AP Placement & Coverage

AP placement is the process of determining the optimal physical location for access points to ensure complete wireless coverage across a space without dead zones or excessive overlap. Signal strength degrades with distance and is affected by physical obstacles like walls, floors, glass, and metal, so engineers must account for building materials and layout when planning deployments. Good AP placement balances coverage, capacity, and interference. Placing APs too far apart creates dead zones, while placing them too close causes co-channel interference that degrades performance for all connected devices.
