This course is for anyone involved in Wireless communications from those just starting out, those specifying and designing, through to actual installation engineers. It has been designed to ensure that the student understands the components involved in creating a successful radio link. Looks at how radio transmission works, the technical considerations involved and also comparing microwave and or fiber optic transmission to supply the emerging and ever increasing information/communication demands.

Pre-requisite experience

No pre-requisite experience is required to take this course as the subjects covered will be of interest to anyone working in the RF and Wireless fields in any aspect.


  • To provide the student with fundamental information to help them understand the basics of wireless systems and infrastructure.
  • Understand the terms used in wireless including unit of measurement
  • Discuss wireless design and the components involved from one end to the other
  • Look at cellular transmission, with past, current and future technologies from 1G to 5G and WiFi

How will I learn?

You will study this course online in a self-paced format. The course is made up of a number of webcast lessons and online multiple choice assessments giving immediate feedback. The course content is supplemented by some PDF and video support material. It is highly recommended that the student augment their learning with real world design and installation experience, preferably with the help of experienced colleagues or mentors.

Successful completion will require:

Any level of pass in the accumulative overall assessment score.

Is this the right course for me?

If you have an interest in RF Wireless communication networks, specification, termination, cabling, antennas and need to understand the principals, then this course is for you. Even if you are unlikely to ever physically do any practical work in your current job role, understanding what is involved is also very important to help in a project.
