will need to restart the computer.


8.4 Uninstallation

♦ Note that for Windows® XP and Windows® 7, the uninstallation must be run under Administrator account or

other user account with administrative privileges.

Nemo Outdoor application must be uninstalled via Add or Remove Programs. NOTE! With Nemo Outdoor versions

5.80- 6.21 the copy protection key must be attached to USB port during the uninstallation. With Nemo Outdoor 6.3.x

onwards copy protection module is not needed during uninstallation. When the Nemo Outdoor software

uninstallation is complete, you will need to restart the computer.

8.5 HASP Dongle Runtime Drivers

♦ Note that the Nemo Outdoor setup includes the required HASP dongle runtime driver compatible with the

application. The driver should not be updated, for example, with Windows update or using a separate driver

setup downloaded from the internet. It is recommended not to install any other applications using the HASP

dongle runtime driver as different versions can conflict. In case the HASP dongle runtime driver is updated and

it conflicts with Nemo Outdoor, an uninstallation of the current driver should be done via “Uninstall or change

program”. Locate the application called “Sentinel HASP Run- Time” and uninstall it. Re-install Nemo Outdoor

application.

9 Limitations and Issues with Windows 7 Operating System

The following limitations with Windows 7 operating system have been noticed and verified by Anite Finland or

informed by the vendors:

• ZTE MF820T modem with Windows 7 OS. Device is conflicting with the Sentinel HASP key driver used with

Nemo Outdoor application. After ZTE modem is installed, Sentinel HASP key cannot be detected by Nemo

Outdoor. A workaround is to change the auto tuning settings to normal immediately after the ZTE modem is

installed. Please see section 13.2.3 for further details on how to change the auto tuning mode

• Devices not supporting Windows 7 operating system:

o PCTEL LX tri- band scanning receiver

• Other limitations:

o IP packet capturing via Nemo Outdoor does not work with Windows 7 64-bit version. Packet

capturing must be done using third party application

o Debug logging needs administrative privileges if User Account Control Settings (UAC) is enabled. It’s

recommended to change UAC settings to “Never notify”. This can be done via User Account Control

Settings

o If UAC is set to always notify it might cause issues with data testing. PS connection can be

established but data transfer cannot be done. It’s recommended to change UAC settings to “Never

notify”. This can be done via User Account Control Settings


Figure 2. UAC settings.

10 File Format Changes

Nemo Outdoor version 6.4.1.8 supports Nemo file format version 2.15. Nemo Analyze version 6.30.1 is compatible

with Nemo file format version 2.14.

11 Known Issues

11.1 General & User Interface

• Note that if there is a system that measures acceleration in the laptop and which causes the hard disk to stop

when jolted, it should be turned off. Otherwise there may be breaks in the measurement files. With voice

quality testing this can be seen with missing MOS scores, and with other test devices with gaps in the

measurement results.

Figure 3. Lenovo active protection system properties.


• Download stops responding. Applies to Windows XP, Windows Vista and Windows 7 operating systems. When

you try to download a file, the download stops responding and then times out. The problem occurs when you use

a USB modem that has a data transfer speed that is faster than or equal to 240 kilobits per second (Kbps). The

problem occurs because of a limitation in the current USB modem driver (Usbser.sys). The hotfix download is

available from http://support.microsoft.com/kb/925681

Please select “View and request hot fix downloads” and follow the instructions to download the appropriate file.

Files can be found also from the DVD supplied by Anite (Nemo Outdoor 6.0\Setup\Microsoft hot fix). Please note

that for each operating system there is a separate file available:

o Windows 7, Windows6.1-KB925681-x86.msu

o Windows Vista, Windows6.0-KB925681-x86.msu

o Windows XP, WindowsXP-KB925681-x86-ENU.exe

• It is highly recommended not to use the User Parameters functionality during multi device testing as the decoding

of L3/ RRC messages will cause a high CPU load. If performance problems are found, it is recommended to

remove all user parameters from the user interface.

• If the message “Server Busy” is displayed on the screen, it is recommended that the packetmon.exe be killed

using the task manager. Packetmon.exe is used by the Microsoft Network Monitor. Microsoft Network Monitor is

needed only with the video streaming quality or IP packet capturing functionalities. If IP packet capturing or video

streaming quality measurements are not required it’s recommended to not install Microsoft Network Monitor.

11.2 UEs

11.2.1 Altair-based UEs

• Harris MBC-100: UE frequently has gaps in the trace messages during idle mode even power saving is

disabled. Issue is seen with the firmware ALT3100_04_00_02_00_32_TF. Issue has been reported to chipset

vendor

• NSN USB-lte 7210:

o NSN connection manager application must be closed when the UE is used with Nemo Outdoor. When

the UE is connected to a USB port, the connection manager is automatically launched. This can be

avoided by changing the file name. Browse to "C:\Program Files\NSN LTE Connection Manager” and

rename the “nsnltecm.exe” to “nsnltecm.exe_"

o Power saving for UE should be disabled using the ADCC application provided by Altair with UEs having

firmware version ALT3100_04_00_02_00_23_TF. UEs with the firmware ALT3100_04_00_02_00_32_TF

or later power saving can be disabled by sending the following AT command to UE:

AT%SETCFG="PW_IDLE","NONE"

o This can be done e.g. using Nemo Outdoor application via measurement properties of the UE.

o The modem gets extremely hot during measurements. When the UE is overheated, trace messages are

not reported but the data transfer continues normally.

o UE frequently has gaps in the trace messages that occur about every 10s and last for 800ms.


o To avoid performance issues with the modem, the following modification is recommended. By this

modification the Altair LogCreator standalone functionality is disabled. Browse to folder C:\Program

Files\NSN LTE Connection Manager\Tools\ Internals\LogCreator\ and open file RunLogCreator.bat with

Notepad. Modify the following string:

Original:

LogCreator.exe -SA -FN:"50" -E -Y4:"LOG_SOCK_IF" -D4:".\LoggerDB\LTELogDB.txt" -

D1:".\LoggerDB\PhyFWLogDB.txt" -Q:"50000"

Modified:

LogCreator.exe -E -Y4:"LOG_SOCK_IF" -D4:".\LoggerDB\LTELogDB.txt" -

D1:".\LoggerDB\PhyFWLogDB.txt" -Q:"50000"

11.2.2 Cassidian Handsets

• MER value is not reported by the terminal

• The terminal does not answer all incoming calls when call modes are semi duplex or duplex. Auto-answer can

be enabled in the following ways with THR880i and THR880.

o THR880i:

• Plug in a headset (Nokia Headset Type HDC-9)

• Settings / Enhancement Settings / Headset / Automatic Answer --> On

• Settings / Profiles / Headset / Personalize / Incoming Call Alert: this must not be "Off".

• Settings / Profiles / Headset / Activate

• Reboot the phone.

o THR880i: Before the terminal can be used with Nemo Outdoor, the field test mode of the terminal must

be activated by the Cassidian TETRA Prorgramming Tool. Tool is available only from Cassidian.

o For THR880 the procedure is identical, except that there is a slightly different menu structure for the

steps. Instead of Settings | Profiles | Headset, the correct path is Profiles | Headset.

11.2.3 Datang/Leadcore Handsets

Please see the Nemo Outdoor 6.31 Release Notes for the known issues found with the Datang DTM8129 and Leadcore

LC 8130E handsets.

11.2.4 Motorola Handsets

Please see the Nemo Outdoor 6.31 Release Notes for the known issues found with the Motorola V9 handsets.

• Motorola iDEN i886:

o Handovers are not reported during packet session

o CREL has incorrect old cell information (same as the new cell)

o CELLMEAS writes the "Number of cells" to n-1, even though there are n cells reported. This causes

Outdoor not to show results for one reported cell.


11.2.5 Nokia Handsets

• Nokia general issues:

o Nokia connectivity cable driver with the Windows Vista operating system has been found to cause a

problem when establishing PDP context activation and also instabilities with test terminals.

o Usage of WCDMA RLC messages will cause phone instability during high-speed PS data activity. This is a

performance restriction. By default, RLC messages are not enabled with Nemo Outdoor.

o Terminals do not update the L1 counters (first 2 octets) in uplink SACCH PDUs that are reported to Nemo

Outdoor. These two octets always have value 0x00 0x00. This problem has been reported to Nokia.

• Nokia 500:

o Video calls are not supported by the handset

o Charging problem: During measurements after battery is fully charged, charging stops and does not start

again. In this case it is possible that the battery runs out during a long test.

o USSD testing is not supported

o With voice quality tests handset must be charged with an AC/DC 110/ 220V charger

• Nokia E7-00:




o Concatenated SMS testing is not supported. Max. 160 charaters are supported.

o Windows XP fix KB943198 (http://support.microsoft.com/kb/943198) is needed when using HSDPA

category 6 or higher data transfer speeds.



o When the UE is locked to a WCDMA carrier, it only updates the intra-freq cell list and configured triggers

from SIB11 / SIB12 messages, and ignores the "measurement control" RRC messages updating intra-freq

measurement configuration.

o During measurements, the battery might run out because the terminal can be charged only via a USB

charger. It is highly recommended to use separate charger during measurement.

o During voice quality testing if separate charger cable is disconnected from terminal it can decrease MOS

score. It is recommend to unplug the charger after measurement is stopped.

o To further increase stability, it is recommended to do the following from the UI:

• Set Theme effects to OFF

• Set Animated background to OFF

• Set Call image to none

• Set Screen saver to none

• Delete additional home screens


• Set widgets to offline mode

• Set WLAN scanning to OFF

• Set sensors to OFF

• Nokia C7-00:


o With multiRAB testing UE is crashing due to limited power.



o Concatenated SMS testing is not supported. Max. 160 charaters are supported.

11.2.7.7 Samsung Handsets

• Samsung Galaxy Ace:

o Video calls are not supported

o No indication of incoming SMS message

o MMS testing is not supported

o Multi RAB works only if PS connection is established after voice call connection

o Device is shutting down when system lock is used

o PDP context activations and deactivations with multiple Samsung/Qualcomm terminals occasionally

cause instability problems with dial-up connections. Avoiding these commands when using script files is

recommended.

o International numbers starting with + do not work with Samsung terminals. It is advised to use 00 instead

of +.

• Samsung Omnia 7/ Focus/ Galaxy Ace:



o Multi RAB works only if PS connection is established before voice call connection

o Device is rebooting when system lock is used


o PDP context activations and deactivations with multiple Samsung/Qualcomm terminals occasionally

cause instability problems with dial-up connections. Avoiding these commands when using script files is

recommended.

o International numbers starting with + do not work with Samsung terminals. It is advised to use 00 instead

of +.

• Samsung SGH-A847:

o USB mode must be set to "Samsung PC Studio" to have the ports available. (Can be set permanently from

Menu -> Settings -> Connectivity -> Select USB Mode -> Samsung PC Studio)

11.2.7.8 Sierra Wireless Modems

• Sierra Wireless 312U/ 319U:

o Occasionally the network adapter interface (NDIS) disappears and device cannot perform PS data

connection. Workaround is to use the modem with microSD card or by disabling microSD card from the

device. By default Sierra Wireless modems do not include microSD cards. The microSD can be

permanently disabled with either AT commands or via a command line utility. The command line utility

ItmTk.exe can be downloaded from the Nemo User Club under “Drivers for Test Devices” folder. For AT

commands use e.g. Hyperterminal.

AT!ENTERCND=”A710”

AT!CUSTOM=”USBMSENABLE”,x 0=disable 1=enable

o Device is unstable with Win 7 operating system. Issue is seen especially with Lenovo computers. Issue is

seen with failed PDP context activations and it also causes Windows file corruption on all processes

under Windows 7 operating system. Measurement log file(s) might be empty or incomplete missing

footer information. This issue has been reported to vendor. It is recommended to use Windows XP SP3

operating system. Multi measurements with 319U are not supported at the moment with Lenovo

computers.

o No indication of incoming MMS message

• Sierra Wireless 312U/320U:

o If Lenovo W510 or other computer with USB 3.0 ports is used with Sierra Wireless USB modems, the

computer crashes immediately after the second USB modem is connected to the USB 3.0 port. Problem is

experienced with all 3xx- series USB modems provided by Sierra Wireless.

o The Watcher application must normally be running simultaneously with Nemo Outdoor in the

background if default settings of the application are used. However it is recommended to change the

default settings of the Watcher application to avoid any issues during measurements. If the user wants to

close the Watcher application but still wants to be able to conduct measurements with Nemo Outdoor,

the following settings from the Watcher application must be selected. NOTE! The option names seen in

the Watcher application depend on the application version. If multiple modems are used

simultaneously on the same computer, these settings must always be changed!


Figure 5. Watcher application.

• Watcher autolaunch must be disabled. Select “No”

• On exit, select “Do nothing”

• Check for updates, select “Never”

o MCC and MNC values reported by the device are occasionally incorrect.

o Instabilities noticed with the GSM system; e.g., data connection fails more often in GSM.

o It has been discovered that cell reselection from 2G to 3G does not necessary occur even when 3G

coverage is very good.

o With multi-device configuration when Nemo multi (USB hub) is disconnected and connected again,

all devices cannot necessarily be recognized. Each device must be separately unplugged and plugged

again to the Nemo multi hub to get them to work. It is recommended to add each device separately

to multi configuration each time.

Please see the Nemo Outdoor 6.31 Release Notes for the known issues found with the following Sierra

Wireless USB modems: Aircard 885, 306, 307, 308, 309, 310U, Siptune 215.

11.2.7.9 Sony Ericsson Handsets

• Sony Ericsson Xperia Arc S (LT-18i):

o Phone is charged via a USB data cable and charging causes interference to audio when the serving

system is GSM. Interference is cyclic and it affects the uplink MOS score with Terratec sound card.

With a fully loaded battery, the UL MOS score decreases dramatically after a 30-minute phone call.

This lasts about 30 minutes. It is highly recommended that if used in voice quality testing, the

handset is used only for observing downlink MOS scores and phone calls are made between the

handset and a fixed line with Nemo Server. In mobile-to-mobile testing, the issue is also seen in

GSM. NOTE! The issue is not seen while the serving system is WCDMA


o Multi RAB works only in this order: Voice call -> PDP context activation. If PDP context activation is

made before voice call, the test fails

o When band lock is used, the phone reboots itself. Band lock is still functioning correctly

o Driver supports Windows 7 32- bit version


11.2.7.10 ZTE Modems

• ZTE MF668A modem:

o MO voice call works when “Trace” option is selected from the device advanced properties. NOTE!

MTC calls are not supported

o MultiRAB testing can be done only if packet connection is activated before a CS call

o No indication of incoming MMS message with application tester handler

• ZTE MF683 modem:

o MO voice call works when “Trace” option is selected from the device advanced properties. NOTE!

MTC calls are not supported

o MultiRAB testing is not supported

o Device will restart and become unresponsive during the band lock command for a while, but will

recover soon

11.2.8 Qualcomm (MDM9200/ 9600)-based UEs

General Issues:

• Listed cells are not reported in idle mode

• RRC CONNECTION REQUEST message is missing occasionally

• Requested throughput is not available

• Occasionally WCDMA monitored set are shown is active set. Issue is seen with 92xx/ 96xx chipsets

• Attach/detach commands should be avoided with LTE modems. Using these commands causes instabilities in

the UEs. UEs can also reset itself. Issue is fixed to Nemo Outdoor version 6.4.1.8 but if the issue is still

experienced, the following instructions should be followed. It is recommended to choose from User

Interface Properties -> Measurement -> Force detach when going to idle mode -> No. This will prevent the UE

from detaching. If attach/ detach commands are needed frequently, for example, with script files, it is

recommended that radio off/radio on commands are used instead of attach/detach.


Figure 6. User Interface properties.

• MultiRAB testing. When a voice call is terminated, the PS data connection might be released with UEs using

the “Trace interface” call method to make voice calls. In such a case it is recommended to use “Trace

interface 2” call method.

11.2.8.1 Huawei LTE Modems

• Huawei E392/ E398 modem:

o Huawei connection manager starts up every time when device is plugged in. As a work around

connection manager .EXE file can be renamed. It still gives some reinstall warning when device is

plugged in but this can be ignored.

o Huawei E398 modem. NOTE! Nemo Outdoor 6.31 enables automatic DHCP with Qualcomm-based

devices using NDIS interface. The following procedure is required only with Nemo Outdoor version

6.30 or older.

� Before measurements can be done with Nemo Outdoor application, the Internet

protocol properties must be manually changed to automatic mode. This must be done

always after modem is disconnected/reconnected. It’s required also if the device

stops responding during measurement: Windows XP: Go to Start | Control Panel |

Network Connections, and right-click on Huawei Broadband Connection, and select

Properties. In the Local Area Connection Properties dialog, select Internet Protocol

(TCP/IP) and click on Properties. Select Obtain an IP address automatically. Select also

“Obtain DNS server address automatically”

� Windows 7: Go to Start | Control Panel | Network and Internet | Network and Sharing

Center. Select Huawei Broadband Connection in the View your active networks list. In

the Local Area Connection Status dialog, select Properties. In the Local Area

Connection Properties dialog that opens, select the Networking tab, and Internet

Protocol Version 4 (TCP/IPv4) in the This connection uses the following items view.

Click on Properties. Select Obtain an IP address automatically. Select also “Obtain DNS

server address automatically”.


Figure 7. TCP/ IP properties.


o No indication of incoming MMS message with application tester handler

o PDP context activations and deactivations with multiple Huawei USB modems occasionally cause

instability problems with dial-up connections. Avoiding these commands when using script files is

recommended.

o Huawei E392: LTE RSRQ listed not available

11.2.8.2 LG LTE Handsets

• LG P930

o The network adapter interface is not supported completely. The device can be used if the USB

tethering is enabled through the phone menu, and PS connection setting (in Nemo Outdoor) is set to

either dial-up or automatic

o If the USB connection is disconnected (i.e. device unplugged), the USB tethering must be re-enabled

on the phone in order to use the data connection

o When using the device in LTE, user must not issue manual packet session commands, instead, if the

connection needs to be torn down, user should use Radio On/Off commands

o With voice calls user must issue an "ATS0=1" AT command to enable the incoming calls. This must be

done every time the phone is restarted.

o No indication of incoming SMS

o MMS cannot be sent/ received when packet session is activated already


11.2.8.3 Pantech LTE Modems

• Pantech UML290 USB modem.

o NDIS interface can be used to make PS connection only while device is camping on LTE. NDIS

interface cannot be used with 2G or 3G connections. Instead of NDIS interface the dial up

connection should be used.

11.2.8.4 Samsung LTE Handsets

• Samsung Galaxy S III (GT-i9305, EU):

o Occasionally UE reports GSM Cell ID incorrectly

o If the UE is used with Nemo Handy prior to Nemo Outdoor, the UE must be power cycled.

o When the UE is used with Nemo Outdoor, other UEs cannot be used simultaneously in data testing if

the NDIS interface is used to activate PS data connection. For example, simultaneous data testing

with Huawei LTE modem and Samsung Galaxy S III handset is not possible. It should be noted that

the issue does not limit using multiple Galaxy S III UEs for simultaneous data testing or together with

non-NDIS UEs, such as, Nokia test terminals.

o To be able to make voice calls the “Trace interface 2” call method must be selected from Nemo

Outdoor user interface via advanced properties.

o Manufacturer information cannot be read from the UE.

o Automatic answering to incoming calls can be done only when a headset is connected to the UE.

Use the original headset included in the sales package. Connect the headset to the phone and from

the phone menu select: Settings -> Call Answering/ Ending-> Press arrow “<” on the left upper

corner to go back to previous menu. Select Settings -> Accessibility -> Call Settings -> Accessory

Settings For Call -> Automatic Answering. Automatic answering will operate only with the headset

connected.

o Auto detection should not be used to add the device. Add the device manually. See the dial-up guide

for further instructions.

o SMS/ MMS message testing not supported at the moment


o Voice quality testing is not supported with sound cards


o UE does not support WB AMR codecs

o Radio On/ Off commands are not supported

o UE is always online. This means that attach/ detach and PDP context activation/ deactivation

commands cannot be used via Nemo Outdoor.

o If data testing is done manually without script files, recording must be started before data protocols

can be accessed via Nemo Outdoor. Without recording, the data protocol options in the UI are not

available.

o If data throughputs in LTE are lower than expected, it is recommended to adjust the buffer size via

Nemo Outdoor user interface, for example, to value 1024. It should be noted that buffer size must

be adjusted separately for each protocol (e.g. for FTP and HTTP).

o Settings. The following settings should be activated from the phone:

Data testing:

� Settings -> More settings -> Mobile networks -> Mobile data enabled-> Enable

� Settings -> More settings -> Mobile networks -> Network Mode -> AUTO

• Samsung Galaxy S III (SGH-i747):


o To be able to make voice calls the “Trace interface 2” call method must be selected from Nemo Outdoor

user interface via advanced properties. NOTE! When a voice call is terminated, the PS data connection is

released. MultiRAB testing is not recommended due to this reason.



o System lock not supported. UE must be locked to certain band.


• Samsung Galaxy S III (SGH-T999):


o To be able to make voice calls the “Trace interface” call method must be selected from Nemo Outdoor

user interface via advanced properties. NOTE! When a voice call is terminated, the PS data connection is

11.2.9 LG LTE Modems (LG1000/ LG 2000)

Please see the Nemo Outdoor 6.31 Release Notes for the known issues found with the following LG LTE USB

modems: LG L1000, LG 2000, LG G7, LG G13, LG G17, LG VL600.

11.2.10 Qualcomm 3GPP2-based UEs

• If auto detection is used to add device to Nemo Outdoor the CS dial up connection should be manually

changed to “not used”. This can be done via device properties window.

• Currently MMS send functionality is supported with CDMA terminals. Received MMS messages are not

detected.

• FER F-SCH (supplemental channel) is not working correctly

11.2.10.1 LG Handsets

• LG KX206:

o Incoming calls are not automatically answered due to a limitation of the terminal.

11.2.10.2 Pantech Modems

• Pantech UM175:

o <automatic> for PS dial-up connection does not work with the device. A workaround is to create a

dial-up connection manually.

11.3 Scanner Receivers

11.3.1 Anritsu Scanners

Please see the Nemo Outdoor 6.31 Release Notes for the known issues found with the Anritsu scanner

receivers.

11.3.2 Nemo FSR1 Scanner

o GPS antenna should always be connected to scanner receiver

o GPS fix must be aqruided before starting CDMA/ EVDO scanning


o GPS fix must be be aqruided once before BSIC can be decoded. After fix is aqruided GPS connection /

fix is not needed anymore with GSM measurements

o Correlator parameter is no longer utilized by the FSR1 UMTS scanning algorithms with firmware 2.07

onwards. The user is encouraged to leave this parameter at its default value

o Please read the separate Nemo FSR1 3.0 release note for further information

11.3.3 PCTEL Scanners

• PCTEL EX scanner:

o Stopping measurement fails occasionally with EX scanners. Due to this reason starting new

measurement is failing. Workaround is to power cycle scanner receiver

o Pilot scanning works only in Top-N mode. This is a device feature

o Timeslot scanning is not supported

o The channel parameter is n/a when an empty PILOTSCAN measurement event is written

• PCTEL EX Wimax scanner:

o For Top-N preamble scanning to be successful, the scanning receiver must acquire a GPS fix at least

30 seconds before starting the Nemo Outdoor application in online mode. If the existing

configuration file includes a PCTEL WiMAX scanner, it is recommended to open the configuration file

in offline mode. If the scanner does not send any results after 30 seconds, it is recommended to

send a reset command to the scanner via the user interface.

• PCTEL EX GSM/TD-SCDMA scanner:

o Secondary frequency scanning is not supported by the scanning receiver

• PCTEL LX scanner:

o With the GSM/WCDMA scanner, the Internal GPS receiver should be activated only in UMTS mode

• PCTEL MX scanner:

o When MX scanner receiver is used with a Nemo Invex UIC module, other devices must not be

connected to the same UIC module.

o The power switch must remain in the Drive Test position at all times. The Indoor Test Mode is not

available at this time.

o USB LED does not illuminate.

o The GPS antenna needs to be connected before power up.

o Occasionally scanner device does not accept scanning configuration sent by Nemo Outdoor

application even though status is “scanning”. Device is not reporting any scanning results. In such

situations it is adviced to open device measurement properties again and press ok. Issue have been

reported to the vendor.

o Nemo Outdoor application does not detect if USB data cable is disconnected during the

measurement. “Device is not responding” message is not shown.


o Detecting and connecting the PcTel MX scanning receiver for the first time takes a much longer time.

Time depends on the number of available COM ports installed in the computer. With Win XP

computers the required time is longer than with Win7 operating system. The required time is ~2min-

10 min. It is recommend to save the hardware configuration file with Nemo Outdoor after the first

connection to the scanner receiver. Starting device with an existing hardware configuration file is

much faster.

11.3.4 Rohde & Schwarz Scanners

• TSML & TSMQ Windows 7 driver version 12.0.0.0. Please read the TSMx-NewFireWireDriver.pdf document

for further information about the installation process.

• After starting the measurement it can take up to 10- 20 seconds before the scanner receiver starts reporting

the scanning results

• The TSML and TSMQ devices might not work correctly when connected directly to the Firewire port of the

computer. If connection problems are experienced, it is recommended to use a PCMCIA express adapter card

“Firewire Express card TSPC-FW1 (415010-00)”.Problems with some Dell Notebooks. Possible problems are

caused by some of the drivers installed on Dell systems by default. The problems can be solved out by

removing the original system and re-installing the operating system only with the components necessary to

operate with the scanners.

In addition, it has been recognized that the systems which only provide 1024 bytes Host rec. buffer size

(instead of 2048 bytes) can cause issues with the scanning receivers. This can be checked from the Rohde &

Schwarz TSMx Device driver properties tab. Dell Vostro 1014 model has been found to be incompatible with

the R&S TSML-GW scanner. GSM scanning cannot be performed.

Figure 8. TSMQ driver properties.

• Rohde & Schwarz TSMQ:

o EVDO measurements can only be performed properly when a CDMA2000 channel is measured as

well. In this way, the time relationship between the different PN offsets is resolved.


• Rohde & Schwarz TSML-C:

o EVDO measurements can only be performed properly when a CDMA2000 channel is measured as

well. In this way, the time relationship between the different PN offsets is resolved.

o Simultaneous pilot scanning and spectrum scanning are not supported.

• Rohde & Schwarz TSML-G:

o Simultaneous frequency scanning and spectrum scanning are not supported.

• Rohde & Schwarz TSML-W:

o Simultaneous pilot scanning and spectrum scanning are not supported

• Rohde & Schwarz TSMW:

o If more than two technologies are measured simultaneously, the scanning device might become

unstable. Possible symptoms include the following:

� High CPU load when multiple systems are measured simultaneously. Firmware 1.09 or

later should fix the issue. It can be downloaded from

http://www2.rohde-

schwarz.com/en/products/test_and_measurement/Drive_Test_Tools/hardware/TSMW-%7C-Firmware-

%7C-23-%7C-4874.html

o In case of abnormal behavior, it is recommended to restart Nemo Outdoor. It is also recommended

to power cycle the scanning receiver.

11.4 Nemo Invex

11.4.1 General

• When shutting down the system, it is recommended to close Nemo Outdoor before turning power off from

the Nemo Invex chassis

• It is highly recommended to set the event buffer size from 100000 to 50000 when Nemo Outdoor application

is used with Nemo Invex system. This can be done via user interface properties

11.4.2 Nemo Invex USB Isolation Module

• Sierra Wireless 312/ 319 USB modem:

o After power cycling the USB modem, there have been rare occasions when the USB modem is

recognized as a hard disk drive instead of USB modem. Temporary workaround is to eject the device

via system tray. Requires remote desktop connection to UIC . Issue appears also when the USB

modem is connected directly to the USB port of the UIC module

o Device is unstable with Win 7 operating system. Issue appears with failed PDP context activations

and it also causes Windows file corruption on all processes under Windows 7 operating system. This

issue has been reported to vendor.


11.4.3 Nemo Invex UIC Module

• Nemo Invex UIC module includes preinstalled Huawei E392/ E398 driver. When plugging in Huawei E392/

E398, the OS might ask the user to install a new driver. User should choose “No” to not install a new driver in

such occasion. In case a new driver is installed, the user must do the following:

o Huawei connection manager starts up every time when device is plugged in. As a work around

connection manager .EXE file can be renamed. It still gives some reinstall warning when device is

plugged in but this can be ignored.

• When the MX scanner is used with a Nemo Invex UIC module, other devices must not be connected to

the same UIC module

• When the MX scanner is used with a Nemo Invex UIC module, it is required to wait that the

Status/Power LED of the MX scanner receiver switches to green before adding the scanner to Nemo

Invex. If the device is added to Nemo Invex before start up is completed, it can crash Nemo Invex.

11.5 Other Devices

11.5.1 GPS receivers

• In case GPS fix is lost frequently during driver test, it is advisable to turn off the car radio to see if it is

generating spurious emissions that are interfering with the GPS receiver.

11.5.2 TerraTec DMX 6Fire & Maya44 USB Sound Cards

• The sound card should be connected to a USB 2.0 port. Connecting the device to a USB 3.0 port may

cause missing MOS scores and distortion in audio, which decreases the MOS score .

• If terminals report lower than expected MOS values in Voice Quality measurements, it may result from

too high CPU usage on the computer. First of all, an Intel® Core Duo processor T2500 2.00GHz or higher

is required for voice quality measurements. If you suspect that the reported MOS values are too low

and you are using multiple terminals and a scanner simultaneously, try the following. First, if you have

many applications running on the laptop, try closing the unnecessary ones. Next, disconnect the

scanner and try testing with a single terminal to see if the MOS values improve. Proceed with testing

with 1-4 terminals without using the scanner simultaneously for optimal MOS results.

• If a sound card is used as a standalone hardware connected to a laptop, the test handsets must not be

placed close to the sound card. This applies especially to GSM.

• Turn off all sounds from the test handsets. From Windows OS, choose system sounds scheme as “No

sound”.

• Note that if there is a system that measures acceleration in the laptop and which causes the hard disk to

stop when jolted, it should be turned off. Otherwise there may be breaks in the measurement files.


With voice quality testing this can be seen with missing MOS scores, and with other test devices with

gaps in the measurement results.

Figure 9. Lenovo active protection system properties.

• Voice quality measurements using Nemo Multi Lite suitcases with Nokia terminals:

o When a Nokia terminal is placed to the holder screen facing upwards, it might cause some

interference to a sound card located at the bottom of the suitcase. This is due to the fact that the

transmitting antenna is located on the rear side of the terminal. It is recommended to place the

terminal to the holder screen facing down as seen in the picture below

o With voice quality tests Nokia 500, C5 variants, and 6720 handsets must be charged with an AC/DC

110/220V charger.

Figure 10. Nokia terminal facing down.

• Wi-Fi must be turned off from the laptop. In case stationary tests are performed, for example, in the

office, Wi-Fi base station must not be located close to the measurement system.

• With Nokia C5-03 handsets, the screen of the handset should not be activated during voice quality calls.

Activating the screen causes interference to audio and decreases MOS scores.


• Voice quality echo testing:

o The following reference sample files provided with Nemo Outdoor setup cannot be used due to too

low speech activity ratio for echo testing: 5s_nb.wav, 5s_wb.wav, 7s_nb.wav and 7s_wb.wav

11.5.3 Beceem BCS200/BCSM 250/3300 Wimax

• With some Beceem-based devices it is required to use an API version newer than the one that is by

default included in the Nemo Outdoor installation package. If a diagnostics software from Beceem

(called Kannon) or a connection manager software corresponding to the firmware of the Beceem device

is available, it is sometimes possible to use the API from one of these softwares to get the device to

work properly with Nemo Outdoor. Search for a file called libxvi010.dll in Kannon or connection

manager installation directory. Back up your existing libxvi010_524.dll in Nemo Outdoor installation

folder (C:\Program Files\Anite\Nemo Outdoor) and then overwrite it with the new version. Next, run

regsvr32 Serial_Beceem_524.dll in the Outdoor installation folder. In Nemo Outdoor select the new

device "Beceem BCS200 (524)

• RSSI & CINR values are not cleared when the level goes below -120dBm for RSSI and -32dB for CINR

• Ubee Interactive U1900 Wimax

• Connection manager software from the operator must be used to make the PS session

activation/deactivation. (FW: 5.2.3013, DRIVER: 5.2.139.0, LIB: 5.2.36. )

11.6 Applications & Protocols

• VLC media player:

o Retrieving proper error messages (streaming cause codes) is missing.

• USSD testing:

o USSD testing is not supported with Huawei and Samsung UEs.

• FTP UL data transfers:

o Occasionally FTP UL data throughput values can exceed the maximum value supported by the

network. This is seen at the beginning of data transfers. The root cause is that the operating system

can buffer the data.

• VoIP testing:

o Other PS data connections are not allowed at the same time with the same computer. Issue has

been reported to the vendor.

o Only one VoIP connection per CPU can be done at the moment. Issue reported to the vendor.

• With Nemo Outdoor 6.3 the required Microsoft Network Monitor version is 3.4.

• IP packet capturing does not work with Windows 7/ Windows Vista 64- bit versions at the moment. Due

to this reason, video streaming quality measurements cannot be performed with these operating

systems.


• If IP packet capturing is not required it is highly recommended to uninstall it, as it affects to the CPU

performance.

• WAP testing. The WAP protocol stack used in Nemo Outdoor supports the following contents:

o Content Type

� WMLC

� WML 1.1/1.2/1.2.1 text and binary yes

� WMLScript 1.1/1.2/1.2.1 text and binary yes

� WAP 2.0 /MMS

• It has been discovered that with high data rates (HSDPA 7.2Mbps), data throughput values with Nemo

Outdoor might be lower than expected. To fix the problem, it is recommended to install Windows hot

fix which is immediately available. Please see http://support.microsoft.com/kb/925681 for further

information. A too small TCP window size also lowers the maximum data throughput. By using the

TCPOptimizer utility software, it is possible to change the TCP window size and obtain better

throughputs. A good TCP window size should be 128,000 bytes. After the settings have been changed,

the computer must be rebooted to make the changes effective. The TCPOptimizer utility software can

be downloaded from the Nemo user club: (http://www.anite.com/nemo-wireless-network-

measurement-solutions-anite.html?Itemid=59) You can also request it from Nemo Helpdesk

([email protected])

• If data throughput problems are experienced with Windows Vista or Windows 7 operating systems and

you are using auto-tuning TCP receive window, please see article

http://blogs.msdn.com/wndp/archive/2007/07/05/receive-window-auto-tuning-on-vista.aspx or try to

set the auto-tuning level to highlyrestriced." Auto tuning can be restricted by running “netsh interface

tcp set global autotuninglevel=restricted” from the command prompt. We have found that the


restricted mode will often allow some of the benefits of auto tuning with a number of problematic

devices. Current auto tuning level can be shown with the command “netsh interface tcp show global”.

• With MMS testing the data transfer status can occasionally show more than 100%.

• Streaming (Catra). Nemo Outdoor cannot establish streaming with the Nemo Server Catra streaming

service. With Nemo Handy, streaming is working correctly with the included test files.

• CDMA SMS end-to-end testing. To be able to calculate end-to-end delivery time, SMS testing must be

done using the same operator between two terminals. This is due to the fact that SMS message ID

changes from operator to operator.

• MMS testing. In case of high MMS sending/receiving failures it is recommended to increase the default

time out time from 30 seconds e.g. to 60 seconds.

12 Troubleshooting Device Connectivity Issues

In general all power saving options should be disabled and high performance power settings should be used.

Battery stretch should not be used and USB port power saving option should be deselected.

13 Troubleshooting Data Transfer Issues

13.1 PS Connection Works but No Data

13.1.1 UAC Settings

• If UAC is set to always notify it might cause issues with data testing. PS connection can be established but

data transfer cannot be done. It’s recommended to change UAC settings to “Never notify”. This can be done

via User Account Control Settings. If UAC settings cannot be changed it’s highly recommended to start Nemo

Outdoor application with administration rights by right clicking Nemo Outdoor icon and by selecting “Run as

administration”.

Figure 12. UAC settings.


13.1.2 Antivirus Filtering

Disable antivirus application and Windows firewall. If data transfer still does not work, please do the following:

• Activate PS connection (activate PDP context)

• Go to Network settings and choose appropriate connection assigned for device. Go to Connection properties

and check that antivirus NDIS filtering is unchecked.

Figure 13. Connections.

13.2 Low Data Throughputs

In case lower data throughputs are received with Nemo Outdoor compared to third-party applications, read this

document for troubleshooting throughput problems with various TCP based protocols.

In case low throughput values are monitored with Nemo Outdoor and also with third-party applications, the issue can

most likely be seen by observing link adaptation parameters.

For example, low average CQI and high MAC-HS 3rd

retransmission rate indicate an area of bad coverage or high

interference. Low HS-SCCH usage rate (= high HSDPA DTX percentage ratio) points to capacity, server or transmission

problems.

In LTE networks, observe physical resource block allocation (PRB) and signal to noise ratio (SNR). PRB affects

throughput directly. Values less than maximum may indicate other users in the cell, a bottleneck in the transmission

network or not enough data to be sent (application does not need all the available bandwidth). If data throughputs in


LTE are lower than expected, it is recommended to adjust the buffer size via Nemo Outdoor user interface, for

example, to value 1024. It should be noted that buffer size must be adjusted separately for each protocol (e.g. for FTP

and HTTP).

Requested throughput much higher than the actual measured throughput may indicate that there are other users

sharing the radio resources of the cell or some other bottleneck in the network that prevents the mobile from getting

the maximum achievable throughput.

High PUSCH TX power values indicate a lack of uplink coverage.

When operating in the dynamic range of link adaptation, average BLER (PDSCH BLER) should be higher than 0, typically

10-20%, in order to achieve the gain of HARQ retransmission scheme

Residual BLER after all HARQ retransmissions should be 0%. Higher values indicate that the radio link is about to drop.

Observe the MAC downlink/uplink residual BLER (%) values.

Other things that could help troubleshooting:

• Disable any firewall and/or antivirus software that could reduce the throughput. Some HSPA USB interfaces

may also install their own software which may affect to window size settings in registry.

• Disable IP packet monitoring from the advanced properties

Figure 15. IP capture settings.

• Try another FTP server for comparison.

• Command prompt FTP throughput. This comparison is recommended because command prompt FTP does

not use any multithreading or other non-standard methods. For better results, keep Nemo Outdoor at the

background measuring the mobile network while making the transfers. Also try different servers.

• For Nemo Outdoor 5.60 and older versions: Run a script with simultaneous FTP transfers to see if the

throughput increases. Does not work manually, script is always needed.

• For Nemo Outdoor 5.70 and later versions: Use the multithread feature of the FTP protocol to test

simultaneous transfers. Works also manually.


• Make a comparison test between Nemo Outdoor and the connection manager used with the device. When

configuring a device with Nemo Outdoor, only the trace port should be defined. The modem port and dial-up

connection must be left blank. As ports are left blank it is not possible to perform a manual PDP context

activation or data transfer via Nemo Outdoor. However, a script file with data connection commands can be

used. Script files should include only data transfer commands, not Attach/detach or PDP context activation or

deactivation commands. Start a data transfer and observe the application data throughput value. Make the

same test again but this time make a connection using Nemo Outdoor.

13.2.1 All Windows Versions

∇ How to check the TCP window size from packet logs:

Using Wireshark:

1. Check the .pcap file and look at the (non FTP-DATA) TCP traffic in the middle of the transfer. Window size value tells the current TCP window size used.

Using Nemo Outdoor:

1. Open a packet grid window in Nemo Outdoor.

2. Look at the TCP traffic in the middle of an FTP transfer with PayloadLen=0:

3. Double click the frame to get detailed frame info. Look at the Tcp tree. Window shows the current

value.

Using debug logs (for developers, help desk, etc.):

4. Look for the GetWindowSizeFromRegistry() function.


• TCP Window size set to n = Value found from registry.

• TCP Window size set to default: n = Value not found from registry. Set to default.

• TCP Auto-Tuning detected. Window size not set. = Windows Vista/7 is using auto-tuning TCP

window.

5. A measurement file (.nmf) does not save window size info. Packet log and/or debug log is always

needed.

13.2.2 Windows XP

Check registry value of

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TcpipParameters\TcpWindowSize. Windows and Nemo

Outdoor both use it if it exists. The value can be changed manually or by using TcpOptimizer software. Increase value

the value if needed. If the registry value is missing, Nemo Outdoor will use its default window size which is 256 KB.

13.2.3 Windows Vista/Windows7

Windows Vista/7 does not use static window sizes from the registry. They rely on dynamic window size which is

handled by TCP auto tuning feature. However, if the same registry value that XP uses is set, Outdoor reads it and

adjusts the manual window size based on this value. In most cases, the registry has been edited by a third-party

software or a USB mobile interface driver/software. This registry entry can be removed.

If the TCP auto-tuning is disabled Nemo Outdoor will use its default window size 64 KB. Outdoor 5.40 and newer

checks the auto-tuning state and does not change any window sizes if auto-tuning is enabled.

∇ How to check TCP auto-tuning state:

1. Open command prompt by typing “CMD” to ”Search programs and files” field.

2. Type ”netsh interface tcp show global”

3. Receive Window Auto-Tuning Level shows the current state.

♦ Please note that administrator rights are required to change auto-tuning settings.


4. Open command prompt by typing “CMD” to ”Search programs and files” field. Right-click and select

Run as administrator.

Figure 16. Run as administrator.

5. To disable auto-tuning type “netsh interface tcp set global autotuning=disabled”. This limits the TCP

window size to 64KB. However, Outdoor sets its own default 256KB when auto-tuning is disabled.

6. To increase the maximum TCP window size that auto-tuning uses, type “netsh interface tcp set

global autotuning=highlyrestricted”.

7. Below are all the values of auto-tuning level with explanations:

• disabled: Uses a fixed value for the TCP receive window. Limits to 64 KB (65535).

• highlyrestricted: Recommended. Allows the receive window to grow beyond its default value,

very conservatively.

• restricted: Recommended. Somewhat restricted growth of the TCP receive window beyond its

default value.

• normal: Default value. Allows the receive window to grow to accommodate most conditions.

• experimental: Allows the receive window to grow to accommodate extreme scenarios (not

recommended, it can degrade performance in common scenarios, only intended for research

purposes). It enables receive window values of over 16 MB.

• Windows XP fix KB943198 (http://support.microsoft.com/kb/943198) is needed when using

HSDPA category 6 or higher data transfer speeds with Nokia test terminals


13.3 Issues with HTTP Browsing Testing

Selecting “Automatic configuration” or “Proxy settings” can cause problems with HTTP browsing testing, such as,

increase the page downloading time. In such a case automatic/ proxy settings should be disabled.
