NetSurveyor: WiFi Analyzer

NetSurveyor is a Wi-Fi network analyzer for Android. It scans the surrounding RF environment and reports what's actually on the air — every access point in range, the channels they occupy, their signal strength, and how they're configured — so you can diagnose coverage, interference, and configuration problems without setting up a laptop. It's built for the people who work with wireless infrastructure: network engineers, IT administrators, integrators, and field technicians. Scan data is presented clearly enough to act on — identify which channels are congested, confirm a newly deployed access point came up the way you intended, watch signal strength as you walk a site, and find the misconfigured or unexpected radio that's degrading a network. Capabilities: • Discovers nearby access points with SSID, BSSID, channel, band, and security type • Reports signal strength (RSSI, in dBm) for each network, refreshed continuously • Visualizes channel usage across the 2.4 GHz and 5 GHz bands to reveal congestion and overlap • Graphs signal over time, so you can survey coverage as you move through a space • Surfaces each network's security configuration at a glance NetSurveyor reports the wireless environment as it is — no accounts, no cloud dependency, just the scan in front of you.
