Description: Radio frequency (RF) system design forms the basis of wireless communications. The RF course provides an overview of the principles of RF system design, including the use of antennas, propagation models, and interference mitigation. It describes a classification of RF systems and then covers the basic functions of antennas, including the near and far fields, antenna gain, directivity, and radiation characteristics. Important RF propagation mechanisms are reviewed, such as the curvature of the RF beam and maximum RF range, surface (ground) wave, space wave, sky wave (ionospheric propagation), scatter propagation, and earth-space propagation. RF propagation impairments are described, including how multipath fading, interference, and noise will impact the threshold received power. Transmitter issues,  crosslink Interference, and remote interference and management are also covered. The models governing free-space propagation, outdoor propagation models, and smoothness criteria are studied, together with link budget and receiving antenna electric field calculations. The RF course comprises 80 informative slides that are meticulously crafted to maximize clarity and accelerate learning.Key Learning OutcomesSpecify and design a radio frequency systemStudy the basic functions of antennas and various antenna systemsIdentify different RF propagation mechanisms and transmission modesUnderstand the RF communications impairmentsThe Project 25 (P25) is a global standard for two-way non-public radio networks that have been adopted by many industries such as utilities, airports, transit, petroleum, and chemical companies that rely on mission-critical communications and interoperability with public safety agencies in an emergency. The operating distance of such networks can be up to 32 miles, far exceeding 4G and 5G mobile cellular networks. The second part of this course discusses the P25 goals and system model and its
