IEEE 802.11 Spectrum Planner

Visualize interference in the 2.4GHz/5GHz bands. Plan non-overlapping access point coverage for enterprise wireless deployments.

The Physics of WiFi

WiFi Channels are segments of the radio frequency spectrum allocated for data transmission. In the 2.4GHz band, channels are spaced 5MHz apart but are 20MHz wide, meaning they overlap significantly.


Non-Overlapping Rule: For a stable 2.4GHz network, only channels 1, 6, and 11 should be used. Using any other channel causes co-channel interference (CCI) or adjacent-channel interference (ACI), which leads to packet loss and high latency.

5GHz Band: This band offers much more bandwidth and many more non-overlapping channels (e.g. 36, 40, 44, 48), making it superior for dense enterprise environments.

Frequently Asked Questions

Can I use these networking tools without installing any software?

Yes. All IT and networking tools run directly in your browser. There is nothing to install, no configuration required, and they work on any operating system.

How accurate is the network diagnostic information?

The tools query live DNS resolvers and use your browser's network APIs for real-time data. Results reflect your actual network conditions at the time of the query.

Can IT professionals use these tools for client network diagnostics?

Yes. These tools are designed for professional use and provide accurate, real-time network information suitable for diagnosing DNS misconfigurations, IP conflicts, and connectivity issues.
