Price: Free open hardware monitor portable wifi open source. Download: Free 7-day trial of Open Hardware Monitor Portable 50 WiSpy. It also works with additional hardware to capture packets from the air, from WiFi interfaces, Bluetooth, SDR, and more. The app supports both WiFi hareware, the 2.

And this tool is called the WiFi analyzer. It can take different forms and run on different platforms but they all have a common goal, provide some information about the status of a wireless network. Analyzers running on portable devices such as smartphones or tablets can be particularly interesting as they can be brought to any location for on-the-spot troubleshooting.

Monitoring wired networks is easy—kind of. Buth things are different with a wireless network. Monitoring wireless networks can mean different things too. On one hand, it could be the actual monitoring of airwaves to discover what signal is available and, more importantly, the relative level of desired as compared to parasitic or unwanted signals.

On the other hand, monitoring can also mean the capture and analysis of wireless access points operational parameters. Thing like signal strength, available channels, number of current connections, and a whole lot more can easily be gleaned by wireless analysis tools. The term WiFi Analyzer is quite broad and generic. Every maker of such software seems to have its own idea of what it is and what it should be. Some WiFi Analyzers go deeper and can identify a source of interference that might be hindering a WiFi connection.

Those tools are very useful as diagnostic tools. Some WiFi analyzers collect data about all WiFi networks they can find and display that information in a useful manner. Most WiFi analyzers boast some sort of visual display depicting WiFi networks. Others present data in a table format.

There are two general types of WiFi analyzers. Those which capture WiFi radio waves emitted by WiFi access points and those which connect to access points using SNMP or other means to read their operational parameter. The best tools combine both techniques, offering the greatest level of detail. The most common cause for that type of behaviour is simple, something—most likely another WiFi network—is interfering with the operation of the network.

A typical WiFi analyzer would let you let you quickly identify the source of interference. I, for example, have used them once to discover that the next-door tenant in an office building had a much more powerful wireless network operating Open Hardware Monitor Zabbix Query on the same channel as ours. Once the problem was clearly identified, fixing the issue was a simple matter of reconfiguring my WiFi access points to use another channel. Another use for WiFi analyzers is to measure the signal distribution over its coverage area, be that within a house, an office or even outdoors.

Wireless networks use radio-signals and, although they can go through walls—to a certain extent—some building structures can block them perhaps not completely but enough to attenuate them beyond reliable usability.

A WiFi analyzer running on a portable device such as a tablet or smartphone can be used to walk through an area and identify weaker spots or spots with no coverage at all. Talking about wireless network planning and coverage, another super-useful tool is called a WiFi heat map.

A WiFi heat map is a visual representation of how each WiFi access points radiate its radio signal. It will show you where the signal is the strongest and where it is the weakest.

Some WiFi analyzers do include that functionality either built-in or as an add-on and many heat map tools are also available as stand-alone software. Those tools typically rely on polling data Open Hardware Monitor Portable Java from your existing wireless access points and controllers to build the heat map.

However, most will also support manual data entry, a useful feature when planning a future implementation. Most will also let you import a floor plan of your space—or create one—where you indicate the location of the access points that the software will use to build a visual representation of the signal distribution as an overlay on top of the floor plan. Most suppliers of enterprise-grade WiFi equipment offer some form of heat map tool but one of the best is a vendor-neutral product from SolarWinds aptly called the SolarWinds Heat Map.

This tool will poll your access points to read their signal strength and other important parameters and indicate the quality of the connection in any location. The tool will lay the heat map on top of a floor plan of your location which you can either import or create within the software, giving you a physical overview of the wireless signal propagation. Luckily, Windows is the running platform of the best tools available. SolarWinds, the same company which brought us the Heat Map software mentioned above is well known for producing some of the best network management tools.

And SolarWinds is also famous for its free tools, each addressing a specific need of network administrators. Two examples of these free tools are a simple TFTP server and an excellent subnet calculator. This tools will discover your wireless access points and add them to the SolarWinds Network Performance Monitor so they can be monitored.

The SolarWinds Wi-Fi Monitor will let you set alerts, it will monitor your infrastructure and it will create reports on several parameters such as IP addresses, device type, SSID, channels used, and the number of clients currently connected. NetSpot is another one of the best WiFi analyzers on the market. Originally created for the Mac platform, the tool has been ported to Windows.

The tool collects operational data from you access points including channel width, MAC address, signal quality, and even network encryption providing some of the best visibility over the operation of your wireless network. When it comes to features, it leaves nothing to be desired. It will, for instance, help you assess WLAN interference. Another strong point of this tools is its reporting engine.

It combines ease of use with an unprecedented depth of available information. One great thing about NetSpot is that it is about as good for home users as it is the professional network administrators. And as a matter of fact, it is available in two versions. The Home edition is priced below 50 dollars while the Professional edition sells for around dollars. Acrylic Wifi is considered by many to be the best free WiFi analyzer for windows.

This wireless network scanner will perform detailed security and coverage analysis for WiFi networks in a very short time. It is a fast tool. Log in or register to post comments.
