Cell Global Identity (CGI) is a globally unique identifier for a Base Transceiver Station in mobile phone networks. [1] It consists of four parts: Mobile Country Code (MCC), Mobile Network Code (MNC), Location Area Code (LAC) and Cell Identification (CI). It is an integral part of 3GPP specifications for mobile networks, for example, for ...
The unique location area identities of the cell towers can be collected by devices that utilize the wireless network provided by those cell towers. [3] This data is primarily contributed by smartphone users who have installed apps, such as OpenCelliD [4] or OpenCelliD Client, [5] and commercial tracking devices such as blackboxes, but also by wholesale data donation by corporations.
A GSM Cell ID (CID) is a generally unique number used to identify each base transceiver station (BTS) or sector of a BTS within a location area code (LAC) if not within a GSM network. In some cases the first or last digit of CID represents cells' Sector ID: values 1, 2, and 3 are used to identify sectors of bisector or trisector antennas.
Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply using GNSS. To locate a mobile phone using multilateration ...
The StingRay is an IMSI-catcher with both passive (digital analyzer) and active (cell-site simulator) capabilities. When operating in active mode, the device mimics a wireless carrier cell tower in order to force all nearby mobile phones and other cellular data devices to connect to it. [9][10][11] The StingRay family of devices can be mounted ...

Cellular lattice tower A cell tower in the bush in Africa. A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network.
