types of fading in wireless communication ppt

Wireless communication is one of the most widely used forms of technology, playing a crucial role in our daily lives. With this booming industry comes a wide variety of techniques and protocols, each with their pros and cons. One of these is fading- a type of interference that can cause disruption in wireless communication. In this article, we'll cover what fading is and how it affects wireless communication.

Fading occurs when a signal becomes weaker or distorted due to interference from multiple sources. This may be caused by physical obstructions such as walls or trees, or electromagnetic interference from other wireless devices. Fading can cause disruption, reducing signal strength, slowly reducing the range of the system, or causing disruption of overall data quality.

The two main types of fading are flat and selective. Flat fading happens when the signal is weakened by the same amount across all frequencies; this type of fading is most common within short ranges. Selective fading, on the other hand, occurs when the signal is affected differently by different frequencies. This type of fading is more likely over longer distances as higher frequencies travel at a slower rate and can become easily impaired.

Both types of fading can have serious and disruptive effects on wireless communication. However, there are several measures that can be taken to minimise the impact of fading. Installations of dynamic equalization techniques and diversity antennas can help to reduce fading and improve overall performance.

In conclusion, fading is a common form of signal disruption in wireless communication that can cause issues with signal strength, range, and data quality. While fading cannot be completely prevented, there are methods available to minimise its effects and improve the performance of your wireless network. As wireless communication continues to advance, so too will the ways we tackle this issue.
