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

This online course describes the radio communications between a mobile user's equipment and the fixed infrastructure provided by the mobile operator, that is, between a mobile and a base station. Topics discussed include methods of sharing radio spectrum, causes and effects of interference and fading and methods of ensuring secure communications.

It is suggested this course is studied as preparation for the other courses covering specific generations of mobile system such as GSM, UMTS and LTE.

Before studying this course you should have a clear understanding of the structure of mobile networks, including the components of the core network. You should also be familiar with the terms authentication and authorisation. The course MBA: Introduction to mobile systems covers these topics.

This e-learning course has a comprehensive range of interactive training facilities to provide a total learning experience. Technical words and acronyms have links to an online glossary giving an instant explanation. Interactive simulations explain concepts and systems operation. Onscreen question sessions at the end of each module test understanding and provide further guidance and instruction. Revision links provide quick access to subjects previously discussed and relevant to the module being studied. Once studied as a structured, assessed course, the content can be browsed for revision or reference.

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.
- explain the concepts of handover and roaming.
- explain the characteristics of data traffic and their impact on mobile networks.
- describe methods of providing access to and from a basestation by many mobiles.
- describe frequency bands in use, frequency allocation methods and considerations affecting how frequency bands are used.
- describe the need for, and methods of implementing, secure communications over the air interface.
