What is the difference between LTE and VOLTE?

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

Codeword, layer, and precoding in LTE

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

Visualization of Beam Forming in LTE

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

What and How Cell Edge Rate in LTE

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.

Okumura-Hata Model for LTE

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

What is Basic behind MIMO for LTE

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

How SU-MIMO Framework in LTE Rel 8

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

MIMO Feedback in LTE Rel 8

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

How MU-MIMO Framework in LTE

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,
