Practical Fundamentals of Telecommunications and Wireless Communications

THE WORKSHOP

The make-up and structure of telecommunications networks has changed dramatically in the past few years. These changes impact on the equipment you purchase, the services you use, the providers you can choose and the means of transporting the data.

This workshop is of particular benefit to those who want to apply the latest and most effective telecommunications technology immediately. Your company may already be looking at operating its own telecommunications system or may be looking at using the systems on the market. With the vast array of equipment and systems and technology now available to you, you need the necessary knowledge to make the best decisions.
