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 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, converged IP communications, VoIP/SIP, fiber optic wavelength-division multiplexing protocols, and other advanced/emerging broadband communication technologies.

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:

  • Solidify their mastery of the concepts from Global Communications I.
  • Understand the workings of traditional phone networks.
  • Understand the wide applications of Digital (IP) Network Technology.
  • Describe the various broadband technologies used to enable digital networking.
  • Describe the capabilities and design considerations of fiber optic networks.
  • Describe the capabilities and design considerations of 3G and 4G mobile networks.
  • Describe the capabilities and applications of satellite communications.
  • Understand the capabilities of VoIP and how it differs from traditional telephony.
  • Understand the basic technologies underlying ultra-high speed (“carrier”) ethernet.
