3GPP LTE-Advanced Pro - Radio Technology

The previously scheduled course date in June 2017 has been postponed until further notise.

To benefit the most, we recommend you to combine this course with #49 "3GPP LTE-Advanced Pro - Protocol and Architecture". Please note that participants attending both course #48 and course #49 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.

LTE and LTE-Advanced is THE global standard for 4G mobile broadband systems. Higher demands for wireless data drive the continued evolution of 4G. A new standards was just defined in the latest 3GPP releases, which is called LTE-Advanced Pro and will pave the way toward future 5G systems. The continued growth of wireless data requires enhancement in spectrum efficiency, in the use of small cells and additional frequency bands (unlicensed and shared bands or very high frequencies). LTE-Advanced Pro addresses complete new markets with new systems for future Internet of Things, Public Safety, Car-to-Car communication, future Broadcast Systems as well as future wearable devices. LTE-Advanced Pro will fulfill most of the 5G requirements and will also co-exist with 5G for a long time. Actually the first phase of 5G can only be operated with an LTE-Advanced Pro eNB using Dual Connectivity.

Starting from the fundamentals of LTE and LTE-A, this training course introduces comprehensive functionality as defined in the latest LTE specifications (Rel. 12, Rel. 13 as well as current Rel.14). Techniques like Dual Connectivity that enable the deployment of dense small cells in a reliable way are explained as well as new techniques like LTE License Assisted Access (LTE-Unlicensed) and LTE / WLAN Radio Level Aggregation that leverage the use of the unlicensed spectrum using LTE or WiFi. There are also complete new systems defined for LTE Broadcast (LTE-B), LTE for Public Safety and Car-to-Car Communication (LTE-V), LTE Machine Type Communication (MTC) as well as Narrowband Internet of Things for the growing Internet of Things market. Some of these systems include significant changes to the radio access, like direct (or Device-to-Device) communication, proximity discovery or relay functionality, which are required for future Public Safety systems and also for Vehicle to X communication. The new standards for the Internet of Things include technologies for extreme coverage extension and indoor penetration as well as for ultra-low battery consumption. Overall, the new LTE-Advanced Pro standard is likely to meeting most of the requirements that are defined for 5G. Based on the shortcomings of LTE-Advanced Pro an outlook towards future 5G access networks is provided. 

The course is suitable for engineers that already work 2G/3G or 4G systems and are interested in future evolution of LTE and LTE-Advanced 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.

Any pre-existing knowledge of LTE technology and LTE-Advanced will deepen the understanding of the technical details of LTE-Advanced Pro.
