Overview
Telecommunications is the backbone of all ITS applications. It provides the means for sending data, voice, and video information between devices. This course is a primer on telecommunications for the ITS professional with little or no formal training in telecommunications. With so many ITS projects now requiring a telecommunications aspect, this course is a must for project managers.
Objectives
Upon completion of the course, participants will be able to:
- Discuss the differences among various communications technologies used in advanced transportation management information systems
- Describe the Open Systems Interconnect (OSI) model and how it is used to define telecommunications technologies and protocols
- Explain the fundamentals of data, voice, and video communications
