TEMS™ iNvESTiGATioN 9.1

DATA CoLLECTioN

TEMS  Investigation  supports  more  than  130  phones,  scanners,  PC 

cards, USB modems, and Fixed Wireless Terminals from all major vendors 
across multiple technologies, which can be used to collect geographically 
positioned data from a user’s perspective.

Features such as automatic detection of devices, customizable work-

spaces that can be shared between users, device control functionality, pow-
erful command sequences to control and automate data collection, event 
audio  indications,  and  real-time  data  presentation  make  data  collection 
simple and effective.

In TEMS Investigation, multiple devices can be connected and can run 

simultaneously to minimize the time spent collecting data. In addition to 
traditional  RF  data,  L2/L3  messages,  and  IP  information  collection,  TEMS 
Investigation supports testing of CS and PS services including voice, video 
telephony, FTP, HTTP, Ping, e-mail, WAP, MMS, SMS, and video streaming.  

TEMS Investigation collects data better than any product on the mar-

ket.  In  addition  to  standard  parameters,  it  employs  specially  developed 
algorithms to collect information that other vendors’ tools cannot. These 
include  service  quality  algorithms  for  voice,  video  streaming,  and  video 
 telephony (SQI, VSQI and VTQI), and the powerful WCDMA and GSM scanning 
capabilities in the Sony Ericsson UEs. 

Backpacks containing battery solutions and equipment cases are some 

of the accessories used to optimize in-vehicle, in-building, and pedestrian-
area testing.

PoST-PRoCESSiNG FUNCTioNALiTy 

TEMS Investigation can be used to process and analyze logfiles from 

TEMS Investigation, TEMS

 Pocket, and TEMS

 Automatic. 

More than 1,000 information elements (IEs) and 150 events can be 

presented in more than 100 predefined presentation windows. This flexibil-
ity allows users to change presentation windows to match specific require-
ments and optimize the analysis view for different tasks. Own events can 
be defined in order to locate problem areas. All presentation windows are 
synchronized and all settings are saved in workspaces that can be reused 
or shared between users.

TEMS Investigation supports replay of logfiles and simultaneous analysis 

of multiple logfiles. The tool contains features and predefined tasks to filter 
data and perform daily analysis of coverage, handover, calls, and user-de-
fined event counters. For advanced users, a scripting interface ensures full 
flexibility and accessibility to the collected air interface data.
