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.
To understand the impact of the channel, let’s assume that the base station receiver is facing many challenges in the same MIMO receiver that universal areas, but also must receive
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.
Penetration loss in LTE indicates the fading of radio signals from an indoor terminal to a base station due to obstruction by a building. For an indoor receiver to maintain
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
SRNC and DRNC are concepts for a connected UE. The SRNC handles the connection to one UE, and may borrow radio resources of a certain cell from the DRNC. Drift
Here I write on LTE RF link budget basic but important topics and criteria to remember for coverage planning for LTE. Let’s start topics. Why Link Budget Operators are rightfully
OFDM Fundamental OFDM was selected for the downlink because it can Improved spectral efficiency Reduce ISI effect by multipath Provide better Protection against frequency selective fading OFDM is a scheme
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
