CompTIA Security+ Certification SY0-601: The Total Course - Wi-Fi Coverage and Performance

The video tutorial covers Wi-Fi signal strength, its measurement in decibel milliwatts (DBM), and the importance of conducting Wi-Fi site surveys to ensure optimal network performance. It discusses how atmospheric conditions like rain or sandstorms can affect Wi-Fi signals. The tutorial also explains how to build a cantenna to extend Wi-Fi range and the significance of avoiding channel overlapping to prevent interference. Finally, it demonstrates using the Netspot tool for analyzing Wi-Fi networks and creating heat maps to visualize signal strength.

What are the potential issues caused by overlapping Wi-Fi channels?

Describe how a heat map can be used in a Wi-Fi site survey.

What security standards should be considered when assessing Wi-Fi networks?
