  In this video, you’ll learn more about your instructor and this course. In this course, you’ll approach 5G network architecture and design concepts from a high level. You’ll review cellular mobile communication networks, their components, and architecture, and then you'll dive deeper into some of the technologies that empower 5G's revolutionary potential. You’ll also learn how 5G is expected to coexist with 4G during an initial transition period. FREE ACCESS
• 2.  Mobile Communications Network Cellular Architecture
  7m 20s
  In this video, you’ll learn more about mobile communication networks. These networks are complex and multifaceted. They involve different components, each of which performs a particular function. Here, you’ll learn the main components of a mobile communications network. You’ll begin by looking at a network diagram of a typical mobile communications network. You’ll see the network is composed of the devices that connect to the network wirelessly. FREE ACCESS
• 3.  Core Cellular Network and Backhaul
  7m 15s
  In this video, you’ll learn more about the core network. This is the component which interconnects all of the other major components of a mobile communication providers network. The core network delivers user data to the internet and connects voice callers to their colleagues and their loved ones. The core network and the backhaul are the backbone of a cellular provider's service, and their capacities directly affect the capacity of the network. FREE ACCESS
• 4.  Radio Access Network and its Part in 5G Architecture
  6m 27s
  In this video, you’ll learn more about the radio access network, or RAN. This is the part of the mobile communications network that conceptually resides between the wirelessly connected device, such as a smartphone or a sensor, and the core network. It connects the device to the network and ensures the device has the level of service and features delivered by 5G. The RAN consists of the base station subsystem, transceivers, and baseband electronics. FREE ACCESS
• 5.  MIMO and Massive MIMO in 5G Enablement
  7m 24s
  In this video, you’ll learn more about multiple-input multiple-output, or MIMO. You’ll learn this is a method of multiplying the capacity of a radio link using multiple transmission and receiving antennas to take advantage of a physical phenomenon known as multipath propagation. For 5G however, the extension of MIMO, called massive MIMO, plays a vital role in its revolutionary capabilities. FREE ACCESS
• 6.  The Anatomy of a Cell in a 5G Network
  6m 19s
  In this video, you’ll learn more about the major advantages of the architecture of a 5G network. You’ll learn that this architecture incorporates multiple cell sizes. Higher frequency ranges used by 5G along with higher capacities and higher bandwidth density requirements led to a hierarchical cellular structure of the network. 5G has introduced various cell types whose primary distinguishing factor is their size. Here, you’ll look at the various cell types and their purposes. FREE ACCESS
• 7.  NFV and SDN for 5G Network Slicing
  7m
  In this video, you’ll learn more about network slicing. To understand this pioneering innovation, it is important to first understand the technologies that make it possible. These technologies include software-defined networking and network function virtualization. Traditional network design and administration involves the use of specific network devices like routers, switches, and firewalls. There are physical connections between the devices and each one is configured separately. Connect them all together for a traditional network. FREE ACCESS
• 8.  5G Network Slicing
  7m 36s
  In this video, you’ll learn more about network slicing. You’ll see that much like SDN and NFV, network slicing is an abstract concept and that’s difficult to visualize. It makes use of abstractions that themselves are difficult to grasp. You’ll learn how this approach functions and its significance to 5G. Slicing is virtually segmenting the original physical network infrastructure into multiple independent networks. Each network segment or slice is configured to meet specific service requirements.

• 9.  How 5G and 4G Must Coexist
  7m 45s
  In this video, you’ll learn more about how 5G and 4G can coexist. The transition to 5G involves a process that entails the coexistence of 4G and 5G networks for a certain amount of time. This transition period is different than previous transitions from one generation to the next. As with any transition from generation to generation, there’s a period where technologies must co-exist to ensure a smooth changeover from one technology to another. FREE ACCESS
• 10.  What Is a Protocol Stack?
  9m 6s
  In this video, you’ll learn more about protocol stack. Communication from one device to another is described in terms of a protocol stack. 5G uses a specific protocol stack that defines the way communications over a network take place. First, you’ll learn what a communication protocol stack is, and how it can be helpful to understand the operation of 5G. FREE ACCESS
• 11.  The 5G Protocol Stack
  6m 12s
  In this video, you’ll learn more about new radio or NR. This is the term given to the radio access technology that delivers 5G service to end-users. This is called the air interface, and it describes the methodology involved in connecting and communicating on a 5G network. New radio and its protocol stack were designed to be the global standard for connectivity of 5G networks. FREE ACCESS
