Researches at Communications And Networking Engineering Lab (CANE Lab) focuses in the three areas: Secure networking with quantum information system, the 5G mobile network solutions with content-aware mobile/wireless networking, and 5G front and backhaul networking with flexible and reliable SDN cloud networking solutions.

Quantum information researches focus on the development of novel but commercially applicable technology for the quantum cryptography to share critical information with a remote node unconditionally securely. As a long-term research goal, the research and development of the quantum information system has been initiated.
