5G Radio Protocol and Architecture

Combine this course with course #41 5G Radio Access Technology for the best learning effect. Please note that participants attending both course #41 and course #42 will benefit from a reduced total course fee of EUR 3250 (EUR 2925 for early firm registrations).

We recommend you to submit your preliminary or firm registration at least 4 weeks before course start to ensure a seat on the course.

5G has triggered a lot of research work and is extensively discussed worldwide in the wireless industry. Based on the new 5G radio access, the 5G protocol and architecture will enable new services like Enhanced Mobile Broadband, Massive Machine Type Communications and Ultra-Reliable and Low Latency Communications. The 5G architecture will not only support the new 5G radio, but also the Evolved LTE system and non-3GPP technologies. In future a terminal might even be connected via multiple access technologies simultaneously. Huge user groups transmitting infrequent small packets with very low power consumption must be supported as well as user with extremely high data rates and different latency requirements. That means the 5G radio architecture will need to be context/service aware and should also support different level of mobility. Core network architecture requirements include the support of new functions like network slicing, network virtualization and mobile edge computing. New cloud RAN solutions with centralized processing also need to support various fronthaul/backhaul options. Based on the attendance of the trainer in 3GPP, the teaching also includes updates on the latest status of 5G standardisation.

The course is suitable for engineers that already work 2G/3G or 4G systems and are interested in future evolution of the core network towards 5G. The course is held by a technical expert in the field that is directly involved in 3GPP standardization and provides a hands on up to date background information of the latest trends in this industry. Therefore it is suitable for all kind of engineers from research, development, planning, deployment and operation as well as executives, managers and system architects.

Pre-existing knowledge of the 5G Radio Access will deepen the understanding of the technical details. Therefore attendance of the preceding course #41 5G Radio Access Technology is recommended.
