Integrated Access and Backhaul Overview
TPR1048x | Expert-Led Live | 5G Access | 3
Course Duration: 4 hours
This training is a high-level technical overview of Integrated Access and Backhaul (IAB) - a 3GPP solution to explore higher frequencies including mmW to provide access to end devices as well as offer a backhaul transport solution for dense 4G and 5G radio networks.
Intended Audience
This course is intended for planning, engineering, and operations personnel.
Objectives
After completing this course, the student will be able to:
■ Define IAB and why it is needed
■ Sketch the IAB architecture
■ Step through the key operations of IAB
■ Identify deployment scenarios of IAB for improving coverage and capacity
