Mobile radio communications

What you will learn:

You'll learn how radio channels are provided, understand the modulation and multiple access schemes used across different mobile generations from 2G through to 5G, and discover how the RAN handles the challenges of interference and variable channel quality. The course also discusses the measures taken to ensure the security of mobile communications.

 

By the end of this course you will be able to:

• define the air interface and explain how a radio wave is affected by its environment.
• explain the terms loss, gain, cochannel and adjacent channel interference, and delay.
• describe types of fading, their causes and methods used to reduce their effects.
• describe and compare the methods of providing access to and from a basestation by many mobiles as employed by 2G, 3G, 4G and 5G systems.
• describe the factors that determine the maximum capacity and data transfer rates of a mobile radio access network
• describe frequency bands in use, frequency allocation methods and considerations affecting the choice of frequency band for mobile communications.
• describe the evolution of mobile systems from 2G to 5G to meet the demand for faster, more reliable and secure data services.
• describe methods of maximising data transfer rates including use of MIMO antennae and carrier aggregation.
• describe the need for, and methods of implementing, secure communications over the air interface.

 

Course prerequisites:

You will get the most out of this course if you already have a basic understanding of the operation of a cellular mobile system and the role of the various elements of a mobile network. It is recommended that the PTT course "Introduction to mobile systems" is studied before attempting this course.

 

Approximate study time: 6 hours
