What is CGI in telecom?

Cell Global Identity (CGI) is a globally unique identifier for a Base Transceiver Station in mobile phone networks. It consists of four parts: Mobile Country Code (MCC), Mobile Network Code (MNC), Location Area Code (LAC) and Cell Identification (CI).

What is LAC and cell ID?

LAC means Location Area Code, which is a group of cell towers. And CID stands for Cell Identification, referring to the cell number and sometimes a sector. In other words, the CID tells you where the antenna is located and which direction it faced.

What is LTE cell ID?

A Physical Cell Id (PCI) is the identifier of a cell in the physical layer of the LTE net- work, which is used for separation of different transmitters. Due to the construction of PCIs, the number of PCIs are limited to 504.

What is cell ID used for?

CellID (CID) — is a generally unique number used to identify each Base transceiver station (BTS) or sector of a BTS within a Location area code.

What is cell ID in 5G?

In 5G, a service provider identifies a cell using an NCI (NR Cell Identity). This is a 36bit identity which can be concatenated with the PLMN-Id (PLMN Identifier) to form the NCGI (NR Cell Global Identity).

What is an eNB ID?

evolved NodeB IDentifier. Used to identify an eNodeB uniquely within a Public Land Mobile Network (PLMN). The eNB-ID can have either 20 bits or 28 bits. It is also comprised within the Global eNB-ID, which uniquely identi- fies an eNodeB globally.

What is the difference between cell ID and physical cell ID?

Physical Cell ID is mainly used by UE to decode physical layer data being transmitted by eNodeB. Cell ID in SIB1 is designed for eNodeB management within the core network, but this one is also used for UE to identify a specific cell in terms of RRC/NAS layer processing.

How do I find my LAC and cell ID?

Finding location using MCC, MNC, LAC, and Cell ID

  1. MCC – Mobile Country Code.
  2. MNC – Mobile Network Code.
  3. LAC – Location Area Code; a 16 bit number thereby allowing 65536 location areas within one GSM PLMN.
  4. more info is available here on Wikipedia, Location Area Identity.

What is the difference between cell ID and physical cell ID in LTE?

How can I track a cell phone ID?

Type in *#*#4636#*#* into the dialer and that might be what you’re looking for.

What is ECGI in LTE?

ECGI : It indicates the E-UTRAN cell global identifier. MCC: It indicates the country code of the mobile subscriber. MNC: Its indicates the code of network used by the mobile subscriber. Cell Identity: It is of 28 bits. The former 20 bits indicate the eNodeB ID, and the latter 8 bits indicate the cell ID.

How many Pcids are possible in 5G?

How 5G PCI is calculated? So PCI values will vary from 0 to 1007. 5GNR supports 1008 unique PCIs .
