Research

The following are the research grouping in the Department:

Mobile and Wireless Communication Research Group:
Mobile and wireless communication engineering is a fast moving field of telecommunication engineering. It is concerned with the concepts, application, design, development and deployment of mobile communication systems and networks (networks which do not use cable or wire for interconnections). It involves expertise in several inter-related subfields such as physical layer transmission technology (radio engineering, signal processing, synchronization, equalization, channel coding), wireless access technology, radio resource, mobility management and industrial standards.

Data Communication and Network Research Group:
In data communication, data is electronically exchanged between two or more computing or communicating devices along data connections established between them. The data connections, consisting of either cable or wireless media are referred to as data communication or computer networks. Data communication and network engineering is a field in telecommunication engineering that deals with the planning, designing, testing, implementation, operation and evaluation of data communication networks. It involves expertise in network topologies, distributed computation, computer networking, communication software, security issues related to communication etc.

The active research areas currently underway in the Department includes:

1.  Wireless network optimisation
2.  Data communication and
3. 4th generation network deployment
