Networks are of an increasing importance in commerce, education and culture and absorb an ever-increasing share of the national budget as there is an expectation that we will be able to connect to any online environment through a medium of our choice at any location. This course will provide students with the knowledge to model protocols and standards used in networks and wireless communication systems and how to ensure continuity of service. This course will equip students with the insight needed for a career in communications technology.

This course focuses on wireless communication technology as used in mobile phone networks, including 4G and 5G and the series of standards associated with wireless local area networks. Students will also investigate the quality of service in the Internet with a focus on the DiffServ standard and use a graphical interface to gain an understanding of these topics. Optical communications are investigated in terms of the capacity of optical fibres and associated switching technologies.

On successful completion of this course students should be:

1. Compute the capacity of wireless and optical systems according to the Shannon formula;
2. Formulate distortion and noise in wireless communication systems and the methods used to overcome it;
3. Compare and contrast interference between co-located wireless communication systems and different methods used to overcome it;
4. Simulate or model and analyse the throughput, performance, and fairness of wireless, optical and tcp/ip systems;
5. Make appropriate choices of configuration of wireless security;
6. Evaluate networks which carry multiple traffic types with different quality of service requirements and the methods used to cater for them;
7. Analyse the use of wave-division multiplexing and switching in optical systems and how it can be used to deliver increasing demand for services in future.
