Estimate WiFi signal strength, speed drop, dead zones and best router placement for home rooms.
The simulator combines your inputs into a practical score, primary estimate, warning level and 2-3 action tips. Green means the scenario is broadly comfortable, amber means watch the assumptions, and red means there is a meaningful risk to review before acting.
This is an estimate, not a guarantee. The formulas use practical India-focused defaults, common safe limits, and simple penalty factors for load, heat, speed, EMI pressure, signal loss or affordability strain depending on the tool.
Compare this simulator with nearby calculators and planning tools.
A central, raised, open location usually works best. Avoid cabinets, corners and thick walls near the router.
2.4 GHz travels farther through walls. 5 GHz is faster nearby but loses strength faster with distance and walls.
Each wall reduces signal. Concrete, brick, metal and mirrors usually cause bigger drops than wood or drywall.
Yes. More active devices share airtime and can reduce usable speed, especially on basic routers.
A dead zone is an area where signal strength or usable speed is too low for reliable browsing, video calls or streaming.
