IEEE Computational Intelligence Society (CIS) Shenzhen Chapter

The number of devices requesting for wireless communications is growing exponentially. Network densification via the deployment of many base stations (BSs) of different types is one of the mechanisms that can be employed to satisfy the ever-increasing demand for bandwidth/capacity in wireless networks. However, deploying fiber to the small cells may be expensive and impractical when the number of small cells increases. For this reason, as well as because of the traffic jams and infrastructure displacements caused by fiber optic installation, millimeter wave (mmw)-based wireless backhaul is currently considered as an alternative, providing (almost) the same rate as fiber optic with significantly less price and no digging. With this background, integrated access and backhaul (IAB) networks, where the operator can utilize part of the radio resources for wireless backhauling, has recently received considerable attention. The purpose of IAB is to replace existing backhaul systems with flexible wireless backhaul using the existing 3GPP bands providing not only backhaul but also existing cellular services in the same node. This creates more flexibility and reduces the implementation cost. For 5G NR, IAB is currently considered as a work item in 3GPP, and it is known as one of the main novelties of 5G. In this talk, we review the main backhauling techniques, and present the main motivations/standardization agreements on IAB. Moreover, We present comparisons between the IAB networks and the cases where all or part of the small access points are fiber-connected. Finally, we study the robustness of IAB networks to environmental effects and verify the effect of the blockage, the tree foliage, the rain as well as the antenna height/gain on the coverage rate of IAB setups, as the key differences between the fiber-connected and IAB networks. As we show, IAB is an attractive setup enabling 5G and beyond. Speaker(s): Behrooz Makki, Virtual: https://events.vtools.ieee.org/m/272959

Dr Arslan has graciously offered to continue the discussion on 5G technologies. The topic is Flexible Radio Access Beyond 5G: A Future Projection. Abstract: Today's wireless services and systems have come a long way since the rollout of the conventional voice-centric cellular systems. The demand for wireless access in voice and multi-media applications has increased tremendously. The trend on the variety and the number of mobile devices along with the mobile applications will certainly continue beyond 5G, creating a wide range of technical challenges. One of the biggest challenges is the security of the communication beyond the classical crypto based approaches which secure the information. In this talk, security aspects of the physical communication and also physical signal which is called Physical Layer Security (PHY Security) will be discussed. Latest trends, threats, and techniques to improve the security of the physical signal will be discussed. The tentative outline of the talk will be as follows: - Wireless Communication trends, requirements - Importance of secure communication - Classification of communication security - PHY security: Communication and REM - PHY security: Eavesdropping, Spoofing & Jamming - Anti-jamming capable communication - Cross-layer security - Secure communication & other advanced radio access technologies Case- studies: a- Security in URLLC (URLL & Secure communication) b- Security in vehicular network (V2V and V2I) c- Security in NOMA d- Security in LIS Speaker(s): Dr. Arslan Arslan, Atlanta, Georgia, United States, Virtual: https://events.vtools.ieee.org/m/277084

IEEE YP Professional Development Series: Part 7 The Professional Development Series is a 10-part series of online seminars which aims at presenting and discussing career opportunities and pathways in the engineering profession, with presenters coming from a wide range of backgrounds across Canada and the world. In Part 7, Michael Lalonde will discuss how one can use their soft skills learned throughout their life experiences and successfully apply them to advance in their professional career.
