Length: 20 pages

This introductory course is intended for RF engineers and non-RF engineers involved in the design, deployment and testing of wireless communication systems. Wireless systems exist today in the form of cellular phone service, emergency services radio networks, remote metering and control systems, automatic vehicle location, distributed antenna systems (DAS), Wi-Fi, WiMAX, and Microwave, to mention a few.

This course provides an introduction to the phenomena of radio frequency (RF) interference and its impact on system performance. Consideration for RFI is a very important subject when designing a wireless system, as it will have a direct impact on system performance, user confidence, and ultimately the user’s experience. Lack of care when evaluating RFI has the potential of becoming very costly if addressed after a system has been deployed.

The course begins with a high-level description of the elements of a communication’s link, then it will describe the most common types of RF interference, and how they are generated. This course will also review the effects of interference on system performance through illustrative examples. And finally, the course will address various methods to minimize the possibility of RFI and maintain system performance.

Learning Objectives

Upon completion of this course, participants will be able to:

• Distinguish the elements of a radio frequency communications link with sufficient accuracy to distinguish them from related concepts.
• Summarize the description of radio frequency interference (RFI) and demonstrate understanding through an assessment question or scenario.
• Determine sources of RFI with sufficient accuracy to distinguish them from related concepts.
• Estimate RFI using course principles and given data.
• Diagnose the impact of RFI on system performance and determine the resulting implications for system performance or safety.
• Evaluate RFI mitigation techniques in a representative engineering or safety scenario.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 10 questions. CPD credits are not awarded until the course is completed and quiz is passed.
