What is VOLTE:- Volte (voice over lte) refers to voice calls made through a 4G LTE network rather than traditional calls made using csfb (circuit-switched fall-back), a system that switches

Many people use the terms 4g and 4g interchangeably, but they are not the same. Lets find out the difference…. Features of 4g 4G is the next step above and
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.
Terms codeword, layer, and precoding have been taken to refer specifically to LTE signals and processing. The figure shows the processing steps to which they relate. The terms used in
Currently, beam forming is only applicable for TDD version of LTE. The time synchronous version of LTE TDD on uplink and downlink also makes the implementation of beam forming more
Cell Edge Rate in LTE is simple if it’s High then Coverage Low and if It’s Low then Coverage high similar to Frequency selection. Not clear lets understand in detail.
The Hata Model for Urban Areas, also known as the Okumura-Hata model for being a developed version of the Okumura Model, is the most widely used radio frequency propagation model
LTE RAN provides the physical radio link between the User Equipment (UE) and the Evolved Packet Core (EPC) network. LTE RAN comprises eNodeBs. The eNodeB contains Transmit Receive Duplex Units
MIMO and other transmit spatial diversity scheme is a newer application than receive diversity and has become widely implemented only in the early 2000s. As the signals sent from different
SU-MIMO is one of the key technologies in LTE Rel 8. There are two major operations under SU-MIMO: transmit diversity and spatial multiplexing. Transmit diversity is an efficient way to
CSI feedback allows downlink transmission to be adaptively optimized based on the instantaneous DL channel, so that closed loop beamforming and adaptive link adaptation can be enabled to optimize the
MU-MIMO is widely considered a key technology for system capacity improvement in modern wireless networks. In contrast to SU-MIMO, where the spatial multiplexing gain is confined to a single user,
