Wireless Institute Colloquium – “An Overview of Cellular and Wi-Fi Standards” 2/20/18
217 DeBartolo Hall
University of Notre Dame
The purpose of this presentation is to review some basic concepts and technologies underlying the latest wireless standards and then highlight the main similarities and differences between different standards. Among the topics that will be reviewed are channel access mechanisms and some PHY/MAC features associated with the standards. Two notable examples of wireless standards are cellular and Wi-Fi standards, and we will discuss how these two standards have evolved and converged over the past years as a result of the ever-increasing demand for data. This has led to the evolution of technologies such as LTE-U, LTE/LAA, and MuLTEfire which borrow some features from both cellular and Wi-Fi standards.
Hamed Pezeshki is a Ph.D. candidate in Electrical Engineering at the University of Notre Dame. He joined the university in September 2013, shortly after earning a Master’s degree from University of Tehran, Iran. His Ph.D. is primarily focused on developing low-overhead interference mitigation techniques for interference-limited environments. As part of his Ph.D., he was also involved in prototyping one of the technologies (UL MU-MIMO) to be used in next-generation Wi-Fi (IEEE 802.11ax); which was later demonstrated in several conferences. He has two internship experiences, where his first internship was focused on developing spectrum sharing algorithms for MuLTEfire technology at Qualcomm Research in summer 2016, and his second internship was focused on tuning and analyzing the performance of next-generation Wi-Fi products at Qualcomm Atheros in summer 2017.
