The mobile phone or cellular
1
phone is a long-range, portable electronic device used for mobile
communication. In addition to the standard voice function of a telephone, current mobile phones can
support many additional services such as SMS for text messaging, email, Bluetooth, packet switching for
access to the Internet, and MMS for sending and receiving photos and video.
Radiophones have a long and varied history. In 1945, the zero generation (0G) of mobile telephones
was introduced. Due to their low establishment costs and rapid deployment, mobile phone networks have
since spread rapidly throughout the world, outstripping
2
the growth of fixed telephony. 0G mobile
telephones, such as Mobile Telephone Service, were not officially categorized as mobile phones, since
they did not support the automatic change of channel frequency during calls, which allows the user to
move from one cell to another cell, a feature called "handover"

Motorola is widely considered to be the inventor of the first practical mobile phone for handheld
4
use in a non-vehicle setting. Using a modern, if somewhat heavy portable handset, Motorola manager
Martin Cooper made the first call on a handheld mobile phone on April 3, 1973.
The first commercial cellular network was launched in Japan by Nippon* Telegraph and Telephone
Corporation (NTT) in 1979. Fully automatic cellular networks were first introduced in the early to mid
1980s (the 1G generation) with the Nordic** Mobile Telephone (NMT) system in 1981. This was
followed by a boom in mobile telephone usage, particularly in Northern Europe.
The first "modern" network technology on digital 2G (second generation) cellular technology was
launched by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard. A decade
later, the first commercial launch of 3G (Third Generation) was again in Japan by NTT on the WCDMA
standard.
Until the early 1990s, most mobile phones were too large to be carried in a jacket pocket, so they
were typically installed in vehicles as car phones. With the miniaturization of digital components, mobile
phones have become increasingly handy over the years.
