Which tool verifies RF spectrum for valid Wi-Fi networks and sources of non-Wi-Fi interference?

Chanalyzer is a specialized RF spectrum analysis tool developed for use with Wi-Spy spectrum analyzers. It is used to visualize and validate Wi-Fi and non-Wi-Fi interference sources across the 2.4 GHz and 5 GHz bands.

According to the RUCKUS One Online Help – Spectrum Analysis and RF Interference Tools , spectrum analysis tools like Chanalyzer can detect non-802.11 interference sources such as microwave ovens, Bluetooth devices, DECT phones, and radar signals. While RUCKUS APs have built-in spectrum analysis mode , Chanalyzer provides external, high-resolution spectrum visualization that helps confirm interference sources in physical environments.

In contrast, RUCKUS Wi-Fi Planner (or Wi-R Planner ) is used for predictive RF design and coverage estimation, not live interference detection. The WLAN discovery tool identifies SSIDs and basic network parameters but cannot detect non-Wi-Fi signals.

Therefore, the correct answer is D (Chanalyzer) — the standard tool for verifying valid Wi-Fi operation and identifying non-Wi-Fi interference sources.
