WiFi Advisor™
The first wireless LAN analyzer built
for installers at all skill levels
End users depend on WiFi to reliably deliver premium services
such as video OTT and IPTV to endpoints throughout their
homes. However, non-WiFi interference, competing WiFi
networks and channels, and the exploding number of WiFi
clients often hinder WiFi performance. As a result, 50% of all
trouble calls are now WiFi related. Technicians who install and
maintain WiFi in the home require robust installation methods
and rapid, intuitive troubleshooting capabilities that even a
WiFi novice can use.
The WiFi Advisor consists of a host application (running on an iPad, Android tablet, or the
Viavi OneExpert platform) and one or more WFED-300AC test devices. It is the first test
solution to meet the needs of technicians at all skill levels. Providing a new, visually rich
approach to testing, its intuitive capabilities enable rapid characterization, optimization, and
troubleshooting of highly changeable and vulnerable home WiFi networks. It shows a wholehome view of real WiFi performance margin and can deliver easy-to-understand information
directly to the end customer.

Consolidate Your Test Investment
The WiFi Advisor is fully integrated with the Viavi OneExpert
broadband-to-the-home test platform. This power combination
Model 1

There are two ways you can consolidate your toolset and
minimize both OpEx and CapEx:
Access point
yy Control a single WiFi Advisor from your OneExpert to do BSSID,
spectral, and channel view testing. This lets you avoid purchasing
a separate tablet device to host the WiFi Advisor application and
reports. The OneExpert hosts the WiFi Advisor application.

yy Conduct two-ended testing with a single WiFi Advisor, a tablet,
and your OneExpert. Consolidate your tool set and eliminate the
need for two WFEDs.
Troubleshooting and Optimization
Using a single WFED-300AC device, users can quickly visualize, optimize, and troubleshoot WiFi networks using the Smart Channel Wizard and
the complementary BSSID, Channel, and Spectral views. The SmartChannel Wizard summarizes the KPIs and the health of the selected BSSID
and the channel in which it resides. The summary will help novice uses and guide them to a resolution for each metric that is not optimal with
practical optimization guidance. The Wizard sees beyond access point occupancies into the client detail of the entire customer network and the
clients or any co-channel-sharing networks.
For example, the SmartChannel Wizard figure below shows high channel utilization and a high client station load. It recommends that the
channel be changed to avoid the crowd and improve the experienced speed and throughput.

BSSID view provides quick visibility into active wireless networks and identifies the least-crowded channel to use for your access point. The
application plots each in-range BSSID by channel and signal strength and identifies access points sharing a channel (co-channel interferers) or
overlapping a channel (adjacent interferers) for each channel in the band. It also displays continuously-updated trend graphs of BSSID signal
strength, noise, and channel utilization as the installer moves through the site.

Channel view finds the best channels for an access point by showing
utilization, noise, co-channel interferers, adjacent channel interferers,

and an overall channel score for each channel. Simply pressing the
Best Channels button lists the top three channels for each channel
width within the selected band.
trouble calls
Actual Layer 3 throughput margin is the key factor for determining
the tolerance to changes in the WiFi environment. A high throughput
margin equates to a high WiFi network resiliency and a reduced
likelihood of trouble calls and repeat truck rolls. It is especially
important when your customer expects high QOE in video over WiFi.
Channel view shows best channels
Spectral view shows damaging RF interference with a real-time
spectral analyzer configurable by 802.11 band, channel, and channel
width. It helps find interfering signals by showing all RF energy
within a given channel/channel width of interest.
The WiFi Advisor shows real Layer 3 performance and determines the
sources of throughput loss throughout a site. And, it conducts whole
home performance testing either with or without the customer’s
access point. During the assessment, it lets a technician:
yy Determine the maximum packet throughput capacity for a WiFi
connection under test
yy Gain visibility into factors impacting throughput
yy Assess throughput margin relative to the configured service level
Spectral view shows interference within a channel
Site assessment analyze throughput and identifies slowdowns

if the end user wants to understand how a wireless set top box would
work outside on the patio, it’s a simple matter to add that location to
test results from all locations and all device profiles and creates a
highly informative report that sets proper expectations. It can be
e-mailed directly to the end user from the host application. The net
result is a standardized approach to WiFi testing that thoroughly
evaluates actual performance at each location of interest throughout
the site and provides highly informative, leave-behind information.
