What is ECGI LTE?

What is ECGI LTE?

The E-UTRAN Cell Global Identifier is used to identify cells globally. The ECGI is constructed from the MCC (Mobile Country Code), MNC (Mobile Network Code) and the ECI (E-UTRAN Cell Identifier).

What is cell ID LTE?

The physical cell ID (PCI) is used to indicate the physical layer identity of the cell. The PCI is used for cell identity during cell selection procedure. The purpose of PCI optimization is to ensure to a great extent that neighboring cells should have different primary sequences allocated.

How is ECI calculated in LTE?

ECI

  1. E-UTRAN Cell Identifier (ECI). Used to identify a cell uniquely within a Public Land. Mobile Network (PLMN). The ECI has a length of 28 bits and contains the eNodeB-IDentifier (eNB-ID).
  2. In short, it is used to identify a cell within a PLMN.
  3. ECI = eNodeB-ID + Cell-ID.

What is mod3 LTE?

This means that for every PCI=X, any other PCI with value of X+3(n) – where “n” is an integer, will have a collision on Reference Signal between the two ports. This is known as the PCI mod3 issue.

What is an eNodeB in LTE?

E-UTRAN Node B, also known as Evolved Node B (abbreviated as eNodeB or eNB), is the element in E-UTRA of LTE that is the evolution of the element Node B in UTRA of UMTS. Traditionally, a Node B has minimum functionality, and is controlled by a Radio Network Controller (RNC).

How can I calculate my LTE ID?

There are 168 possible Cell ID groups and 3 possible Cell ID sectors; therefore, there are 3 * 168 = 504 possible PHY-layer cell IDs….Cell ID (LTE)

  1. Cell ID sector 0 = ZC Root Index 25.
  2. Cell ID sector 1 = ZC Root Index 29.
  3. Cell ID sector 2 = ZC Root Index 34.

What is eNodeB in LTE?

What is PCI conflict in LTE?

As a LTE network may contain a much larger number of cells than the 504 available values of PCIs, the same PCI must be reused by several cells. However, the User Equipment (UE) cannot distinguish between two cells if they both have the same PCI and frequency, a situation called as PCI conflict.

What is LTE function?

LTE (Long Term Evolution) is the project name given to development of a high performance air interface for cellular mobile communication systems. It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks.

What is the function of MME in LTE?

The mobility management entity (MME), which presents a key control node for the LTE access network, manages UE access network and mobility, as well as establishing the bearer path for UE’s.

Which tower is my phone connected to?

Network Cell Info Lite (for Android) This highly-rated free Android app uses crowdsourced 4G and 5G tower location data from Mozilla Location Services. Once you open the app, go to the “map” tab. You’ll see nearby towers, and the app will draw a blue line to the tower you’re connected to.
