Why this RF course?
Wireless communication is an important part of our lives today. A knowledge of the fundamentals of Radio Frequency (RF) communication will enable you to:
- Understand the essentials of any wireless technology, network or system.
- Appreciate the capabilities of wireless technologies: what they may be able to deliver and their limitations.
- Understand the language and terminology of wireless systems.
- Understand wireless product descriptions and specifications.
- Appreciate many of the limitations of wireless systems, and why those limitations exist.
This course serves as a primer for further training or study in Wireless systems and RF communications.
RF Training Course Objectives
On completing this course, you will be able to:
- Understand the issues surrounding radio spectrum and why it is such a scarce resource.
- Be aware of radio channels, their use and the impact of Shannon’s Law.
- Appreciate the need and use of the deciBel and related dB quantities.
- Understand some of the impacts on radio signal propagation.
- Appreciation the role of modulation and the different modulation schemes.
- Understand the role of Forward Error Correction and coding schemes.
- Continue your education in Wireless systems, networks and technologies.
Who should attend this RF course
- Anyone who needs to understand the basics of Radio Frequency communications and wireless systems.
- People who are new to RF communications, but who want to attend more advanced wireless courses.
RF Course Pre-requisites
The course assumes a basic awareness of mobile communications such as can be obtained by attending the LEVER course A Primer in Mobile Communications. No previous radio knowledge is assumed.
Lifetime Post-Course Support
After completing this RF training course, delegates receive lifetime post-training support from LEVER Technology Group, to help them apply the technologies and skills they have learned with us, to provide career-long support, and to ensure they are better equipped for their future roles in IT and networking.
