Webinar: Radio Propagation Mechanisms Explained (Recorded)

Recorded: 23rd March 2023

Webinar recording of Radio Propagation Mechanisms Explained is now available on Wray Castle Connect (Free Membership Required), you can view the recording here.

The aim of this Webinar is to explain the range of factors that impact the way radio waves propagate and therefore impact radio connectivity and coverage in fixed and mobile radio systems.

The session commences with a look at how variations in atmospheric conditions will affect the trajectory of radio signals – the process of refraction. The natural phenomena of diffraction, reflection, and absorption will then be described, finishing with an explanation of fast and slow fading. An understanding of these mechanisms should allow an appreciation of why sometimes a useable signal cannot be found where it would appear to be a certainty, and why a useable signal can be found where it would be thought to be impossible.

The session ends with an examination of the challenges and opportunities that millimetre wave spectrum offers for 5G system coverage and capabilities.

Topics to be discussed include:

Space Wave Propagation
Relationship between Distance and Frequency
Effects of Tropospheric Refraction
Impact of Temperature, Humidity, and Air Pressure
Radio Refractive Index Gradient
Super and Sub-refractive Conditions
Free Space Loss
Environmental Effects
Knife Edge Diffraction

Multiple Obstructions
Multipath Propagation
Slow Fading
Fast Fading
Example Realistic Cell
New Radio Spectrum for 5G
Millimetre Wave Propagation
Atmospheric Absorption
Penetration Losses
Foliage Losses
