Description:
The TM500 LTE test mobile is designed to address the challenges of 3GPP LTE (3G Long Term Evolution) network infrastructure development test and rollout. The TM500 LTE’s extensive Layer 1, Layer 2 and higher layer test features make it an indispensable testing peer that provides complete visibility into even the lowest layers of the radio modem by generating the detailed diagnostic data needed for engineers to verify the required functionality and optimize network operation and performance.
The TM500 LTE incorporates test, logging and measurement features at all layers of the protocol. This includes advanced MIMO tests to verify that the network appropriately handles the MIMO related signaling and correctly applies the MIMO modes, which can be realized with or without the need for an external fading simulator.
Graphical displays and charts give a visualization of the signal quality and the system status enabling engineers to quickly characterize and isolate problems. It is also possible to override signaling, or even force data corruption, to enable simulation of abnormal conditions in order to test the system response and robustness or expose difficult problems.
In the early stages of LTE development, the higher layer protocol will typically not be available and engineers must configure the physical and lower layer tests using scripts that may incorporate hundreds of LTE parameters. The TM500 LTE enables incremental testing at Layer 1, Layer 2 or higher layer levels, and together with a powerful graphical user interface (GUI), engineers can easily configure parameters and scripts to execute complex tests scenarios at different layers.
The TM500 LTE also supports full local or remote automation of test scripts, which is essential when building extensive and repeatable testing. The TM500 LTE test script configuration tool enables the easy generation and management of scripts that can then be initiated manually or by an executive test entity. The TM500 also makes it possible to alter parameters in real time to extend test coverage across a wide range of different configurations used in a live system. This enables early detection of software bugs that may not otherwise be found until much later in the development cycle when diagnosing and rectifying errors is typically much more expensive.
