Enterprise WiFi Spectrum Analyzer For Windows 10, Mac, iphone, ipad and Android considered:

1. Metageek Wi-Spy DBx
2. Oscium WiPry 2500x
3. RF Explorer WiFi Combo
4. Airmagnet Spectrum XT
5. Triplett WiFi Hound

What is a WiFi Spectrum Analyzer ?

It is a well known fact that WLAN interference should be found and mitigated for WLAN optimization activities to be fully effective. 2.4 Ghz and 5 Ghz WiFi frequencies are congested in most of the office locations. Features of WiFi 6 standard tries to address many of the existing pain-points of WiFi communications.

In fact the upcoming WiFi 6E (6 GHz WiFi) will be the best thing to have happened for interference mitigation in a very long time. The High Efficiency(HE) 802.11ax standard combined with a freshly unlicensed 6 Ghz frequency band would relieve a lot of indoor interference worries for Enterprise customers, at least in the early days.

But in any frequency band externally induced interference cannot be ignored by IT teams.

Operating frequency based interference is generated from 2 types of sources:

1. WiFi signals from neighboring WLANs and other 802.11 sources, and

2. Non-WiFi signals from sources like cordless phones, wireless CCTV devices, microwave ovens, bluetooth enabled devices etc.

Various WiFi site survey tools are used to inspect wifi networks and wireless interference affecting them. For understanding interference from neighboring WLANs and 802.11 sources, WiFi heatmappers are used. WiFi heatmappers use specialized WiFi adapters or the internal WiFi cards of survey devices like laptops/tablets/mobile phones to capture and analyze WiFi interference in a location. Many popular heatmapping tools are available from top wireless site survey OEMS for this purpose.

However, to specifically find and analyze non-WiFi interference, a WiFi site survey tool called WiFi spectrum analyzer is used. WiFi spectrum analyzer is a wireless spectrum analyzer that inspects the OSI layer 1 (Physical layer) of WiFi networks. This is achieved by using specialized wireless signal processors that are capable of capturing and analyzing data from this layer. Although, data from OSI layer 2 is also captured for analysis purpose.

WiFi Spectrum Analyzer Measurements

Spectrum Trace Graph

Spectrum trace graphs provide a live measurement/ trace of maximum strengths of different signals operating in the selected frequency range. The signal strength is measured in dBm (decibel-milliwatts). In a sample measurement shown above, the frequency is plotted on x-axis and signal strength on y-axis to display captured signals.

The signal strength gives a fair idea about the proximity of signals from the measuring devices. Stronger the signal, closer is the source. Hence when moving around with a spectrum analyzer, focus is given to locations where interfering signals are found to be higher/maximum as rogue signal sources can be found nearby.

A continuous hunt for increasing signal strengths, combined with physical investigation of the area would reveal the interference source.

Spectrogram (Waterfall Graph)

The waterfall graph (Spectrogram or spectral waterfall graph) provides a rolling timeline view of signal strengths measured in a frequency range. In the selected band, frequencies with highest signal strengths are brightly colored for easy understanding. Different color shades are used to mark other frequencies corresponding to varying signal strengths. Through such coloration, the distribution and variation of energy across the selected frequency bands can be easily understood for a selected period of time.

When viewed over a reasonable time span, spectrogram gives a clear snapshot of the frequencies where continuous or intermittent energies are present. WiFi signals appears in bursts, thereby showing a scattered pattern around the channel frequencies. But non-802.11 interference from many known non-radio sources have patterns of constant signal strength (high duty cycle) around a frequency range. This can be seen as a continuous line or pattern as shown in the sample image above.

When such a spectrogram is recorded over a longer duration, any sporadic signal bursts can also be easily identified. By simply looking at the overall waterfall recording and noting the frequencies with sudden short color changes, such interferers can be found and focused on for further analysis. This will help immensely in identifying noise sources that have low duty cycles.

All this information will help to identify the WiFi channels affected by interference in a work space. This will in-turn help the Enterprise IT teams to take corrective action like WiFi channel management, interference mitigation etc.

Some WiFi spectrum analyzer devices also show the waterfall graph based on WiFi channels. They clearly mark out the affected channels using bright colors. This will help to quickly identify the affected WiFi channels, leading to optimization efforts.

Signal Density Graph

Signal density graphs give cumulative signal strength measurements. It is basically the summation of all the live spectrum trace measurements. The signal strengths that occur frequently are more brightly colored. Infrequent signals are denoted with different colors. Such color differentiation helps a surveyor to quickly understand the spectrum characteristics of an area.

Density graphs can give a quick reckoning of unusual signal strengths noted in an area. Any anomalies in the signal strength can be easily understood by deviations from the general signal density noted.

This again can help to re-confirm the frequencies where non-802.11 signals operate so that the WiFi channels can be managed accordingly and the interference can be mitigated.

In some products the spectrum trace and density graph are combined into a single view.

Interference Pattern Matching

Interference signal pattern matching is provided by some WiFi spectrum analyzer manufacturers.

Many types of non-802.11 interference have recognizable signature patterns that can be distinguished in the measurements.

By comparing a known signal pattern with a live signal graph, it can be quickly understood whether the interference noted in an area comes from a particular type of non-802.11 source. If the signal pattern matches, then it would simply mean that a particular interference causing device like wireless CCTV or cordless phone is operating in the survey area. Now since the device type is known it can be easily searched, identified and neutralized.

Also signal pattern matching helps to cut down the time taken to find multiple interference sources operating in a WLAN area. Various signal patterns can be compared one after the other till the patterns match with the live signals. This process will greatly cut the time spent hunting for different interference sources in a highly congested area.

WiFi Signal Analyzer

A WiFi Spectrum Analyzer also captures 802.11 WiFi signals for analysis. That is, going above the OSI Layer 1 to capture and analyze WiFi radio signals. This is important because the WiFi signals and non-WiFi signals need to be compared and analyzed together for quicker resolution of issues. Usually, basic information like signal strength, density graph, channel utilization, channel history, network names (SSID) etc are captured.

WiFi Spectrum Analyzer Comparison Chart (April 2020)

Overview of products considered for comparison

Metageek

A popular name in the WLAN Signal Analyzer industry, their solutions have been well tested in the market and proven to be effective in identifying non-802.11 interference in the work areas operating WLAN radios.

Metageek’s solutions consist of both hardware and software. The hardware solution offered by Metageek for spectrum analysis is a USB based spectrum analyzer called Wi-Spy DBx. This can be used to simultaneously analyze both 2.4 GHz and 5 GHz WiFi spectrum for interference using their latest analyzer software. There is also a 2.4 GHz version of Wi-Spy, which could be available with local distributors. It is not showcased on the Metageek website right now (April 2020).

Wi-Spy DBx pairs with a PC software called Chanalyzer, which is used to analyze the data captured by Wi-Spy. Chanalyzer captures WiFi data from the internal* WiFi cards of the laptop that is used for the analysis work. ( *external USB WiFi adapters needed when used on windows virtual machines in Macs)

Chanalyzer provides detailed spectrum data like density graphs, waterfall graphs, pattern matching (Fig2), channel utilization graphs etc. It also provides intuitive analysis of data captured from WiFi devices in the area.

Chanalyzer has an option to connect remotely to a Cisco CleanAir enabled access point and conduct a spectrum analysis. It works with Cisco access points in local, monitor or SE-Connect modes. The model numbers with which this Chanalyzer feature will work has been specified by Metageek.

Metageek also provides an optional dual band directional antenna attachment to Wi-Spy DBx that can be used to replace the standard omni-directional antenna on the analyzer. This directional antenna helps to reduce the effort spent in physically locating the interference sources. There are specific live graphs available in the Chanalyzer that work together with device finder antenna towards this effort.

Metageek has a mobile phone based dual band spectrum analyzer solution as well, called Wi-Spy Air. This works on standalone AAA batteries and connects to Android or iOS devices through their free Air Viewer App that only works when Wi-Spy Air is connected. An on-board WiFi chip set allows to measure WiFi related information like retry rates, actual data rates, connected client count, channel utilization etc.
