Comprehensive and Detailed Explanation:

The 5 GHz band offers more non-overlapping channels and is less susceptible to interference compared to the 2.4 GHz band. By moving corporate data clients and VoWiFi devices to the 5 GHz band, the network can achieve better performance and reduced interference, especially for latency-sensitive applications like voice over Wi-Fi.

Interference primarily affects the receiver's ability to demodulate signals. In a point-to-point link, RF interference occurring at the middle of the link has little to no impact unless it reaches either endpoint. Therefore, the focus must be on minimizing interference at the receivers.

From CWDP-305:

“Interference at the receiver is the key concern in bridge links. The energy must be received cleanly to enable demodulation, so interference near the receiving AP is more critical than in the link’s midspan.”

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.
