Telecommunication Network

Training goals

This course aims at providing in a clear and cutting-edge manner the basic notions on telecommunication networks, with a special emphasis on computer networks and the TCP/IP protocol suite.


A course covering the basics of Communication Theory and a probability theory course is recommended.
