Multi-floor planning - You can now add unlimited floors, each with its own floorplan and walls. Signal from APs on other floors bleeds through realistically based on the slab material (wood frame, concrete, reinforced concrete, steel deck). The channel solver sees across floors too, so it won't put two APs on the same channel if they're directly above each other through a wood floor.
Free, open-source WiFi planner that runs in your browser. Drop a floorplan, place access points from 100+ real models, and see signal coverage through walls in real time. Each wall material has realistic RF attenuation. Glass, brick, concrete all behave differently. Channels are assigned automatically, and a 3-stage optimizer finds ideal AP placement.
