LTE-AdvancedUnquestionably LTE™ R8/R9 has proved to be a great success. It is now the time for careful examination of all the technological improvements available in R10/R11/R12 along with their various implementation scenarios.

"LTE-Advanced (R10-R12)" course presents operating principles of key LTE‑Advanced features. This essential new LTE-Advanced concepts combined with students’ technical experience should allow them to form their own opinions about usefulness and applicability of specific features in the existing environment of their network and local mobile market.

In comparison to "LTE-Advanced (R10-R11)", this training contains not only brand new R12 features like Dual Connectivity, Proximity Services, eIMTA but also plenty of smaller R12 enhancements of "older" R10/R11 features and a separate section devoted to LTE/UMTS-WiFi integration.

Target audience:

The course is intended for experienced network engineers and E-UTRAN developers who are planning or have already worked on introducing LTE‑Advanced features.

Duration:

3 days.
