Abstract

Narrowband Internet of Things (NB-IoT) is gaining momentum as a promising technology for massive Machine Type Communication (mMTC).

Given that its deployment is rapidly progressing worldwide, measurement campaigns and empirical performance analyses are needed to better understand the system and move toward its enhancement. In this talk, I will first introduce our first-of-its-kind large-scale NB-IoT measurement campaign.

I will then discuss the empirical analysis of NB-IoT on operational networks disclosing valuable insights in terms of deployment strategies and radio coverage performance. Next, I will focus on NB-IoT Random Access (RA) procedure and discuss how the RA procedure and performance are affected by network deployment, radio coverage, and operators' configurations. Finally, I will discuss how Machine Learning (ML) can be leveraged to enhance the RA procedure leading to significant power consumption reductions.

Bio

Özgü Alay is an Associate Professor at the Department of Informatics and lead the Gemini IoT Center at the University of Oslo. She is also a Guest Professor at Department of Computer Science at Karlstad University.

She received the B.S. and M.S. degrees in Electrical and Electronic Engineering from Middle East Technical University, Turkey, and Ph.D. degree in Electrical and Computer Engineering at Tandon School of Engineering at New York University. Her research interests lie in the areas of mobile networks including 5G and B5G, Internet of Things, low latency networking, multipath protocols and robust multimedia transmission over wireless networks.

In the last five years, she has led the effort to build MONROE, the first European open access and flexible hardware-based platform for measurements and custom experimentation on operational Mobile Broadband (MBB) networks. Currently, she is involved in building a 5G testbed through 5GENESIS project and follow-ups to test novel applications and technologies for 5G and beyond networks.
