Wireless and Optical communications technologies underpin many of the services and devices that are a part of modern society from the ubiquitous smart phone that is wirelessly connected to the optical communications network through to photonic and wireless sensors that enable devices such as optical mice and RF identity cards. The communication networks that provide internet connectivity both to homes and mobile devices rely on optical, wireless and wired networks for the transport of data. Satellite systems for content distribution, mobile communication and global positioning also utilize wireless communication technologies
The demand for increasing bandwidth and coverage to support new and enhanced services in both fixed and mobile locations requires engineers with a good understanding of both wireless and photonic communication technologies, ranging from device concepts to system design and project management. A unique feature of the course is the way it unites concepts across both wireless and optical communication to give students a better overall grasp of the technical challenges they will face in engineering the rapid development of the next generation communications infrastructure. There is exceptionally strong industry demand for engineers with this skill base and a clear shortage of supply.
This programme is intended to contribute to meeting the demand by providing a full-time MSc course for graduates in electronic engineering and physics to train them for work in this industry and by offering modules which the industry can use for specialised training of existing employees. The course provides students with a strong understanding of the underlying physics, design principles and operation of wireless and optical systems and as such is an ideal stepping stone for those looking to go onto studying for a PhD
The MSc in Wireless and Optical Communications provides training in the key technologies required for the physical layer of photonic, wireless and wired communications systems and other applications of this technology ranging from THz imaging to Radar systems. The programme encompasses the complete system design from device physics through to subsystems and finally to complete physical layer system implementations.
The programme structure, shown to the right, consists of five core modules, taught in the first term, that are designed to provide the necessary background in communications engineering ranging from network aspects through to physical layer implementation of both wireless and optical communication systems. These modules are all taught in one week blocks during the first term.
The optional modules, taught in the second term, are designed to build on the knowledge gained in the compulsory modules and provide in depth coverage and specialist knowledge as well as future technology directions and the latest research results in key areas in wireless and optical communication systems. You choose three modules which allows for specialisation in a particular aspect of either wireless or optical communications or choose the areas that are of most interest.
All of the course lecturers carry out leading research in the subjects they are teaching. Modules are taught in 4 day blocks from Monday to Thursday in single week (10am to 5pm), followed a few weeks later by a half day tutorial and then an examination the following week or the submission of an assignment.
The research project and dissertation forms a major component of the MSc and is carried out from January through till the end of August. The projects may be carried out either within a UCL research group or industry. In many cases the work carried out by the student leads to advances in the department’s research output and publications in addition to giving the student good experience of research work.
This work is also supported via a compulsory professional development module that develops the necessary project management, research and dissertation writing skills to successfully complete the research project.
