Cellular network

cellular networkcellularmobile network
A cell site or cell tower is a cellular-enabled mobile device site where antennae 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.
The network is distributed over land areas called cells, each served by at least one fixed-location transceiver, but more normally three cell sites or base transceiver stations.

GPS navigation device

GPSIntegratedGPS receiver
The raised structure typically supports antennae and one or more sets of transmitter/receivers transceivers, digital signal processors, control electronics, a GPS receiver for timing (for CDMA2000/IS-95 or GSM systems), primary and backup electrical power sources, and sheltering. Cellular geolocation is less precise than by GPS, but it is available to devices that do not have GPS receivers and where the GPS is not available.
The GPS capability of smartphones may use assisted GPS (A-GPS) technology, which can use the base station or cell towers to provide a faster Time to First Fix (TTFF), especially when GPS signals are poor or unavailable.

CDMA2000

The raised structure typically supports antennae and one or more sets of transmitter/receivers transceivers, digital signal processors, control electronics, a GPS receiver for timing (for CDMA2000/IS-95 or GSM systems), primary and backup electrical power sources, and sheltering.
CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites.

Backhaul (telecommunications)

backhaulbackhaul networkback-haul
A generator may be included for use where network electrical power is not available, and the system may have a wireless backhaul link allowing use where a wired link is not available.
Cell phones communicating with a single cell tower constitute a local subnetwork; the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the Internet service provider's network (via a point of presence).

Handover

The most basic form of handover is when a phone call in progress is redirected from its current cell (called source) to a new cell (called target).

Geolocation

Cellular geolocation is less precise than by GPS, but it is available to devices that do not have GPS receivers and where the GPS is not available.
When satellite navigation (such as GPS) signals are unavailable, geolocation applications can use information from cell towers to triangulate the approximate position, a method that is not as accurate as GPS but has greatly improved in recent years.

Base station

base stationbase stationsradio base station
In Global System for Mobile Communications (GSM) networks, the correct term is Base Transceiver Station (BTS), and colloquial synonyms are "mobile phone mast" or "base station".
Fuel cell backup power systems are added to critical base stations or cell sites to provide emergency power.

Radio masts and towers

radio towermastbroadcast tower
A cell site or cell tower is a cellular-enabled mobile device site where antennae 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.
Many people view bare cellphone towers as ugly and an intrusion into their neighbourhoods.

In re Application of the United States for Historical Cell Site Data

2013), was a case in which the United States Court of Appeals for the Fifth Circuit held that the government can access cell site records without a warrant.

Telecommunications lease

monopalm
Nicknames include "monopalm" for a monopole disguised as a palm tree or "Pseudopinus telephoneyensis" for a mast disguised as a pine tree.
Similar to other real estate leases, a telecommunications lease is put in place as an agreement to lease space on the landowner’s property for a telecommunications site or cellular tower for a specified length of time.

Antenna (radio)

A cell site or cell tower is a cellular-enabled mobile device site where antennae 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.
Used as base station antennas for land mobile radio systems such as police, fire, ambulance, and taxi dispatchers, and sector antennas for cellular base stations.

Assisted GPS

Assisted GPS uses both satellite and cell phone signals.

Radio

radioradio communicationradio communications
Cellular networks are designed to support many conversations with a limited number of radio channels (slices of radio frequency spectrum necessary to make one conversation) that are licensed to an operator of a cellular service.
Mobile phones transmit to a local cell site (transmitter/receiver) that ultimately connects to the public switched telephone network (PSTN) through an optic fiber or microwave radio and other network elements.

Base station subsystem

The base station controller (a central computer that specializes in making phone connections) and the intelligence of the cellphone keeps track of and allows the phone to switch from one mast to the next during conversation.

Mobile cell sites

COWcells-on-wheelscell on wheels
Although cell antennas are normally attached to permanent structures, carriers also maintain fleets of vehicles, called cells-on-wheels (COWs), that serve as temporary cell sites.
For instance, a carrier may have approved the placement of a cell site for coverage reasons, but the remaining budget is inadequate to fund the construction for a fiscal quarter or even longer.

Telecom infrastructure sharing

Basically a cell site consists of electronic (active) and non-electronic infrastructure.

A full cell site has a cabinet, an antenna mast and actual antenna.

Wind power

Renewable sources, such as solar power and wind power may be available where cell sites are placed.
Regarding tourism, query responders consider power pylons, cell phone towers, quarries and plantations more negatively than wind farms.

Femtocell

In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business.

Dirtbox (cell phone)

A dirtbox (or DRT box) is a cell site simulator, or a phone device mimicking a cell phone tower.

Municipal wireless network

In 2007, some companies with existing cell sites offered high-speed wireless services where the laptop owner purchased a PC card or adapter based on EV-DO cellular data receivers or WiMAX rather than 802.11b/g.

Mobile phone tracking

Localization may occur either via multilateration of radio signals between (several) cell towers of the network and the phone, or simply via GPS.

Satellite phone

A satellite telephone, satellite phone, or satphone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites.
