This course is for anyone involved in wireless communications inside buildings, from those just starting out to those specifying and designing, through to 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 compares DAS and small cell systems in supplying the emerging and ever increasing information/communication demands.
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 associated infrastructure inside buildings.
- Understand the terms used in wireless including units of measurement
- Discuss in building wireless design and the components involved from end to end
- Look at cellular networks, with past, current and future technologies from 1G to 5G and Wi-Fi
- Investigate different cabling options and look at antenna theory, design and placement

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 and 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 experienced colleagues or mentors.
Any level of pass in the accumulative overall assessment score.
If you have an interest in indoor 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 RF design work in your current job role, understanding what is involved is also very important to help in a project.
You will receive a course certificate that may be self-printed.
