Agilent N5978A IFT Automation for TD-LTE IOT Test Plan Technical Overview Accelerate testing and reporting to TD-LTE IOT Test Plan TD Devices with four technologies: GSM, TD-SCDMA, LTE FDD and LTE TDD will co-exist for the foreseeable feature. For a positive end-user experience, UE needs to transition smoothly between these technologies while in the same time maintain acceptable performance for different applications. While conformance test is necessary, it is not sufficient to determine the user experience under different circumstances. As a result, developers and operators are increasing their focus on testing the real-world performance of UE before deploying them on live networks. The new Agilent N5978A automation scripts implement TD-LTE IOT Test Plan in Agilent's interactive functional test (IFT) software. Used in conjunction with Agilent PXT wireless communications test sets, the solution brings real-world network test scenarios into the lab environment. Simplify Your Compliance Test Process Leading TD-LTE IOT test coverage with ready-to-use test plans and reporting Unattended test with fully-automated execution and UE control Builds on Agilent IFT software and is expandable to other test plans Anticipate increasing UE performance demands impairments. Actually, you can replace those three test Network operators are motivated to ensure that instruments with an RF fader as well. performance of UE on their network results in a positive end-user experience. While signaling conformance test addresses certain aspects of functionality, operators typically want to conduct more representative performance testing under different network conditions. Examples include verifying the mobility, data throughput performance and power consumption of the UE as showed below. These real-world use scenarios supplement traditional conformance test and commonly formalized into operator- specific test plans, requiring UE be subjected to demanding compliance testing before being approved for use on an operator's network.

Schematic showing Agilent test implementation of Mobility: Data Throughput test plan, SISO Today, most TD-LTE devices are four modes: GSM, TD- SCDMA, LTE FDD and LTE TDD or even five modes: GSM, Power Consumption: WCDMA, TD-SCDMA, LTE FDD and LTE TDD. Mobility test End-user are frustrated with the short battery life of their is required to verify the UE behaves as expected when smartphones and wireless data devices during real-world transition between different radio access technologies. operation, making battery drain a top issue for wireless Mobility test includes cell selection/reselection, intra-LTE device designers and service providers.
