Multiple input multiple output (MIMO) technologies introduced in LTE such as spatial multiplexing, transmit diversity, and beamforming are key components for providing higher peak rate at a better

Telesystem Innovations  - This article presents an overview of the LTE physical layer with a focus on essential aspects of the physical layer for FDD mode, which is the dominant mode of operat

Ericsson - Unlike previous 3GPP wireless technologies, LTE has no circuit-switched bearer to support voice, so carrying voice over LTE requires a migration to a voice over IP (VoIP) solution – commonly under the umbrella of IMS. Until this migration occurs, LTE-capable handsets need to revert to 2G or 3G for voice calls: an approach that is not ideal in the long term.

The 3GPP evolution for the 3G mobile system created the new base station system, called Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) and a new core network, called Evolved Packet Core (EPC) as a result of two standardisation projects: Long Term Evolution (LTE) and System Architecture Evolution (SAE).

“Signalling in EPC/LTE” course focuses on signalling between EPS/LTE nodes within GPRS Tunnelling Protocol (GTP) based Evolved Packet Core (EPC)* network. During the course all protocols and signalling procedures on all interfaces (i.e.
