How LTE Network Architecture?

The LTE/EPC architecture is driven by the goal to optimize the system for packet data transfer. Remember that There are no circuit switched components in LTE/EPC. There is a new

How MAC Layer work’s in Wimax?

The MAC layer is oriented to the connections. Each connection corresponds to a service flow. The service flow defines the QoS parameters of PDU transmitted over the connection. The design

Radio Bearer in LTE

There are 2 types of Radio Bearers (RB) in LTE:  To carry signaling. There are called the SRB (Signaling Radio Bearer) To carry user data. There are associated with an

What is EPS Bearer in LTE?

EPS is a connection-oriented transmission network and, as such, it requires the establishment of a “virtual” connection between two endpoints (e.g. a UE and a PDN-GW) This virtual connection is

Implementation Margin in LTE

Implementation margin is used to include non-ideal receiver effects such as channel estimation errors, tracking errors, quantization errors, and phase noise.  This implementation margin or sensitivity degradation can be used

Traffic Operation Overview in LTE

DL Data Transmission in LTE UL Data Transmission in LTE DL and UL schedulers are running in the eNodeB.  From the following inputs, the eNodeB schedules the data on the

QoS Parameters of LTE

The QoS Class Identifier (QCI) is a scalar that is used as a reference to access node-specific parameters that control bearer level packet forwarding treatment (e.g. scheduling weights, admission thresholds,

QoS Mechanisms in Packet Networks

There are Three Types of QoS Mechanisms in Packet Networks. Control Plane Mechanisms Data Plane Mechanisms Its Tradeoffs Control Plane Mechanisms Such mechanisms include QoS policy management, signaling, and admission
