). The research in Module 1 focuses on reliable real-time wireless technologies in time¿variant communication scenarios for safety-related applications. In Module 2, we investigate advanced transmission techniques for low energy consumption tags and aim at increasing the robustness of transmission in industrial environments. In Module 3, we measure and optimize multiuser throughput of multi-antenna transmission under delay constraints on the wireless channel and the novel inter-base station co-operative signaling. Further, we evaluate the potential gain from interference management for orthogonal frequency division multiple access (OFDMA). Efficient energy and data transmission for contactless identification is the central challenge in Modul 4. In early 2013, a new fifth module was started with the partners Propagation Ideas and Solutions GmbH (PIDSO) und BMW Forschung und Technik GmbH.
