About the Wireless LAN Analyzer
The Wireless LAN Analyzer provides a complete, multi-dimensional map of real
WiFi performance, highlighting margin and resiliency of WiFi connections at
multiple locations within a site (versus a simple signal strength icon). It includes
intuitive tools to quickly optimize and troubleshoot the in-home WiFi network. After
the test, it provides valuable performance information to the end-user to help
reduce unnecessary trouble calls and repeats.
Architecture
The system architecture of the Wireless LAN Analyzer solution includes the
following:
1 The WFED-300AC WiFi Advisor test device. Each WiFi Advisor contains an
802.11 radio, spectrum analyzer, and a network processor. The device is
responsible for performing tests requested by the iOS WiFi Advisor iOS
Application.
2 The WiFi Advisor iOS Application. This software runs on an Apple iPad
(iPad 2 or newer, with iOS 7.x.x or newer).
The application allows the user to set up WiFi tests, communicates test setups to
the WFED-300AC WiFi Advisor test device(s) over Bluetooth, manages test execu-
tion, displays test results, and enables administration of job or work ticket related
information.
NOTE:
At least one WFED-300AC test device is required for single-ended troubleshooting,
and two WFED-300AC test devices are required for Site Assessment testing.

The single-ended troubleshooting test includes the following:
•Quick, visually intuitive assessment of critical WiFi network factors reduces
troubleshooting time
•Spectral insight within the same tool allows identification and isolation of
common, non-802.11 interferers
•Expert recommendations helps minimize the time spent to effectively opti-
mize the network and reduces likelihood of repeat calls
The following procedure describes how to troubleshoot a single connection on a
network.This test is typically run if the service is not working properly.
To troubleshoot a single connection
1 Bring the iPad and WiFi Advisor to the location experiencing problems.
2 Open the app on the iPad.
3 Select Single-Ended Troubleshooting.
4 Choose which WiFi Advisor device to use for the test.
If you have previously used a WiFi Advisor device with this iPad, it appears in
the list of devices. If it does not appear, you may need to register the device
with the iPad and pair to it. See “Connecting a WiFi Advisor for the first time”
on page 12 and “Registering and unregistering devices” on page 12.
5 Select a result tab at the top: BSSID, Channel, or Spectral.

This provides a visual representation of overlap in the channels to help identify
problem spots.
The BSSID graph area shows each visible BSSID by channel and signal strength.
This view is useful for understanding an existing Access Point’s channel configura-
tion and signal strength or for determining which channel to select for a new AP to
be placed within the environment.
To toggle between 2.4GHz band and 5GHz band, touch the band toggle switch in
the upper left of the graph.
The BSSID List view in the right pane provides a listing of all detected BSSIDs along
with their channel setting, current signal strength, and MAC address. To change the
order of the list, tap 123 (sort by channel) or ABC (sort by name). To view more
details of a particular BSSID, touch the desired BSSID.
From the BSSID Details menu, touch Trend Graphs. Trend graphs show RSSI,

The Utilization graph in the top pane shows the channel utilization for all channels
in the selected band. Touching a bar within the graph highlights the bar for that
channel (the blue bar will turn green) and the “BSSID List” changes to the Channel
Summary which includes values associated with that particular channel.
The Noise graph in the bottom pane displays the noise per channel.
Touching the band toggle switch in the upper left of the graph toggles between
2.4GHz band and 5GHz band views.
As in the BSSID view, the BSSID List view in the right pane provides a listing of all
detected BSSIDs along with their channel setting, current signal strength, and MAC
address. To change the order of the list, tap 123 (sort by channel) or ABC (sort by
name).
Touching a specific BSSID from the BSSID list configures the Utilization bar graph

particular channel which includes the channel score, the channel utilization, noise,
the BSSIDs resident in the channel, and the BSSIDs that are overlapping (adjacent
to) that channel.
Touching Best Channels in the top right area of the Utilization graph displays a
table that identifies the current top 3 best channels based on channel width for the
band being viewed. Touching anywhere on the screen closes the table.
Spectral results
The Spectral results, shown in Figure 10, provides a real-time spectral analyzer
configurable by 802.11 band, channel, and channel width. It is helpful for finding
signals that interfere with 802.11 networks by showing both 802.11 and non-802.11
RF signals within a given channel of interest.

The Spectral results screen has 3 main areas:
•The spectral graph area, where the real-time spectral data is displayed
•The controls area, where the user can configure the spectrum analyzer
ranges and modes
•The BSSID List / Channel information pane
Navigating the Spectral result screen
As in the BSSID and Channel views, the BSSID List view in the right pane provides
a listing of all detected BSSIDs along with their channel setting, current signal
strength, and MAC address. To change the order of the list, tap 123 (sort by
channel) or ABC (sort by name). The BSSID list is not continuously updated while
spectral data is being displayed and is therefore labeled as SNAPSHOT as it repre-
sents a list of BSSIDs gathered over a finite period of time prior to turning on the
Spectral Analyzer.
Touching a specific BSSID from the BSSID Snapshot List configures the Spectrum
Analyzer to the channel(s) associated with the BSSID selected, and changes the
BSSID Snapshot view in the right pane to the Channel Details for that particular
channel which includes the channel score, the channel utilization, noise, the
BSSIDs resident in the channel, and the BSSIDs that are overlapping (adjacent to)
that channel. NOTE: This data is a snapshot. Live data may vary slightly.
The Spectrum Analyzer controls, located across the top of the graph, consist of the
following:
1Band toggle switch – selects 2.4GHz or 5GHz bands for analysis
2Channel bandwidth selector – selects the width of the spectrum analyzer:
– 20MHz
– 40Hz, or
– 80MHz (5GHz band only)
3Channel up (+) or down (-) – touch to increment or decrement the 802.11
channel(s) being analyzed
4Max Hold – turns the Max Hold trace on the spectral graph on or off. When
Max Hold is on, a blue line appears above the standard spectral line that
represents the peak value (in dBm) seen at each frequency point.
Chapter 3 Testing

WiFi Advisor Wireless LAN Analyzer User’s Guide
Page 24 22073751, Rev. 002 December 2014
5Clear – located under Max Hold, it resets the Max Hold trace and restarts the
measurement.
6Average – allows averaging of the real-time trace when on
7Number of Samples – select the number of samples to be used for averaging
of the real-time trace
8World view – shows all channels. Changing the channel bandwidth changes
how channels are represented in the world view.
To insert a vertical cursor within the real-time spectral plot, touch the graph where
the cursor position is desired. The cursor readout box in the upper left reports the
frequency at that position, in addition to the real-time and max hold signal levels at
that frequency. The cursor can be moved by tapping anywhere on the graph within
the channel width. By default, a cursor is located at the left edge of the view.
Troubleshooting Spectral measurements
The following are some common interferers that could show up in a spectral
measurement.
Microwave ovens can interfere with an 802.11 signal. They are most prevalent in
channels 10 and 11. If possible, it is a good idea to look at the spectral response
while the microwave is running to determine it’s impact.
Bluetooth devices appear as spikes and appear to “roll” through the spectral view.
They are fast moving and you may only see them occasionally. The systems are
designed to be interoperable, but Bluetooth will impact throughput.
Chapter 3 Testing
Assessing WiFi performance throughout a site
WiFi Advisor Wireless LAN Analyzer User’s Guide
December 2014 22073751, Rev. 002 Page 25
Channels can “bleed over” into adjacent channels. The width of the signal (due to
RF considerations) can affect nearby channels, as shown in Figure 11.
Assessing WiFi performance throughout a site
The general procedure for a Site Assessment test is:
1 Place one WiFi Advisor in close proximity to where the Wireless Access
Point (or Residential Gateway) will be installed.
2 Take a second WiFi Advisor along with your iPad to the location where WiFi
performance is to be assessed. The test thoroughly evaluates WiFi perfor-
mance between the two locations.
3 Move to the next location of interest and repeat the test to the Access Point.
4 Continue until all locations of interest have been performance tested.
5 If desired, the test results are saved to the active job or work ticket or associ-
ated with a new job. (See the “Managing jobs” section for more details
regarding work flow with job / tickets).
The two-ended site assessment test includes the following features:

Getting started
In order to get started with site assessment test, you must have two registered WiFi
Advisors connected over Bluetooth.
To get started
1 Launch the WiFi Advisor app.
2 Select Two-Ended Site Assessment.
Specifying settings
During Site Assessment test, up to five individual test profiles are configured that
are repeated at each location. The test profiles run sequentially at each location,
and always in the same order. Each Site Assessment configuration has a Primary
Profile, with up to four additional profiles, known as Secondary Profiles. Only the
Primary Profile is associated with Pass/Fail or Closeout testing. The Secondary
Profiles are informational, rather than Pass/Fail. At the beginning of the Site
Assessment, the Secondary Profiles can be enabled or disabled as a group. This
allows for rapid Site Assessment testing if only the Primary Profile is desired.
Step 1: Selecting devices
The first setting to specify is selecting which device is the access point and which
is the station.
Chapter 3 Testing

Troubleshooting Problems with Your WiFi Advisor
Please refer to the following table if your WiFi Advisor does not seem to be
performing correctly. If you still cannot solve your problem, please contact JDSU
Technical Assistance on 1-855-ASK-JDSU (1-855-275-5378) or by email at:
TAC@jdsu.com.
Problem Action
Cannot connect the mobile
app to the WFED-300AC – Check that Bluetooth is ON (enabled) on your iPad.
– Make sure that the iPad and WFED-3000AC are
within reasonable Bluetooth range of each other
(ideally 0 to 20 feet)
– Look at the number of Bluetooth devices in the
area. Three to four devices is a practical limit,
depending on the types of devices and profiles
used. Some devices require more Bluetooth data,
so they are more demanding than other devices.
Data-intensive devices may reduce the total num-
ber of devices that can be active at the same time.
If a Bluetooth device becomes slow to connect or
does not perform reliably, reduce the total number
of connected devices.
The WFED-300AC is
unresponsive (locked-up) – Press and hold the power button for 5 seconds.

WiFi Fundamentals
This chapter provides a general description WiFi and 802.11. Topics discussed in
this chapter include the following:
•“WiFi deployment” on page 50
•“Network standard” on page 50
•“802.11 specifications” on page 51
•“Spectrum Differences” on page 51
Appendix B WiFi Fundamentals
WiFi deployment
WiFi Advisor Wireless LAN Analyzer User’s Guide
Page 50 22073751, Rev. 002 December 2014
WiFi deployment
Successful WiFi service delivery is highly dependent on a vulnerable RF physical
medium that is dynamically shared, along with complex L2 (i.e. 802.11) and
supporting protocols. This makes installation of service a potentially complex task.
Reliance on simplistic installation methods that do not provide an indication of
robust service level margin can impact QoE (quality of experience) as the RF envi-
ronment / network changes, resulting in trouble calls, repeats and churn.
Inability to assess 802.11 performance and true throughput at critical locations
throughout the home leaves the end user guessing as to how the installed network
should perform, leading to trouble calls and truck rolls as the end user adds to /
modifies the WiFi network.
Network standard
The network standard uses RF (radio frequency) spectrum as the physical layer.
That means no wires, but can have issues with walls, mirrors and certain other
building materials. The network standard has protocols to handle some interferers,
such as:
•Co-channel (same channel) interferers can cooperate transmission (take
turns).
•Burst interference mitigation by delayed transmission
•Adjacent Channel interferers are an issue
•Non-802.11 interferers are a big problem because they can appear as 802.11
but do not adhere to protocols. Your 802.11 radio will wait to get the “ok” to
transmit, which may never come. It also can de-sensitize the receiver since
the packets may not be received, the transmitter will keep sending the
message “waiting for an acknowledgement”

802.11 specifications
802.11 is the “parent” of a family of Institute of Electronics and Electronic Engi-
neering (IEEE) specifications for wireless LAN.
The standard has undergone several revisions:
Spectrum Differences
Understanding the different spectrums and channel allocations can help identify
trouble areas.
2.4 GHz Spectrum
In North America, there are 11 channels, each 22 MHz wide. These channels
overlap, except for 1, 6 and 11. Thus, these channels are always preferred.
The rest of the world includes two additional channels (12 and 13).
Figure 16 provides a map of the channel allocation for the 2.4 Ghz spectrum. Indus-
trial, Science and Mechanical (ISM)” is the band that can be used by anything that

5 GHz Spectrum
A lot of these frequencies are used for satellite communications (low power). That
means to them, WiFi is the interferer. U-NII stands for Unlicensed National Informa-
tion Infrastructure and was set aside primarily for WiFi use. Most of the world uses
the spectrum from 5.18 – 5.835 GHz. Note that another ISM band exists here (cord-
less telephones, point-to-point radios, baby monitors).

This band can vary in a greater number of regions, as shown in Figure 18,
and.certain channels are designated as indoor use only or outdoor use.
The terms “Indoor” or “Outdoor” relate to output power restrictions on the radios.
