What type of information can be viewed with a Wi-Fi analyzer?

1. Only the connection speed of devices

2. The operating system of connected devices

3. Frequencies/channels and signal strength

4. Internet Protocol version used by devices

The correct answer is: Frequencies/channels and signal strength

A Wi-Fi analyzer is a powerful tool used for assessing and optimizing wireless networks. It provides a wealth of information that can help network administrators identify issues and enhance performance. One of the key pieces of information that a Wi-Fi analyzer reveals is the frequencies and channels that wireless networks are operating on, along with the signal strength of those networks. Understanding the frequencies and channels is essential for optimal wireless performance, particularly in environments where multiple networks coexist. Overlapping channels can cause interference, leading to degraded performance. By analyzing the signal strength, network administrators can determine the effective range of their wireless devices and identify areas that may require additional access points or adjustments in the configuration to improve coverage. While other information can be useful in certain contexts, such as connection speed, operating systems of connected devices, or the specific Internet Protocol versions being used, these aspects are not the primary focus of a Wi-Fi analyzer. The main strength of the tool lies in its ability to provide insights into channel utilization and signal metrics, which are crucial for maintaining a robust and efficient wireless network.
