WiFi planning software that works on your real floor plan
Import the building, model the walls, place access points, and see predicted coverage across 2.4, 5 and 6 GHz before anyone runs a cable. Runs in the browser — nothing to install.
Free plan includes floor-plan upload, wall drawing, AP placement and 3 AI planning runs.
How a plan gets built
Five steps, in the order you actually do them.
Import your floor plan
Upload a PDF, image or CAD export of the real building and set the scale. Ekahau .esx projects import directly, and access points can come in from UniFi, Meraki or Aruba controllers.
Model the walls
Draw walls by material — drywall, concrete, glass, metal — because attenuation is what actually decides coverage. On Pro, AI detects walls from the floor plan image for you.
Place access points
Place APs by hand from the device library, or let the auto-planner propose positions and channels for the coverage and capacity you specify.
Read the heatmap
Predictive coverage across 2.4, 5 and 6 GHz — signal strength, data rate, SNR, interference and capacity views, so dead zones surface on the plan instead of on site.
Export the evidence
PDF and PowerPoint reports, channel plans, CSV and a bill of materials — the documents a client or a change board actually asks for.
What you get free, and what you pay for
A lot of “free WiFi planners” are trials in disguise. Here is the actual line.

Built for the buildings you actually plan
Offices
Desk density, meeting-room capacity and the glass partitions that quietly kill 5 GHz.
Warehouses
High ceilings, racking that changes as stock moves, and scanner coverage down every aisle.
Schools
Classroom-scale device density at bell times, plus hall and outdoor coverage.
Healthcare
Lead-lined and solid walls, roaming for clinical devices, and no-dead-zone requirements.
Hotels
Per-room coverage through repeated wall stacks without over-deploying radios.
Retail
Stockroom-to-shopfloor coverage, POS reliability and guest WiFi separation.
Start with a calculator, no account required
Sizing a job before you commit? The capacity calculator estimates access point count, the PoE calculator checks your switch budget, and channel planning sorts out interference.

What is WiFi planning software?
WiFi planning software models how wireless signal will actually propagate through a specific building before anything is installed. You supply a floor plan and wall materials, position access points, and the software predicts coverage, data rates and interference — so you can fix dead zones and right-size the AP count on the plan rather than discovering problems after the cabling is done.
Is there a free WiFi planner?
Yes. WiFi Weave has a free plan with no credit card required: upload your own floor plan, draw walls, place access points from the full device library, see basic coverage, and use 3 AI planning runs. There are also 12 free calculators — capacity, PoE budget, channel planning, bandwidth and more — that need no account at all.
Do I need a site survey as well?
Predictive planning and site surveys answer different questions. Planning tells you where to put access points and what to buy; a survey validates what was actually built. WiFi Weave covers the predictive side and can import survey measurements so you can compare predicted against measured coverage on the same floor plan.
How many access points do I need?
It depends on area, wall materials, device density and the applications in use — a warehouse and a classroom of the same square footage need very different designs. Our free WiFi capacity calculator gives a first estimate in about a minute, and the planner refines it against your actual floor plan.
Does it run in the browser?
Yes — there is nothing to install and no Windows-only client. You sign in and work in the browser, which also means a colleague or client can be shown a plan without installing software.
What does WiFi Weave cost?
The free plan is $0 with no card. Basic is $29.99/month, Pro is $49.99/month with AI wall detection, the auto access point planner and every visualization mode, and MSP is $99.99/month adding client sharing, comments, version history and advanced reporting. All paid plans are monthly and cancel anytime.
