Passive Distributed Antenna Systems in 3G Various internal antenna solution can meet the different needs of the deployment. DAS solution distributes a plurality of antenna nodes throughout the coverage area….
Different Tasks and States of RRC Protocol in LTE-EUTRAN The RRC protocol for EUTRAN is responsible for the basic configuration of the radio protocol stack. But one should note, that…
E-UTRAN configures a priority for all applicable frequencies for each RAT. In addition to the priorities of specific cells that are optionally provided by SI, E-UTRAN can assign specific EU…
How UE select suitable cell in LTE Here write in simple words how UE select suitable cell in LTE. After the UE has selected a PLMN, is a done selecting…
Radio Bearer in LTE In Long-Term Evolution (LTE) wireless communication, a “Radio Bearer” serves as a crucial link between the user equipment (UE) and the evolved NodeB (eNodeB), facilitating the…
The receiver is like in any other radio system the more complicated part. In radio systems and of course also OFDM there are two special points a receiver has to…
When the UE is powered up, it has to be RRC connected to be able to exchange data and signaling with the network. After the RRC connection, the Initial network…
lets talk about LTE Architecture- SERVICE, EPC, E-UTRAN and User Equipment. In the LTE network is divided into 2 basic networks, namely: 1. EUTRAN (Evolved Universal Terrestrial Radio Access Network) 2….
EPC ( Evolved Universal Terrestrial Radio Access Network) Functionally the EPC is equivalent to the packet switched domain of the existing 3GPP networks. EPC consist of:–MME (Mobility Management Entity)–SAE GW…
In the C-plane, the NAS functional block is used for network attachment, authentication, setting up bearers, and mobility management. All NAS messages are ciphered and integrity protected by the MMEand…
