WiFi Signal Analyzer

The WiFi Signal Analyzer processes input measurements (RSSI, noise floor, channel, band) to compute key wireless-health metrics and provide actionable optimization guidance. It supports 2.4 GHz and 5 GHz scans and can aggregate data across multiple APs for a holistic view.

Core calculations include Signal-to-Noise Ratio (SNR = RSSI − Noise) and a Channel Occupancy metric derived from observed frames. An InterferenceIndex estimates pressure on each channel from co-channel and adjacent-channel activity. Based on occupancy and interference, the tool suggests a preferred channel and width (e.g., 20/40/80 MHz) and outputs a health_score (0–100) along with a concise summary for operators.

This tool benefits network admins, IT technicians, and advanced home users conducting site surveys, post-deployment validation, or trouble-shooting. Its value lies in providing consistent, rule-based recommendations aligned with IEEE 802.11 standards, reducing guesswork when selecting channels or adjusting widths. It supports exports (CSV/JSON) for integration with existing workflows and can compare current results to historical scans to track improvement over time. The unique value is its explicit, regulator-aware guidance across both 2.4 GHz and 5 GHz bands, including DFS considerations where applicable.
Use cases include diagnosing coverage gaps, selecting least-congested channels, validating post-migration performance, and preparing channel plans for new AP deployments.
