Phone number defines the recipient phone number. Call duration defines the duration (in seconds) of the call, unless used with Call End Condition (see below). Attempt timeout defines the maximum duration (in seconds) of the call attempt. Call end condition defines an end condition for the call based on the active system (Until system is GSM/UMTS/LTE), i.e. the call is terminated when a specific system becomes active.  If a call end condition is defined, call duration countdown will begin only after the call end condition terminates the call. Thus it is recommended that also call duration is defined. This is to ensure that the events after the handover are logged as well. 

Call end conditions are supported with voice calls only.

Voice quality mode (Off/Uplink+downlink) defines the voice quality mode. The options are off and uplink+downlink. Sample file defines the voice sample file used in the voice quality testing. There are two types of samples: wideband and narrowband. If the sample filename has a “wb” postfix, the sample is wideband. Otherwise it is narrowband.

POLQA measurements can be done in Super Wideband (SWB) or in Narrowband (NB) mode. The mode is selected automatically based on the sample, that is, if a wb sample is selected, SWB POLQA measurement mode will be used. Respectively, if NB sample file is selected, NB POLQA measurement mode will be used. 

Note that PESQ measurements can only be performed in narrow band mode

MOS threshold can be used to limit the number of samples saved to the measurement file. For example, only samples with a MOS score below 3 are saved. Uplink volume sets the uplink volume level. Please note that in most cases the default value is recommended.

Scripted Call Answer  Note that Script call answer command must be situated in the script between the Packet Session commands PacketActivate and PacketDeactivate.

Timeout defines the time in seconds for how long Nemo Walker Air waits before automatically answering incoming call.

Scripted Iperf TCP/UDP  Note that the Iperf TCP/Iperf UDP command must be situated in the script between the Packet Session commands PacketActivate and PacketDeactivate. To add a script command for using Iperf TCP or Iperf UDP, select Add | Iperf TCP transfer/Iperf UDP transfer in the Script Editor main view.

First define whether you are sending (Uplink) or receiving (Downlink) data or both. Server is the IP address used in Nemo Server. Server port refers to the port used by Nemo Server. For TCP and UDP protocols, the default port is 5001. Duration defines the length of the data transfer in seconds. Data size defines the length of the total data transfer in kilobytes; that is, the transfer finishes when the defined amount of data has been transferred. TCP window (KB) defines the size of the receive window during TCP/IP transmission. If it is too small, it can decrease the maximum data throughput, and if it is too high it can increase the retransmission round-trip time (RTT). To be able to avoid decrease of data throughput, the window size should be at least the maximum throughput multiplied by RTT. For example, with HSDPA with category 8 the maximum throughput is about 7.3 Mbit/s and RTT is about 100 ms. To avoid reduction of the throughput the TCP window size should be set at least to 7.3 Mbit/s * 0.1 s = 730 kbit = 91.25 kB. UDP datagram size defines the size of the UDP packet in bytes. It should be smaller than the maximum packet size of the lower layers to be able to avoid packet fragmentation in the lower layers. Packet fragmentation has a huge negative impact to the achieved data throughput and it should be avoided. On the other hand if too small UDP packet size is used the portion of the UDP and IP header increases which decreases the amount of transmitted user data with the result of smaller data throughput. Normally good maximum value for UDP datagram is a little bit less than maximum Ethernet packet size which is 1,500 bytes. A good default value for the UDP datagram size is 1,460 bytes. UDP bandwidth (kbps) defines how much data is attempted to be transmitted. Since UDP does not guarantee successful data transmission, it is not limited by maximum throughput of the lower layers. If higher bandwidth is used, the packet error rate (PER) increases. For example, if lower layers are capable of transmitting 100kbit/s and UDP bandwidth is configured to 400kbit/s, there should be a 75% packet error rate (only every fourth packet has been able to transmit successfully). Naturally UDP bandwidth should not be configured too small since it limits the maximum throughput that is not normally desired.

Scripted Facebook Testing

Test type defines whether you want to get friend list, get wall feed, post status update or post photo. Attempt timeout defines the maximum duration (in seconds) of the call attempt.

Wait To add a wait period in the script, click the Add button and select Wait from the popup menu. The Wait Properties view opens.

Wait (s) defines the wait period in seconds. But at most value is the maximum wait time in seconds if the defined notification does not appear. Wait Condition defines a wait condition based on the active system (When system is GSM/When system is UMTS), i.e. the wait period continues until a specific system becomes active. Note: If both Wait Condition and Wait (s) are defined, the Wait (s) countdown will begin only after the Wait Condition is met. Wait from enables you to select one of the following options: Current time enables you to define a pause between items in the script. For example, you can set a 10 second pause after a voice call is finished and before the next call starts. The options Call Attempt, Video Call Attempt, and Context Activation Attempt enable you to define a wait period after the selected event notification. For example, you can make the script pause for 60 seconds after a call attempt event. This will prevent the script from continuing before the call attempt has completed.  If a Wait Condition is defined, it is recommended that also a wait period (Wait) be defined. This is to ensure that logging starts only after handover has successfully occurred.

Nested Script A nested script is a script inside a script. Nested scripts enable you to run automated measurements combining multiple scripts. You can use nested scripts to run several scripts one after another. You can use nested scripts to e.g. make 10 voice calls and after that 10 data transfers and repeat that for 1000 times, without having to define 20 transactions in the script. Instead, create a script that makes one voice call with a repeat of 10, and another script with 1 data transfer with repeat of 10, and put them both as nested scripts in the same parent script. To add a script command for a nested script, select Add | Nested script in the Script Editor main view.  Please note that nested scripts can be only added in scripts that do not have other transactions than other nested scripts.

Script defines the script file that will be nested. Tap the field and select a script from the list. Run condition defines how long the script will be run. If you select Until finished, the script will be run until it is finished. If you select Max time, you will need to define in minutes the maximum duration of the script. Repeats defines how many times the script is repeated.

VOICE QUALITY TESTING 

Please note that voice quality testing requires the voice quality license option.

Nemo Walker Air supports voice quality measurements based on POLQA (ITU-T Rec. P.863) and PESQ (ITU-T P.862.1) algorithms both in uplink and downlink directions. SWB (Super Wideband) and NB (Narrowband) POLQA measurement modes are supported. Results are reported on MOS (Mean Opinion Score) scale. The POLQA MOS scores are calculated in real-time in Nemo Walker Air and displayed on the screen. The PESQ MOS scores are calculated in the post-processing with Nemo File Manager based on the audio samples that are saved in the measurement files.

To set up voice quality testing between Slave units, please follow the steps below. 

Please note that the last steps regarding Calling terminal and Answering terminal concern Slaves, all other steps are done on Master.

Timeout defines in seconds how long Nemo Walker Air waits before automatically answering an incoming call. Max duration (seconds) defines the maximum duration of the call (in seconds) before Nemo Walker Air ends the call. With the default value 0 Nemo Walker Air does not restrict the duration of the call but waits for the counterparty to end the call. Voice quality mode (Off/Uplink+downlink) defines the voice quality mode. The options are off and uplink+downlink. Sample file enables selecting a sample file to be played during the call. MOS Threshold and Uplink volume have varying default values depending on the used device.

2. Load script into answering Slave. Go to Master control page, and select a Slave by pressing long on it. Tap Load script, and select the previously created script file.

Go to Menu | Settings | Settings | Voice quality. Define the voice quality mode and select the sample file. Voice quality testing can also be performed using scripts. To turn voice quality testing off, select Off in the Voice quality mode field.

POLQA NB/SWB Mode Selection POLQA measurements can be performed in Super Wideband (SWB) or in Narrowband (NB) mode. The mode is selected automatically based on the sample used, that is, if a wb sample is selected, SWB POLQA measurement mode will be used. Respectively, if NB sample file is selected, NB POLQA measurement mode will be used.  Note that SWB POLQA measurement mode should be always used with voice calls where WB AMR codecs are used. WB AMR is used only in mobile-to-mobile voice calls where in both ends the mobile is WB AMR capable and the WB AMR codec is enabled in the network. Also AMR WB codec must be activated from the AMR codecs selection in forcing menu.

Voice Quality Testing in Uplink+Downlink Mode If you select the Uplink+downlink voice quality mode, you will need two terminals or one terminal and a Nemo Server. Make sure you have the same settings (mode and sample) in both ends. Also activate the auto-answer mode in the terminals (Menu – Settings – Settings – General – Answer incoming calls). Make a voice call from one unit to the other. The units will be sending and receiving the sample in turns until the voice call ends.

PESQ voice quality testing PESQ score cannot be calculated in the phone in real time. Instead, it is calculated in the post processing in Nemo File Manager. In the File Manager the saved audio samples are processed from the .nbl file. The .nmf file will thus contain both PESQ and POLQA scores, which are calculated for every audio sample, embedded in the .nbl file. When the PESQ dongle is installed and a POLQA measurement file with embedded audio samples is processed, also the PESQ score is calculated.  Note that copy protection dongle with PESQ option is required in the Nemo File Manager PC to perform the PESQ calculation.  Note that Voice Quality settings in the File Manager do not affect whether the audio samples are saved or not. Menu | Settings | Voice quality | MOS threshold. MOS threshold defines the limit for saved audio samples. All audio samples with POLQA MOS score that is below the defined limit will be saved with the logfile. This makes it possible to playback the actual audio samples in the post-processing.  Note that the threshold must be set to 5 (all samples are saved) when measuring also PESQ. This is because PESQ calculation is done in the Nemo File Manager in post-processing.

FORCING FEATURES Nemo Walker Air supports band locking, system locking, preferred channel locking (UMTS only), and AMR codec activation. Support for the locks is terminal-specific so please refer to the Nemo Walker Air data sheets to see which locks are supported by your test device.

IP CAPTURE IP capture can be found on Walker Air Slaves. Application level data can be captured with Nemo Walker Air. The data is collected in a separate log file in .pcap format. Pcap files can be processed with Nemo Outdoor, Nemo Analyze, or Wireshark. By default, full IP capture, including IP and all above layers are captured. Pcap log files can be very large if no filtering is applied. Therefore, it is practical in most cases to apply filtering to capture only the protocol layers of interest. Capture filter rules are read from a text file. Rules must be defined in the standard Wireshark filter format.

For logging view go to Settings | Settings | Logging IP capture option activates/deactivates IP packet capturing. IP capture filter option defines whether captured packets are filtered. IP capture filter rules allows you to define IP capture filter rules. The rules must be placed in the root directory (/Nemo/Handy/) as a text file with .txt ending. IP capture is started whenever you start logging with Nemo Walker Air and stopped when logging is stopped. You can upload IP capture files to a server by selecting the Upload packet capture files option in the Log file name dialog that appears when you stop logging.

INDOOR MEASUREMENTS You can view indoor maps in Nemo Walker Air and plot the measurement route on the map with markers.

Importing Maps and Defining Map Settings If this is the first time you are performing indoor measurements with Nemo Walker Air, you will need to import an indoor map (i.e. a floorplan) to Nemo Walker Air as an image file. The supported formats are .jpg, .jpeg, .gif, and .png. Transfer the image file (e.g. Floorplan.jpg) to the sdcard/Nemo/Walker Air/Maps folder on the memory card of your Nemo Walker Air terminal by using e.g. a Bluetooth connection, a cable connection, or a memory card reader. You can also take a photo, for example, of an emergency exit plan and use that as an indoor map. In Nemo Walker Air, select Menu | Settings | Settings | Indoor | Floorplans and tap Add to choose or import a map or take a picture to be used as floorplan. If this is the first time you are performing indoor measurements, Nemo Walker Air will generate a MapInfo file (.tab) based on the image file. Next time you make measurements and use the same map, Nemo Walker Air will use the .tab file automatically. A MapInfo map always consists of two files: a MapInfo .tab file and an image file. The resulting floorplan (.tab) will be listed on the Floorplans page. You can have several floorplans loaded at the same time. For example, you can have a floorplan from each of the floors of a building. Select a file and tap the Up and Down buttons to rearrange to order of the floors on the map.

Route plan defines the route plan file (.rpf) displayed on the indoor map. File type defines whether the floorplan dimensions are defined in meters (width/height) or in geodetic coordinates. Width defines the floorplan width in meters. Nemo Walker Air enters a default value (number of pixels in the image divided by ten) for the field, but you should enter the correct value. Height defines the floorplan height in meters. Nemo Walker Air enters a default value (number of pixels in the image divided by ten) for the field, but you should enter the correct value. Longitude defines the geodetic coordinates of the left and right sides of the map. Enter coordinates in decimal degrees (e.g. 25.4714). Latitude defines the geodetic coordinates of the top and bottom sides of the map. Enter coordinates in decimal degrees (e.g. 25.4714). Next, define indoor settings from the Indoor Map settings view (see Indoor Map). After defining indoor settings, you are ready to begin measurements.

TIPS AND HINTS This section gives some tips and hints for using Nemo Walker Air.

FILE LOCATIONS The various files associated with Nemo Walker Air have specific file locations. When adding files to Nemo Walker Air, you should only use these specified folder locations for the files. Measurement data files are saved to sdcard/Nemo/Handy/Results folder on the memory card of your Nemo Walker Air terminal by using e.g. a Bluetooth connection, a cable connection, or a memory card reader. The following are the file locations where Nemo Walker Air related files should be saved. Measurement data (.nbl)  sdcard/Nemo/Handy/Results Display configurations (.xml)  Display configurations are installed to the "/sdcard/Nemo/Handy/Config" directory.

USING THE GPS RECEIVER If you move too far away from the external Bluetooth GPS receiver or the receiver battery goes flat, the GPS state in the Nemo Walker Air GPS view switches to ‘Not connected’. In such a case, you do not need to restart Nemo Walker Air, just check that you have chosen the correct GPS port in settings. If you want to change to another Bluetooth GPS receiver, you need to delete the pairing between the existing GPS receiver and Nemo Walker Air first.
