Lecture  One

Topic:  5G Wireless Networking Technologies

Time:October 15th, 2018, 9:30-11:30am

Location:1011room, 2A-building, HIT

Main Content: The efficient use of transmission power and frequency spectrum have been the main focus in development of new technologies for all generations of wireless cellular communications. With the emergence of bandwidth hungry applications running on large-screen smart phones, a new focus is evolving for future 5G and Internet-of-Things (IoT) networks: Efficient traffic control. Traffic control is becoming a critical design factor in unavoidably ultra-dense cellular and mixed cellular and non-cellular wireless network scenarios. Ultra-dense networks are to overcome the problem of increasing per-user capacity and spectral efficiency by making cells smaller and bringing base stations closer to mobile hosts. With the emergence of highly delay sensitive applications such as connected vehicles and driverless cars, we need to make sure that while spectrum and energy are used efficiently, traffic load is also controlled well and the network delay is kept at extremely low levels. In this talk, the three factors of power, spectrum, and traffic load will therefore become the basis for the introduction of critical technologies to facilitate reliable and scalable operation of the 5G and IoT networks.


Lecture  Two  

Topic:  Managing Dense Cellular Networks through Software Defined Networking


Time:October 15th, 2018, 9:30-11:30am

Location:1011room, 2A-building, HIT

Main Content: The exponential growth of cellular network traffic and flattening spectral efficiency are two of the biggest challenges facing beyond 4G/5G wireless cellular networks. On the demand side, network traffic is exponentially growing and becoming much more diverse while on the supply side; the available spectrum and spectral efficiency are flattening out. One way for overcoming the problem of increasing per-user capacity and spectral efficiency is to make cells smaller and bring base stations closer to mobile hosts, thus reducing the number of users per cell and improving per link SNR. As a result, network deployments in beyond 4G/5G wireless cellular networks will inevitably become extremely dense. The current architectures are however unable to support such extremely dense cellular and wireless deployments. One way to improve the cellular network architecture is to apply the fundamentals of software defined networking (SDN) to design layers of system and abstractions that simplifies the deployment and management of extremely dense wireless cellular networks. SDN can programmatically decouple network architectures from infrastructure, thus making it easier for deploying new applications and services, as well as for tuning network policy and performance. When the SDN theory is applied, base stations perform basic packet-processing functions under the command of a logically centralized controller. Thus, SDN enables distribution of data-plane rules over multiple, low-cost network switches, hence reducing the scalability of the packet gateway and enabling flexible handling of data traffic over the cellular network. In this talk a new architecture design for future wireless cellular networks will be explored.
