History
of the Mobile Phone
Bluetooth
lIn 1970 Amos Joel
of Bell Labs invented "call handoff" that allowed a mobile phone user
to travel through several cells during the same conversation
lMartin Cooper of
Motorola is widely considered to be the inventor of the first practical mobile
phone for handheld use in a non-vehicle setting
lUsing a modern, if
somewhat heavy portable handset, Cooper made the first call on a handheld
mobile phone on April 3, 1973
lFully automatic
cellular networks were first introduced in the early to mid-1980s (the 1G
generation)
lUntil the late
1980s, most mobile phones were too large to be carried in a jacket pocket, so
they were usually permanently installed in vehicles as car phones
SMS
(Short Message System)
lSMS was being
considered as a feature for mobile phones as early as 1985
lThe first
commercial text message wasn't sent until 1992 from a personal computer to a
mobile phone
lThe first phone to
phone SMS was claimed to have been sent by Riku Pihkonen, an engineering student at Nokia, in 1993.
lInitial growth was
slow, with customers in 1995 sending on average only 0.4 messages per GSM
customer per month
lA whole new
alphabet emerged because SMS messages took a long time to enter and were quite
abrupt as people attempted to say as much as possible with as few keystrokes.
Abbreviations such as 'C U L8er' for 'See you later' sprung up for time saving
and trendiness
Ringtones
Camera
Phone
lIt all more or less
started with the famous 'Nokia Tune', which is a 13 note rendering of Francisco
Tarrega's masterpiece, Gran Vals. Tarrega was a 19th-century
Spanish musician.
lAround this time
all ringtones were monoponic, meaning they
could only play one note at a time.
lOne of the first
commercial ringtone service available was the finnish operator, Radiolinja´s "jukebox" service in 1999.
lThe year 2002 is a
major milestone in ringtone history. Nokia and other phone companies adopted
the MIDI standard that enabled richer and more realistic polyphonic sounds,
which is multiple notes being played at one time.
lModern mobile
phones can play MP3 files and have higher quality ringtones than ever before.
lA camera phone is a
mobile phone which has a camera built-in and allows the user to share pictures
and video with anyone instantly.
lThe first complete
camera phone was built by Philippe Kahn in 1997. The first commercial camera
phone complete with infrastructure was the J-SH04, made by Sharp Corporation
with the Sha-Mail (Picture-Mail in Japanese) infrastructure
and marketed by J-Phone in Japan. In
North America, the first camera phone was manufactured by Sanyo and launched by
Sprint with the PictureMail infrastructure.
Camera phones have become widely used because
they are cheap, convenient, and portable, and are now a staple of the majority
of cell phones.Bluetooth
l1998 The Bluetooth
Special Interest Group (SIG) is formed and officially adopts the project name
“Bluetooth” as the name of the technology
l1999 The Bluetooth
1.0 is released
l2000 The first
Bluetooth consumer product hits the market - a Bluetooth headset and phone
adapter from Ericsson
lBluetooth wireless
technology is a short-range communications technology intended to replace the
cables connecting portable and/or fixed devices
lBluetooth enables
user to have an affordable and easy way to have a hands free experience when
using mobile phones.
