LTE Core Network
SAE - Systems Architecture Evolution
Course Description
The goal of the LTE SAE from the 3GPP is to achieve a high-data-rate, low-latency, packet-optimized system that supports multiple access technologies.

Long Term Evolution, as defined in the 3GPP Release 8 standards, has described both an evolved Radio Access Network (E-UTRAN) and a new core network strategy termed SAE - System Architecture Evolution.

This is a specialized two day course which covers the major area of LTEs (Long Term Evolution) evolved core network called SAE (Systems Architecture Evolution).

The main part of SAE is the Evolved Packet Core (EPC), otherwise known as the SAE Core.

The new core network is key to achieving the level of performance that LTE must deliver with the sort of low delay across the network that has been hitherto unachievable with GPRS and UMTS.
Target Audience
Anyone needing an in-depth understanding of LTE Core Networks SAE - Systems Architecture Evolution should attend this course.

Equipment Requirements
(This apply's to our hands-on courses only)
BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
