NetSpot can help you analyze your WLAN interference to determine the best WiFi channels to be used by your access points. A professional report can easily be assembled that provides a complete analysis of your wireless network.
If you could see wireless network activity with your eyes, you would most likely be surprised by how many wireless signals are in range. In densely populated areas, the demand for WiFi connectivity is so large that it’s causing major issues with signal interference, which can lead to slowdowns and connection drops.
WiFi analyzer apps, also called a WiFi channel analyzers, make up for our inability to see wireless signals by displaying all important information about them in a visually accessible manner. With a capable WiFi analyzer, free or paid, you can collect information about both 2.4 GHz and 5 GHz signals and instantly transform the collected information into easy-to-understand graphs, charts, and heatmaps.
A WiFi analyzer lets you see wireless activity in your area by examining the radio spectrum in which WiFi signals are broadcasted. Most modern routers use two frequency bands: the 2.4 GHz band and the 5 GHz band.
The 2.4 GHz band has been in use for much longer than the 5 GHz band, which is why this chunk of the radio spectrum tends to be crowded in most areas with a higher population density. It does, however, provide a larger coverage area than the 5 GHz band, whose main advantage is a higher data rate.
By analyzing the 2.4 GHz and 5 GHz bands, you can gather information about all currently broadcasting access points that are withing the range of the device on which you run your free WiFi analyzer, such as a Windows laptop or MacBook.
The best free WiFi analyzer apps can then help you make sense of the gathered information, allowing you to use it for a variety of different purposes, some of which we discuss later in this article. Some free WiFi analyzer Windows and Mac apps can even zero in on a specific network and visualize its coverage on a map by putting together information gathered from different parts of the covered area.
To use a WiFi analyzer app, you don’t need to be an expert on wireless networks. Most WiFi analyzer apps are actually used by regular people who want to maintain connection quality and quickly identify problems that are preventing them from watching videos on the internet, playing online games, browsing the web, or even sending email messages.
Of course, WiFi analyzer apps are also used by professionals whose job is to set up complex enterprise networks and seamlessly cover multiple floors with a strong WiFi signal. What’s important, however, is that all features of modern WiFi analyzer apps like NetSpot are accessible to beginners and pros alike.
Even if you’re happy with the performance of your WiFi network, you should consider using a WiFi analyzer app to see if there’s room for improvement. There could be small areas of signal weakness, also known as dead zones, that you’re not aware of because they cause problems only sporadically.
WiFi analyzer apps like NetSpot show a wealth of useful information to help you troubleshoot and improve your network's coverage, capacity, and performance. Here’s a small sample of what NetSpot can gather:
Equipped with all this information, you can easily troubleshoot complex WiFi issues and ensure that you’re getting the best coverage and performance possible.
Open NetSpot and upload a floorplan of the area you wish to analyze.
Analyze the resulting Signal-to-Noise Ratio heatmap that is displayed. Look for areas of dark blue and purple. These are spots where coverage may be inadequate.
Adjust the Signal-to-Noise heatmap if desired, by changing the min and max signal variables on the sliders in the visualization config popup, as well as the AP detection proximity.
View the Signal-to-Noise Ratio heatmap by specific network, if desired. Go to the control panel to the left of the heatmap and uncheck the boxes next to the names of the networks you do not want displayed.
Analyze your Wi-Fi network by specific channel, if desired. Click on Configure > Select Networks by Channel at the bottom of the control panel to select the desired channel.
Export your Signal-to-Noise Ratio heatmaps to PDF by clicking the Export button on the top of the NetSpot window.
Continue to analyze your wireless network by selecting other reports from the drop-down menu in the lower toolbar of the NetSpot window. Other Wi-Fi analyzer reports include Signal Level, Signal-to-Interference Ratio, Noise Level, and Quantity of Access Points, Download and Upload rates (PRO), Wireless Transmit Rate (PRO) and Troubleshooting (PRO). Export additional heatmaps as needed.
NetSpot is the best free WiFi analyzer app for Windows and macOS because it makes professional WiFi analysis accessible to anyone. With the desktop version of NetSpot, you can instantly collect all important information about nearby WiFi networks and create interactive heatmaps with detailed coverage information.
Both the Windows and macOS version of NetSpot can be downloaded and used for free with certain limitations. Paid licenses are available as one-time purchases, so there’s no reason to worry about recurring subscription fees.
Using NetSpot on your smartphone is just as easy as using it on a laptop — no special knowledge required.
More about the NetSpot WiFi analyzer Windows app.
In order to analyze your WiFi with NetSpot start by uploading the floor plan to the app and perform a site survey. The heatmap that you get after the survey will help you visually analyze your wireless signal and see where the changes might be needed. Your heatmap can be exported into file for further usage.
When analyzing the Signal-to-Noise Ratio heatmap you need to look for areas of dark blue and purple. These are the possible areas with insufficient coverage.
With NetSpot you can build a comprehensive heatmap of your WiFi area. The heatmap visually shows you the areas where coverage is inadequate. 12+ types of visualizations help you analyze your coverage by different parameters. You can analyze heatmap by specific network or WiFi channel.
NetSpot stands out as the best free WiFi analyzer app for Windows, Mac, and mobile devices because it combines professional features with an easy-to-use user interface, making it suitable for regular home users and network administrators alike.
Yes, there are many free WiFi analyzer apps that can be used to analyze both 2.4 GHz and 5 GHz signals, but not all of them are equally capable or easy to use. Some may even give inaccurate readings, which is why you should always use the best free WiFi analyzer app available for your operating system.
With so many WiFi analyzer apps available, finding the best one is far from easy. One WiFi analyzer app that has received countless raving reviews from real users and professional reviewers alike is NetSpot, and you can download it free of charge for Windows, Mac, and even mobile devices.
A WiFi analyzer gathers information about wireless activity in 2.4 GHz and 5 GHz bands, allowing you to see all broadcasting access points in your area and analyze their configuration and status. This can be useful when troubleshooting various network problems or optimizing a network to achieve the best performance and coverage possible.
