‘mobile network’

*a cellular network is a ‘communication network’ where the last link is ‘wireless’*
.
(the ‘network’ is distributed over land areas called ‘cells’, each served by at least 1 ‘fixed-location transceiver’, but more normally 3 ‘cell sites’ or ‘base transceiver stations’)
(these ‘base stations’ provide the ‘cell’ with the ‘network coverage’ which can be used for transmission of ‘voice’, ‘data’, and others)
(a ‘cell’ typically uses a different set of ‘frequencies’ from neighboring ‘cells’, to avoid interference and provide guaranteed service quality within each ‘cell’)
(when joined together these ‘cells’ provide radio coverage over a wide geographic area)
(this enables a large number of ‘portable transceivers’ (e.g., ‘mobile phones’, ‘tablets’, and ‘laptops’ equipped with ‘mobile broadband modems’, ‘pagers’, et cetera) to communicate with each other and with fixed ‘transceivers’ and ‘telephones’ anywhere in the ‘network’, via ‘base stations’, even if some of the ‘transceivers’ are moving through more than 1 ‘cell’ during ‘transmission’)
(‘cellular networks’ offer a number of desirable features:)
(more capacity than a single large ‘transmitter’, since the same ‘frequency’ can be used for multiple links as long as they are in different ‘cells’)
(‘mobile devices’ use less ‘power’ than with a single ‘transmitter’ or ‘satellite’ since the ‘cell towers’ are closer)
(‘cell towers’ also have a larger ‘coverage area’ than a single ‘terrestrial transmitter’, since additional ‘cell towers’ can be added indefinitely and are not limited by the ‘horizon’)
(major ‘telecommunications providers’ have deployed ‘voice’ and ‘data’ cellular networks over most of the inhabited land area of the ‘earth’)
(this allows ‘mobile phones’ and ‘mobile computing devices’ to be connected to the ‘public switched telephone network’ and ‘public internet’)
(‘private cellular networks’ can be used for ‘research’ or for large ‘organizations’ and ‘fleets’, such as “‘dispatch for ‘local public safety agencies’ or a ‘taxicab company'”)
