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.

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.
