Evolution of mobile phones, to an early
smartphone
A
mobile phone is a portable
telephone that can make and receive
calls over a radio frequency carrier while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a
mobile phone operator, which provides access to the
public switched telephone network (PSTN). Most modern mobile telephone services use a
cellular network architecture, and therefore mobile telephones are often also called
cellular telephones or
cell phones. In addition to
telephony, 2000s-era mobile phones support a variety of other
services, such as
text messaging,
MMS,
email,
Internet access, short-range wireless communications (
infrared,
Bluetooth), business applications, gaming, and
digital photography. Mobile phones which offer these and more general computing capabilities are referred to as
smartphones.
The first handheld mobile phone was demonstrated by
John F. Mitchell[1][2] and
Martin Cooper of
Motorola in 1973, using a handset weighing c. 4.4 lbs (2 kg).
[3] In 1983, the
DynaTAC 8000x was the first commercially available handheld mobile phone. From 1983 to 2014, worldwide mobile phone subscriptions grew to over seven billion, penetrating 100% of the global population and reaching even the
bottom of the economic pyramid.
[4] In 2016, the top mobile phone manufacturers were
Samsung,
Apple and
Huawei.
