Assumptions
Results update as you type. Example figures are illustrative.
Your working data
Edit cells directly or import a CSV. Download “Input CSV” for the required column names. Up to 200 rows; scroll the table sideways for additional fields.
Detailed analysis
Exports include all results, regardless of the search filter. The HTML report includes assumptions and source data; use your browser’s Print command for PDF.
Chart shows the first 20 rows; negative values use a warm color. Click table headers to sort.
Compare up to four scenarios
Capture the current inputs, change assumptions and capture again. Scenarios are included in downloaded projects.
What this model includes
No wireless scanning. Illustrative rectangular spectral-overlap model for 20/22 MHz networks only; not a throughput or interference measurement. Confirm allowed channels on your router.
Import and save safely
CSV imports use your current assumptions. Project files restore assumptions, rows and saved scenarios. No automatic saving: download a project before closing this page. Imports are limited to 10 MiB and 200 rows. Calculations run in your browser; the site’s advertising and analytics follow its privacy policy.

Using Wi-Fi Channel Overlap Analyzer
Enter nearby 2.4 GHz networks manually and compare channel overlap with signal-weighted scores for channels 1, 6 and 11.
- Set the channel width you assume.
- Enter each nearby network from your Wi-Fi app with its channel and signal.
- Read the suggested channel beside your table and confirm it is allowed on your router.
Example
The worked example includes Neighbor A, Neighbor B, Neighbor C, Neighbor D. Change the first assumed channel width (mhz) setting and compare the result with a saved baseline.
Questions & answers
What does Wi-Fi Channel Overlap Analyzer calculate?
Enter nearby 2.4 GHz networks manually and compare channel overlap with signal-weighted scores for channels 1, 6 and 11.
What are the important limitations?
No wireless scanning. Illustrative rectangular spectral-overlap model for 20/22 MHz networks only; not a throughput or interference measurement. Confirm allowed channels on your router.
Can I continue my work later?
Yes. Save a project JSON file and reopen it with Import CSV / project. It contains the working data, assumptions and up to four scenarios. Nothing is saved automatically.
What CSV columns do I need?
network, channel, rssi. Download Input CSV for a compatible example. CSV imports keep your current assumptions.
Are these example figures current industry benchmarks?
No. They are illustrative values to demonstrate the model. Replace them with figures appropriate to your situation.
