Broadly defined communication technology includes theory, technology, design, and construction of equipment in connection with transfer and processing of signals and information. For strategic reasons the Department has, however, confined its research domain to wireless communication and related subjects. The Department carries out research in the following fields of activity:

* Antennas and Propagation
* Cellular Systems
* Digital Communications
* GPS
* RF Integrated Systems and Circuits
* Speech and Multimedia Communications
* Wireless Networks

Teaching
The Department is involved in teaching in the Bachelor of Science and Master of Science educations within telecommunications, informatics, communications network and signal processing. Within these areas, the Department offers a series of specializations conducted in English:

* Applied Signal Processing and Implementation
* GPS Technology
* Mobile Communication
* RF Integrated Systems and Circuits
* Signal and Information Processing for Communications (SIPCom)

As part of the internationalization efforts by the University and the Department the specializations are offered to both Danish and foreign bachelor-degree students with the purpose of getting a Master of Science degree.
Furthermore, the Department is involved in the continuing education programs ELITE and Lifelong Learning.
