Samsung Semiconductor India Research (SSIR) has implemented an end-to-end 5G wireless signaling solution to streamline and automate 5G workflows from field to lab.

This was done at the SSIR laboratory in the Indian city of Bangalore.

Selected Keysight Technologies Signaling Field-To-Lab (S-FTL) solution to improve end-user quality of experience (QoE) by accelerating 5G field replication, analysis, and troubleshooting in a test lab environment.

Balajee Sowrirajan, executive vice president and managing director of SSIR, said the partnership helped replicate real-world field scenarios in laboratory settings and accelerated the resolution of communications and connectivity issues for customers using wireless modems.

With a comprehensive set of testing tools and techniques, the S-FTL solution enables engineers to accurately identify and resolve communication issues, Sowrirajan said.

He added that this helped reduce validation costs and shorten turnaround times.

The solution helped address voice and data issues, call switching, 5G to 4G mobility, and carrier aggregation for single-SIM, dual-SIM, and dual-connect deployments.

Analysis of field diaries

According to SSIR, the main challenge is reproducing in the laboratory the complex problems that occur in the field.

It requires analysis of field logs, which is time-consuming and complicated due to missing data or errors.

This requires a reliable test automation solution that can quickly and accurately transform field logs into test scenarios in the lab.

Furthermore, SSIR needs a solution that can reproduce field issues in the lab, freeing engineers to focus on solving problems rather than spending time analyzing logs or creating test cases.

The solution, built on a 5G protocol R&D toolkit, automates the process by analyzing field logs for 5G, 4G, and IMS, making protocol-based adjustments to ensure protocol-compliant behavior, and then replicating the field scenario as a test script.

The S-FTL solution includes an open input log template that supports a variety of formats, allowing it to be adopted in your workflow.
