On 14th October 2021, the IEEE AIUB Student Branch in collaboration with the IEEE Microwave Theory & Techniques Society (MTT-S) AIUB SB Chapter, successfully organized a webinar session on the celebration of the grand IEEE Day 2021 titled “Towards Flexible Radio Access Networks for Massive Connectivity in 5G and Beyond” through the virtual platform of Zoom Meeting. The core objective of the session was to enlighten the participants with the advanced technology of 5G radio connectivity covering the topics of Network Slicing, Open RAN, and Advanced Multiple Access of NOMA principles.

The event started with the elucidative inaugurating words of Prof. Dr. ABM Siddique Hossain, Advisor, IEEE AIUB Student Branch; Dean, Faculty of Engineering, AIUB, who thanked the organizer for arranging the event on an emerging topic of 5G technology. He gave a short insight into the network generation of Bangladesh and continued with the further discussion on 5G deployment, Radio Access and Terminals. Then, an official introduction was given to the esteemed speaker, S. M. Riazul Islam, Postdoctoral Fellow, Memorial University of Newfoundland and Inha University; Assistant Professor, Department of Computer Science and Engineering and Department of Artificial Intelligence, School of Software Convergence, Sejong University, South Korea by the host of the session and also requested him to take the floor for demonstrating his enlightening presentation kindly.

Mr. Islam started by thanking the Student Branch for inviting him to this grand session and portrayed a concise introduction of his affiliations along with the contents of the entire discussion. He then started with the ITU-R References of 5G recommendations and respective performance targets. Moving into the part of Network slicing, he discussed Network Slicing realization, its categories with examples, current enabling technologies, and continued with the 5G Network building blocks. After giving an insight into the Virtualized (vRAN) and Open RAN in 5G, he presented the Advance Multiple Access Technologies covering FDMA, TDMA and CDMA. In the end, the speaker focused ponderously on NOMA principles portraying the advantages, IRS-NOMA and also the Research directions on it. He concluded his speech by giving the touch of Flexible RAN for 5G and beyond, showing the Service Based Architecture (SBA).

After that, an interactive Question-Answer session took place where the speaker enthusiastically responded to all the queries of the fellow participants and illuminated their minds with further explanation. In the end, Dr. M. Tanseer Ali, Associate Professor, Dept. of EEE, Faculty of Engineering, AIUB; Former Advisor, IEEE MTT-S AIUB Student Branch Chapter shared his concluding remarks regarding the session and also presented the token of appreciation to the honorable speaker. He also invited the speaker to the charming campus of American International University-Bangladesh (AIUB) once the period of pandemic terminated all over the globe and thanked him warmly for conducting the informative webinar session. Along with Executive members and volunteers of the branch, more than 70+ participants from different universities were present in this session. The session was graced with the presence of Mr. Kawshik Shikder, Motivator, IEEE AIUB SB, Asst. Professor, Faculty of Engineering, AIUB, Dr. Mohammad Mahbub Rabbani, Associate Professor, Department of Chemistry, AIUB, and other faculty members of AIUB.
