Welcome to the Telecommunication Networks Group (TKN) at the School of Electrical Engineering and Computer Science, TU Berlin. TKN is coordinated by Falko Dressler. TKN is also part of the CCS Labs. The acronym CCS stands for Computer and Communication Systems. Our research objectives include adaptive wireless networking (sub-6GHz, mmWave, visible light, molecular communication) and wireless-based sensing with applications in ad hoc and sensor networks, the Internet of Things, and Cyber-Physical Systems. Our current projects focus on novel and innovative concepts for 5G/6G communication systems, digital smart cities of tomorrow, and vehicular applications, emphasizing on communication technologies and cooperative assistance systems.
