Introduction to Telecommunications Networks
Course Details
Today’s telecommunications networks are complex mixtures of legacy
technologies, coupled with the latest generation of both fixed and
mobile architectures. This course seeks to provide a grounding to those
people who are new to the telecoms industry, providing them with a
foundation of knowledge which will allow them to explore the
telecommunications ecosystem in greater detail. As such, the course is
all encompassing, providing technical detail on fundamental concepts,
network architectures and finally, today’s services environment.
