# 4G LTE Cell ID (ECI) Calculator

This Page provides information about 4G LTE Cell ID (ECI) Calculator. Calculator is based on 3GPP TS 29.405 Release 17 specification.

When working with 4G LTE networks, understanding how to calculate the Cell ID, also known as the E-UTRAN Cell Identity (ECI), is essential for various network management tasks. The 4G LTE Cell ID (ECI) is a unique identifier utilized in LTE networks to distinguish individual cells. It comprises a 28-bit value consisting of two parts: the eNodeB ID (20 bits) and the Sector ID (8 bits). The ECI plays a vital role in network planning, optimization, and troubleshooting tasks, enabling network engineers to analyze cell characteristics, performance indicators, coverage areas, and potential interference sources.

Calculator will help you to convert the E-UTRAN Cell Identifier (ECI) to eNodeB Id + Sector ID and back (eNodeB Id + Sector ID to ECI).

Step-by-Step formula to use 4G LTE Cell ID (ECI) calculator:

1. Select a mode of calculator: E-UTRAN Cell Identifier (ECI) —> eNodeB Id + Sector ID or E-UTRAN Cell Identifier (ECI) <— eNodeB Id + Sector ID
2. If select first mode then enter ECI (Example: 27624711), if select second mode then enter eNodeB Id (example: 107909) and Sector Id ( Example: 7)
3. Get result of Calculation: eNodeB Id (example: 107909) and Sector Id ( Example: 7) or ECI (Example: 27624711)

In the context of LTE (4G) networks, ECGI (E-UTRAN Cell Global Identifier) and ECI (E-UTRAN Cell Identity) are both identifiers used to uniquely identify individual cells. However, they serve different purposes and have different formats.

The ECGI is a globally unique identifier assigned to each LTE cell within a specific operator’s network.
It consists of two parts: the PLMN ID (Public Land Mobile Network Identifier) and the ECI. The PLMN ID identifies the operator or network, while the ECI identifies the specific cell within that network. The ECGI is typically used for network management, handover procedures, and core network-related operations.

The ECI is a unique identifier used within an LTE cell to differentiate individual cells from each other. The eNodeB ID identifies the LTE base station (eNodeB), and the Cell ID identifies the specific cell within that base station. The ECI is mainly used for radio access network (RAN) operations, including cell-specific measurements, performance monitoring, and optimization tasks.
