AirMagnet Planner
AirMagnet Planner makes it easy to build a detailed model of any WiFi environment. Simply load in a map of your location, and use the built-in library of walls, doors and windows or specify your own custom materials to precisely match the building's characteristics. Your map now becomes a platform to simulate performance based on the correct number, placement and configuration of APs. Tweak any number of these settings until you achieve full coverage for end-users while minimizing signal bleed into unsecured areas. Generate a full report of your wireless environment, including a bill of materials for your infrastructure purchase.
