How many simultaneous WCDMA data connections does TEMS Investigation support?

[kenchi31]

Hey everyone, can you please tell me how many simultaneous WCDMA data connections does TEMS support?

I´m using three and sometimes I have problems, but i don´t know if it´s a network problem or if the problem comes with TEMS.

Thank you

I guess the issues are between TEMS and Windows - I'm having the same problems. It's more stable in Windows 7 but still... not perfect.

Here are some details that should be take care of before starting TI




You should not have any software installed that periodically scans COM or USB ports, for instance Microsoft Outlook synchronization software such as Sony Ericsson PC Suite or Nokia PC Suite. The reason is that such software may cause difficult connect problems in TEMS Investigation Data Collection.

Please note that hard disk encryption software, firewalls, virus scanners, and other security products may prevent multiple RAS sessions from being maintained concurrently, thus interfering with data service testing. Contact your IS/IT department for assistance in these matters.
The realtime scanning feature of antivirus software is prone to generate considerable CPU load. If you find the overall CPU load excessive, it may be a good idea to try turning off the realtime scanning feature.

You should make sure that the computer used for measurement and recording does not go into any kind of standby mode:
•
Never put the PC in Sleep mode.

•
Disable the Windows screen saver under Control Panel → Display → Screen Saver. In the same dialogs, make appropriate settings under “Energy saving features...” so that these features are never activated during measurement.

•
Disable any other screen savers.

(If the PC does go into standby, it may be necessary to unplug your data collection devices and plug them in again.)

USB Legacy Support must be turned off in BIOS. For information on how to do this, please consult the user manual for your computer.


The built-in software firewall in Windows Vista and Windows XP must be disabled.
Windows Media Player and other applications that attempt to synchronize to removable mass storage devices (such as mobile phones) must be disabled. They may otherwise interfere with data collection.

It might be the conflict between different dial-ups in Windows. Try to use different FTP addresses or file names.

When you use two or more data conections the downlink is don why the hardware of the computer i dont remember , but is share the downlink, i test with two mobiles with hsdpa and always is the same.

Hi

You are referring to 3 connections on 3 UEs? not multiRAB?

In General, I never use more than 2 or 3 UEs + Scanner with TEMS. On a good computer maybe you can run this, but for me, it's too much and I end up running 2 phones most of the time. With 3 phones I get random problems, random disconnects etc and everything runs slower.

For the test in some cofigurations use the hsdpa and r99 connection and i dont have problems :
MS1 Scanner UMTS PCTel Seagull
57 NO Load MS2 Short Video (CS 64) A501 Only UMTS 60 sec. 15 sec pause.
58 MS3 Long Video (CS 64) A501 Only UMTS Infinito. Mobile to mobile (in static place if possible) Video DCR (normalised), DL BLER
MS4 PS R99 only DL ZX10 Only UMTS 2MB DL.
MS5 HSDPA Only UL Sierra A875, ZX20 or LGMU500 Only UMTS 2MB UL

5 HSDPA connections working - tested.
Unplug brandmazer windows on each connection and uses different ftp and different file names.
