Wi-Fi Pro Lab

Interactive models that show how Wi-Fi really works. Move the sliders, watch the physics change, then see what it means on real equipment. Everything on regulation starts with the UK (Ofcom) and switches to the EU or the US with one click.

How every topic worksThe same seven parts, every time

Each topic in the lab is written the same way, so you always know where to look. Read straight through, or jump to the part you need.

1. Definition: what it is, with the terms and the common mix-ups.
2. Purpose: why it exists and what problem it solves.
3. Mechanism: how it works, with a model you can play with.
4. Visual explanation: waveforms, channel maps, timelines.
5. Mathematics: the equations, with worked examples and calculators.
6. Real-world behaviour: what it looks like on actual equipment and how it fails.
7. Practical validation: Wireshark filters, spectrum views and questions to answer yourself.

The bookWhere the lab is going

The lab is being built as one book, from the physics of radio waves up to measurement and validation. Open a part to see its topics. Live topics are links; the others are planned and will appear in this order.
