Nemo Walker Air
Indoor Benchmarking On the GoNemo Walker Air is a compact multi-technology solution for indoor measuring
and benchmarking. Nemo Walker Air, an Android-based multi-technology
solution, performs extensive synchronized measurements and synchronized script
events. One tablet acts as a master, conducting multi-measurements by sending
commands to up to seven test terminals via Bluetooth® connection. Nemo Walker
Air features POLQA and PESQ voice quality testing, PEVQ-S video quality testing,
and HTML testing with real web browser capability. It uses the internal GPS
receiver of a smartphone to log and display geographical coordinates. An optional
backpack offers a compact carrying solution for the whole system.

Nemo Walker Air offers a solution for measuring the air interface of 5G NR (with
Qualcomm X50/X55 and Samsung Shannon chipset based devices), LTE/LTE cat 12, WiFi
Dropbox testing, email testing, SMS and MMS messaging, and ping.
Nemo Walker Air’s measurement data gives you a complete and detailed picture of the
radio interface and the quality of the tested applications. The detailed and comprehensive
radio interface data recorded with Nemo Walker Air is optimal for network planning, roll-
out, tuning, verification, optimization, and maintenance. The application performance
metrics are vital in mobile service benchmarking and QoS/QoE evaluation. Continuous
recording of radio interface metrics ensures that the reasons for less than satisfactory
service quality can always be found.
Log files can be uploaded to FTP/HTTP server from master unit or collected manually from
slave units. Nemo Walker Air’s full and proven compatibility with third-party tools enables
also post-processing with any other tool supporting the Nemo file format.
5G NR Scanner MeasurementsNemo Walker Air supports 5G NR scanner measurements using PCTEL IBflex and PCTEL
HBflex scanner devices. The collected metrics are NR-ARFCN, physical cell identity, and
beam index. In addition, PCTEL HBflex supports millimeter wave frequencies up to 40
GHz.

Configurations
The Nemo Walker Air package includes one master tablet and 1 to 7 slave units, all
including the Nemo Walker Air software. Slave units can be chosen from a selection of
the latest smartphone models. The optional Nemo Walker Air backpack includes high-
quality USB batteries, and can be used as a standalone system without an external
power source. The runtime of the complete system is up to 10 hours, making it possible
to use Nemo Walker Air for a complete working day without having to re-charge it. The
backpack also includes one 12/220/110V charging cable for the whole system.

Scanning option
Nemo Walker Air supports PCTEL IBflex, and PCTEL HBflex scanners. The portable
battery-operated scanners make it possible to combine scanning and indoor
measurements with Nemo Walker Air. When using PCTEL IBflex/PCTEL HBflex scanners
for measurements in conjunction with Nemo Walker Air, it is possible to:
• Increase your indoor / walk test efficiency
• Perform multi-frequency scans on all technologies and bands
• Measure single channel coverage
• Measure best server plots compared to the serving cell used by the test terminal
• Improve co-channel and adjacent channel interference detection
• Decode BSIC information from the serving cell, neighbors and other channels
• Utilize Missing Neighbors detection/Neighbor list planning and Planning handover zones
• Detect interference from other sources out-of-band
• Improve detection of Pilot Pollution (No dominance)

Data Views and User InterfaceIndoor measurements
Nemo Walker Air provides indoor map (floorplan) support with an easy-to-use interface
that includes zoom and pan tools. Import digital images into Nemo Walker Air master
and convert them into map files (.tab), or take a picture of a floor plan with the phone’s
camera to be used as indoor map. Nemo Walker Air also supports the iBwave map
format. You can set the scale of the map based on a known distance on the map and
set the geodetic coordinates of the map based on two known coordinate positions.
Nemo Walker Air geocodes indoor floorplans on top of the Google Maps. You can also
modify existing floorplans that are not geocoded directly from the Nemo Walker Air
interface. The measurement route can be drawn on the map with markers.
In Nemo Walker Air, there are two ways to track the location of the Nemo Walker Air unit
indoors and place waypoints, i.e. markers, automatically. With the automated location
mapping feature, a tracking module is used to position the Nemo Walker Air unit and the
measurement route is is automatically displayed on the device´s screen. The automatic
indoor positioning feature enables placing markers automatically by utilizing camera
and other sensors on the terminal to get the speed and position indoors when GPS is
not available. The faults in the network can be pinpointed accurately, ensuring reliable
analysis of the results and allowing you to concentrate on the actual troubleshooting
instead of on adding markers on the map while walking.
When importing an indoor map into Nemo Walker Air, you are also able to create
and use a route plan that you want to follow.Turn logging on, walk according to the
route plan and add a marker when you reach the next waypoint on the map. After the
measurement Nemo Walker Air provides a measurement and marker file that can be
used in post-processing.

Nemo Walker Air performs Distributed Antenna Systems (DAS) testing. Use iBwave
indoor plans or BTS files to see indoor small cell antennas and transmitters displayed
on the indoor map. During a walking test a user-defined visual notification on the map
indicates whether the current DAS antenna is transmitting or not.
Nemo Walker Air exchanges project information directly between iBwave Planner
and Nemo Walker Air. iBwave Planner and Nemo Walker Air both run on the same
device using the IBWC file as a common medium. This allows you to create a floor plan
in iBwave Planner, switch to Nemo Walker Air for the measurements and switch back to
iBwave Planner to create a preliminary design.
All network parameters supported by the terminal’s mobile trace interface, including
signaling messages, are logged and made available for playback with Nemo Outdoor
and for easy analysis and reporting with Keysight’s Nemo post-processing tools. You
can select a custom set of metrics measured by the slave units to be monitored in real
time with the master. Metrics are also visible on the slave screens in real time.
View application testing and RF parameter displays simultaneously. Application QoS/
QoE statistics are displayed in real time for all of the supported applications.
