5G Principles: Comparing 5G to 4G

IN THIS COURSE

• 1.  Course Overview
  1m 40s
  In this video, you’ll learn more about the course and your instructor. In this course, you’ll learn more about 5G by comparing it to 4G. You’ll see how 4G has paved the way for 5G, not only technologically, but in other ways as well. You’ll learn that focusing on the differences will give you more insight into the technological leaps being made by 5G and the related applications that became a reality as a result. FREE ACCESS
• 2.  A Look Back at 4G
  7m 5s
  In this video, you’ll learn more about 4G. You’ll learn that when 4G was first rolled out in Sweden in 2009, it was hailed as a new era of mobile telecommunications. In 2008, the radio communications sector of the International Telecommunications Union, known as the ITU-R published the official requirements of 4G. These requirements defined the thresholds a mobile network must achieve in order to have the right to be called a truly 4G network. FREE ACCESS
• 3.  Did the World Really Need 4G?
  5m 38s
  In this video, you’ll learn more about 4G. You’ll discover 4G once promised speeds of 1Gb/s for stationary or slow-moving mobile devices. At the time, average broadband speeds were at 3.87Mb/s. It wasn't until 2014 that the 10Mb/s threshold was broken. It wasn’t until around 2017 that 20Mb/s was reached. You’ll see a graph onscreen that shows this progression between 2007 and 2017.

• 4.  Paving the Way for 5G
  5m 4s
  In this video, you’ll learn more about 5G. You’ll learn 5G networks started their rollout in the early 2020s. At the time, there were still many 4G deployments that outperformed the new 5G networks. Towards the end of the 2010s, 4G as a technology matured enough to deliver a greater level of service. This was achieved through the implementation of new technologies into the 4G standard. It paved the way for 5G. FREE ACCESS
• 5.  The Driving Force behind 5G
  3m 15s
  In this video, you’ll learn more about 5G. You’ll learn about 5G's primary driving force. It came from new and innovative applications that are either in development or ready to be deployed. The timing of the advent of these technologies coincided with the transition between 4G and 5G. Speed is one of the most profound benefits of 5G over 4G and one of the most marketable. FREE ACCESS
• 6.  Moving from 4G to 5G: Speed
  4m 21s
  In this video, you’ll learn more about 5G. You’ll learn for 5G, speed has been proven to be a good marketing hook. It has ensured telecoms are competitive enough to gain 5G subscribers, to fund their further rollouts of 5G networks. While speed may never be used to its fullest potential by average smartphone users, it’s the incentive that brings in the subscribers needed to ensure physical rollouts of 5G are cost effective.

• 7.  Moving from 4G to 5G: Latency
  10m 46s
  In this video, you’ll learn more about 5G and latency. You’ll learn that latency is a phenomenon seen on all types of networks. It’s a measure of how long information takes to traverse a network. This is different than sheer speed, which is a measure of the volume of data that traverses the network per second. Latency or network delay is the time it takes data to travel from its source to its destination. FREE ACCESS
• 8.  Moving from 4G to 5G: Slicing
  5m 37s
  In this video, you’ll learn more about 5G and slicing. You’ll discover network slicing is another concept that is leveraged to deliver improved network performance for 5G mobile communication networks. Over the past few years, there has been an emergence of different applications, requiring a diverse set of network capabilities. These have been identified in a previous learning path called 5G Principles Fact and Fiction. FREE ACCESS
• 9.  Moving from 4G to 5G: Flexibility of Deployment
  8m 22s
  In this video, you’ll learn more about 5G and the flexibility of deployment. Another concept introduced by 5G that is unique to this generation is the architecture of its physical deployment. This has to do with the frequency ranges assigned to be used by 5G. 5G has been assigned a series of frequencies primarily found within two bands, named Frequency range1 and Frequency range 2. FREE ACCESS
• 10.  Technical Challenges to the Deployment of 5G
  6m 39s
  In this video, you’ll learn more about 5G and its deployment. You’ll learn there have been many technical challenges in the way of 5G’s deployment. These challenges must be addressed and resolved to make it a viable and practical technology. These include frequency allocation, backhaul capacity, as well as geographical and topological obstacles. FREE ACCESS
• 11.  Sociopolitical Challenges to the Deployment of 5G
  3m 25s
  In this video, you’ll learn more about the challenges to 5G and its deployment. You’ll learn 5G’s rollout was not only affected by technical challenges associated with the technology, but also by social and political challenges. These have to do with public sentiment, political will, and the preservation of natural habitats and historical districts. FREE ACCESS
• 12.  Course Summary
  1m 51s
  In this video, you’ll summarize what you’ve learned in the course. You reviewed 4G to understand how 5G developed. You also looked at the forces driving 5G today and compared those with the forces that drove 4G. You also examined the various advantages of 5G, including latency, slicing, speed, and flexibility of deployment. You also looked at the various technical and social challenges associated with the rollout of 5G networks. FREE ACCESS
