1. WiFi Advisor Wireless LAN Analyzer Overview

The WiFi Advisor Wireless LAN analysis solution is a test platform focused on the installation and
troubleshooting of resilient WiFi networks in the home. The solution includes the following system
elements:

1. The WFED-300AC test device. Each WFED-300AC 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. (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.)

2. The WiFi Advisor iOS Application. This software runs on an Apple iPad (iPad 2 or newer, with
iOS 8.0.0 or newer). The application allows the user to setup WiFi tests, communicates test
setups to the WFED-300AC test device(s) over Bluetooth, manages test execution, displays
test results, and enables administration of job/work ticket related information.

Revision 2.0.5 [e-mail]

1. Label your WFED-300AC with the letter designator of your choice from the sheet of ID

Labels provided. This label will be used during the registration process to provide a simple
method to identify test devices for use in the iOS application.

2. Ensure Bluetooth is set to ON in the Settings menu on your iPad.

3. Press the power button (Green) on the WFED-300AC to power the unit on.

4. Press and hold the blue button until the blue LED blinks continuously (about 5 seconds).

5. From the Bluetooth menu of the iPad, select the WFED-300AC from the list of devices to

pair it with your iPad, using the serial number to confirm identification of the device.

6. Launch the WiFi Advisor App on the iOS Device

7. Select Device Management from the Main WiFi Advisor menu (Home).

8. Tap “Register This Device”.

9. Enter a letter designator to match the physical label on the WFED-300AC.

Your WFED-300AC is now connected to your iPad and ready for use!
After the initial setup, you need only make sure Bluetooth is turned on for the iPad and that the
WFED is powered on. The WFED will connect automatically.

5. The Device Manager

Selecting the Device Management icon from the WiFi Advisor Home screen takes you to the
Device Manager. In this screen you can:

1. Register WFED-300AC WiFi Advisor Test Devices for use by the WiFi Advisor iOS

Application. (See “Connecting the WFED-300AC to Your iPad for the First Time” above.)

2. Unregister WFED-300AC WiFi Advisor Test Devices such that they can no longer be

selected for use within the WiFi Advisor iOS Application.

3. View information about each registered Test Device, including the Label Name, the Serial

Number, the Battery Level, the Power Off Delay, Firmware Version and other details.

4. Update the firmware on a registered Test Device

5. Check to see if a newer version of firmware is available in the cloud.

5.3 Updating Firmware for a Registered WFED-300AC

In the upper left of the Device Manager screen, the current version of firmware stored within the

iPad Application is shown under the label “Current Firmware”. This is the firmware version that will

be downloaded to a registered test device when the download firmware icon for a given test
device (on the right hand side of the screen) has been selected. The version of firmware currently
installed on a registered test device is viewable under the “Firmware” label in the Registered
Devices portion of the screen. Selecting the download firmware icon for a given test device will
replace the version of firmware on the test device with the version of firmware stored within the
iPad application as “Current Version”.

If there is a new version of firmware available in the Cloud, it will be shown in the upper right
portion of the Device Manager screen (“Version x.x.x Available”). Touching this text will present a
dialogue box asking the user if they would like to download the latest firmware version from the
cloud to the iPad application. If downloaded, the “Current Version” firmware in the upper left will
be replaced with the firmware version from the Cloud. From there, test devices can be upgraded
to the newly downloaded firmware.

5.4 Changing the Power Off Delay for a Registered WFED-300AC

The Power Off Delay values associated with each registered test device are shown within the
Registered Devices section of the Device Manager screen. These values define the amount of
idle time that must transpire before the test device will automatically power down. Touching the
current Power Off Delay value associated with a particular test device will launch a dialogue that
allows the setting to be changed. The available settings are:

OCT-2015 Technical Assistance: 1.844.GO VIAVI / 1.844.468.4284 19

Revision 2.0.5 [e-mail]

 Disable (no auto-power down functionality)
 5 mins
 10 mins
 15 mins
 30 mins
 1 hour

Touching a setting by name will change the setting for that test device. Touching outside of the
dialogue box will dismiss the dialogue without changing the current setting.

6. Using the SmartChannel Wizard

Selecting the SmartChannel Wizard icon from WiFi Advisor Home screen takes you to the
SmartChannel Wizard application. The SmartChannel Wizard helps users to quickly assess the
WiFi environment surrounding a specific BSSID of interest relative to user-definable thresholds
and common sense WiFi guidelines. The tool provides immediate feedback regarding WiFi
network health, and practical guidance for network optimization.

Once launched, the SmartChannel Wizard asks the user to select a Test Device from a list of
registered Test Devices and then pick the BSSID that they are interested in analyzing. The BSSID
is selected from a list on the right side of the screen. The 2.4GHz / 5GHz toggle switch
determines the band used to compile the list, and the list may be sorted by channel (123), by
name (ABC) or by signal strength (dBm).

Revision 2.0.5 [e-mail]

Once a BSSID has been selected, the SmartChannel Wizard will transition to the Summary
screen. The Summary Screen gathers information relative to the selected BSSID, its current

channel, the BSSID’s / associated stations within that channel and the BSSID’s / associated

stations in adjacent channels, then provides highly visible feedback via green “All Good” indicators
and warning signs. If warnings are presented, a corresponding set of recommendations are
provided to help the user improve the condition.
