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.

The toolbox

Five tools for everyday Wi‑Fi engineering.

Each tool opens in the standalone toolbox. Use the direct links below to start exactly where you need to.

01 · RF

Power & link budget

Work through transmit power, antenna gain, cable loss and estimated receive level.

02 · AIRTIME

SSID beacon overhead

Estimate beacon airtime as SSID counts, radio counts and basic rates change.

03 · RADIO

MCS PHY rates

Look up theoretical PHY rates by Wi‑Fi mode, channel width, spatial streams and MCS.

04 · POWER

PoE budget

Estimate device demand against a switch budget and keep suitable installation headroom.

05 · ANTENNAS

Connector reference

Shortlist antennas by connector type and count, then confirm the physical connection match.

Using the tools

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
