5G NTN Architecture and Operations
5G_210 | Expert-Led Live | 5G Access | Expert
Course Duration: 1 day
This comprehensive full-day course on 5G Non-Terrestrial Networks (NTN) provides an in-depth exploration of the latest advancements and technical details in NTN, including architectures, air interface considerations, signaling protocols, and timing relationships. Participants will gain insights into additional considerations such as frequency pre-compensation for Doppler effect and idle measurements. This course delves into mobility between NTN and terrestrial networks (TN) as well as technical enhancements in 3GPP releases 18 and 19.
Intended Audience
A medium-level technical course for personnel involved in product management, planning, design, engineering, and operations
