Telecommunications networks

Telecommunications networks have become an indispensable tool used by businesses and organizations. However, the telecommunications industry is in the midst of a major transformation, including the migration toward new generation networks, among other changes.

The Master's program is designed to train engineers and other professionals who are called upon to design advanced telecommunications services that rely on Internet technologies.

Students acquire advanced knowledge in networking, mobile telecommunications, multimedia and systems engineering. More and more, multimedia applications are being used by wireless services, and the program takes this new reality into consideration. Students also acquire the skills needed to determine technological requirements for specific companies, and learn to define, justify, plan and complete an implementation project involving an existing technology or applied research or development projects in fields related to telecommunications engineering in a world that is dominated by Internet technologies.

This concentration enables students to carry out simulations and experiments in a variety of technical environments characterized by the presence of multiple Internet telecommunication service providers. This program offers students numerous opportunities to establish contacts with the industrial milieu.

An example of telecommunication engineering

The volume of data circulating through optical networks doubles every year, and telecommunications operators find themselves at constant risk of congestion on their networks. At the same time, cable distributors and newcomers such as Google are developing their own optical networks for insatiable new bandwidth applications. If a solution is not found, new downloading habits involving movies, music and files will push networks to their limits.

This is the type of challenge that Professor Christine Tremblay likes to tackle. Working with her team, she designs new optical network architectures that are capable of responding to huge bandwidth requirements.

Until recently, we had succeeded in increasing the capacity and reach of transmission systems by increasing the number and speed of channels and reducing losses over optical fibres. Today, optical fibre is so pure that attenuation is minimal, and it is possible to transmit 80 channels at 100 Gb/s over a single fibre measuring 1,500 km with no signal regeneration. However, it is very difficult to increase speed or capacity any further using existing transmission techniques.

The solution lies in the use of advanced modulation and signal processing techniques that will make it possible to achieve speeds of 40, 100 and even 500 Gb/s. Thanks to signal intensity and phase modulation and the electronic compensation of dispersion, data can be transmitted at very high speed over a long distance. These technologies are at the heart of the "filterless" optical networks of the emerging generation designed by the team headed by Christine Tremblay.
