WiFi channel planning for 2.4, 5 and 6 GHz
Which channels and widths to use in each band, why 1, 6 and 11 still matter, what DFS means and how to keep neighboring access points from interfering.
PropagationHow much WiFi signal does each wall material absorb?
Typical attenuation of drywall, glass, brick, concrete and metal at 2.4, 5 and 6 GHz, what makes real walls different, and how to measure your own.
Site surveyHow to do a WiFi site survey, step by step
Passive and active surveys, what equipment you need, how to walk the site, and how to use the results to validate and calibrate a predictive design.
PlacementCeiling or wall: where to mount an access point
How ceiling and wall mounting change the coverage of an access point, the mistakes that cost the most signal, and when a directional antenna makes sense.
