What the free tools can't do
Every tool here stops at a number. They can't place those access points on your own floor plan, turn the layout into a predictive heatmap, or export a PDF or PowerPoint client report — that's the planner. See what each plan includes.
What is a WiFi tool?
A WiFi tool is a calculator or planner that answers one specific network-design question — how many access points a space needs, how much bandwidth an application will consume, whether a PoE switch can power every AP, or which channels avoid interference — without doing the math by hand. Rather than one heavy application, WiFi Weave breaks the planning workflow into twelve focused tools, so you reach for the single WiFi tool that matches the decision in front of you.
Every WiFi tool here runs entirely in your browser and returns results the moment you enter your details. There is no account, no email, and no usage limit — the same free-forever access across capacity sizing, coverage range, channel planning, ROI, latency impact, standards compatibility, SSID and VLAN design, and site-survey prep.
Pick a WiFi tool by the question you're answering: start with the Wi-Fi Capacity Calculator to size access points and bandwidth, then refine with the Coverage Range Estimator and Channel Planning Calculator. When a project needs predictive heatmaps on a real floor plan rather than a quick estimate, move up to our WiFi planning software.
