5G and Beyond Wireless Networks: When All Technologies Work Together for Good
By: Prof. Octavia A. Dobre
Memorial University, Canada
With the approval of the non-standalone 5G New Radio (NR) specifications at the end of 2017, and the standalone 5G NR specifications to be completed in 2018, 5G is becoming a reality. While continuing to address the ever increasing demand for high data rates and ubiquitous connectivity, as well as provide mobility support, 5G and beyond wireless networks also aim to accommodate a massive number of devices, with different traffic characteristics. Enhanced mobile broadband, massive machine-type communications, and ultra-reliable low-latency communications are the three pillars of these networks. To satisfy their wide requirements in terms of capacity per area, peak and user experienced data rate, spectral and energy efficiency, mobility, connection density, reliability, latency and security, innovative technologies have been explored by both industry and academia in the most recent years.
The talk will provide an overview of 5G networks, emphasizing the use cases for the three mentioned pillars, the standardization timeline, and the enabling technologies. Advantages and challenges of adopting different such technologies, such as full duplex and non-orthogonal multiple access, will be underlined. Machine-type communications will be discussed as an important driving force of future wireless networks, which allow the expansion of the mobile ecosystem to other industries like energy, healthcare, transportation, and agriculture. Finally, in an attempt to answer the question “Quo vadimus,” research directions are highlighted for the dynamic and exciting field of wireless networks.
