Basic Test for LTE Transmitter and Receiver Design LTE already requires fundamental changes in the base and handset and research project due to higher data rates, there is an important signal bandwidth and enhance integration and miniaturization in mobile phones, for example: Need to handle 6 different channel bandwidth from 1.4 to 20 MHz, and … Read more
Wide bandwidths concept for LTE MIMO One of the unique aspects of LTE is the support of the six channel bandwidths from 1.4 MHz to 20 MHz. To simplify system operation and roaming phones should support all these bandwidths, although effective deployment in any one area may be limited to fewer band width 20 MHz … Read more
Handover Process in LTE In LTE, the handover process involves transferring a mobile device’s connection from one cell to another seamlessly. It includes the following key steps: Measurement: The mobile device continuously measures signal strength and quality from neighboring cells. Triggering: When certain threshold values are met, a handover is triggered. This can be due … Read more
EPS provides the user with a PDN IP connectivity for Internet access and for the operation of services such as Voice over IP (VoIP). An EPS bearer is usually associated with a QoS. Multiple carriers may be set for a user, in order to provide different QoS flows and connectivity to different PDNs. For example, … Read more
The LTE related core network evolution is referred to as Evolved Packet Core (EPC). LTE architecture is based on the system architecture evolution (SAE) model defined by the 3G Partnership Project (3GPP). EPC consists of the following network elements: Mobility Management Entity The Mobility Management Entity (MME) is the LTE mobility management and session management … Read more
Here I write not all but important List of EUTRAN Capacity Limiting Factors for LTE and its definition. Impact of Interference on Capacity Interference is always a main contributor to capacity degradation in 1G to 3G cellular network and LTE is no difference. Besides external interference, there is a strong relationship also between the number … Read more
CN (SAE called EPC) is responsible for the overall monitoring of the UE and the establishment media. Main logical nodes of the EPC are: PDN Gateway (P-GW) Serving GateWay (S-GW) Mobility Management Entity (MME) Evolved Serving Mobile Location Centre (E-SMLC) In addition to these nodes, EPC also includes other logical nodes and functions like a … Read more
