5TEMS™ INVESTIGATION 12.0
TEMS Investigation supports more than 200 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 among users, device control functionality, intuitive
and powerful Service Control (formerly known as 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, video streaming, and VoIP.
TEMS Investigation collects data better than any product on the market.
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, video telephony, and mobile TV
(SQI, VSQI, VTQI, and MTQI), and the powerful WCDMA and GSM scanning
capabilities in the Sony Ericsson UEs. Equipment cases and backpacks contain-
ing battery solutions are among the accessories used to optimize in-vehicle,
in-building, and pedestrian-area testing.
