WHAT'S IN THE TOOLBOX
Quick checks for Wi-Fi planning work
Use these calculators as planning references, then validate a design against the equipment datasheet, site conditions and measured results.
SSID beacon overhead
Estimate beacon transmit airtime as SSID count, beacon size, rate and interval change on a shared channel.
MCS lookup
Look up nominal PHY rates by Wi-Fi generation, channel width, spatial streams, MCS and guard interval.
PoE budgeting
Compare access point and device power requirements with available switch budget, port capability and reserve.
Antenna connector guide
Compare listed AP and antenna connector styles and connection counts. Check the exact model and manufacturer guidance before installation.
Radiation pattern reference
Browse imported antenna-pattern references by manufacturer and model. Pattern metadata and mounting orientation require independent verification.
FAQ
Using the Wi-Fi engineer toolbox
Are these Wi-Fi calculators free to use?
Yes. The tools run in your browser and do not require an account or subscription.
Do the tools replace a wireless survey or equipment datasheet?
No. They provide planning checks. Confirm assumptions with current vendor documentation, site conditions and survey measurements.
Where are my calculator inputs stored?
Inputs are remembered only on the device and browser you use.
