News: For the Academic year 2015/2016, two new master degrees will be offered
The content of this website refers to the degree offered in 2014/2015 degree
Why choosing Telecommunication Engineering?
Do you already hold a basic degree in Communication Engineering and want to know why to continue with an MSc degree? Do you hold a different degree and want to specialize in ICT (Information and Communication Technologies)? If you ended up here by surfing the web you probably already have an answer, but in this page you’ll find out other reasons you weren’t thinking about.
ICT represent one of the backbones of the modern world. In the United States, the California Public Utilities Commission lists among the essential public utility systems water, electricity, fuels, and Telecommunications. Because the role of Telecommunications is not only to enable connectivity (voice and data) between users, but to also enable support services in practically all of the technological fields of modern life. In this page you’ll find some examples, among the less trivial ones, but more exist. Think about it and you’ll find out more of them.
Advanced digital transmission techniques
are crucial in applications such as deep space exploration missions. Satellites and probes operating in such missions are controlled, receive and transmit information arising from measurements and scientific observations at millions of kilometers away. Compared to hearing, these signals have the intensity of a beating of wings at kilometers away. The use of receivers equipped with huge antennas and advanced channel coding techniques
allow to perform these communications in a reliable manner and with an arbitrarily small probability of error. The Mars rover "Curiosity" for example, currently employed in the exploration of Mars, uses for its communications (50 to 380 million kilometers) a coding technique for error correction invented in 1993, the turbo-codes. This coding technique is the same that has been adopted for 3G and 4G cellular communications.
Optical fibers are tiny glass wires, thinner than hair, and allow to transmit Terabit per second over thousands of kilometers. Internet has become pervasive only thanks to optical fibers.
Take for example a successful service as that offered by YouTube: it delivers 6 billion hours of video per month. Considering that on average each movie generates a flow of 500 kilobit per second, about 1018
bytes are transmitted each day, i.e. an Exabyte, equivalent to 45,000 hard disks of 1 Terabyte each. Assuming a uniform distribution over 24 hours, it takes a connection with an aggregate capacity of 4 Terabit per second: the only transmission medium capable of satisfying these requirements is the optical fiber.
Precision agriculture is the discipline that teaches us to manage the
land by taking into account the actual needs of cultivation and soil
characteristics, thus minimizing waste and optimizing resources. It uses
GPS, a global navigation satellite system
based on satellite technologies, such as the future European system Galileo. It requires a remarkable precision, but it offers immense economic and ecological advantages
If you want to become an expert of satellite navigation, you’ll find in
the Communication Engineering degree a course on GNSS (Global
Navigation Satellite Systems), and the opportunity to work in a
laboratory that operates in this field.
Do you have a cell phone in your pocket? You use it to make calls, to
text message, to update your status on Facebook, to read the latest news
about your soccer team, to synchronize your pictures with your home PC,
to play with your friends, and so on. All this is possible because of modern communication networks
which offer ubiquitous access to data and services, and allow us to
reach users in virtually every part of the world, at any time.
Telecommunications allow you to understand and design the networks of today and tomorrow
where billions of users and terminals will be increasingly connected
and close to each other, with applications more and more pervasive and
are based on signal processing and information theory. For examples, when you watch a video on YouTube, compression algorithms reduce the video size, and suitable communication protocols are employed in order to achieve low delay. Image compression algorithms such as JPEG are routinely used onboard any digital camera, but they are also used on satellites for Earth observation equipped with scientific cameras. Matching images in databases
(e.g., Google Goggles) employ visual descriptors and allow you to obtain information regarding the scene you are observing.
