1. Select the Monitor Window tab2. Chose the Logfile menu3. Select Recording Properties

4. Make changes to match the below picture. Need to browse and identify the path to your log file folder.

4. Creating a workspaceIf you are provided a workspace from the customer, you can simply open that workspace and skip the following steps. If you need to create a workspace, follow the steps below:

a. Open TEMSb. Under File Menu, select “New Workspace”c. Under Presentation Menu, select the appropriate windows to display. This

will be unique for each customer and market. You have the ability to select GSM, LTE, WCDA, TD-SCDMA, etc. Under each technology, you have the option to view key performance criteria for the market.

d. Under Window option, select the appropriate window for your device to display graph and data values.

e. Once you have selected and arranged the workspace, save the workspace. This will ensure a common workspace is used for the duration of the project.

5. Creating a GeoSetA GeoSet file is used in TEMS for Navigation and or showing GPS points collected during the route. Below are the steps to follow:

a. Download the MapInfo streets required for the market, i.e. New Jersey and New York. The files are located on the Glow Networks FTP Server.

b. Move the MapInfo files into the TEM Product Files/TEMS Investigation 10.0/Maps folder.

c. Open TEMS.d. Select the Map tab.e. Select GeoSet Manager.f. Select maps to be used for market.g. Save GeoSet and close window.h. Select the Open Map Files and select the GeoSet you just created.

If you have been provided MapInfo files from the customer, move the files into the folder of step 2. Open the layer control option and add the routes provided to the GeoSet you have open.If GPS is connected, TEMS by default will track the progress of testing in the GeoSet created using the CPICH RSCP measurements. This will allow the technician to track progress, navigate and ensure all routes are covered.

You can now return to the Monitor Window and save the workspace once again. At this time, you have configured TEMS and can start testing.

6. Collecting DataWhen ready to begin testing, follow the steps below:

When needing to stop the data collection, follow steps 3-5 above and select the icon immediately to the right of the “Run” icon. The icon is “Stop” and appears as a sheet of paper with the down arrow “X” out.

IPERF COMMANDS

To perform any test cases in both LLDM and TEMS. We use command prompt called IPERF. Here are few steps to set up the IPERF and commands to be used for making the software work.

This document consists of the IPERF Commands to resolve issues with TEMS and LLDM and to make sure to get best efficient output.

For XP OS laptop:This is settings are effective for XP OS with SP3.To better results make sure the following changes are made in the Windows Registry.

Windows XP SP2 and SP3: High Priority:

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\AFD\PARAMETERSDefaultReceiveWindow ffff0

DefaultsendWindow 7fff8

All Versions of Windows XP; Low Priority on SP2 and SP3.

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\Tcpip\PARAMETERSGlobalMaxTcpWindowSize ffff0 TcpWindowSize ffff0 TcpMaxDupAcks 3 Tcp1323Opts 1 SackOpts 1EnablePMTUDiscovery 1

The DefaultReceiveWindow attribute overrides GlobalMaxTcpWindowSize and TcpWindowSize.

To optimize Vista/Windows 7.

Use the following commands in Command Prompt (Administrator) to optimize the TCP downlink conditions.netsh int tcp set heuristics disablednetsh int tcp set global rss=enablednetsh int tcp set global chimney=enablednetsh int tcp set global autotuninglevel=normalnetsh int tcp set global congestionprovider=ctcpnetsh int tcp set global ecncapability=defaultnetsh int tcp set global timestamps=disabled

To return to the default settings of a command prompt as an administrator do the following changes.

netsh int tcp set heuristics defaultnetsh int tcp set global rss=defaultnetsh int tcp set global chimney=defaultnetsh int tcp set global autotuninglevel=normalnetsh int tcp set global congestionprovider=defaultnetsh int tcp set global ecncapability=defaultnetsh int tcp set global timestamps=default

To adjust your MTU settings:

This command is used to verify the MTU settings in your Command Prompt.

netsh interface ipv4 show interfaces

To set the desire value of the network connection we need to the change the MTU value using the following commands.

netsh interface ipv4 set subinterface “The Name of your connection(ID number which is obtained from above command.)” mtu=1360 store=persistent.

Desired value for MTU can be 1360 or 1460.

Settings and Installations for IPERF commands on your system

Before starting the testing using IPERF make sure your IPERF directory is saved in the default location of your command prompt.

Example:

If your default command prompt opens with the command as

C:\User\User>

Save your file in this particular directory.

Following commands are used to execute the different test cases used for LTE site verification, benchmarking and Cluster drives.

For site benchmarking:

Telnet Setup:

ftp site: 172.26.35.82User: testftpPassword: test123bashcd /usr/local/bin

***** ALWAYS START SERVER SIDE FIRST | Change Port: "p" xxxx (5001 or higher) *****

Before you start test make sure you check the ip address whenever you connect to the network.

Note: If you are using Windows 7 operating system make sure you disable drivers signatures enforcement by using following instructions. Once you power on the system hit F7 until you see the window popping up with name of the operating system been used on the system, hit F8 once you see the window. Now select the option “Disable driver’s signature enforcement” and hit enter.

Note: Since LTE is completely new to me I tried my best to get all the information required for this LTE project in one document, before anyone has any doubts, I would recommend them to try first on www.google.com or any search engine or www.fci.org (official government website). This might help me out in adding if anything necessary in the document and learn some new technologies regarding this.
