Here we discus about LTE Technology, detail on 4G and How to LTE.
The Various steps to control inter-system interference include: 1. external Filters, add the transmitters and receivers 2. Antenna isolation between transmitters and receivers of victims 3. the distance between transmitters and receivers of victims 4. Reduce transmission power 5. Guard band between operators Step 1 is probably the most common technical solutions. This can have … Read more
Passive device bi-directional couplers and combiners. Splitters route signals different frequencies that are present on the same supply line into separate lines for each frequency. Adders perform the same function in reverse order. They accumulate signals of different frequencies that are present on separate feed lines on one channel line. They support the nominal impedance of … 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
NAS procedures, especially procedures for managing connections, essentially similar to UMTS. Main change UMTS is that the EPS allows the union of certain procedures to ensure a more rapid establishment of communication and media. MME creates a context of the UE, when the UE is turned on and attaches to the network. It allocates a … Read more
LTE access network and E-UTRAN, the network comprises a eNodeBs, as shown in Fig. For the normal user traffic (as opposed to transmission), there is no centralized controller in E-UTRAN, thus, E-UTRAN architecture is called flat. The eNodeBs are usually inter-connected together through an interface known as X2, and the EPC interface through S1 – … Read more
