4G is the cutting-edge network technology that links millions of smartphones to the internet. But how does it actually work?
Ideal for network engineers, sales engineers, application developers, and many other telecoms pros, this course will help you to understand the technology behind the apps and devices we use every day.
You’ll get a solid overview of LTE/EPC (Long Term Evolution / Evolved Packet Core) 4G networks, how they work, how the network architecture is designed, and which protocols are used.
First, you’ll gain exposure to the global architecture of the network, how the radio interface works, and how security is guaranteed.
Then you’ll dive into the operational side. What is a bearer? How is it quickly configured and released? How does 4G handle millions of terminals that are on the move all the time?
Over the next few years, the advent of 5G will see over 20 billion mobile terminals go online.
By mastering the key concepts of 4G, you can be ready for the next chapter in mobile networking—and the jobs of the future.
Whether you’re a graduate student or already in a professional role, targeting a career move or just building your skills, you’ll gain plenty of detailed, practical knowledge that you can put into practice immediately.

This course is designed to encourage educators to develop new creative habits that foster personal learning networks, content creation, and innovative learning practices that embrace curiosity, failure and reflection. Each week a new creative habit is explored through the examination and understanding of one’s own relationship to creativity. The goal of this class will be to increase awareness of personal creativity, to encourage new learning connections in an online environment, to enhance self- expression, and to increase confidence in the use of digital tools through project based activities. Participants are encouraged to share and interact to facilitate a connectivist attitude, get feedback from their peers, and to forge meaningful and personalized ideas about what living a creative life is all about. Educators will be encouraged to tap into their own creative potential while drawing on the synergy created by participating in a creative learning community. Join us in exploring the power and richness of creativity in our lives. Our hope is that participants will not only draw new meaning and strength from this process, but in turn will provide active and empowering contributions in their own learning communities.
