At ABB, we help industries outrun - leaner and cleaner. Here, progress is an expectation - for you, your team, and the world. As a global market leader, we'll give you what you need to make it happen. It won't always be easy, growing takes grit. But at ABB, you'll never run alone. Run what runs the world. This Position reports to: R&D Team Lead Time synchronization (TS) is essential for a plethora of automation use cases, e.g., farming and unmanned vehicles. However, achieving an accurate TS over wide-area wireless networks, such as 5G, is challenging due to, e.g., device mobility and large areas to cover. To accommodate TS needs, wireless networks introduce special features and mechanisms. This thesis is to study and evaluate how a case-study wireless network supports TS. Details Period: January/February - June/July 2026 (5 months) Number of credits: 30 ECTS Number of students for this thesis work: 2 Location: On-site at ABB Corporate Research in Vasteras Your role and responsibilities Study a time synchronization (TS) solution called Precision Time Protocol (PTP) Analyze key features and mechanisms of wireless networks that enable a high TS accuracy Evaluate performance of PTP over a real-world wireless network under different test conditions Research questions: What time accuracy can be obtained for the case-study wireless network? What is a major factor impacting PTP performance therein? Approach: Review literature on PTP and its support in wireless networks Configure PTP server and clients to work with a real-world wireless network Define and realize methodology for PTP performance evaluations Conduct performance measurements in the case-study wireless network and analyze them Qualifications for the role General understanding of wireless networks and principles of their operation Basic knowledge of time synchronization and TS protocols such as NTP or PTP Good hands-on skills in computer networking, a networking integration experience is advantageous Good spoken and written English More about us Supervisor Ognjen Dobrijevic, ognjen.dobrijevic@se.abb.com, will answer all your questions about the thesis topic and expectations.
