  • We can adapt this Global Communications Training Part I course to your group’s background and work requirements at little to no added cost.
  • If you are familiar with some aspects of this Global Communications Training Part I course, we can omit or shorten their discussion.
  • We can adjust the emphasis placed on the various topics or build the Global Communications Training Part I around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Global Communications Training Part I course in a manner understandable to lay audiences.

The target audience for this Global Communications Training Part I course:

  • Technical and management personnel,  researchers, hardware and software designers, defense and homeland security experts, public safety and law enforcement, and spectrum regulators, whose job requires an understanding of the evolving 5G technology and applications.

It is assumed that participants attending this Global Communications Training course:

  • Are familiar with the basic usage of a Windows computer, the Internet, and a modern Web browser such as Chrome or Firefox.
  • Students should have a working knowledge of the basic telephony and computer networking concepts (e.g. use of landline and cellular phones, and the Internet).
