ACE Telecom 4 Getting Started ACE TELECOM welcomes you to this concise tutorial/document on Drive Testing using TEMS Investigation GSM. It is the leading air-interface test tool for Wireless Networks. Getting started gives a quick overview of the TEMS Investigation user interface. The working of the TEMS INVESTIGATION is described in more detail in the later part of the document. Workspace and Worksheets The entity that stores all the windows and settings used in a working session is called the workspace. Only one workspace can be open at a time. To manage your windows more smoothly, you can divide your workspace into several worksheets. Up to ten worksheets can be active simultaneously. Toolbars Through the toolbars all the central functions are accessible. Most of the toolbar buttons are mirrored in the menus. Navigator From the Navigator, you can open presentation windows, change the color ranges of information elements, and manage your worksheets. The Navigator is especially useful for configuring the workspace at the beginning of a session. . . ACE Telecom 5 Menu Bar The menus mirror most of the toolbars as well as the Navigator's Menu and Worksheets tabs. Status Bar The Status bar displays symbols and short messages that indicate the current status of the application. . . ACE Telecom 6 Setting your TEMS INVESTIGATION software This chapter deals with preliminaries that you must work through before you can start using TEMS Investigation, such as configuring your TEMS software and connecting external equipment like GPS and TEMS mobile station. 1) TEMS Investigation can be opened by choosing: StartÆProgramsÆTEMS ProductsÆTEMS Investigation GSM 5.1. 2) Now go to the Map Worksheet by clicking MAP tab at the bottom of the TEMS Investigation window. 3) Next thing now is to zoom into the country or city where you want to drive test and add sufficient layers. 4) Adding Layers(for example area map, drive route or any other layer) a. Adding layers is simple. Just click the Layer Control button at the top of the Map window. b. Layer Control window will appear and you can easily add new layers (tab files) by clicking on the Add button and browsing your folders for the required layer.(Remember to keep the layers above the ocean and also the map layer) c. The new layers will be visible on the Map window as soon as you click OK. 5) Adding Cellfiles (cellfile contains the cell information in the network like Cellname, Cell id, direction, ARFCN, BSIC, LAC, etc) a. Click on the configuration tab at the bottom of the TEMS Investigation window. b. Now go to the window named GENERAL and double click Cellfile Load (highlighted in the snap on the right). c. Another window will appear named PROPERTIES (as seen in the snap below). Check on USE CELL DEFINITION FILE. And then browse for the folder where you have saved the latest cellfile d. After loading the cell file click OK on the properties window and go back to the MAP window to check whether the cellfile has been loaded. Your TEMS Investigation is now ready to be used and next step is to connect external equipment like TEMS and GPS. . . ACE Telecom 7 Setting up and connecting External equipment Connecting TEMS Mobile Station 1) Place the external antenna at the roof of your drive test vehicle. It is magnetic and will stick easily to the rooftop. 2) Connect the connector of the antenna to an adaptor(a wire) that will lead to the jacket of the TEMS mobile station. 3) Now place the TEMS MS into the jacket. 4) The TEMS MS is now ready to be connected to the laptop via USB data cable. 5) Connect the TEMS MS to your laptop ports. When you have plugged an external device (MS or GPS) into a PC port, you must perform two steps in TEMS Investigation before you can start using it: first to enable the device, then to connect it (in an abstract sense of the word). From now on in this chapter, the word "connect" when used by itself refers to the operation carried out within the application, not to connecting the device physically to the port. Enabling can be done in two ways: either for all devices at once, using the Identify Equipment function (Automatic), or for each device separately (Manual). But its always a nice practice to connect manually. 6) Automatic enabling can be done by going to the Port configuration window in the Configuration Tab and clicking IDENTIFY EQUIPMENT button . 7) Manual enabling (preferred to avoid port conflicts) is done using the buttons that looks like this . (this enables one device at a time) a) When you click the manual enable button a window will appear named ADD EQUIPMENT. b) In the Port combo box you select the correct COM port. (In our case it’s the one other than COM3 and COM16) c) Under Equipment you select the type of external device. Choose "T610" for the TEMS MS and it will appear as an MS device. d) You can repeat step a, b, c for connecting more than one tems. . . ACE Telecom 8 8) To connect a single external device(TEMS): Choose the device in the combo box of the Equipment Control toolbar (at the top of TEMS Investigation). And Click Connect on the Equipment Control toolbar. 9) To connect all external devices: Click Connect All on the Connections toolbar. Connected devices are accompanied by a green-light symbol in the combo box. The same symbol appears in the status bar and in the Port Configuration window. Note: If you have a logfile opened, you must close it to be able to connect equipment. 12) If you want to leave an external device plugged into the port, but disconnected in the application for the time being: Choose the device in the toolbar combo box. Click Disconnect on the Equipment Control toolbar. To disconnect one external device. Click Disconnect All on the Connections toolbar. For a disconnected device, the symbol representing it reverts to red. . . ACE Telecom 9 Connecting GPS 1) Connect the GPS to the laptop via the data cable. 2) Manually enable the GPS (as said before manual enabling is preferred to avoid port conflicts) using the ADD button which looks like this . a) When you click the manual enable button a window will appear named ADD EQUIPMENT. b) In the Port combo box you select the correct COM port. (In our case its COM16 because the PCMIA card is already configured at COM16). c) Under Equipment you select the type of external device. Choose "NMEA0183" for the GPS and it will appear as a GPS device. 3) To connect a single external device: Choose the device in the combo box of the Equipment Control toolbar (at the top of TEMS Investigation). And Click Connect on the Equipment Control toolbar. 4) To connect all external devices: Click Connect All on the Connections toolbar(or press shortcut key F2). Connected devices are accompanied by a green-light symbol in the combo box. The same symbol appears in the status bar and in the Port Configuration window. Note: If you have a logfile opened, you must close it to be able to connect equipment. 5) If you want to leave an external device plugged into the port, but disconnected in the application for the time being: Choose the device in the toolbar combo box. Click Disconnect on the Equipment Control toolbar. To disconnect one external device. Click Disconnect All on the Connections toolbar. For a disconnected device, the symbol representing it reverts to uploads/s1/ dt-concise-guide.pdf
