What does this mean?
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.
It is suggested this course is studied with its companion course "Mobile radio communications" as preparation for the other PTT courses covering mobile networks.
Course prerequisites:
You will get the most out of this course if you already have a basic understanding of the principles, capabilities, and applications of wireless communications. The PTT online course "Wireless communications" provides the information you need.
Course objectives:
By the end of this course you will be able to:
- explain the concepts of cells, handover, location tracking, and roaming.
- explain the need for registration with authentication and authorisation of mobile devices.
- describe the various functions carried out by the core network of a mobile system.
- describe the role of the 3GPP in the evolution of mobile systems.
- describe the evolution of mobile systems from 2G to 5G with reference to the changes in the radio access and core networks and performance improvements.
- describe and compare the operation of hard and soft handover with reference to benefits of inter base station communication links.
- describe the factors that affect the size and traffic capacity of cells.
- describe how the characteristics of the air interface limit the achievable performance of a mobile service.
- describe the measures taken to minimise the use of system resources by mobile devices.
- describe and compare the methods employed by 2G through to 5G systems to maximise the capacity of cells while minimising interference.
- describe the format and role of the hierarchical numbering scheme employed by mobile systems.
