A '''mobile network''' or '''cellular network''' is a [[communication network]] where the connection between end nodes are [[wireless]]. The network is spread over land areas called "cells", each served by at least one location [[transceiver]] (usually three [[cell site]]s or [[base transceiver station]]s). These base stations provide the cell with the network coverage which can be used for [[transmission]] of communications and similar.<ref name=Zander>{{cite book|author1=Guowang Miao|author2=Jens Zander|author3=Ki Won Sung|author4=Ben Slimane|title=Fundamentals of Mobile Data Networks|publisher=[[Cambridge University Press]]|isbn=978-1107143210|year=2016|author1-link=Guowang Miao}}</ref>

When joined together, these cells allow for radio signals over a wide area on the world. This enables a few portable transceivers (e.g., [[mobile phone]]s, [[tablet computer|tablets]] and [[laptop]]s with [[mobile broadband modem]]s, [[pager]]s, etc.) to communicate with each other and with still transceivers and telephones anywhere in the network, using base stations, even if some of the transceivers are moving through more than one cell during transmission.

Mobile networks offer a number of good features:<ref name=Zander/>
* Larger than a single large transmitter, since the same frequency can be used for multiple links if they are in different cells
* Mobile devices like phones use less power than with a single transmitter or satellite since the cell towers are closer to them<ref name=":0" />
* Larger area covered than a single on land transmitter, since more cell towers can be added later and are not limited by the horizon

Larger telecommunications companies have released voice and data mobile networks over most of the land area of Earth that has people on.  This allows mobile phones and [[mobile computing]] devices to be connected to the [[public switched telephone network]] and public [[Internet access]].  Private mobile networks can be used for research<ref>{{cite web|author=Tom Simonite |url=http://www.technologyreview.com/view/510341/googles-private-cell-phone-network/ |title=Google's Private Cell Phone Network Could Be a Threat to Cellular Carriers &#124; MIT Technology Review |publisher=Technologyreview.com |date=24 January 2013 |access-date=23 November 2013}}</ref> or for large organizations, such as helping with public safety agencies or a taxi company.<ref name=":0">{{cite web|url=http://www.privatemobilenetworks.com/ |title=Be Mobile, Stay Connected &#124; PMN |publisher=Privatemobilenetworks.com |access-date=23 November 2013}}</ref>
