Course Objectives

With the development of solid­ state electronics and its application to digital processing, telecommunication has become extremely important to large segments of global business. From a relatively stable, mature industry, telecommunication has rapidly become a technology-driven marketplace in which a host of companies are competing for customer attention with new services and equipment. The speed at which modern communication technology has been embraced and spread has connected the world in ways that were inconceivable at the start of the twenty-first century—just two short decades ago. The leap from the invention of the telephone, to the mobile phone, to the smartphone, not only changed the way we communicate but also the way we understand the world and how we operate within it.

Refreshing Telecommunications Fundamentals is a comprehensive 3 day workshop covering all important aspects of Telecom Networks, applications and services that a professional needs to know. The workshop provides an excellent grounding in telecommunications with the basics presented in clear and easy to understand format.

After successful completion of this 3 day workshop, participants will be able to

  • Understand the evolution of Telecommunications and the global trends in the telecom developments.
  • Understand mainstream wireline and wireless technologies and applications.
  • Understand the key differences among various transmission media and their associated transmission system.
  • Explain the fundamental concepts of Data Communications and IP Networking along with technologies such as, IPv6, VOIP, SIP, MPLS, Carrier Ethernet etc.
