Wifi Heat Map Software & Tools for Site Surveying and Troubleshooting Wireless Networks

Wifi Heat Map Software and Tools

Marc Wilson UPDATED: January 16, 2024

Buying a powerful Wifi receiver/transmitter will not necessarily improve your weak signals and dead zones. Getting a pair of Wifi bridges will not always improve performance; on the contrary, they can create signal leakage, which comprises security. Without proper planning and mapping, your wireless network design has a high chance of failing.

Mapping is the key.

In a Wireless Local Area Network “WLAN,” the radio wave signals are difficult to grasp and visualize. Wireless signals can be affected by physical objects, radio/electrical interference, and even the environment. A single mirror and a concrete wall can decrease the signal over 75%.

How can you know where your coverage area is? Where are your dead zones? How can you tell whether your signal is leaking?

Here is our list of the best Wifi Heat Map Software:

  1. SolarWinds Wifi Heat Map – EDITOR'S CHOICE This attractive tool overlays the signal strength of your Wifi APs on an floorplan of your premises. It also shows the locations of all of the endpoints in the office – click on one to see its address details. Runs on Windows Server.
  2. Acrylic Wi-Fi Heatmaps This WiFi analysis system creates a heatmap over the layout of your premises and performs signal strength investigations with recommendations of how you can improve your Wifi service. Runs on Windows.
  3. NetSpot This Wifi heatmap creator is available in free and paid versions and it will portray wireless signal strength over a layout of your location. Runs on Windows and macOS.
  4. VisiWave Site Survey This wireless signal mapping service will help you see unauthorized devices and Wifi leakage as well as a floorplan of your premises with the signal footprint shown on it. Runs on Windows.
  5. AirMagnet Survey PRO This is a comprehensive wireless network monitoring service that keeps track of traffic statistics while also showing a visual representation of the office network signal footprint. Available for Windows and macOS.

What is a Wi-Fi heatmap?

A Wifi Heatmap is a two-dimensional graphic representation of the signal strength in a Wifi network. It shows the coverage of wireless signals in different colors portrayed in a real map of an office layout, floor, or even a metropolitan area.

A heatmap also gives a quick summary of information about the wireless network and its connected clients.

Having a visual map gives the network admin amazing insights on how to adjust the wireless Access Points “APs” to improve signal coverage and avoid dead zones. Heatmaps can also help wireless engineers when doing a site survey and planning for capacity.

The Best WiFi Heatmap Software & Tools

Wifi Heatmap software automates the coverage mapping process. You need to upload an office plan or blueprint, walk around with the connected client to let the software collect data, and the software will automatically create the map.

Finding the right software can be challenging. That is why we came up with the six best Wifi heatmap tools to help in your decision.

Wifi Heat Map Software FAQs

How do I create a heat map for Wi-Fi?

Typically, a heatmap includes a color-coded representation of the signal footprints on a site. This isn’t possible to do manually without extensive software development and there isn’t much point in creating your own Wifi heatmap tool when there are plenty already available off the shelf. So, the best way to create a Wifi heatmap is to buy a commercial heatmap tool and upload your location’s floorplan into it.

What is Wi-Fi heat mapping?

A Wifi heat map shows the signal coverage of wireless access points (APs). The display is color coded to easily recognize the signal strength of an AP in any location. Underlying the heat map should be a floor plan of the location.

How do you analyze a wireless network?

In order to analyze a wireless network, you need to install a signal analyzer on a server connected to your network. This will access all the wireless APs in your business and detail the channels in use plus provide measurements of traffic volume as it occurs.
