Spectrum 2.4GHz is an Android application that uses your device’s Wi-Fi hardware to discover, analyze, and visualize every network broadcasting in the 2.4 GHz band. Whether you’re troubleshooting interference, selecting the least-congested channel for an access point, or auditing the security posture of networks around you, Spectrum 2.4GHz gives you the data you need across four live views.Documentation Index

What You Can Do
Network List
Browse detected SSIDs sorted by signal strength with RSSI, channel, frequency, and security details.
Channel Map
See how many networks occupy each of the 13 channels and identify saturation hot-spots.

Get Up and Running
Install the app
Download Spectrum24GHz_v1.0.0.apk from the GitHub Releases page and sideload it onto any Android 6.0+ device.
Grant permissions
On first launch, accept the location permission prompt. Android requires this to expose Wi-Fi scan results. On Android 13+ an additional Nearby Wi-Fi Devices permission is requested.
Start scanning
Tap the Escanear button. The app triggers an active scan and populates the Network List within seconds. Subsequent scans respect a 30-second cooldown — the app falls back to cached results in between.
Wi-Fi scanning on Android requires Location Services to be enabled system-wide, in addition to the app permission. If no networks appear, confirm that Location is turned on in your device settings.
