2.3 CIRCUIT-SWITCHED DATA MEASUREMENTS
The circuit-switched (CS) data testing environment consists of three parts: a measurement unit (Nemo Outdoor), an application server, and a dial-up server. The dial-up server is used to establish a data connection between the measurement unit and the application server. Nemo Data Test Server can be used as the application server. It is a Linux-based administration-free server having up to four public IP addresses and it can serve multiple simultaneous TCP/IP connections from test terminals. Nemo Data Test Server supports FTP, HTTP, POP3, SMTP, and RTSP (video streaming). CS data testing is possible on all cellular technologies that support circuit-switched data.
The data measurement system has two modes: Send and Receive. In the Send mode, the measurement unit sends data packets to the application server; in the Receive mode vice versa. When an FTP server is used the measurement unit uploads (Send mode) or downloads (Receive mode) test files to or from the FTP server. When an HTTP server is used the measurement unit can only receive files. In CS data measurements, the recorded parameters include: • Number of requested and used timeslots • Requested and used coding schemes • Data call type (Non-transparent/Transparent) • Resource upgrades/downgrades during handovers • Transfer rate (every n second and average) • Packet error rate

It is a Linux-based administration-free server having up to four public IP addresses and it can serve multiple simultaneous TCP/IP connections from test terminals. Nemo Data Test Server supports FTP, HTTP, POP3, SMTP, and RTSP (video streaming). PS data testing is possible on all cellular technologies that support packet-switched data.
The data measurement system has two modes: Send and Receive. In the Send mode, the measurement unit sends data packets to the application server; in the Receive mode vice versa.
In PS data measurements, the recorded parameters include: • Data throughput • Packet error rate • Ping time • RLC/MAC data throughput • LLC data throughput • Coding schemes • RLC BLER • Attach state • GMM service state • SM information
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 10
2.5 UMA MEASUREMENTS
UMA (Unlicensed Mobile Access), the 3GPP standard for mobile/Wi-Fi convergence, is an access technology that allows a seamless handoff of mobile voice and data from a wide area cellular network to a wireless local area network (WLAN). The UMA standard defines how mobile operators can turn home, office, and public wireless LANs into seamless extensions of their cellular networks, dramatically increasing mobile service usage while decreasing costs for operators. With UMA, subscribers receive a consistent user experience for their mobile voice and data services as they transition between networks.
Nemo Outdoor, with support for UMA, is an ideal solution for operators who test and verify how subscribers can access and move seamlessly between mobile networks and WLANs. Furthermore, not only can voice services be tested, but also all mobile services including email, MMS, SMS, and other applications. At the moment Nemo Outdoor supports the Nokia 6136 UMA terminal. UMA parameters available include GAN State, WLAN Quality, QoS parameters, AMR information, LLC data rate, and URR/ URLC signaling.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 11
2.6 DVB-H MEASUREMENTS
With Nemo Outdoor it is also possible to perform DVB-H network measurements supporting various DVB-H terminals. The DVB-H (digital video broadcast-handheld) standard was derived from DVB-T, enabling lower power consumption, lower signal strengths, and fast movement, such as watching TV on your mobile while riding down the freeway at high speed. DVB-H includes a number of specific changes to the DVB-T standard to address the constraints of handheld devices, including :
• Time slicing to reduce power consumption • IP datacasting for lower-resolution video streaming • Multiprotocol encapsulation-forward error correction encoding (MPE-FEC) for more robust signal reception
• A 4K carrier mode for network optimization DVB-H is a broadcasting network, so there is no return path. The first version is based on Nokia N92, Samsung, and LG DVB-H terminals. DVB-H network operators are interesting in network coverage, as DVB-H is driven by the power of the transmitter and performance of the receiver. The cost of the network will be highly dependent on the performance of the receiver, in particular its ability to recover a signal with a poor signal-to-noise ratio (SNR) and its robustness against adjacent channel interference. Nemo Outdoor helps the operator optimize the network by enabling the measuring of all key parameters of DVB-H broadcasting. Available parameters include BER, FER, MFER (MPE-FEC frame error ratio) and RSSI.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 12
2.7 SCANNER MEASUREMENTS
Nemo Outdoor measurement system can also be equipped with a DTI or Anritsu frequency scanner. DTI scanners can be used in NMT, iDEN, ETACS, GSM, cdmaOne, TDMA, and WCDMA networks and the Anritsu scanners in GSM and WCDMA networks.
Frequency Scan mode is designed for basic frequency domain monitoring or spectrum analysis. The scanning receiver can be used in variable bandwidth modes to check the existence of wanted or unwanted radio signals in the defined frequency band. By using this mode, all the user-selected carrier frequencies of the current wireless system and their field strength values can be observed. In addition, if the Nemo Outdoor measurement system is equipped with a GPS receiver, the position information is also stored by the system. Frequency scanning results contain the field strength values for the carriers. The data collected can be used, for example, for network planning and tuning and, furthermore, for interference measurements. Depending on the cellular system technology, frequency scan mode also allows detection and measurement of other important parameters such as BSIC, DVCC, and C/I values. The DTI GSM scanner supports RXLEV and C/I measurements and BSIC decoding including MNC, MCC, Cell ID and LAC information. Pilot mode is designed for scrambling or spreading code domain analysis in WCDMA networks. In this mode, Nemo Outdoor is able to measure and decode the Pilot signal scrambling codes and their signal-to-noise ratios (Ec/No and Ec/Io values). In addition, the Primary and Secondary Synchronization Channel Ec/No can be measured. Furthermore, Pilot Channel Time of Arrival and Absolute Timing (referenced to GPS) can be observed. The complete RF signal power (RSSI) can be measured as well as the signal code power (RSCP) for each individual scrambling code.

2.8 INDOOR MEASUREMENTS
Nemo Outdoor can be configured to support measurements inside buildings. The user can choose to have Nemo Outdoor installed on a Tablet PC instead of a regular laptop. This makes the system even more portable and lightweight.
Nemo Outdoor is ideal for indoor measurements as well. Equipped with a Tablet PC, the user can plot the measurement route on a floorplan with the click of a pen.
When performing measurements inside buildings, it is not practical to use a GPS receiver for collecting location data. Therefore, the indoor measurement option offers a marker function that can be used for plotting the measurement route on the map. With a Tablet PC the user can place markers on the map with the click of a pen. It is also possible to import a bitmap image, such as, a floorplan to be used as a map.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 14
2.9 BENCHMARKING MEASUREMENTS
Nemo Outdoor Multi is a multiple test mobile holder and a general measurement device adapter to be used with Nemo Outdoor.

2.10 APPLICATION TESTING
Nemo Outdoor enables network operators to test their network using the same application protocols as their customers and, therefore, provides results that correspond with the end-user experience. Nemo Outdoor supports, e-mail, SMS, MMS, WAP, and PoC testing, FTP and HTTP file transfers, RTSP streaming, streaming video quality, voice quality measurements, video call and video call quality measurements, and ICMP ping measurements. The information provided by Nemo Outdoor assists in the verification and troubleshooting of new services reducing the time-to-market.
Application tests can be performed either manually or automatically by taking advantage of user-definable scripts. For all protocols, key performance indicators, such as, data throughput, access time, and success rate can be recorded simultaneously with the full radio network information.
All services are supported in a single product, Nemo Outdoor, providing an easy-to-use, consistent interface for configuring the different application. Different applications, such as, voice, SMS, and packet-switched data can be launched in one measurement session to simulate end-user behavior. For example, MMS testing allows you to monitor how multimedia messages are transferred in the network. MMS messages can be sent manually and with scripts. In addition to successfully sent/received MMS messages, also sending/receiving attempts and sending/receiving failures are recorded enabling statistical success rate calculations. Nemo Outdoor measures total MMS sending delay. Also separate delays from attach, PDP context activation, logging to MMSC, and message sending/receiving are recorded.

2.11 POC MEASUREMENTS
PoC (push-to-talk over cellular) is a real time one-to-one and one-to-many voice service over a cellular packet-switched network (GPRS/EDGE supported currently). With Nemo Outdoor, SIP signaling and RTP (STP) signaling is measured and messages can be decoded. Furthermore, RTP (STP) speech frames can be measured and PTT state recorded. The test terminal supported is the Nokia 6230i PoC-capable mobile.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 17
2.12 VOICE QUALITY (PESQ) MEASUREMENTS
Nemo Outdoor supports mobile-to-mobile and mobile-to-fixed-to-mobile voice quality measurements in GSM, WCDMA, and CDMA2000 networks. The measurements enable the assessment of the quality of voice during voice and video calls as perceived by end-users. Voice quality measurements are especially useful for gathering statistical data on how the network performs and for optimizing, for example, comfort noise generation or noise reduction systems. The measurement is based on the ITU-T recommendation P.862.1 and it produces a PESQ score that is mapped on an EMOS (Estimated Mean Opinion Score) scale. The supported mobiles for voice quality measurements are Nokia 6125, 6136, 6230i, 6255i, 6280, 6630, 6650, 6651, 6680, 7600, N80, LG VX8100 and LG VX8300.
The Nemo Voice Quality system setup consists of Nemo Outdoor, 1-2 mobiles, 1-2 audio modules, and the Nemo multi rack. In mobile-to-mobile measurements, one terminal is calling another and the mobiles send a test sample in one or both directions. These measurements present the combination of the uplink quality of the transmitting terminal and the downlink quality of the receiving terminal. In mobile-to-fixed-to-mobile measurements, a terminal calls a fixed number (PSTN) that is connected to a Nemo Server with the Audiotest option. These measurements present the downlink quality of the terminal at the Nemo Outdoor end, the uplink quality of the terminal at the server end, and the downlink quality of the receiving terminal.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 18
2.13 STREAMING VIDEO QUALITY MEASUREMENTS
Nemo Outdoor offers support for streaming video quality. Nemo Outdoor measures the quality of the streaming video sound and picture in real time using five different parameters: audio MOS (1-5), video MOS (1-5), jerkiness (0-100%), blockiness (0-100%), and blurriness (0- 100%). Furthermore, Nemo Outdoor saves the test video stream to a file for further analysis. Nemo Outdoor uses the perceptual evaluation of video quality (PEVQ) measurement technology provided under license from Genista. The Genista technology provides perceptual metrics and a Mean Opinion Score (MOS) for streaming video quality based on properties of human visual system, and audio quality based on human audition. All metrics work without reference signals, allowing nonintrusive, in-service measurements. Streaming video quality can be measured with all terminals that have data capabilities.

2.14 MISSING NEIGHBOR DETECTION
With Nemo Outdoor it is possible to perform real-time missing neighbor detection in GSM and WCDMA networks simultaneously. All that is required is a scanner and a mobile. A scanner scans all possible pilots whereas a mobile scans only channels that are on its neighbor list. Nemo Outdoor compares these two measurements and, based on the data, reports the neighbor channels that are seen by the scanner but are not in the mobile's neighbor list.
Nemo Outdoor displays the missing neighbors in a bar graph and also some important network parameters, such as, BCCH arfcn (channel), BSIC, RX level, difference to strongest, Ec/No, and RSCP related to the missing neighbors.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 20
2.15 IP PACKET CAPTURE
IP packet capturing is powerful feature for advanced users. With IP packet capturing, network packets sent between IP addresses are captured to log files which can be browsed with a third party application. A separate log file is generated for each terminal connected to Nemo Outdoor. The log files generated for IP packet data are compatible with Wireshark® (also known as Ethereal®). IP capturing is useful, for example, for network administrators in troubleshooting network problems and examining security problems. From the captured data it is possible to see, for example, the time between the first and last packet, the number of packets sent, the average of packets sent per second, average packet size, and delays. Ethereal® is used by network professionals around the world for troubleshooting, analysis, software and protocol development, and education. For further information please login to www.ethereal.com, www.wireshark.org.

www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 22
3 AUTOMATIC DEVICE DETECTION
Configuring and using Nemo Outdoor has been designed to provide the utmost convenience to a new user as well as to more experienced users. The automatic device detection functionality in Nemo Outdoor, accessed both through the Welcome page and the menu bar, automatically detects devices connected to the PC and assigns the appropriate, previously created COM port and dial-up information to them. As a consequence, for example, reassignment of COM ports to the devices will no longer cause confusion for the user. In addition, the user does not need to spend time on manually going through the same procedure, saving valuable time and optimizing the experience of easy and intuitive use of Nemo Outdoor.
You can do the same functions as previously, i.e. start the devices online ready for measurements, or choose to start measurements offline. The refresh button serves as a quick remedy in case of, say, accidentally lost data cable connection.
The automatic device detection functionality varies depending on the device vendor.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 23
4 NEMO OUTDOOR USER INTERFACE
Devices window Map displays the displays the selected status of the measurement measurement device and events as icons selected and the network measurement parameters. route(s) colored based on selected Graphs display selected parameter values. parameters in numerical and graphical format. Selected measurement events are displayed as icons.
Grids display, for example, selected
measurement events, layer messages, and statistics. You can also value-based parameter coloring in a grid.
The Nemo Outdoor user interface is compatible with common Windows® standards. During measurement, users can easily monitor the results and the progress of the measurement process. Through the Nemo Outdoor main window users will easily access all relevant functions. After the initial device setups and configurations the user can save all device-related settings to a hardware configuration file and load the same configuration later on.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 24
It is also possible to add parameters from the parameter tree to a data view with the convenient drag and drop functionality.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 25
4.1 MEASUREMENT WINDOWS
The measurement windows display useful information during the measurement process and during playback. Windows can be adjusted and arranged to suit the user’s working environment. View groups is a function that allows the organization of measurement windows into different tabs for easier viewing. This is especially useful when there are several graphs and maps open at the same time in the Nemo Outdoor main window. Nemo Outdoor offers several methods for viewing measurement results: line graphs are suitable for viewing parameters for which historical (past) values need to be seen, such as serving cell RSSI value, bar graphs work especially well with multiple parameters which need to be compared with each other, e.g. RSSI levels for neighboring cells, scatter plot graphs are ideal for observing correlations between two or more parameters, and delay profile graphs are a special type of graph for viewing delay profile information from CDMA systems.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 26
Grids offer more detailed information on the measurement data. Events grids list, by default, all measurement events, but the user can configure the view so that only events that are of special interest are displayed. Parameters grids display selected network parameters. Statistics grids list various statistics, such as the number of PDP context activation attempts, successes, and failures from the measurement. Messages grids are used for observing layer 2 and 3, RLC/MAC, and LLC messages. Table grids provide an easy way of simultaneously displaying the same parameter values for multiple instances. For example, the neighbor list of a serving cell can be displayed in a table grid so that each row represents one neighbor and each column represents a parameter value (e.g., system, carrier, scrambling code, etc.). In events and messages grids, the data can be analyzed even more in-depth by decoding the individual events and messages simply by double-clicking the event in question. Event and messages grids can also be color coded. Color coding can be done based on a certain message, sub channel or decoded message.
The string in decoded messages that will define which messages on a Messages grid will be color- coded with the assigned color.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 27
Furthermore, it is possible to copy grid data, such as, signaling, and export (paste) to MS Excel, MS Word, etc. for further analysis. Signaling data can be copied in non-decoded or in decoded format.
In addition, the user-defined parameters function offers more options for advanced users. A user-defined string is searched in a decoded message, and the following value is returned. The parameter can be displayed in info view and graph side panel.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 28
4.2 MAPS
When Nemo Outdoor is used with a GPS receiver and positioning coordinates are collected, the measurement route is drawn on a map and the user can easily correlate events to location coordinates. Nemo Outdoor offers parameter-based route coloring. This means that users can observe the values of certain network parameters from the route coloring on the map. Users can define which color refers to which parameter value. This way it is easy to spot the problem areas on a map. To make analysis even simpler, the same route can be drawn several times on the map and different route coloring can be applied to each of them. Also certain events can be shown as icons on the map.
Base station icons can be displayed on a map. Also, a line from the test vehicle to the serving and neighbor BTS can be drawn.
.
Nemo Outdoor maps can also display a base station overlay. With a user-defined BTS file, the map shows the location of each base station, the defined antennas with antenna directions, and even antenna apertures and cell identifying parameters. During drive testing or playback, a line connecting the current location to the serving and/or neighbor cell (sector) will be drawn
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 29
automatically (in CDMA systems, even multiple lines can be drawn to active sectors). This provides a highly visual impression of the network operation. For example, it can be instantly seen if a call is connected to a non-optimal cell.
Nemo Outdoor supports MapInfo® raster and vector maps. It also supports MapX Geoset files (.gst) which enable the user to open several layers on a map and then save them all in a .gst file to be opened later on. All user-defined map settings, such as, the order of the different map layers and the zoom factor are stored in the .gst file. For indoor measurements, you can import a floorplan and use that as a map. Nemo Outdoor supports markers, which allows the user to easily correlate events to positioning coordinates. The measurement route will be drawn on a map based on the user-defined markers. The route can be colored based on parameter values and event notifications icons can be displayed on the map.
4.3 NOTIFICATIONS
Nemo Outdoor can be configured to play audio notifications or voice prompts whenever a certain event occurs. The voice prompts are Windows .wav files, and in Nemo Outdoor both female and male default notification sounds are available. However, you can record and use your own voice notifications instead of the default files as well. The voice prompts help you during a drive testing to notice immediately when something special happens. Custom notifications can also prove useful when creating a script file. For example, the user can set a video call to start only when it is supported by a cellular technology.
www.anite.com/nemo – [email protected] NEMO OUTDOOR™ 4.21 PRODUCT DESCRIPTION 30
5 NEMO OPEN FILE FORMAT
Nemo Outdoor produces measurement files in an open ASCII file format. Files can be directly imported to Nemo analysis tool Nemo Analyze as well as to various third party post- processing/analysis tools. This is accomplished without any separate conversion or parsing of the files. Furthermore, measurement files from multiple test drives can be opened in Nemo Analyze as individual files and shown side by side or used in statistical quality survey report generator which saves the trouble of combining all measurements into one big and cumbersome file. A detailed description of the file format is included in the product user documentation. The file format description contains all recorded events and their parameters.
