Comprehensive and Detailed Explanation:

A Wireless Network Management System (WNMS) is designed to monitor, configure, and manage wireless network components. It primarily interacts with theManagement Plane, which is responsible for:

Monitoring network performance.

Configuring network devices.

Managing firmware updates and policies.

This interaction allows administrators to oversee the network's health and make necessary adjustments to maintain optimal performance.

Active site surveys involve connecting to the WLAN and measuring performance metrics such as signal strength, throughput, and roaming behavior.This type of survey is essential to verify that clients can seamlessly roam between APs without connectivity issues.

The CWDP-305 Official Study and Reference Guide highlights the role of active surveys in assessing the real-world performance of a WLAN, including the effectiveness of roaming configurations.

A WLAN scanner is a lightweight tool used during deployment and validation to verify channel utilization, detect SSIDs and APs, evaluate encryption schemes (e.g., WPA2/WPA3), and assess signal strength from APs in a particular area. It is not meant to perform in-depth frame analysis but provides a high-level overview.

From CWDP-305:

“WLAN scanners are useful tools for deployment validation and troubleshooting. They reveal AP signal strength, encryption in use, and can help verify if channel plans have been implemented correctly.”

Orthogonal Frequency Division Multiple Access (OFDMA), introduced in 802.11ax, enhances efficiency by dividing a channel into smaller sub-channels called Resource Units (RUs). This allows multiple devices to transmit simultaneously within the same channel bandwidth, reducing latency and improving throughput. Unlike previous standards like 802.11n and 802.11ac, which primarily support single-user transmissions per channel, OFDMA's ability to handle multiple concurrent transmissions without relying on MU-MIMO leads to more efficient spectrum utilization and better performance in dense environments.
