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.

This course is intended for planning, engineering, and operations personnel.

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
