A practical starting point

The small checks that keep a design moving.

Use the toolbox for quick engineering work: test an assumption, compare a setting, or look up a connector detail before the next conversation or site visit.

Clear inputs and useful results, without a setup process.

Built for wireless engineers, installers and anyone planning the physical network.

Open a tool directly, save the link, and come back whenever you need it.

Wi-Fi toolbox questions

Are these Wi-Fi engineering tools free?

Yes. All five standalone tools are free to use in your browser without an account or subscription. Wi-Fi Studio provides a separate project workflow for design, survey and reporting.

Can I use the results as a completed Wi-Fi design?

The calculators provide engineering references based on your inputs. MCS values are PHY rates, not speed-test results. Validate RF and power assumptions against equipment specifications, site conditions and measured performance.

Does a connector match guarantee antenna compatibility?

The guide compares connector style and count. Confirm the exact AP and antenna, supported frequencies, radio-to-port mapping and manufacturer requirements. Radiation-pattern references are available for some models; the library does not cover every antenna.

When the work becomes a project

Take the engineering into Wi‑Fi Studio.

Studio brings your project work together when you need a connected place to inspect, design, survey and report.

  • Keep engineering decisions with the wider project
  • Move from early calculations into your design work
  • Work across inspection, design, survey and reporting
