Mobile network contains different technologies, 2G/3G network, and 4G LTE network.

Packet Switch (PS) Core Engineers are the engineers responsible for the Packet Switched Core network in both 2G/3G, and 4G LTE networks.

In 2G/3G network, the core network contains two domains, the PS (Packet Switched) domain that handles the data sessions of the users, and the CS (Circuit Switched) domain that handles the voice calls of the users.

While in 4G LTE, the core network contains only one domain, which is the Evolved Packet Core (EPC), that handles both the data sessions and the voice calls of the users.

4G LTE, is a key technology that exists in every mobile network, it contains the access network, and the core network. The core network in 4G LTE is called the Evolved Packet Core (EPC).

Therefore, having 4G LTE Evolved Packet Core (EPC) knowledge, is essential for every PS Core Engineer.

This course helps you to Become PS Core Engineer, one of the most valuable and highest paying jobs in mobile networks.
