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

wireless heat map software

Marc Wilson

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?

What is a Wifi 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.

Here's 6 of 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.

1. SolarWinds Wifi Heat Map

solarwinds

SolarWinds Wifi Heat Map comes with the Network Performance Monitor “NPM,” which is an advanced network and performance monitoring software for on-premises, hybrid, and cloud infrastructure.

With the Wifi HeatMap from Solarwinds, you can create custom heatmaps. Start with a manual site survey of the wireless signals so that the tool can record it on the surface of a blueprint or layout. NPM with Wifi Heatmaps will poll the signal strength from clients and APs and generate dynamic Wifi heatmaps.

Key features that are Important for this Tool!

  1. Generate automatic Wifi heatmaps.
  2. Troubleshoot dead zones.
  3. Find and track the location of mobile clients.

With the map, you can visualize wireless coverage, find where are the dead zones, and optimize them accordingly. The tool collects information from APs and their clients and shows their signals in a colored format. Hot (red), represents where the signal is strong, and cold (blue) represents where the signal is weak. The tool is also capable of finding and tracking the location of mobile devices within the map (as shown in the screenshot below).

NPM with Wifi Heatmaps is only supported by Windows Server 2008 R2 SP1,  Windows Server 2012 and 2012 R2

2. Acrylic Wi-Fi Heatmaps

acrylic

Acrylic Wifi Heatmaps is a site surveying and Wifi planning tool. It is designed to provide WLAN coverage mapping and RF analysis. It can analyze the 2.4 and 5 GHz frequency bands and supports active/passive site surveying.To start a site survey, define the location of the wireless signals. Upload your floor plans or perimeters of a geographical area into Acrylic Wi-Fi Heatmaps. If you don’t have a blueprint, you can create it within the platform. You can draw walls, furniture, and even identify the materials to make it more real.

The tool will begin to measure Wifi signal levels, scan for devices nearby (including APs and connected clients), and capture Wifi traffic. With all this information, the tool can create detailed maps showing coverage of each AP.

NetSpot is a comprehensive wireless site survey, Wifi analysis, and troubleshooting application. It is designed for a wide variety of scenarios, from small home WLAN users to large-scale wireless deployments. NetSpot can help you improve the wireless security standpoint by running an advanced analysis. It can also help optimize the Wifi signal strength via heatmaps.

To start a site survey with NetSpot, you need to upload your office plan or area layout. Indicate your location on the office plan, and the tool will begin to calculate the wireless coverage. As you move around with your site survey device, Netspot will continue to record data of the signals received in the area, and finally, create a heatmap.

The heatmap will give you a visual representation of where the signal is strong and where it is weak. It will also help you to improve coverage, enhance wireless security, and avoid dead zones.

NetSpot has the following features (and a lot more):

  • A built-in mapping tool. If you don’t have an area layout, you can create one right there.
  • Automatic heatmap. Once you do a manual site survey, the tool will generate a heat map automatically.
  • Discover Mode. Automatically collects information about its surrounding Wifi networks.
  • Real-time Charts. It shows charts of signal level and noise in real time.

 

 

NetSpot is available for Windows and macOS.

Price:

NetSpot has the following pricing versions – Free, Home ($49.00), PRO & Enterprise (starts at $149.00). NetSpot also offers two versions of the tool through the App Store with a difference in price and features. The Scanner ($7.99) and Reporter $39.99.
