10 Best Wireless Scanning and Analysis Tools (Windows, iOS, Android)

Wireless scanning and analysis let you “see” wireless networks, providing network administrators with the data they need to keep them operating at their peak. It is said that knowledge is power and this seems to be particularly true of wireless networks. Perhaps it is due to their “invisible” nature but it seems that they are often a mysterious beast that no one really knows. In today’s post, we’ll have a loot at what wireless scanning and analysis is and what tools are available to assist.

We’ll begin our discussion by explaining wireless scanning and analysis to the best of our abilities. Next, we’ll discuss the tools that can be used for that specific purpose. We’ll then pause briefly to discuss wireless heat maps which, although they are very different from wireless scanning and analysis tools provide much-needed assistance when deploying wireless networks. Finally, we’ll get to the core of the discussion and review some of the best wireless scanning and analysis tools, first for Windows, then for iOS, and finally for Android.

Wireless Scanning And Analysis Explained

Wireless scanning and analysis is a rather broad topic. Put simply, any tool that can be used to analyze Wireless traffic, data, and/or signals can be classified as a wireless scanning and analysis tool and there is a multitude of such tools with widely different feature sets. It is, therefore, somewhat complicated to explain exactly what they are as every developer of these tools seems to have its own idea of what it is or what it should be. In its most basic form, a wireless scanning and analysis tools is a piece of software that allows you to “see” wireless networks and/or their traffic.

The most basic of these tools will simply list what SSIDs are available in a given space and, most of the time, the strength of each SSID’s signal. Better tools tend to go further and they can, for instance, identify a source of interference that might be hindering your WiFi connection. They are very useful diagnostic and planning tools. Wireless scanning and analysis tools collect data about all wireless networks they can find and display that information in a useful manner. So go even further and can capture and decode wireless network traffic

While the manner in which data is presented is probably where there are the most differences between wireless scanning and analysis tools, most of them have some sort of visual display representing the different wireless networks. Others will present data in a table format.

There are basically two ways that wireless scanning and analysis tools operate. Some simply capture radio signals emitted by WiFi access points. Others connect to access points using SNMP or some other mean and read their operational data and metrics. And of course, the best ones combine both techniques and offer the greatest level of detail.

About Wireless Scanning And Analysis Tools

The reasons why one needs wireless scanning and analysis tools are pretty much the same as those which justify the need for any network scanning and analysis tool. First and foremost, they help you keep a watchful eye on what’s going on. They also are very useful in assisting with troubleshooting issues with your wireless networks.

Let’s say, for instance, that your users are complaining of frequent slowdowns or disconnects on the WiFi network. There’s usually a simple explanation to that: something—many times another WiFi network—is interfering with the operation of the network. This is exactly the type of issue that a wireless scanning and analysis tool can help you troubleshoot quickly. For instance, I’ve once used them to discover that the next-door tenant in the office building where our offices were had a much more powerful WiFi network than ours operating on the same channel. Once the tool helped me quickly identify the problem, I just had to reconfigure my WiFi access points to use another channel and the issue was solved.

Another use for wireless scanning and analysis tools is to measure the radio signal distribution throughout your location, be that a home or an office space. Wireless network signals are radio-signals which, although they can—to a certain extent—pass through walls, some building structures will block them. Perhaps not completely but enough to attenuate them beyond reliable usability. With a wireless scanning and analysis tool, you can walk through the space to find weaker spots or even dead spots with no coverage at all. If you’re planning on expanding your WiFi network, a wireless scanning and analysis tool will help you determine where to add the new access points for the best possible coverage.

WiFi Heat Maps In A Nutshell

Another very useful tool for wireless network planning is one that allows you to build WiFi heat maps. In a nutshell, a WiFi heat map is a visual representation of how your WiFi access points radiate their radio signals. It will show you where the signal is the strongest and where it is the weakest.

Heat map software tools are often stand-alone tools. They are separate from wireless scanning and analysis tools and they usually rely on polling data from your existing infrastructure to build the actual heat maps. They will often let you import a floor plan of your space where you indicate the location of the access point and the different construction materials used throughout the office. The software then interrogates the access points and builds a visual representation of the signal distribution over the floor plan.

Many suppliers of enterprise-grade wireless networking equipment offer some form of heat map tool but one of the best is a vendor-agnostic product from SolarWinds aptly called the SolarWinds Heat Map. It is part of SolarWinds’ flagship product: the Network Performance Monitor–or NPM–a suite of much-useful network management tools. Starting at just below $3000 the tool might not be within reach of everyone but it gives you much more than just heat maps. You can find all the details about the SolarWinds Network Performance Monitor by visiting the SolarWinds website.

A tool such as the SolarWinds Heat Map will let you create custom wireless heat maps that can help you find weak dead zones where there’s poor or no connectivity. It polls your access points to read their signal strength metrics and can indicate the quality of the connection at any location. The tool lays the heat map over a floor plan of the network’s location to give you a real physical overview of the situation.

The Top Wireless Scanning and Analysis Tools For Windows

We’ve finally managed to get to the good part of this post where we’ll be reviewing some of the very best wireless scanning and analysis tools. We’ll start off with some tools that run on the Windows platform. After all, this is still the most common OS used by network administrators. And it is also the platform for which you’ll find the best wireless scanning and analysis tools. Let’s review them.

1. SolarWinds WiFi Monitor 

SolarWinds, the same vendor who brought us the Heat Map and Network Performance Monitor tools mentioned earlier is also well-known for making some of the best network management tools. One of these tools is called the SolarWinds WiFi Monitor. And just like the SolarWinds Heat Map, it is part of the Network Performance Monitor package.

The SolarWinds WiFi Monitor is one of the best you can find. It will discover and monitor your wireless access points and add automatically them to the Network Performance Monitor. The tool will also build heat maps. Well, it’s actually the Heat Map tool described above that will take care of that as both the WiFi Monitor and the Heat Map are components of the Network Performance Monitor.

But more than anything, the SolarWinds WiFi Monitor will let you monitor your wireless infrastructure. The SolarWinds Network Performance Monitor Wi-Fi monitoring features will let you set alert, it will monitor your infrastructure and it will create reports on many aspects such as IP addresses, device type, SSID, channels used, and the number of clients currently connected. Client details include client name, SSID, IP Address, MAC Address, Received Signal Strength Indication (RSSI), time connected, data rate, and bytes received and bytes transmitted.

Like with most SolarWinds software, a free 30-day evaluation version of the Network Performance Monitor—including the WiFi Monitor and Heat Map tools—can be downloaded from SolarWinds’ website.

2. NetSpot

Our next entry is a great little tool called NetSpot. It was originally created for the Mac OS platform but the tool has since been ported to Windows.
