2. What is Fading ??? Fading: rapid fluctuations of received
signal strength over short time intervals and/or travel distances.
The fading phenomena results as a result of constructive
interference or Destructive interference at the receiver side.
Caused by interference from multiple copies of Tx signal arriving @
Rx at slightly different times
3. How Fading Occur ???? Fading signals occur due to
reflections from ground & surrounding buildings (clutter) as
well as scattered signals from trees, people, towers, in a Large
4. Types Of Fading : There two Main Types of Fading 1) Small
Scale fading 2) Large Scale Fading The Topic which I will Discuss
here is the large Scale Fading. Large Scale Fading is also Called
5. Large Scale Fading: Large Scale Fading occurs when an
obstacle gets positioned between the wireless device and the signal
transmitter. This interference causes significant reduction in
signal strength because the wave is shadowed or blocked by the
6. Detail In the Diagram It is Clearly Given That there is an
obstacle between the Transmitter(Base station) and the
receiver(Mobile Station) Due to which a great variation occur in
the strength of the received signal. 2)The measured signal power
differ substantially at different locations even though at the same
radial distance from a transmitter. 3)Represents the medium scale
fluctuations of the radio signal strength over distances from tens
to hundreds of meters
7. Detail Every Electromagnetic signal has its means average
power now when the phenomena of large scale fading occur then this
value deviates from the mean average value.
8. Large Scale Fading is Different from small Scale Fading:
Small scale fading is concern with rapid fluctuation of received
signal strength over very short distance and short time where as,
Large scale fading concern with large fluctuation.
