service to small adjacent areas from localised stations
A general descriptive term for a system of providing two-way radio coverage to a battery-powered handset that resembles and functions like a landline telephone. A cellular phone is, in fact, nothing more than a radio. There is no "cellular energy" or "cellular frequency." A cellular mobile communications system uses a combination of radio transmission and conventional telephone switching to permit telephone communication among mobile users within a specified area (or between a mobile unit and a conventional landline telephone). Large geographical areas are segmented into many smaller areas, or "cells." Each cell has its own radio transmitters and receivers and a single controller interconnected with the public switched telephone network. PCS phones also use cellular technology.
A term that refers to the radio antenna network of "cells" that allow users of mobile telephones to communicate with no physical connection.

The name given to the original concept of dividing a large geographic area into smaller coverage areas called cells. Each cell handles calls on different channels and communicates with the central processing unit, called a switch, or terminal, to facilitate the handing-off of calls from one cell to another as a user moves through the system. Cellular Telephony is currently used in hundreds of countries worldwide and boasts more than 200 million subscribers.
technology that sends analog or digital transmissions from transmitters that have areas of coverage called cells. Cellular is sometimes used to refer to all wireless phones, regardless of the technology they use.
The most familiar type of wireless communication. It is called "cellular" because each service area was divided into cells or cell stations.
characterized by or divided into or containing cells or compartments (the smallest organizational or structural unit of an organism or organization); "the cellular construction of a beehive"; "any effective opposition to a totalitarian regime must be secretive and cellular"; "a cellular phone uses a network of shortrange transmitters located in overlapping cells"
Technology that sends analogue or digital transmissions from transmitters that have areas of coverage called cells. As a user of a cellular phone moves between transmitters from one cell to another, the user's call travels from transmitter to transmitter uninterrupted.
A means of communication via radio waves. Specific spectrum allocation is provided to geographic areas called cells which, in turn, are interconnected to allow communication from one point to another.
A wireless communications network architecture which employs "cells" or modular coverage areas, typically serviced by a “cell site”, and usually provides hand-off capability between cells for roaming devices. (See also hand-off and roaming)
A mobile telephone system that uses radio waves to provide coverage in certain geographic areas or "cells". These cells are usually adjacent to each other and combine to offer continuous coverage over wide areas such as entire cities or highway corridors.
A radio phone system in which a network of transmitters links the mobile user to the public phone system. Each transmitter covers users in its own ‘cell’.
A cell is the name given to the area of land covered by the signal from a particular radio antenna. Orange is a cellular phone network that uses the latest digital technology.
Refers to a communication system that divides geographic regions into sections called cells. The purpose of this division is to make the most use of the limited number of transmission frequencies.
In wireless communications, cellular basically refers to the structure of the wireless transmission networks which are comprised of cells or transmission sites. Cellular is also the name of the wireless telephone system originally developed by Bell Laboratories that used low-powered analog radio equipment to transmit within cells. The terms "cellular phone" or "cell phone" are used interchangeably to refer to wireless phones. Within the wireless industry, cellular is also used to refer to non- PCS products and services.
It refers to the way cities and counties are divided into basic geographic unit, called cells.
Term used to describe mobile phone communications. Each transmitter covers an area known as a "cell"
A wireless telephone technology that makes use of a range of radio frequencies to transmit calls. Cellular modems have also been invented to allow for computer connections via cellular phones.
A radio telephone system in which a network of transmitters link the user's telephone to the network. Each individual transmitter provides signals to a geographic area called a cell (hence the term cellular radio). As the user moves between cells the call is automatically handed over from one cell to another.
A mobile telephone service provided by a network of base stations, each of which covers one geographic cell within the total cellular system service area.
Circuit-switched voice telephone communications via cellular radio channels. The service area is divided into many cells and in each there is a base station handling the communications in that particular cell.
Analog or digital communications that provide a consumer with a wireless connection from the mobile device to a relatively nearby transmitter (base station). The transmitterâ€(tm)s coverage area is called a cell. See Also: Base Station
Cellular refers to an analog or digital mobile phone system operating in the 800MHz band.
A wireless phone system that uses a grid of cells, each managed by a base station. Often refers to such systems that operate in our around the 800 - 1000 MHz band.
A radio phone system in which a network of transmitters (phone masts) links mobile phone users to the public phone network. Each transmitter covers users in its own zone or "cell". This lies at the heart of mobile telephony. Hence the term "Cellular Telephones".
The type of wireless communication that is most familiar to mobile phones users. Called 'cellular' because the system uses many base stations to divide a service area into multiple 'cells'. Cellular calls are transferred from base station to base station as a user travels from cell to cell.
The colloquialism for Cellular Mobile Telephone Service (or System), also known as CMTS.
Refers to communications systems, especially the Advance Mobile Phone Service (AMPS), that divide a geographic region into sections, called cells. The purpose of this division is to make the most use out of a limited number of transmission frequencies. Each connection, or conversation, requires its own dedicated frequency, and the total number of available frequencies is about 1,000. To support more than 1,000 simultaneous conversations, cellular systems allocate a set number of frequencies for each cell. Two cells can use the same frequency for different conversations so long as the cells are not adjacent to each other.
Cellular service is a form of wireless telephone that uses FM radio waves to transmit conversations. Cellular calls are transmitted using either digital or analog technology. Through analog transmission, your voice is actually carried on the airwaves. Digital transmission transforms the human voice into computer language, providing greater system capacity.
General name for analog and digital networks that divide large areas into smaller coverage areas called cells. As a user moves from cell to cell their connection is theoretically handed off without interruption.
Wireless telephone service which is interconnected to the Public Switched Telephone Network (PSTN), the regular telephone network.
A wireless personal communications system that makes use of base station controllers. These controllers use multidirectional antennas to create spatial cells for frequency reuse.
Communications systems that use a network of transmitters to reach different locations are said to be cellular—for example, cellular phones work by connecting to the closest broadcast tower at any given time. A company such as AT&T Wireless has broadcasting towers all over the country, and the zones they cover are the individual 'cells' in their service map.
Analog or digital communications in which a subscriber has a wireless connection from a mobile handset to a relatively nearby transmitter. The transmitter's span of coverage is called a cell. Generally, cellular telephone service is available in urban areas and along major highways. As the cellular telephone user moves from one cell or area of coverage to another, the telephone is effectively passed on to the local cell transmitter. A newer service and alternative to cellular is PCS. See also PCS and roaming.
A general term used to describe any one of several mobile wireless telephony applications which divide up a given geographical area into a smaller sub regions called cells.
A wireless telephone network that connects radio frequencies from a mobile phone to a system of multiple cell sites, each consisting of an antenna and a base station, to a mobile telephone switching office, and ultimately to the public wireline telephone system. Called 'cellular' because the system uses many base stations to divide a service area into multiple 'cells'. Cellular calls are transferred from base station to base station as a user travels from cell to cell.
Related to using cells for radio transmission.
A communication service in which voice or data is transmitted by radio frequencies. The service area is divided into cells, each served by a transmitter. The cells are connected to a mobile switching exchange, which is connected to the worldwide telephone network.
