INTRODUCTION
Wi-Fi around the home is increasingly important to consumers. Rapidly increasing
numbers of portable terminal devices, such as Smartphones, tablets, laptops or
“Internet of Things” gadgets, rely on wireless connections. Add gaming consoles,
set-top-boxes and even desktop PCs that are increasingly using wireless rather than
cables for Internet connectivity, and reliable Wi-Fi is now essential to reduce end user
frustration.
AirScout provides a rapid and largely automated means of surveying an entire home or
small business for effective Wi-Fi service. By surveying Wi-Fi coverage where it is wanted,
AirScout allows users to optimize the settings and placement of the access point to
maximize effectiveness in just a few minutes.
By using AirScout you can be assured that Wi-Fi service is reaching all the corners of the
premises when you leave the site. A test report can be produced recording the conditions
during the test and the performance of each location. Opportunities may additionally be
presented for the installer to offer solutions to correct “dead-spots” in the building, such as
repeaters, power-line extenders or wired access points.
AirScout works in parallel with your existing workflow as much as possible. Once the
test has been set up and started, you can continue with other preparatory tasks while
AirScout surveys the property automatically. You can then choose to check implementation
of channel and location choices for the access point before completing the installation.
Optionally, you may also repeat the test with the leave-behind access point hardware,
ensuring that its performance meets the needs of the customer as well.
AirScout not only presents its results in easy-to-interpret “heat-map” form but also allows
further exploration of the recorded results when needed to check for specific questions
such as “will 4k video streaming work in this room?”
Please read this manual and, if in doubt, also check www.greenleecommunications.com
for additional training material including links to videos showing setup and typical testing
scenarios.

2. Ensure Wi-Fi is enabled.
3. From the available networks select the SSID of the master.
4. Once the tablet or PC is connected, the AirScout SSID appears in the connected list.
Note: During testing the AirScout master will temporarily disable its Wi-Fi connection to
the tablet. If the tablet is in the presence of an alternate known Wi-Fi network or a carrier
Wi-Fi hot spot, the tablet may switch connections without your knowledge, preventing the
AirScout from re-establishing a connection. When this happens, the AirScout master will
indicate it is trying to re-establish a connection and the application will inform the user
that the connection has been lost. To avoid this situation, navigate to the Wi-Fi settings
menu, “forget” known networks, and disable auto connections to carrier Wi-Fi hot spots.
11
Pairing Clients to a Master
A master device can manage up to 30 connected clients. When pairing the AirScout
solution, all client devices may be paired to a master simultaneously. To ensure client
devices pair to the correct master, only pair one AirScout solution at a time if AirScout kits
are within radio range of each other. The client cannot discriminate between two masters
that are both in pairing mode. Prior to pairing, ensure that the client and master devices
are in close proximity and the battery is not low.
1. Ensure all devices are powered on and the right side power status LED is green.
2. To start the pairing process, press the pairing button on the master device; the left side
device status LED begins blinking green to indicate pairing mode is active.
3. While the master is in pairing mode, press the pairing button on one or more client
devices; their device status LEDs begin blinking green to indicate pairing mode is
active.
4. Once pairing is complete, each client device status LED turns solid green, indicating
that pairing was successful.
5. The master remains in pairing mode for two minutes.

3. Press the name field to bring up a keyboard and type in the desired name.
4. The master name will be retained.
15
Device Location Name
Each AirScout device measures and records the Wi-Fi characteristics at the location it is
placed. Naming the location where devices are placed provides a fast and simple way
to associate results with locations in the premises. The location names are stored with
the results allowing a customer, technician, or service representative to refer to named
locations within the premises. The best practice is to assign precise location names in
order to eliminate confusion when discussing results at a later time.
When Deploying Devices
Using the AirScout application, drag the master or client onto a floor plan. If the device
location is not set, the user will be prompted to enter a location. Client location names
are retained by the AirScout application while master location names are not retained and
must be entered each time a device is deployed.

AIRSCOUT APPLICATION MANAGEMENT
The AirScout application running on an Android or Apple device may be updated using
either the Google’s Play Store or Apple’s App Store. Updates provide the user with new
features and improvements. Refer to Apple and Google for installing and updating
applications.
AIRSCOUT CLOUD SERVICE MANAGEMENT
The AirScout solution works with Greenlee’s Cloud Service, providing an automated,
secure environment that links all of your AirScout test equipment results together,
centralizing captured data across your organization. AirScout results are automatically sent
to Greenlee’s Cloud Service or a coordinated independent cloud service when a Wi-Fi or
Cellular connection from the device to the Internet is available.
Prior to testing, contact Greenlee Communications at 800-642-2155 for technical
assistance establishing cloud services for your AirScout.
17
TESTING
AirScout provides a rapid and largely automated means of surveying an entire home or
small business for effective Wi-Fi service. AirScout works in parallel with your existing
workflow as much as possible. Once the test has been set up and started, you can
continue with other preparatory tasks while AirScout surveys the premises automatically.
During the testing phase AirScout optimizes settings and location of the customer’s
premises equipment, identifies and helps resolve issues affecting network performance
(such as signal quality, congestion and interference) and validates services (such as
streaming video, streaming audio, gaming and more).
Testing Step 1 – Entering Order Details and Customer Information
Prior to testing it is important to accurately enter the work order details and customer
information in order to associate results with the correct job order and customer for later
recall.
1. Enter the work order number, which is used by AirScout to recall results at a later time.
2. Enter the service level agreement (SLA) downstream, which is used by AirScout to
validate that Wi-Fi consumed bandwidth will not exceed the incoming bandwidth.
3. Enter the service level agreement (SLA) upstream, which can be used to validate that
Wi-Fi upstream bandwidth will not exceed the outgoing bandwidth.
4. Enter the access point type.
5. Enter the customer’s information, which is used by AirScout to associate the address
with the work order and may be used to recall results at a later time.
6.Press CONTINUE.
18
Testing with Customer Premises Equipment (CPE)
AirScout is capable of connecting to and testing using the customer’s premises equipment
(CPE) such as a Wi-Fi enabled gateway or access point. Testing using the CPE adds an
additional level of confidence to results. It is recommended to test using AirScout only or
using AirScout and the customer’s equipment.
1.Under Test Data, select the scan type: AirScout, Customer Gateway, or Both.
2. If either “Customer Gateway” or “Both” is selected, it is necessary to connect the
AirScout master to the CPE and provide the SSID and Password for the CPE. For
security reasons, AirScout will not record or save entered SSID or Passwords.
Note: Refer to section “Connecting AirScout to a Customer’s Premises Equipment
(CPE)” for directions.
3. After providing the SSID and Password, press CONTINUE.
19
4. If desired, press Edit to go back to the order details screen to edit the information for
the order.
Testing Step 2 – Floor Plans
AirScout provides the user a selection of simple floor plans for deploying devices in the
premises.
1. Select a floor type by pressing one of the floor types on the left side.
2.Press Rotate 90° to orient the floor as desired.
3.Press USE FLOOR PLAN to select.
20
4. Each time a floor is added, a default name is provided; if desired, the floor can be
renamed.
5. If multiple floors are required, press Add Floor to add an additional floor.
6. Floors may be deleted prior to testing by pressing the trash can icon.
7. A floor name may be changed by pressing the pen icon.
21
8. Press the stacked floor icon to toggle between single floor and isometric floor view.
9. If desired, a front door may be placed on the floor plan to help orient the view of the
heat map and the placement of ASC300s in the building.
10.If the floor plan needs to be updated, press Change Floor Plan to bring up a view that
allows the floor plan to be changed. Select the new shape for the floor plan, and press
USE FLOOR PLAN to return to the view with the updated shape.
Placing a Master
After a floor plan is created, the master and client devices need to be placed in the
premises. All available devices appear in the Parking Lot and display their status. Once the
master and one or more client devices are placed, testing can begin.
22
1. Identify the best location within the premises to place the customer’s premises
equipment, allowing access to power and the incoming wiring.
Note: Placing the customer’s premises equipment in the middle of the area to be
serviced by Wi-Fi is typically best. Keep the equipment and its antennas a short
distance away from walls and items that are largely metallic, e.g., televisions, ­­­
water-tanks or appliances; consider what may be on the other side of a wall.
Beware: Foil-backed wall boards inhibit wireless propagation, largely reflecting the
signal, while some solid wall materials absorb wireless signals very effectively. This is
why AirScout can be very effective at finding the optimum access point location.
2. Place the ASM300 in the identified location.
3. Using the AirScout application, drag the virtual master out of the Parking Lot and place
it on the floor plan in the same relative location.
4. The AirScout application requires a location name when placing the virtual master.
23
Placing Clients
1. Identify the rooms or locations outside the premises, such as a patio, where the
customer desires Wi-Fi services.
Note: This version of AirScout is not weatherproof so do not place outdoors during
inclement weather.
2. Place the ASC300 devices in these rooms or locations.
Note: When placing an ASC300, it is possible to lose radio contact as indicated by the
device status LED turning off. This is a normal occurrence, indicating that the location
is a radio dead zone and no Wi-Fi services can be obtained. The ASC300 can be left in
this location to record the dead zone in the results and help educate the customer. If
the ASC300 loses radio contact prior to moving the virtual client onto a floor, it will be
necessary to re-establish radio contact prior to moving the virtual client onto the floor
(only “connected” clients may be dragged onto the floor plan).
3. Using the AirScout application, drag the virtual clients out of the Parking Lot and place
them on the floor plan, matching their same relative location in the rooms.
4. Ensure the client location name matches the room where it is placed.
5. When placing the client devices, the AirScout application uses the existing location
name if present or requires a new location name.
6. Location names may be edited at any time prior to starting a test.
24
Testing Step 3 – Optimization
Testing can begin after placing the ASM300 and one or more ASC300 devices in the
premises and deploying all virtual devices onto the floor plan in the AirScout application.
1.Press Start Test to begin the optimization test phase.
2. The optimization phase concludes with recommendations for the optimal 2.4 GHz and
5 GHz channels and AP location. Optimizing the channel and location of the customer’s
premises equipment can result in significant performance improvements.
3. If within the timeout period a selection is not made, AirScout continues on to the next
phase of testing.
25
4. Changing the customer’s premises equipment to the optimal network channel can
minimize network congestion from nearby networks and improve performance.
5.Select YES to pause the AirScout application and allow the user time to change the
CPE channels.
Note: Refer to the customer’s premises equipment instructions for changing the
channel.
6. Moving the customer’s premises equipment to the optimal location and floor can
significantly improve network performance.
7.Select YES to pause the AirScout application and display the optimal location and floor,
allowing the user to determine if the CPE can be moved to the optimal location.
8. If the customer’s premises equipment can be moved to or near the optimal location,
relocate the ASM300 and the customer’s premises equipment to the new location on
the designated floor.
9. Move the virtual master to the new position on the designated floor and follow the
instructions for retesting.
26
Testing Step 4 – Multi-Dimensional Validation
After accepting or disregarding the optimizations, AirScout performs radio and Wi-Fi
application validation. AirScout validation results are displayed using multi-dimensional
heat maps, providing an intuitive, easy-to-understand method for visualizing results.
1. At test completion AirScout displays the signal strength in either isometric or single
floor plan view.
2. Pressing the multi-dimensional mode control allows the user to choose other result
dimensions.
27
3. Tap the Device Class drop down menu to select which 802.11 standard should be
visualized; 2.4 GHz (802.11n) or 5 GHz (802.11n/ac) options and multiple permutations
are available.
4. Press a client on the multi-dimensional heat map to display room performance
metrics.
28
Correcting Performance Issues
AirScout identifies multiple performance limitations related to signal quality, congestion
and interference, providing an opportunity to correct these issues.
Signal Quality
Radio dead zones and weak zones are displayed on the signal strength heat map. Dead
zones occur when a Wi-Fi enabled device is outside the radio range of the master or CPE.
Weak zones occur when signal strength is low or the signal-to-noise ratio is low.
1. Optimizing the CPE location can, under the right conditions, minimize dead and weak
zones.
2. Adding a second access point near the dead or weak zone is often an effective method
for eliminating dead or weak zones.
3. Adding a repeater between the working zone and the dead or weak zone is often an
effective method for eliminating dead or weak zones, but a repeater operating on the
same channel increases congestion, reducing maximum throughput.
Congestion
Congestion, defined by 802.11 as visible network traffic, is displayed on the client
room performance metrics menu. AirScout measures congestion due to other networks
operating on the same channel competing for radio resources.
1. Selecting the correct 2.4 GHz and 5 GHz CPE channel is the most effective solution for
minimizing congestion.
2. Select a 2.4 GHz and 5 GHz CPE channel that is not in use by any other network. It is
necessary to have complete AP visibility at every location within the premises where
network resources are used.
3. If all channels are in use, select the channel with the minimal number of clients or
lowest bandwidth utilization.
4. If all channels are heavily loaded, there may be no channel choice that can satisfy the
customer’s quality of experience expectations.
Interference
Interference is caused by devices emitting in the 2.4 GHz and 5 GHz 802.11 radio
spectrum and is a common problem. This includes 802.11 compliant devices on adjacent
channels, 802.11 compliant devices that are not cooperative, microwave ovens, cordless
phones, Bluetooth devices, wireless video cameras, wireless game controllers, Zigbee
devices, WiMAX, fluorescent lights, and more. Identifying possible common sources of
interference and eliminating them from the premises if possible is the best method of
minimizing interference.
1. Selecting the correct 2.4 GHz and 5 GHz CPE channel is an effective solution for
minimizing interference from other 802.11 compliant devices.
2. Select a 2.4 GHz and 5 GHz CPE channel with the minimal number of adjacent
channels.
29
Congestion and Interference from Other Networks
Congestion and interference are caused by other Wi-Fi networks operating on the same or
adjacent channels. Viewing the AP information that AirScout uses to assist in selecting the
optimal channel can be informative.
1. Using the AirScout application, press the selected virtual client or master to display
device status.
2. To visualize AP information, press Channel/AP Information.
The selected client or master will display all detected Access Points in its location.
For gateway tests, the gateway SSID is highlighted in black. AP results can be
displayed in graphic or detail formats.
30
3. Tap the Device Class drop down menu to select which type of access point to display
(2.4 GHz or 5 GHz). The subclasses (1x1, 2x2, and channel size) are irrelevant for this
view.

PROFESSIONAL MODE
For expert users, professional mode testing with AirScout provides a more flexible and
configurable test dashboard. In this mode, AirScout can conduct additional tests not
available during the basic mode operation. Professional mode is enabled by Greenlee
through the cloud.
In addition to the standard AirScout test, the new tests available in professional mode
include the following:
• Gateway testing with range extender support
• Internet speed testing to Greenlee’s cloud service
• Channel utilization measurement
33
Gateway CPE + Range Extender Testing
AirScout can connect to the Gateway CPE and range extenders to qualify the Wi-Fi
performance across the entire network of devices for this test. The range extender is used
as a way to expand the reach of the wireless LAN. It can be connected through coaxial
cables, power line circuitry, and Wi-Fi.
1.Under Test Data, select the Customer Gateway test checkbox with the “Provision
Devices to Use Gateway Extender(s)” box checked.
2. Connect the AirScout master to the gateway, making sure that all clients are
connected and in range of the master first, before they are physically placed. Each
client is connected to the master if both lights on the top cover are solid green.
3. After providing the SSID and Password, press CONTINUE.
34
4. On the floor plan page, the clients in the parking lot will indicate they have received
instructions from the master to join the gateway network by indicating a half-green/
half-gray diamond status. Once the clients have connected to the gateway or
range extender successfully, the diamond will turn solid green. Clients may change
connections during the course of placing them through the house as they re-evaluate
the signal strength conditions and prefer to join the gateway or range extender with
the strongest detected signal strength.
5. Physically place the clients and range extenders throughout the location, and
correspondingly place them on the floor plan in the application.
6. Once the clients indicate they have connected to the gateway or range extender on the
floor plan, press the Start Test button.
35
Broadband Speed Test
AirScout can test the broadband connection by running a speed test to the Greenlee cloud
service. This test provides an estimate of the available Internet bandwidth speed. Results
may vary depending on Internet traffic loading conditions. This test may be enabled by first
clicking on the gateway test checkbox and then selecting “Enable Broadband Speed Test”.
Channel Utilization Measurement
AirScout can determine the percentage of occupied air time for any channel in the 2.4 GHz
or 5 GHz bands. To run this test, select the “Perform Channel Utilization Test” checkbox,
and then select which band and dwell time is desired. Longer dwell times often provide
more useful measurements but can extend the test time.
36
LIVE MODE
Live Mode utilizes a single ASM300 to diagnose and optimize the wireless environment
dynamically. In addition, information about the wireless environment is collected by the
ASM300 and can be used to suggest an optimal configuration for 802.15.4 devices if this
feature is enabled. Live mode configurations are enabled by Greenlee through the cloud.
When starting live mode, wireless measurements such as existing network information
and channel utilization are immediately collected by the ASM300 from its current location.
After a brief period of time, channels supported will be populated with utilization and
interference stacked bars as well as WiFi network power and frequency occupancy
information.
37
The orange bar indicates Wi-Fi interference and the green bar indicates Wi-Fi utilization.
Under the utilization menu, there is an option to display or hide the bars for selectively
viewing elements.
Additionally, parabolas are shown that display the different Wi-Fi networks in that area
in terms of frequency occupancy/channel and strength, with the option of viewing either
2.4 GHz or 5 GHz bands.
To use live mode effectively, it can help to move the master to areas where Wi-Fi
performance is a concern. After approximately 20 seconds, data will be collected for the
area, so it is recommended to keep the ASM300 stationary during that period. Paying
attention to AP signal strength in this location may help the user discern if there is a signal
problem in the area. Tapping on a network of interest on the right of the display will label
the network selected, allowing easier monitoring of its signal strength. This information is
also available in tabular form in the Data Details view.
38
802.15.4 Optimization
802.15.4 Optimization is an optional part of the live mode feature set, enabled by Greenlee
through the cloud.
Data gathered in live mode is continuously processed to optimize the 802.15.4
environment.
Tapping on the 802.15.4 switch will present a scrollable dropdown that allows selection of
a network to improve 802.11 coexistence with 802.15.4.
39
Once a network is selected, 802.15.4 recommended channels are displayed on the right
that correlate with the small parabolas on the bottom of the graph. Parabolas marked
in green are the current best suggested 802.15.4 channels, with red being the worst.
The resulting channel plot can be used to tune 802.15.4 networks by setting frequency
hopping masks that correspond to these best channels while avoiding interference or
congestion from other channels.
40
QOE – QUALITY OF EXPERIENCE
The AirScout quality of experience (QoE) score is a measure of the customer’s
experiences with services such as video streaming, audio streaming, gaming, web
browsing, etc., delivered over their Wi-Fi network. To determine QoE, AirScout analyzes
multiple environmental parameters related to signal quality, congestion, interference
and bandwidth. The QoE score provides a quick and intuitive assessment of customer
expectations for delivered services with respect to signal quality, congestion, and
interference conditions.
ASC – Quality of Experience Score
Each location QoE score is based upon a function of the signal quality, interference,
congestion, and, if measured, bandwidth. Apart from bandwidth, each of these parameters
are functions of more than one measured variable. This method of distilling a group
of complex measurements into simple “scores” makes the AirScout system far easier
to understand. The ASC QoE score provides an assessment that can be compared to
customer expectations for delivered services in each location within the premises,
providing quick identification of QoE degradation in one or more locations. Once QoE
degradation is identified, the customer can be notified and preventative action can be
determined, such as moving the gateway or installing secondary access points. The whole
building QoE score is the average of the scores for all tested locations.
QoE Score = Excellent (5)
A QoE Score of 5 is obtained when:
• Signal quality degradation is zero, permitting operation at maximum 802.11

SERVICE LEVEL AGREEMENT ANALYSIS
AirScout can evaluate the bandwidth coming into the premises, defined by the service
level agreement (SLA) and the customer’s Wi-Fi bandwidth utilization. If AirScout
determines the SLA cannot support the customer’s bandwidth requirements, AirScout
notifies that a bandwidth limitation exists. The customer can be informed of the bandwidth
limitation and provided with an option to increase the SLA bandwidth.
