Mobile radio communications

Target audience:

This online course is designed for those who are, or intend to be, involved in the planning, installation, provisioning or maintenance of mobile systems.

 

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.

 

Course objectives:
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.
