General Info

Communication Networks Laboratory (CNL) was founded in 1994 as a research and graduate education unit within the Telecommunications and Signal Processing division of the Department of Informatics and Telecommunications of the University of Athens, focusing on R&D in the area of Communication Networks. During the past years, the CNL has demonstrated an active involvement in the areas of wireless/mobile networks and services, broadband communications, and networked multimedia communications. Through its participation in numerous EU and national projects, the staff of the Laboratory has acquired considerable experience in the area of wireless/mobile networks (especially in UMTS, Wireless LANs, Wireless Internet, Reconfigurable Networks and Services, Location Based Services) and networked multimedia traffic management and applications.

CNL cooperates with the Network Operations and Management Center of the University of Athens in the deployment and management of the high-speed network of the University of Athens and advanced services, serving an academic community of 80.000 students, faculty and staff.
