Global Communications II

Group Training + View more dates & times


This course builds off the knowledge gained by the student in the pre-requisite course: Global Communications I. The course begins with a review of the packet network communications concepts, technologies, standards and applications learned in Global Communications I. It then proceeds to dive deeper into these technologies to achieve a better understanding of important communication protocols and standards and their applications. Finally, large scale global communications technologies are explored, such as Multi-Protocol Label Switching (MPLS), Carrier Ethernet (CE), satellite communications systems, broadband communication technologies and Global Navigation Satellite Systems (GNSS) used for Location Based Services (LBS).

Who Should Take This Course


It is assumed that participants attending this course:

  • Have attended the course Global Communications I, or have the equivalent knowledge and experience from that course.
Why You Should Take This Course

Upon completion of this course, the student will be able to:

  • Expand on the concepts of packet-switched networks covered in Global Communications I, including how global routing scales across the Internet
  • Understand how Virtual Private Networks (VPNs) protect data transported over the Internet
  • List the advantages with using Multi-Protocol Label Switching (MPLS)
  • Understand the concepts of the IEEE 802.1Q Virtual LAN bridging standards
  • List the different Carrier Ethernet virtual connection services and describe the characteristics of each one
  • Describe the capabilities and applications of satellite communications systems.
  • List the different key technologies that provide broadband access and compare the advantages and disadvantages of each
  • Understand how Position, Navigation and Timing (PNT) is provided by today’s Global Navigation Satellite Systems (GNSS) and list the four systems
