  This report summarizes some of the material that was presented by the author
during the 2015 Les Houches Summerschool on "Random Matrices and Stochastic
Processes". In these Lectures, various applications of Random Matrix Theory in
modern telecommunications are reviewed. The aim is to introduce the Physics
community to a number of relevant problems that can be analyzed using such
tools, while at the same time briefly describing the way these methods are
applied. More specifically, two applications on wireless communications and two
on optical communications are presented.
