    Samsung Galaxy S8 and Sony Xperia XZ Premium

    Test your network with the latest devices!

    The Samsung Galaxy S8/S8+ and Sony Xperia XZ Premium are Gigabit LTE Cat. 16 ready* devices aimed for a global market. TEMS Investigation is essential for testing LTE enhancements. It includes support for:

    • Carrier aggregation
    • 4x4 MIMO
    • 256-QAM

    TEMS Investigation allows you to perform high-speed data service testing with the latest and most popular devices using on-device software clients (like Facebook, Dropbox, Netflix, Skype and Instagram) and control your device behavior (RAT lock, Band lock, Cell lock) to ensure you offer the best network experience and recruit more customers.

    * May not be available in all markets and for all mobile operators.
  • Turn-by-turn navigation

    Cloud Computing

    Cloud computing and batch installations saves time and money

    TEMS Investigation can replay and do log file export installed on a cloud computing server. Introducing support for multiple simultaneous users and instances on one computing server brings TEMS Investigation to the cloud. This saves money because you only have to pay for the amount of data power used at the moment.

    For easier and faster batch license handling and installation, an external command line interface (CLI) is added to the License Control Center. This enables administrators to by batch commands register devices, sync licenses and servers, clear licenses and export all license information to a file.

  • Prepare your network for LTE IoT

    Prepare your network for LTE IoT

    LTE NB IoT opens the door to cost efficient applications with focus specifically on indoor coverage, low cost, long battery life, and a large number of connected devices. The latest release of TEMS Investigation comes with added support for the Qualcomm MDM9206 chipset* which offers LTE Category M1 and LTE Category NB1 connectivity and enables testing of low data-rate IoT applications that use power-efficient narrowband modems. LTE Layer 3 decoding of the NB specific items in 3GPP rel. 13 and a number of Qualcomm NB specific reports is now supported.

  • Log file improvements reduces CPU and network load by 70%

    Log file improvements reduces CPU and network load by 70%

    Refined data stream in TRP logfile

    To save disk space and load on networks and CPUs during post-processing, a refined data stream has been introduced in TRP log files. It captures a selected subset of information elements and events.

    If TEMS Investigation is set to record only the refined data stream, it records all events and information elements visible in TEMS Pocket and required to generate the default report in TEMS Discovery Data Hub. This reduces file size and computer load by 70% during post-processing.

    Separate UE Collected IP capture file

    To keep the quality of measurements intact when testing higher network data speeds, a separate IP capture file can be created on the measuring device. This file will be transferred to the PC after the test has been completed which speeds up processing and saves network/USB load during measurements.
