Planning tool
Wi-Fi heat map planner
Upload a floor plan (PDF or image), set its scale, trace the walls by material and place access points. The heat map shows the signal a phone or laptop would receive at every point.
Method
How the heat map is predicted
The multi-wall model
The planner uses the multi-wall propagation model that predictive survey tools are built on. Signal falls with distance from each access point, measured in 3D from the ceiling to a device at desk height. Every wall the signal passes through then takes its own loss.
Walls by material and band
Each material has its own loss at 2.4, 5 and 6 GHz, from a few dB for drywall or clear glass to 25 dB or more for reinforced concrete and metal. Higher bands lose more. A wall crossed at an angle costs more than one crossed straight through, because the signal passes through more of it.
Furniture and people
Open floors, furnished offices and racked warehouses absorb signal differently between the walls. The "space between walls" setting covers that.
Design targets
- −67 dBm: voice, video, roaming
- −70 dBm: reliable data
- −75 dBm: basic browsing
The second-strongest view shows where a device can hear two access points at the target, which seamless roaming for calls and video needs.
What a site survey still checks
Real walls vary with thickness, moisture, wiring and hidden metal. Interference from neighbouring networks, channel planning and the devices people actually use matter too. Treat the heat map as a predictive design to validate on site, not a guarantee.
