5G/NR Non-Standalone Deployment: Implementation, Performance and Challenges

One Day Course (6 hours of instruction)

The Non-Standalone deployment of 5G/NR is currently one of the highest priorities of advanced Mobile Network Operators. Driven by the fierce competition, Engineering and R&D staff from both operators and vendors, not only need to assimilate the technical depth of the 5G/NR technology but are also required to ensure the tight and cost-efficient interworking of this technology with the legacy LTE infrastructure.

The goal of this course is to provide you with a thorough understanding of the fundamentals of 5G/NR, in the context of the 3GPP Non-Standalone deployment option 3. At first, the architecture, the air interface, and the 3GPP deployment options of 5G/NR are presented. Then the interworking of NR with LTE as an anchor technology is explained, focusing on radio functionality, bearer handling, mobility and performance. Two case studies will be presented to further illustrate applications of this technology. Finally, proposals for spectrum sharing between LTE and 5G/NR will be discussed.

An Introduction to Wi-Fi

One Day Course (6 hours of instruction)

Wi-Fi systems are the most widely deployed wireless technologies in the world today. Yet, they receive less attention these days than cellular technologies like LTE. Despite the fact that Wi-Fi systems carry higher volumes of mobile data, operate at higher data rates than LTE, they are almost like commodity items that people don't think too much about but rather, take for granted.

However, Wi-Fi systems are actually very sophisticated systems that were created to satisfy difficult and challenging requirements. For example, they operate in unlicensed bands, with very severe emission limits; also, they need to provide high data rates because they are in direct "competition" with wired LANs using technologies like Ethernet with super-fast rates; furthermore, in some scenarios, Wi-Fi systems are deployed in a somewhat distributed manner, without strong centralized control. Thus, challenges of interference management and resource sharing arise. Additionally, different types of traffic might need to be given different treatment (QoS), resulting in additional challenges from the resource sharing and interference management perspectives. These other technical challenges have been handled over the years (as different members of the Wi-Fi family of technologies have been created) through a variety of solutions and approaches, some of which are pretty ingenious from an engineering point of view.

We will explore these along with the solutions and approaches. Examples of such creative solutions include the various coordination functions at the MAC layer (e.g., DCF, PCF, etc.) spread spectrum, OFDM, etc., to handle challenging constraints at the physical layer while trying to achieve high data rates.

Computing in Communication Networks – From Theory to Applications

One Day Course (6 hours of instruction)

The central topic of the course is the study of architectures and protocols to enable virtualization in future communication networks, with a specific focus on mobile networks (5G and beyond).   Softwarization and virtualization are considered vital in the next generation of communication networks, as seen in the current framework of 5G as standardization moves from New Radio to the infrastructure and management aspects.  This course presents a holistic understanding of the such technologies, and it proposes both theoretical as well as practical concepts.  An extensive hands-on component is included in this course, where participants will learn how to use the discussed technologies.

The technical issues addressed by the course will include:

  • Introductory session: Presenting the reasoning on the need for computing in communication networks, this introduction will provide a picture of the evolution of networks up to present day.  Instructors will discuss 5G basics, requirements, evolution from 4G and current standardization status and beyond. The hands-on practice environment and its concepts will be also introduced during this part of the course.
  • Key theoretical concepts: The first part of this session will address Software Defined Networking (SDN) and will describe conceptual issues and design opportunities deriving from the detachment of the control plane from the data plane, network programmability, and existing solutions in the SDN eco-system (mainly OpenFlow, but with an overview of ONOS and P4).  Next the instructors will cover Network Function Virtualization (NFV),  discussing conceptual issues and design opportunities deriving from the abstraction of network functionalities from dedicated hardware, performance issues, and existing solutions for NFV (docker, OpenStack).
  • Hands-on sessions on SDN and NFV:  This portion of the course will provide participants with an opportunity to review the concepts presented earlier in the course in a practical environment.
  • Concepts and hands-on on advanced network services:  The instructors will discuss Mobile Edge Cloud, Network Coding, as well as Machine Learning and Compressed Sensing applications. Pre-defined examples in the distributed Virtual Machine will be used to illustrate the practical implementation of such concepts and enable the participants to “play” with such technologies themselves.
  • Advanced topics will be reviewed at the end of the course, allowing time for a question and answer session with the participants.

The course is the first of its kind that tries to build up a holistic understanding of the technologies supporting the development of the next generation of communication networks (e.g. 5G), and proposes both theoretical as well as practical concepts – including extensive hands-on where the attendees will learn how to use the presented technologies.

In fact, besides the theoretical subjects above, the course will also address the issues about actual deployment and implementation of such concepts, by introducing to the participants the proper open-source software tools to use for experimentation.  Details regarding the software to download and install will be shared with participants in advance of the course, so that they will are ready to participate in real-time during the hands-on experience. Practical sessions will be explored step-by-step by the instructors as well as in supplemental materials.

The course is based on a book written by the instructors on “Computing in Communication Networks,” which was recently published by Elsevier in May 2020.

LTE Fundamentals: The Essentials

One Day Course (6 hours of instruction)

LTE is the wireless cellular system that comes after 3G. Designed from the ground up as a long term evolution of the 3G systems, it came with a new OFDMA-based air interface and an All-IP Network to provide many improvements over the 3G cellular networks. Unlike earlier cellular packet technologies like HSPA (which are constrained to operate within the frameworks of 3G networks), LTE is deeply optimized for wireless data throughout all the layers of its protocol stack. In this one-day course, we review the fundamentals of LTE. Why LTE is used and how it works will be discussed.

LTE Performance and Optimization Framework

One Day Course (6 hours of instruction)

This course provides specialized information related to long term evolution (LTE) radio access network (RAN) optimization from a non-vendor perspective, providing an overview of all the aspects of the radio access network for LTE with respect to performance and optimization.

Conventionally a wireless technology course details and lists the important problems a technology solves, describes solution architecture, how it operates and specific use cases. However, this course is different than a standard technology course. This course focuses on the optimization techniques and areas to target when it comes to 4G LTE Optimization and Performance.

4G LTE is a purely packet switched network technology and it comes with its own set of optimizing challenges such coverage, interference, mobility, capacity and quality. In this course we will address how the above-mentioned performance challenges can be solved in 4G LTE Optimization.

LTE Optimization mainly refers to the pre-optimization and the continuous optimization before and after the network is launched. This course covers RAN aspects of 4G LTE Optimization starting with the six different types of key performance indicators (KPIs) defined in third generation partnership project (3GPP) standard, including topics such as how each one of these KPIs are computed, what parameters and configuration affect these KPIs, and how these KPIs can be optimized. This course also covers the practical aspects of these KPIs and how it will affect the end consumer experience.

Optimization in 4G LTE is different than 2G and 3G technology, therefore conventional optimization techniques are not applicable for 4G LTE, hence a dedicated course for LTE Optimization is more helpful to answer your 4G LTE specific questions.

Course participants will be provided with starting points to consider and to investigate whenever they are faced with a throughput optimization problem in LTE. The instructor provides practical industry wisdom on how to think and apply the knowledge in everyday optimization scenarios.

Optical Wireless Communications: Recent Applications in Terrestrial, Space, Satellite and Underwater

The course will cover the main drivers, uses, key benefits, current trends and underlying technologies around the concept of an SDN control plane focusing, notably, on transport networks and covering mainly the aggregation and core network segments.

The main part of the course will describe the main SDN concepts and functions, starting with common layered architectures, addressing both functional aspects (elements and interfaces) as well as protocol ones (stacks, encodings, formats) while presenting how common control plane functions -- resource discovery, inventory, topology and connection management – are implemented.

In particular, the course will present common trends such as the use of Openflow or Netconf/Restconf, Model Driven development, telemetry and data analytics and the use of Yang as a unified data modeling language. Existing open source projects (e.g. ODL, ONOS,..), initiatives (e.g. OpenROADM, OpenConfig) and tools / frameworks (e.g., pyang) will also be briefly introduced by means of examples.

The final part of the course will concentrate on describing more complex use case scenarios, related to the applicability to multi-domain and multi-layer networks. Architectures based on either hierarchical or peer models will be examined, highlighting issues such as scalability, topology visibility or confidentiality, and covering the concepts and roles of abstraction and orchestration. Finally, driven by the need to offer services beyond network connectivity provisioning, the course will end up discussing the current and new trends in control plane design, providing and overview of network virtualization, network slicing and the ongoing integration of SDN and NFV.

Technical Writing and Presentation for ESL Engineers

One Day Course (6 hours of instruction)

Technical writing and presentation for an engineer for which English is a second language (ESL) can at times be harder than the technical expertise the engineer attempts to convey. Without the proper communication skills in English, technical contributions could be drastically discounted and dismissed within the technical community. Beyond the known English grammar and common language usage, this course will explain the key factors to overcome cultural difference, logic inference and body language diversity.

This course will highlight the subtleties of English awkwardness in a case-by-case approach based on excerpts of reviewed papers from submissions to many international consumer electronics, communications, and computer conferences. The instructor will lead you through corrections made about the English errors, which happen more often than one would expect, even among reputable and experienced engineers.  Reconstruction in more authentic American English style will also be demonstrated.

Visible Light Communications: The High Bandwidth Alternative to WiFi

One Day Course (6 hours of instruction)

The visible light spectrum is 1000 times larger than the entire radio frequency spectrum of 300 GHz, and this simple fact provides the motivation to use visible light as a high bandwidth alternative to radio. The applications range from gigabit interconnects in data centers, through mobile networking in homes and offices to point-to-point long range wireless backhaul links outdoors. We will set the scene by looking at existing conventional wireless access technology and state clearly its limitations. Then we will go on to provide a general background to the subject of optical wireless communications, followed by a brief summary of the history of visible light communication VLC). We will discuss the relationship between VLC and LiFi (light fidelity), introducing the major advantages of VLC and LiFi and discuss existing challenges. Recent key advancements in physical layer techniques that led to transmission speeds greater than 10 Gbps will be discussed. Moving on, we introduce channel modelling techniques, and show how this technology can be used to create fully-fletched cellular networks achieving orders of magnitude improvements of area spectral efficiency compared to current technologies. The challenges that arise from moving from a static point-to-point visible light link to a LiFi network that is capable of serving hundreds of mobile and fixed nodes will be discussed. An overview of recent standardization activities will be provided. Lastly, we will discuss commercialization challenges of this disruptive technology.

Wi-Fi Security

One Day Course (6 hours of instruction)

Everyone uses Wi-Fi.  However, most people may not have a strong understanding of what the differences are between the available security options, like WPA, WPA-PSK, WPA2, TKIP, AES, etc. You may even have heard that WEP is supposed to be bad, but you are not be sure how WPA and WPA2 improve on it. Furthermore, because Wi-Fi security started from something very weak, and then was improved in stages, it can be very helpful to trace through the various generations of Wi-Fi security, and thus gain a better understanding of wireless security.

This course explains the motivations for wireless and Wi-Fi security and describes initial attempts with open authentication, WEP-based authentication, WEP encryption, etc.  We will then explore the many problems with WEP, its use of keys, etc.; and ways that it can be broken.  We’ll then discuss how WPA, as a stopgap measure, addresses some of the issues with WEP and how WPA2 is even more secure.  The IEEE 802.1X model, and the difference between PSK and enterprise modes will then be explained.
