5. Definitions
• A mobile phone, cell phone or hand phone- is an
electronic device used to make mobile telephone
calls across a wide geographic area, served by many
public cells, allowing the user to be mobile. These
communication devices connect to a wireless
communications network through radio waves or
satellite transmissions.
-A portable telephone that connects with the
telephone network using radio waves

6. • GSM-Global System for Mobile, an international standard for
mobile phones
• IP- Internet Protocol address; a sequence of numbers used to identify a
particular computer or domain name on the Internet
• Wi-Fi- Wireless Fidelity, A local area network that uses high frequency
radio signals to transmit and receive data over distances of a few hundred
feet; uses ethernet protocol
• GPS- Global Positioning System. A navigational system involving satellites
and computers that can determine the latitude and longitude of a receiver
on Earth by computing the time difference for signals from different
satellites to reach the receiver
• SIM Card-Subscriber Identity Module a small microchip.

7. Telephones and Radiophones

8. HISTORY
• 1950- Radiophones have a long and varied history going back to
Reginald Fessenden’s invention and shore-to-ship demonstration of
radio telephony, through the World war II with military use of radio
telephony links and civil services.
• On June 17, 1946- The first mobile telephone call made from a car
occurred St. Louis, Missouri USA using the Bell System’s Mobile
Telephone Services.
Disadvantages: the system was impractical from what is
considered a portable handset today. The equipment weighed 80
pounds (36 kg), and the AT&T service, basically a massive party
line, it is expensive too.

9. Commercial Cellphones

10. Commercial Phones
• On April 3, 1973- Martin Cooper
made the first call on a handheld
mobile phone to his rival, Dr. Joel
S. Engel of Bell Labs .
• Martin Cooper, is a Motorola
researcher and executive is
considered to be 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.

11. Evolution of Cellphones

12. First Generation: Analog Cellular Networks
(1G)
• The technology in these early networks was pushed
to the limit to accommodate increasing usage. The
base stations and the mobile phones utilized variable
transmission power, which allowed range and cell
size to vary. As the system expanded and neared
capacity, the ability to reduce transmission power
allowed new cells to be added, resulting in
more, smaller cells and thus more capacity.

13. • In 1979- The first commercially automated cellular network
(the 1G) was launched in Japan by NTT initially in the
metropolitan area of Tokyo.
Japan 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.
• In 1983- The first 1G network launched in the USA was
Chicago-based Ameritech using the Motorola DynaTAC
mobile phone.

15. Second Generation: Digital Mobile
Communication (2G)
• These differed from the previous generation by using
digital instead of analog transmission, and also fast
out-of-band phone-to-network signaling. The rise in
mobile phone usage as a result of 2G was explosive
and this era also saw the advent of prepaid mobile
phones.

16. • In the 1990s- the 'second generation' (2G) mobile phone systems
emerged, primarily using the GSM standard.
• In 1991- The first "modern" network technology on digital 2G
(second generation) cellular technology was launched by Radiolinja
in Finland on the GSM standard, which also marked the
introduction of competition in mobile telecoms .
• The second generation introduced a new variant of
communication called SMS or text messaging.

17. • 3 December 1992- The first machine-generated SMS message was
sent in the UK
• in 1993 - the first person-to-person SMS sent in Finland.
• In the late 1990s- The advent of prepaid services soon made SMS
the communication method of choice amongst the young, a trend
which spread across all ages.
• 2G introduced the ability to access media content on mobile
phones.

18. • In 1998- the first downloadable content sold to mobile phones was
the ring tone, launched by Finland's Radiolinja (now Elisa).
• In 1999- The first commercial payment system to mimic banks and
credit cards was launched in the Philippines and simultaneously by
mobile operators Globe and Smart.
• In 1999- The first full internet service on mobile phones was
introduced by NTT DoCoMo in Japan.
• In 2000- Advertising on the mobile phone first appeared in Finland
when a free daily SMS news headline service.

20. Third generation: High speed IP data networks
and
Wideband mobile communication
• The main technological difference that distinguishes
3G technology from 2G technology is the use of
packet switching rather than circuit switching for
data transmission.

21. • May 2001- The first pre-commercial trial network with 3G was
launched by NTT DoCoMo in Japan in the Tokyo region.
• October 1, 2001- NTT DoCoMo launched the first commercial 3G
network
• In 2002 -the first 3G networks on the rival CDMA2000 1xEV-DO
technology were launched by SK Telecom and KTF in South
Korea, and Monet in the USA.
• In the mid 2000s -an evolution of 3G technology begun to be
implemented, namely High-Speed Downlink packet Access(HSDPA).

23. Fourth generation: All-IP networks
• By 2009-it had become clear that, at some point, 3G networks
would be overwhelmed by the growth of bandwidth-intensive
applications like streaming media. The first two commercially
available technologies billed as 4G were the WiMAX standard
offered in the U.S. by Sprint and the LTE standard, first offered in
Scandinavia by TealiaSonera.
• One of the main ways in which 4G differed technologically from 3G
was in its elimination of circuit switching, instead employing an
all-IP network. Thus, 4G ushered in a treatment of voice calls just
like any other type of streaming audio media, utilizing packet
switching over internet, LAN or WAN networks.

25. The mobile phone is often called the
• Fourth Screen: if counting cinema, TV and PC
screens as the first three
• Third Screen: counting only TV and PC screens.
• It is also called the Seventh of the Mass Media: with
Print, Recordings, Cinema, Radio, TV and Internet the
first six.

27. Features
Common components found on all phones are:
• A battery, typically rechargeable, providing the power source for
the phone functions
• An input mechanism to allow the user to interact with the phone.
Like the keypad, but touch screens are also found in some high-end
smart phones.
• Basic mobile phone services to allow users to make calls and send
text messages.
• All GSM phones use a SIM card to allow an account to be swapped
among devices.

35. Media
• In 1998- one of the first examples of selling media content
through the mobile phone was the sale of ringtones by
Radiolinja in Finland. Soon afterwards, other media content
appeared such as news, videogames, jokes, horoscopes, TV
content and advertising.
• In 2006- the total value of mobile-phone-paid media content
exceeded Internet-paid media content and was worth 31
billion dollars.
• In 2007- The value of music on phones was worth 9.3 billion
dollars and gaming was worth over 5 billion dollars.

38. Restrictions and Dangers
• While Driving
• In school
• In work
• While walking
• Privacy

40. --A study by Motorola found that one in ten
cell phone subscribers have a second phone
that often is kept secret from other family
members. These phones may be used to
engage in activities including extramarital
affairs or clandestine business dealings.

41. HEALTH EFFECTS
• On 31st May 2011, the World Health Organization confirmed
that mobile phone radiation has a "carcinogenic hazard" and
"possibly carcinogenic to humans" after a team of scientists
reviewed peer-review studies on cell phone safety.
• gliomas brain cancer in the highest category of heavy users
reported average: 30 minutes per day over a 10‐year period.
• Mobile phones use electromagnetic radiation in the
microwave range, which some believe may be harmful to
human health.
• 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 staff.

42. Trending topics
