Best WiFi Heatmap Tools

What Is a WiFi Heatmap?

---

A WiFi heatmap is a map of wireless signal coverage and strength. Typically, a WiFi heatmap shows a real map of a room, floor, or even a city overlaid by a graphical representation of a wireless signal.

Professional network administrators and regular home users alike use WiFi heatmaps to find dead zones and make adjustments to achieve the desired coverage. Without a heatmap, wireless network optimization involves a lot of guesswork, which is why most people who are not aware of the existence of WiFi heatmap software never manage to achieve the WiFi coverage they would like to have.

WiFi heatmap software fully automates the process of mapping WiFi coverage on a map, allowing anyone to create a WiFi heatmap in a matter of minutes just by walking from one place to the next until the entire area is mapped.

The heatmap will tell you exactly where your wireless signal is the strongest and where it could be improved.

Besides its wireless heatmap capabilities, NetSpot is also a great WiFi analyzer. Switch to the Discover Mode and let NetSpot collect detailed information about nearby wireless networks, including those that do not broadcast their SSID, showing you what kind of security settings the networks use, which channel they broadcast on, and how strong their signal is, among other things.

Despite having so many useful features, NetSpot never lets its users wonder which button they should click on to accomplish what they want to do. Because of its ease of use, professional features, attractive price, and stellar customer support, NetSpot has established itself as a leading heatmapper and WiFi analyzer, earning the top spot on this list.

5. AirMagnet Survey PRO

AirMagnet Survey PRO can automatically create easy-to-read heatmaps for signal/noise, WLAN throughput, PHY data rates, retry rates, and packet losses. This heatmapper supports all WiFi network standards and surprises with its large number of supported features. Unfortunately, AirMagnet Survey PRO has a slightly outdated user interface, which can be unintuitive at times.

If you frequently need to create WiFi heatmaps, you will most likely get over the clunky user interface relatively soon. But if you’ve never created a WiFi heatmap before and don’t know if you will ever need to create one again, a more user-friendly WiFi heatmapper, such as NetSpot, is a better choice for you.
