Course Length:2 Days
Prerequisites:
A fundamental understanding of telecommunications transmission principles will be useful for students taking this course. Prior experience with Cellular based networks is recommended.
Course Objectives:
Long Term evolution or LTE is a fourth generation (4G) technology for Cellular and wireless networks. The principal purpose of LTE is to provide mobile wireless users with more bandwidth and an array of new services in future years. This course will introduce the student to LTE, how it is proposed to work and available testing methods supporting the air and data interfaces.
