Fourth generation (4G)
4th generation, also known as Beyond 3G, aims to provide broadband wireless access with nominal data rates of 100 M
bit/s to fast moving devices, and 1 G bit/s to stationary devices defined by
the ITU-R
4G systems may be based on the 3GPP LTE (Long Term Evolution) cellular standard,
offering peak bit rates of 326.4 Mbit/s. It may perhaps also be based on WiMax or Flash-OFDM wireless metropolitan area network
technologies that promise broadband wireless access with speeds that reaches 233 Mbit/s
for mobile users. The radio interface in these systems is based on all-IP packet switching, MIMO diversity, multi-carrier modulation schemes, Dynamic Channel Assignment (DCA) and channel-dependent scheduling. A 4G system
should be a complete replacement for current network infrastructure and is
expected to be able to provide a comprehensive and secure IP solution where
voice, data, and streamed multimedia can be given to users on a "Anytime, Anywhere"
basis, and at much higher data rates than previous generations.
In March 2011, KT from
South Korea
announced that they has expanded its high-speed wireless broadband network by 4G WiBro cover 85 percent of the population. It
is the largest broadband network covered in the world, followed by Japan and US
with 70 percent and 36 percent respectively.
In early 2011, 4G mobile phones
were released by Motorola, HTC and Samsung.
Health effects
The effect mobile phone
radiation has on human health is the subject of recent interest and study, as a
result of the enormous increase in mobile phone usage throughout the world. Mobile phones use electromagnetic radiation in the microwave range, which some believe may be
harmful to human health. A large body of research exists, both epidemiological and experimental, in non-human
animals and in humans,
of which the majority shows no definite causative relationship between exposure
to mobile phones and harmful biological effects in humans. This is often
paraphrased simply as the balance of evidence showing no harm to humans from
mobile phones, although a significant number of individual studies do suggest
such a relationship, or are inconclusive. Other digital wireless systems, such as data
communication networks, produce similar radiation.
On 31 May 2011, the World Health Organization confirmed that mobile phone use may
represent a long-term health risk. classifying mobile phone radiation as a
"carcinogenic hazard" and "possibly carcinogenic to humans"
after a team of scientists reviewed peer-review studies on cell phone safety. One study of past cell phone use cited
in the report showed a "40% increased risk for gloms
(brain cancer) in the highest
category of heavy users (reported average: 30 minutes per day over a 10‐year
period). This is a reversal from
their prior position that cancer was unlikely to be caused by cellular phones
or their base stations and that reviews had found no convincing evidence for
other health effects. Certain countries, including France , have warned against the use
of cell phones especially by minors due to health risk uncertainties.
At least some recent studies
have found an association between cell phone use and certain kinds of brain and
salivary gland tumors. Lennart Hardell and other authors of a 2009
meta-analysis of 11 studies from peer-reviewed journals concluded that cell
phone usage for at least ten years “approximately doubles the risk of being
diagnosed with a brain tumor on the same ('ipsilateral') side of the head as
that preferred for cell phone use.
In addition, a mobile phone can spread infectious diseases by its frequent contact with hands.
One study came to the result that pathogenic bacteria are present on approximately 40% of
mobile phones belonging to patients in a hospital, and on approximately 20% of
mobile phones belonging to hospital staffSubscriber Identity Module or SIM Card,
GSM mobile phones require a small microchip called a Subscriber Identity Module or SIM Card, to function. The SIM card is
approximately the size of a small postage stamp and is usually placed
underneath the battery in the rear of the unit. The SIM securely stores the service-subscriber key (IMSI) used to identify a subscriber on
mobile telephony devices (such as mobile phones and computers). The SIM card
allows users to change phones by simply removing the SIM card from one mobile
phone and inserting it into another mobile phone or broadband telephony device.
A SIM card contains its unique
serial number, internationally unique number of the mobile user (IMSI), The
first SIM card was made in 1991 by Munich
smart card maker Giesecke & Devrient for the Finnish wireless network operator Radiolinja.
Giesecke & Devrient sold the first 300 SIM cards to Elisa (ex. Radiolinja).
First 2G (second generation) & 3G (third generation)
First 2G (second
generation) & 3G (third
generation)
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, which also marked the
introduction of competition in mobile telecoms when Radiolinja challenged
incumbent Telecom Finland (now part of TeliaSonera) who ran a 1G NMT network.
In 2001, the launch of 3G (Third
Generation) was again in Japan
by NTT DoCoMo on the WCDMA standard.
One of the newest 3G technologies to be
implemented is High-Speed
Downlink Packet Access (HSDPA).
It is an enhanced 3G (third generation) mobile telephony communications protocol in the high-speed packet access (HSPA) family, also coined 3.5G, 3G+
or turbo 3G, which allows networks based on Universal
Mobile Telecommunications System (UMTS)
to have higher data transfer speeds and capacity.
The first cellular/ mobile network
The first commercially
automated cellular network (the 1G)
was launched in Japan by NTT in
1979, initially in the metropolitan area of Tokyo . Within five years, the NTT network had
been expanded to cover the whole population of Japan and became the first
nationwide 1G network. In 1981, this was followed by the simultaneous launch of
the Nordic Mobile Telephone (NMT) system in Denmark , Finland ,
Norway and Sweden . NMT was the first mobile phone network
featuring international roaming.
The first 1G network launched in the USA was Chicago-based Ameritech in 1983 using the Motorola DynaTAC mobile phone. Several countries then
followed in the early-to-mid 1980s including the UK ,
Mexico and Canada .

the inventor of the mobile phone
Martin Cooper, a Motorola researcher and executive is considered
to bet the inventor of the first practical mobile phone for handheld use in a non-vehicle setting, after a
long race against Bell Labs for
the first portable mobile phone. Using a modern, if somewhat heavy portable
handset, Cooper made the first call on a handheld mobile phone on April 3, 1973
to his rival, Dr. Joel S. Engel of Bell
MTA
In 1956, the world’s first
partly automatic car phone system, Mobile System A
(MTA), was launched in Sweden .
MTA phones were composed of vacuum
tubes and relays, and had a weight of
40 kg. In 1962, a more modern version called Mobile System B (MTB) was launched, which was a push-button telephone, and which used transistors to enhance the telephone’s calling
capacity and improve its operational reliability, thereby reducing the weight
of the apparatus to 10 kg. In 1971, the MTD version was launched, opening for
several different brands of equipment and gaining commercial success.
The first mobile telephone call
The first mobile telephone call made from a car occurred in St. Louis ,
Missouri , USA on June 17, 1946, using the Bell System's Mobile Telephone Service. The
equipment weighed 80 pounds (36 kg), and the AT&T service, basically a massive party
line, cost US$30 per month (equal to $337.33 today) plus 30–40 cents per local
call, equal to $3.37 to $4.50 today.Wikipedia.com

A mobile phone (cellular phone, cell phone and a hand phone) is a device which
can make and receive telephone
calls over a radio link while moving around a wide geographic
area. It does so by connecting to a cellular
network provided by a mobile network operator. The calls are
to and from the public telephone
network which includes other
mobiles and fixed-line phones across the world. By contrast,
a cordless telephone is used only
within the short range of a single, private base station.
Modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access,
short-range wireless communications (infrared, Bluetooth), business applications,
gaming and photography. Mobile phones that offer these and more general computing
capabilities are referred to as smart
phones.
The first hand-held mobile phone was demonstrated by Dr Martin Cooper of Motorola in 1973, using a handset weighing 2
1/2 lbs (about 1 kg). In 1983,
the DynaTAC 8000x was the first to be commercially available.
In the twenty years from 1990 to 2010, worldwide mobile phone subscriptions
grew from 12.4 million to over 4.6 billion,
