Packet Core Intermediary Course (PCIC) Description

PCIC covers the intermediary level knowledge of Packet Core in the Mobile Network and it is made up of three main modules: System Architecture, Interfaces & Protocols and Traffic Cases.

Packet Core Network is that part of the mobile telecom network which handles data and internet services from 2G all the way to 5G technology.
