3.2 Nemo Analyze installation

∇ Installing Nemo Analyze

Microsoft® Network Monitor 3.4 must be installed BEFORE Nemo Analyze to enable complete IP/UDP trace details to be displayed in Nemo Analyze. For installing the Microsoft® Network Monitor 3.4, see Installing Microsoft® Network Monitor 3.4 on page 93. If Microsoft® Network Monitor 3.4 is

nevertheless installed after Nemo Analyze, Nemo Analyze’s Microsoft® Network Monitor 3.4 functionality can be activated by copying the file NMAPI.dll from the folder C:\Program

Files\Microsoft Network Monitor 3\ to the folder C:\Program Files\Anite\Nemo Analyze. If

Microsoft® Network Monitor 3.4 is not found on the PC or Nemo Analyze has been installed before Microsoft® Network Monitor 3.4, Nemo Analyze will display only a limited set of IP/UDP trace details.

♦ Note: With PCAP log file decoding, the Microsoft Network Monitor that is installed must be 32-bit, even if the Windows is 64-bit.

To begin Nemo Analyze installation, insert the setup USB flash drive into the USB port. ♦ Note: The user performing the installation must have administration rights.

Installation without administration rights could result in a database error. Start installation by right-clicking the setup executable and select "Run as

administrator" from the menu.

♦ Note: Before installation, uninstall the previous version of Nemo Analyze using Add/Remove Programs from the Windows Control Panel.

Select Run from the Windows Start menu. Type D:\Nemo Analyze\ x.xx.xx.exe and press the return key. This command starts the Nemo Analyze installation software. Follow the instructions given by the installation program.

(14)

Once the installation of Nemo Analyze Setup Prerequisites has been completed, the Welcome to the Nemo Analyze Setup Wizard dialog opens. Click Next.

The License Agreement dialog opens. Select I accept the terms of the license agreement, and click Next.

(15)

The Custom Setup view opens. Click Browse and select the location where you want to install Nemo Analyze. After this, click Next.

(16)

The Completed the Nemo Analyze Setup Wizard dialog opens. Click Finish and restart the computer.

When starting, Nemo Analyze checks if the database is correct, i.e. has the same version as Nemo Analyze. If the database does not match, a warning is displayed. The warning does not prevent you from using Nemo Analyze but may cause it not to function properly.

3.3 Licensing

For Nemo Analyze you can select between two licensing options: License Server or a HASP USB key.

3.3.1 License Server (Floating License)

Licensing is separate from the product itself, therefore four options exist: Nemo Analyze Standalone with HASP USB key

Nemo Analyze Standalone with floating license

Client/Server (Enterprise) Nemo Analyze with HASP USB key Client/Server (Enterprise) Nemo Analyze with floating license

The license server option enables the use of floating license, allowing more efficient usage of

purchased licenses. When using the floating license, users do not need to have a physical HASP USB key attached into their PCs. Instead, there is only one physical USB key in the floating license server containing multiple licenses. When Nemo Analyze is started, it reserves a license over the network from the floating license server.

(17)

An unlimited amount of users in different physical locations can install Nemo Analyze, floating license only limits the amount of concurrent users. Continuous network connection is needed when floating license is used.

∇ Installing the floating license server

Install the HASP control center runtime software on the floating license server hardware. The server setup can be found from the Nemo Analyze installation USB flash drive or downloaded from the Nemo User Club´s Nemo Analyze section.

In case of Nemo Analyze Enterprise the HASP control center runtime software does not have to be installed because it is included in the Analyze Enterprise setup, just plug in the floating license dongle to server.

Plug the floating license key into the license server computer. You can verify the installation by going to http://localhost:1947/ with a web browser on the floating license server computer. You should see a red USB key in the Sentinel Keys section of the Sentinel Admin Control Center:

(18)

You are now able install Nemo Analyze. Nemo Analyze should find the floating license key

automatically from the network. After installing Nemo Analyze, go to http://localhost:1947/ with a web browser on the same computer you are installing Nemo Analyze. You should see the floating license key available over the network in the Hasp Keys and Products sections:

If you cannot see the key in Sentinel Admin Control Center, go to the Access to Remote License Managers page in the Configuration section. In the Search Parameters box, enter the IP address of the license server. Click Submit and wait for a while - the key should appear in HASP Keys section. Also check firewall settings of the license server.

(19)

Start Nemo Analyze. A dialog box informing that the key is not found appears.

Note: The license server uses a TCP/UDP port to communicate with the computers running Nemo Analyze. Please make sure that communication is allowed in the following port: TCP/UDP 1947.

Enter the IP address of the license server into Nemo Analyze. Nemo Analyze will now start with the floating license.

(20)

∇ Configuring the floating license server.

The floating license server can be configured via web browser. The address of the control center is http://localhost:1947/ when accessed from the floating license computer itself. The server can also be accessed over the network: http://<enter here the IP address of the floating license

server>:1947/.

Licenses that are currently in use can be monitored and disconnected under Sessions. Note that while one user is able to use multiple sessions, only one license is consumed per machine. To force a user to release a license, disconnect all sessions.

Under Configuration, you are able to access logging settings, set restrictions for users and configure remote access settings to the Sentinel HASP Admin Control Center. Detailed description of the license management interface can be found under Help in the side panel of the Sentinel HASP Admin Control Center.

(21)

3.3.2 HASP USB key

Nemo Analyze software license is tied to a HASP USB key and it is not possible to install Nemo Analyze without it. Software-based license is not available. A HASP USB key will be delivered in the Nemo Analyze package.

♦ Note that the new key introduced in Nemo Analyze 6.0 will not be backwards compatible with the older versions of Nemo Analyze. A new key with a valid technical support and maintenance agreement option will be in use with Nemo Analyze 6.0 and later versions.

If you have problems starting Nemo Analyze, and if the following error messages appear, please contact Nemo Technical Support at [email protected].

♦ Note: HASP USB keys are not needed when using floating license. Connecting the HASP USB key in the USB port:

Plug the HASP USB key into your computer's USB port.

Do not plug the HASP USB key into any other port. It may damage your computer.

♦ If the following error message appears, please contact Nemo Technical Support at [email protected]. The USB key battery has run out and needs to be changed.

(22)

3.3.2.1 No valid license detected

If the error message “Error: No valid license detected….” appears when the application is started, either the USB key is not plugged in or the key is an unsupported model.

Please follow the instructions for how to read the license information from the existing key. To be able to use the Nemo Analyze application supported by the old HASP USB key, it is recommended that you uninstall Nemo Analyze version 5.80. After un-installation reboot the computer and re-install the previous version.

3.3.2.2 No valid technical support agreement

If an error message stating that the version of Nemo Analyze is not supported by the technical support appears, it means that the HASP USB key type is correct, but that the key is missing valid technical support & maintenance agreement information.

Please follow the instructions for how to read the license information from the existing key with the Remote Update Utility. To be able to use the Nemo Analyze application supported by the HASP USB key without information about the technical support agreement, it is recommended that you uninstall Nemo Analyze version 5.80. After uninstallation, reboot the computer and re-install the previous version.

The old HASP USB key The new HASP USB key

The HASP USB keys are updated using the Remote Update Utility software. Before updating Nemo Analyze application please make sure that new key is available. Note that you must use the latest version of the software which comes with Nemo Analyze version 6.00, or it can alternatively be downloaded from Nemo User Club. See the instructions below for updating your Nemo Analyze USB key.

∇ Updating the HASP USB key (Nemo Analyze version 5.80 and later)

After you have received the V2C file containing the update, select the Update File in the Apply License Update tab and click Apply Update.

The HASP USB key is now updated. Nemo Analyze can be installed and is ready for use.

3.3.3 Technical support expiration

The new dongle keys used with Nemo Analyze 6.0 and later versions include a compulsory technical support and maintenance agreement option. The technical support expiration date defines the date the agreement ends. After this date it is not possible to start the new version of the Nemo Analyze application. For example: A customer has purchased Nemo Analyze version 6.0 with a 1-year technical support maintenance agreement in October 2011. The customer is entitled for free updates until October 2012. Nemo Analyze versions released after October 2012 cannot be used with the dongle key without renewing the technical support & maintenance agreement. After the technical support & maintenance agreement is renewed, the dongle key can be updated remotely and the customer can update the application to the latest version.

Ribbonbar Workspace Parameters view Workbook area

(26)

USING NEMO ANALYZE

5

In Nemo Analyze you can view measurement data in multiple ways. The most convenient way, however, is to focus on the Workspace user interface since it is quick and easy. For example, in the workspace you can double-click a parameter, and Nemo Analyze opens the parameter automatically in the default data view. Furthermore, you can go to View | Workbook | Add Data View, choose a particular data view, select a measurement, and drag a parameter from the Parameters view in the data view. You can also view several parameters in the same data view by dragging them in it. If you drag a parameter in an empty workbook, a dialog box appears and asks you to select a data view type.

If you drag a measurement file to a workbook with a data view, a dialog box emerges asking you to select the parameter you wish to view. The filter field above the Parameters view is useful when looking for a specific parameter in a long list.

All data views are synchronized with each other based on time. Consequently, if you open two or more data views on the same measurement file but on different parameters simultaneously, and switch from one point of time in one data view to another point in time, the data in the other data views change accordingly.

(27)

WORKSPACE

6

The Workspace forms the basis of the user interface in Nemo Analyze. All measurements and parameters can be found in the workspace, and from there it is convenient to drag them in various data views. See also Using Nemo Analyze. The Workspace view is by default attached to the left-hand side of the Analyze main window. You can also drag it elsewhere in the window, and if you want to dock it back to the side of the main window, double-click on the Workspace.

The Workspace view consists of eight pages: Measurements, Commander, IP Traces, Base Stations, Maps, Polygons, Data Source Files, and Reports pages, respectively. You can switch between these pages via the icon tabs at the bottom of the Workspace view.

The Measurements page in the Workspace is divided into three sections: Folders, Measurements, and Parameters. The folders include the All Measurements folder, which shows all the files that are currently in the database, and other user-defined folders. The current database connection is also identified next to the All Measurements folder, e.g. Analyze Local Database. Measurements displays a list of all measurements in the folder selected in the Folders section. The name of the measurement device is also displayed when the mouse is hovered over a measurement file.

Parameters shows all available parameters and KPIs for the selected file, measurement, or folder, depending on the selections in the other two sections. The KPIs can be displayed in graphs, maps, and other data views, and statistics can also be calculated from the Parameters view.

(28)

You can add parameters to Favorites by right-clicking on a parameter and selecting Add to Favorites from the popup menu. To toggle between the Favorites view and the Parameters view, click the Favorites button in the upper right corner of the Parameters view.

(29)

(30)

6.1 Exporting/importing favorite parameters

It is possible to export and import favorite (starred) parameters by exporting/importing identifiers of all favorite parameters.

To Export favorite parameters, select File | Settings. The Save As dialog opens. Name the file and click Save. The Export Settings dialog opens.

(31)

Select the parameter favorites you want to export and click OK. To import parameter favorites, select File | Settings.

The Open dialog opens. Open the export file (*aex) where you have saved the exported favorite parameters by selecting Open.

Select the parameter favorites you want to import and click OK. A dialog box appears asking if you want to replace existing favorites.

If user selects Yes, all favorites are cleared and new ones are imported. If user selects No, existing favorites are remembered and imported ones are added.

6.2 Workspace filters

Workspace filters enable the user to locate measurement files, parameters, maps, base stations, etc. more quickly. Below you can find some usage examples for the filters.

Above the measurement files you can find the filter for measurement files. Type the name of the measurement file in the filter field to find the desired measurement file. Above the Parameters view you can see the filter field for parameters. Type in the name of the parameter, and only parameters matching the name will be viewed in the Parameters view.

(32)

In the Base Stations view of the Workspace, the filter can find base stations based on any content in the BTS file, allowing base stations to be filtered based on e.g. channel number.

(33)

(34)

CREATING THE DATABASE

7

When you start Nemo Analyze for the first time, the database is empty. Adding files - measurements, BTS files, and maps - to the database may take a while, but once files have been added, they will remain in the database until you remove them.

For instruction on how to add CSV files to the database, see APPENDIX 2.

7.1 Adding files to the database

Select File | Measurement | Open [Measurement /Map/BTS/Report/Data Source File].

(35)

Select the file(s) you want to add to the database and click Open. You can select several files by holding down the Shift key.

From the Files of type drop down menu you can define the type of file that you want to open. Supported network measurement tools of Nemo Analyze include Nemo Outdoor, Nemo Commander, Nemo Handy, Ascom TEMS Investigation, Ascom TEMS Pocket, Ascom TEMS Symphony Suite, EADS REMS TETRAPOL, and R&S ROMES. Measurement data in CSV (Character-Separated Value) ASCII format is also supported. Marker file and map are loaded automatically from Nemo Handy embedded indoor file when downloading the file to Nemo Analyze.

♦ Note that adding files to the database may take several minutes depending on the number and the size of the files.

♦ Note that all the files need to have unique file names.

♦ Note that the file names of Nemo measurement files must follow the format filename.devicenumber.nmf (for example, t5gsm.1.nmf). Device number signifies the number of the device in case of simultaneous measurements with multiple devices. Device number must always be separated with an extra dot in the file name. With one device, the value is 1.

♦ Note that the marker file and map are loaded automatically from Handy embedded indoor file when downloading the file to Analyze.

The Activity (see Activity) displays the progress of file upload, file conversion, and file upload queue. The added measurement files will appear in the All Measurements folder in the Workspace | Measurements view in the left-hand side of the Nemo Analyze main window.

7.1.1 Migrating Nemo Analyze database to a new laptop

When changing your laptop, it is possible to migrate existing Nemo Analyze database to the new laptop once you have Analyze already installed on it. To achieve this, copy the following two subfolders from Nemo Tools folder on the C:

Nemo Analyze, with the exception of the Logs folder under Nemo Analyze (DO NOT copy the Logs folder or the database might get corrupted), and

(36)

7.1.2 Importing image files as maps

In addition to adding map files in the database through File | Measurement | Open Map, you can import image files to be used as maps. Select File | | Import | Image as map. In the Open dialog, select the image that you want to use as a map. It can be, for example, a floorplan from a test site. After selecting the image file you need to define either the width and the length of the map area in meters, or the GPS coordinates for two map corners. After you click OK in the Map Import Parameters dialog, the map is added in the database and it will appear in the Maps folder in the workspace.

(37)

You can also create black and white copies of raster maps by right-clicking on a map in the workspace and selecting Create Black & White Copy. The map is saved with the same name with ‘BW’ added at the end of the file name.

(38)

7.2 Organize measurements

By default, all added measurement files go into the All Measurements folder.

If you have a lot of files, it may be convenient to categorize measurement files into custom-made subfolders. In the Organize Measurements dialog you can conveniently handle and organize large sets of measurement files. Go to File in the Ribbonbar and select Organize, or right-click on the All Measurements folder in the Workspace and select Organize.

(39)

In the Organize Measurements dialog you can create new folders and subfolders, make joined measurements, and remove files from drag & drop folders. Right-click on a folder in the left-hand panel to create new folders. See the following chapters for information on the different folder types.

VIEWING MEASUREMENT DATA

8

Measurement data can be viewed in different kinds of data views, such as graphs, grids, numerical views, and maps. A workbook is a collection of data views and Nemo Analyze offers some ready-made workbooks for analyzing measurement data. You can also easily make your own workbooks and save them for later use.

8.1 Parameters

The fastest way to view measurement data is through the Parameters view. To open a parameter in its default view, select the relevant measurement files in the Workspace and then double-click a parameter in the Parameters view.

(62)

The selected parameter is opened in the default view. If you want to open the parameter in some other type of view, right-click on a parameter in the Parameters view and select the view type from the popup menu.

You can also drag and drop parameters in data views from the Parameters view. Nemo Analyze will display a green icon if the data view is suitable for the parameter, and a red icon if the data view is unsuitable.

In the Parameters view you can search and filter parameters by typing the parameter name in the field at the top of the Parameters view. The Parameters view will display only the defined parameters. Some parameters require further definition before they can be viewed in any given data view. When opening these parameters in a data view, a dialog box appears asking for specifications applicable to the selected parameter. For example, if you want to view RX level full selected BSIC in a graph, in the Fill Parameters dialog you can select a BSIC value from the drop-down menu in the Value field. Click Finish, select the graph type, and the parameter is displayed in a graph according to the BSIC specifications.

You can now zoom in on the map and move the current location marker on the notifications. If all the different views (line graphs, grids, maps, etc.) are synchronized, all data views will jump to the same point in the measurement, allowing you to analyze all relevant parameter data before, during and after the notification was logged.

8.3.5 Use Case 1: Viewing cell footprints, RSCP footprints, and LTE

footprints

Nemo Analyze can automatically create a cell footprint, an RSCP footprint, or an LTE footprint map plot for every cell measured. Cell/RSCP/LTE footprint is displayed for every cell whose signal has been among the three strongest at some point during the measurement session. The footprint of each cell is displayed on map on a separate page, allowing you to browse from footprint to another and

immediately see both the footprint and the cell. Cell footprint/RSCP/LTE analysis can be performed on both UMTS scanner and mobile data.

Analysis will not work properly if there will be hundreds of pages in the results. Therefore, it is advisable to use filters to limit the amount of results. To view cell/RSCP/LTE footprints, right-click a measurement file in Workspace | Measurements | Measurements, and select Analyses | Ec/NO Cell Footprints (mobile) / Ec/NO Footprints (scanner) / RSCP Cell Footprints (mobile) / RSCP Cell Footprints (scanner) / RSRP Cell Footprints (mobile) / RSRP Cell Footprints (scanner) / RSRQ Cell Footprints (mobile) / RSRQ Cell Footprints (scanner) from the popup menu.

(87)

The Analyses submenu also lists all workbooks listed in workbooks folder.

A dialog box allowing you to choose between Scrambling code filter and Channel number filter appears. You are also able to select if the color legend and the entire route is shown.

8.3.6 Use Case 2: Viewing uplink voice quality server data

This use case describes the steps for viewing uplink voice quality server data together with mobile terminal (downlink) data from the same measurement session.

Step 1: Loading Voice Quality Measurement Data into the Database

Nemo Analyze correlates the UL MOS scores automatically from the server log file to the mobile log file. A prerequisite for this functionality is that both files are loaded into the Nemo Analyze database, and that the time in server and mobile log files is synchronized in the log files. This can be

accomplished by using GPS time in the measurement tool and in the server using time synchronization services available online. See Nemo Server and Nemo Outdoor or Nemo Handy User Manuals for more information. Time synchronization can also be done manually. In time synchronization, an accuracy of around three seconds in the time sync is sufficient.

To load an uplink voice quality measurement session into the database, select File | Measurement | Open Measurement from the Ribbonbar.
