Wall-Material Attenuation Cheat Sheet
Not all walls cost the same signal. A reference for how much Wi-Fi typical building materials attenuate — drywall to glass to concrete to metal — and why.

Predictive vs. measured Wi-Fi surveys
Predictive and measured Wi-Fi surveys answer different questions. Here is what each one is for, when to spend the effort, and how a calibrated model uses both.

Why Racking Wrecks Warehouse Wi-Fi
Most predictive tools treat a warehouse like an empty box. Steel racking attenuates Wi-Fi by depth and angle — why aisles go dead, and how to model it.

A Wi-Fi heatmap without Ekahau
You do not need a subscription and a hardware kit for a predictive Wi-Fi heatmap — here is how a computed one works, and where measuring on site still counts.

The Physics of an Honest Wi-Fi Heatmap
A predictive Wi-Fi heatmap is only as honest as its physics. Here is what ITU-R P.2040, P.526, and P.1238 model, and why the more conservative answer wins.
Design Wi-Fi you can prove — before the truck rolls.
Design on real floor plans, walk it in 3D, and prove the coverage — then hand off to the field. Talk to us about what your team needs.
