Cellular lattice tower A cell tower in Peristeri, Greece. 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.
The tallest structure in the world is the Burj Khalifa skyscraper at 828 m (2,717 ft). Listed are guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electricity transmission towers, and bridge support towers. This list is organized by absolute height.

In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 ...
The Tokyo Skytree in Tokyo, Japan has been the tallest tower since 2012.. This list includes extant structures that fulfill the engineering definition of a tower: "a tall human structure, always taller than it is wide, for public or regular operational access by humans, but not for living in or office work, and which is self-supporting or free-standing, meaning no guy-wires for support."
This is a part of the list of tallest structures in the world, past and present of any type.. This list includes quite a lot of masts. A mast is a man-made support structure, commonly used on sailing ships as support for sails, or on land as radio masts and towers used to support telecommunication equipment such as radio antennas ("aerials" in the UK).
A guyed mast is cheaper to build than a self-supporting tower of equal height. A guyed mast needs additional land to accommodate the guys, and is thus best suited to rural locations where land is relatively cheap. An unguyed tower will fit into a much smaller plot. A steel lattice tower is cheaper to build than a concrete tower of equal height.
The increased capacity in a cellular network, compared with a network with a single transmitter, comes from the mobile communication switching system developed by Amos Joel of Bell Labs [5] that permitted multiple callers in a given area to use the same frequency by switching calls to the nearest available cellular tower having that frequency ...
This led to the split of definitions, with the Sears Tower claiming the lead in this and the height-to-roof (now highest occupied floor) categories, and with the Petronas claiming the lead in the architectural height category. If the World Trade Center towers were still standing, the North (1,368 feet (417 m)) and South Towers (1,362 feet (415. ...
