Since technology is evolving day by day, interesting new developments are becoming a part of our lives. From the change of network to smart homes, we are now living with impressive technological achievements. Wi-Fi heat mappers are just one more piece of software that can help us make life in this highly connected world simpler.

Few people have even heard the term Wi-Fi heat mapper as it’s not that widely used just yet, but it’s a relatively simple piece of software that, like its name says, generates a Wi-Fi heatmap. This allows you to analyze your Wi-Fi coverage, performance, and signal strength.

How Does It Work?

A Wi-Fi heat mapper takes readings of Wi-Fi signal strength from different locations in the Wi-Fi coverage area, performs in-depth data analysis, and provides a Wi-Fi heatmap to help you analyze and monitor the performance of your Wi-Fi.

With this technology, you can identify the dead spots, the areas where the Wi-Fi signals are weak, and the areas where the signals are strong, as well as the possible interference from various Wi-Fi devices and networks.

High-quality software tools like NetSpot record signal strength while you’re moving through the coverage area and stopping at various locations to take a series of measurements. With these measurements, a heatmap is created and overlaid on the map of your workplace or home. This is especially important if your workplace is digital and requires the use of a B2B marketplace.

How to Create a Wi-Fi heat map?

If you want to create a useful Wi-Fi heat map, you need an accurate map of the area that your Wi-Fi covers. The Wi-Fi heatmap will be overlaid on the spatial map you provided. This means that you need a comprehensive map of your home or workplace.

It is important to have an image file of the area for the heatmap. If you don’t have it, you need to create the one before proceeding. The map should include all doors and walls, levels, and stairs.

You may already have floor plan drawings you can scan and use. Otherwise, you can get a copy of your building plan from the county clerk’s office. Alternatively, you can even draw a perfect plan for the area. It’s not that hard if you have the right tools. 

Comprehensive apps like NetSpot include built-in drawing tools that allow you to create maps from scratch. The baseline image must be in one of the following formats: GIF, JPEG, PNG, TIFF, or PDF.

When using PDF, you can only use the first page of a multi-page document. Use black and white images with a white background. If your map is large or has a very high resolution, you might have to add the map piece by piece. Most heatmapping apps support the maximum size of 3000 x 2000 pixels.

Procedure to Enhance Your Wi-Fi Heatmapper

Sometimes, it gets difficult for companies to track the performance of their sites. For instance, a poor internet connection will definitely affect B2B trade leads, which is a nightmare for a marketer.

Below are some useful steps that can help you enhance the heat maps and keep your Wi-Fi running smoothly:

  • Where no color is displayed, simply eliminate the areas so that you may not get the weak signals.
  • Check the direct line of sight when analyzing the dead zones. Simply reposition your router to avoid such obstacles.
  • You can also use a Wi-Fi booster when repositioning is not possible. It increases the signal strength in isolated or distant areas.


If you want to make sure your Wi-Fi heat maps are clear and useful, you should opt for simple procedures. You just have to know the elements and the basics of networking to achieve the results you need. Since Wi-Fi is really important in our lives, we need to get the best signals so that we can make use of everything that needs internet connectivity.
