COURSE OVERVIEW
RFI is experienced in all radio communication systems, on the ground, in the air and on the sea, and in space. Radio Frequency Interference (RFI) in Wireless Communications Training course will address all principal uses of radio and wireless and how RFI can be assessed and resolved. The approach is based on solid technical methodologies that have been applied over the years yet consider systems in use today and on the near-term horizon. The objective is to allow the widest variety of radiocommunication applications to operate and co-exist, providing effective methods of identifying and resolving RFI before, during, and after it appears.

COURSE OBJECTIVES
Upon completing this Radio Frequency Interference (RFI) in Wireless Communications Training course, learners will be able to meet these objectives:
- The objective of this three-day Radio Frequency Interference (RFI) in Wireless Communications Training course is to increase knowledge in the area of RFI and EMI compatibility as well as the risk of potential interference among various wireless systems. The interference cases would result from the operation of one system as against others (e.g., radar affecting land mobile radio, and vice versa; satellite communications affecting terrestrial microwave, and vice versa).
- It is assumed that all operating equipment has been designed and tested to satisfy common technical requirements, such as FCC consumer certification and MIL-STD 461F. As a consequence, RFI is experienced primarily through the antennas used in communications. The overall context is spectrum and frequency management to enhance knowledge in identifying and mitigating potential interference threats among various systems. Attendees are expected to have a technical background with prior exposure to wireless systems and equipment.
CUSTOMIZE IT
- We can adapt this Radio Frequency Interference (RFI) in the Wireless Communications course to your group’s background and work requirements at little to no added cost.
- If you are familiar with some aspects of this Radio Frequency Interference (RFI) in Wireless Communications course, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the Radio Frequency Interference (RFI) in Wireless Communications course around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Radio Frequency Interference (RFI) in the Wireless Communications course in manner understandable to lay audiences.

COURSE SYLLABUS
Key concepts of evaluating radio frequency interference:
- Elements of a wireless or radio communication system – land-based point-to-point and wireless/cellular, space-based systems
- Types of electromagnetic interference – natural and man-made (unintentional and intentional)
- Interference sources – conducted and radiated, radar signals, RF intermodulation (IM)
- Levels of RFI – permissible, accepted, harmful
Signals, Bandwidth and Threshold Conditions
- Modulation – analog and digital
- Source encoding and error-correcting codes
- Adaptation to link conditions
- Spread spectrum
- Eb/N0, protection ratio (C/I)
- Computing minimum acceptable signal (dBm at receiver input)
Spectrum Allocations and Potential for Sharing with Acceptable Interference
- Current frequency allocations for government and non-government use (1 MHz through 100 GHz)
- ITU designated bands for sharing as Primary and Secondary services
- Sharing criteria – as mandated, as negotiated
Link Budget equations
- Line-of-sight propagation, range equation, power flux density
- Evaluating antenna properties and coupling factors
- Calculating C/I from antenna characteristics – homogeneous and heterogeneous cases
RFI on Obstructed Paths
- Path profiles and obstructions
- Diffraction and smooth earth losses
- Path analysis tools – HD Path
Atmospheric losses and fading
- Constituents of the atmosphere
- Tropospheric losses
- Near-line-of-sight paths; Ricean fading model
- Obstructed paths (in building and concrete canyons); Rayleigh fading
Interference analysis examples between various systems
- Service performance in the presence of interference, interference control through design and coordination
- Radars vs. land mobile and LTE systems
- WiFi and Bluetooth
- Satellite communications vs. terrestrial microwave systems
Frequency reuse and signal propagation
- Cross polarization on the same path
- Angle separation through antenna beam selection
- Cellular pattern layout – seven and four color reuse patterns
- Non-steady state propagation – scatter, rain-induced interference, ionospheric conditions
How to identify, prevent, and fix common RFI problems
- Identifying interference in the real world – detection, location, resolution
- Physical separation, orbit separation
- The site and terrain shielding
- Interference suppression – filtering, analog, and digital processing techniques
