1.INTRODUCTION

A mobile phone (also called mobile, cellular phone, cell phone or hand phone) is an

electronic device used forfull duplextwo-way radio telecommunications over a cellular networkofbase stations known as cell sites. Mobile phones differ from cordless telephones, which only

offertelephone service within limited range through a single base station attached to a fixed landline, for example within a home or an office.

A mobile phone allows its user to make and receive telephone calls to and from the publictelephone network, which includes other mobiles and fixed line phones across the world. It does

this by connecting to a cellular networkowned by a mobile network operator. A key feature of

the cellular network is that it enables seamless telephone calls even when the user is movingaround wide areas via a process known as handoffor handover.

In addition to being a telephone, modern mobile phones also support many additional services,

and accessories, such as SMS (or text) messages, email, Internet access, gaming, Bluetooth,

infrared, camera, MMS messaging, MP3 player, radio and GPS. Low-end mobile phones areoften referred to as feature phones, whereas high-end mobile phones that offer more advanced

computing ability are referred to as smart phones.

The first handheld cellular phone was demonstrated by Martin Cooper of Motorola in 1973,

using a handset weighing in at two kilos. In the year 1990, 12.4 million people worldwide hadcellular subscriptions. By the end of 2009, only 20 years later, the number of mobile cellular

subscriptions worldwide reached approximately 4.6 billion, 370 times the 1990 number,

penetrating the developing economies and reaching the bottom of the economic pyramid.

2.History

The first mobile telephone call made from a car occurred in St. Louis, Missouri, USA on

June 17, 1946, but the system was impractical from what is considered a portable handset today.

In 1960, the worlds first partly automatic car phone system, Mobile System A (MTA), waslaunched in Sweden. MTA phones were composed ofvacuum 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 in order to enhance the telephonescalling capacity and improve its operational reliability. In 1971 the MTD version was launched,

opening for several different brands of equipment and gaining commercial success.

Martin Cooper, a Motorola researcher and executive is considered the inventor of the first

practical mobile phone forhand-helduse in a non-vehicle setting, after a long race against BellLabs for the first portable mobile phone. Using a modern, if somewhat heavy portable handset,

Cooper made the first call on a hand-held mobile phone on April 3, 1973 to his rival, Dr. Joel S.

Engel ofBell Labs.

The first commercially automated cellular network (the 1G generation) 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 nation-wide 1Gnetwork. In 1981, this was followed by the simultaneous launch of theNordic Mobile Telephone

(NMT) system in Denmark, Finland, Norway and Sweden.[9] NMT was the first mobile phone

network featuring international roaming. The first 1G network launched in the USA was Chicagobased Ameritech in 1983 using the Motorola DynaTAC mobile phone. Several countries then

followed in the early 1980s including the UK, Mexico and Canada.

The first "modern" network technology on digital 2G (second generation) cellular technology

was launched by Radiolinja (now part ofElisa Group) in 1991 in Finland on the GSM standardwhich also marked the introduction of competition in mobile telecoms when Radiolinja

challenged incumbent Telecom Finland (now part ofTeliaSonera) who ran a 1G NMT network.

In 2001 the first commercial launch of 3G (Third Generation) was again in Japan by NTT

DoCoMo on the WCDMA standard.[10]

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 datatransfer speeds and capacity.

3. Handset feature

All mobile phones have a number of features in common, but manufacturers also try todifferentiate their own products by implementing additional functions to make them moreattractive to consumers. This has led to great innovation in mobile phone development over the

last twenty years.

The common components found on all phones are:

A rechargeable battery providing the power source for the phone functions

An input mechanism and display to allow the user to interact with the phone. The mostcommon input mechanism is a keypad, but touch screensare also found in some high-end

smart phones.

Basic mobile phone services to allow users to make calls and send text messages. All GSMphones use aSIM card to allow an account to be swapped among devices.

Some CDMA devices also have a similar card called anR-UIM.

Individual GSM, WCDMA, iDEN and some satellite phone devices are uniquelyidentified by an International Mobile Equipment Identity(IMEI) number.

Low-end mobile phones are often referred to as feature phones, and offer basic telephony, as

well as functions such as playing music and taking photos, and sometimes simple applications

based on generic managed platforms such as Java ME orBREW. Handsets with more advanced

computing ability through the use of native software applications became known as smart

phones. The first smart phone was the Nokia 9000 Communicator in 1996, which added PDAfunctionality to the basic mobile phone at the time. As miniaturization and increased processing

power of microchips has enabled ever more features to be added to phones, the concept of the

smart phone has evolved, and what was a high-end smart phone five years ago, is a standardphone today.

Several phone series have been introduced to address a given market segment, such as the RIM

BlackBerryfocusing on enterprise/corporate customer email needs; the SonyEricsson Walkman

series of music phones and Cyber shot series of camera phones; the Nokia N-series ofmultimedia phones, the Palm Pre theHTC Dreamand the Applei-Phone.

Other features that may be found on mobile phones include GPS navigation, music (MP3) and

video (MP4) playback, RDSradio receiver, alarms, memo recording, personal digital assistant

functions, ability to watch streaming video, video download, video calling, built-in cameras

(1.0+ Mpx) and camcorders (video recording), withautofocusand flash,ringtones, games, PTT,memory card reader (SD), USB (2.0), dual line support, infrared, Bluetooth (2.0) and Wi-Fi

connectivity,instant messaging, Internet e-mail andbrowsing and serving as a wireless modem.Nokia and theUniversity of Cambridge demonstrated abendable cell phone called theMorph.[11]

3.1 Software and application

The most commonly used data application on mobile phones is SMS text messaging. The firstSMS text message was sent from a computer to a mobile phone in 1992 in the UK, while the first

person-to-person SMS from phone to phone was sent in Finland in 1993.

Other non-SMS data services used on mobile phones include mobile music, downloadable logosand pictures, gaming, gambling, adult entertainment and advertising. The first downloadablemobile content was sold to a mobile phone in Finland in 1998, when Radiolinja (now Elisa)

introduced the downloadable ring tone service. In 1999 Japanese mobile operator, NTT DoCoMo

introduced its mobile internet service, i-Mode, which today is the world's largest mobile internet

service.

The first mobile news service, delivered via SMS, was launched in Finland in 2000. Mobile news

services are expanding with many organizations providing "on-demand" news services by SMS.

Some also provide "instant" news pushed out by SMS.

3.2 Power supply

Mobilephones generally obtain power from rechargeablebatteries. There are a variety of ways

used to charge cell phones, including USB, portable batteries, mains power (using an AC

adapter), cigarette lighters(using an adapter), or adynamo. In 2009, wireless charging became a

reality, and the first wireless charger was released for consumer use.

Standardization of Micro-USB connector for charging

Starting from 2010, many mobile phone manufacturers have agreed to use the Micro-USB

connector for charging their phones.[13] The mobile phone manufacturers who have agreed to this

standard include:

LG

Motorola

Nokia

Research In Motion

Samsung

Sony Ericsson

On 17 February 2009, the GSM Association announced that they had agreed on a standard

charger for mobile phones. The standard connector to be adopted by 17 manufacturers in theOpen Mobile Terminal Platform including Nokia, Motorola and Samsung is to be the micro-USB

connector(several media reports erroneously reported this as the mini-USB). The new chargers

will be much more efficient than existing chargers. Having a standard charger for all phones,means that manufacturers will no longer have to supply a charger with every new phone.

In addition, on 22 October 2009 the International Telecommunication Union (ITU) announced

that it had embraced micro-USB as the Universal Charger Solution its "energy-efficient one-

charger-fits-all new mobile phone solution", and added: "Based on the Micro-USB interface,UCS chargers will also include a 4-star or higher efficiency rating up to three times more

energy-efficient than an unrated charger."

Battery

Formerly, the most common form of mobile phone batteries were nickel metal-hydride, as they

have a low size and weight. Lithium ion batteries are sometimes used, as they are lighter and donot have the voltage depression that nickel metal-hydride batteries do. Many mobile phone

manufacturers have now switched to using lithium-polymer batteries as opposed to the older

Lithium-Ion, the main advantages of this being even lower weight and the possibility to make the

battery a shape other than strict cuboid.[18]

Mobile phone manufacturers have been experimentingwith alternative power sources, including solar cells and Coca Cola.[19]

GSM mobile phones require a small microchip called a Subscriber Identity Module orSIM 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 broadbandtelephony device.

A SIM card contains its unique serial number, internationally unique number of the mobile user

(IMSI), security authentication and ciphering information, temporary information related to the

local network, a list of the services the user has access to and two passwords (PIN for usual useand PUK for unlocking).

SIM cards are available in three standard sizes. The first is the size of a credit card (85.60 mm

53.98 mm x 0.76 mm). The newer, most popular miniature version has the same thickness but a

length of 25 mm and a width of 15 mm, and has one of its corners truncated (chamfered) to

prevent misinsertion. The newest incarnation known as the 3FF or micro-SIM has dimensions of15 mm 12 mm. Most cards of the two smaller sizes are supplied as a full-sized card with the

smaller card held in place by a few plastic links; it can easily be broken off to be used in a devicethat uses the smaller SIM.

The first SIM card was made in 1991 by Munich smart card makerGiesecke & Devrient for the

Finnish wireless network operatorRadiolinja. Giesecke & Devrient sold the first 300 SIM cards

to Elisa (ex. Radiolinja).

Those cell phones that do not use a SIM Card have the data programmed in to their memory.This data is accessed by using a special digit sequence to access the "NAM" as in "Name" or

number programming menu. From there, information can be added including: a new number forthe phone, new Service Provider numbers, new emergency numbers, new Authentication Key orA-Key code, and a Preferred Roaming List or PRL. However, to prevent the phone being

accidentally disabled or removed from the network, the Service Provider typically locks this data

with a Master Subsidiary Lock (MSL). The MSL also locks the device to a particular carrierwhen it is sold as a loss leader.

The MSL applies to the SIM only so once the contract has been completed the MSL still applies

to the SIM. The phone however, is also initially locked by the manufacturer into the Service

Providers MSL. This lock may be disabled so that the phone can use other Service ProvidersSIM cards. Most phones purchased outside the US are unlocked phones because there are

numerous Service Providers close to one another or have overlapping coverage. The cost to

unlock a phone varies but is usually very cheap and is sometimes provided by independent phonevendors.

A similar module called a Removable User Identity Module is present in some CDMA networks,

notably in China.

4.1 Media

In 1998, one of the first examples of selling media content through the mobile phone was the saleof ringtones by Radiolinja in Finland. Soon afterwards other media content appeared such as

news, videogames, jokes, horoscopes, TV content and advertising. Most early content for mobile

tended to be copies of legacy media, such as the banner advertisement or the TV news highlightvideo clip. Recently unique content for mobile has been emerging, from the ringing tones and

ring back tones in music to "mobisodes," video content that has been produced exclusively for

mobile phones.

In 2006 the total value of mobile phone paid media content exceeded internet paid media contentand was worth 31 Billion dollars (source Informa 2007). The value of music on phones was

worth 9.3 Billion dollars in 2007 and gaming was worth over 5 billion dollars in 2007.[22]

The advent of media on the mobile phone has also produced the opportunity to identify and track

Alpha Users or Hubs, the most influential members of any social community. AMF Venturesmeasured in 2007 the relative accuracy of three mass media, and found that audience measures

on mobile were nine times more accurate than on the internet and 90 times more accurate than on

TV.

The mobile phone is often called the Fourth Screen (if counting cinema, TV and PC screens as

the first three) or Third Screen (counting only TV and PC screens).[weasel words] It is also called the

Seventh of the Mass Media (with Print, Recordings, Cinema, Radio, TV and Internet the firstsix).

5. Usage

5.1 Examples

Mobile phones are used for a variety of purposes, including keeping in touch with family

members, conducting business, and having access to a telephone in the event of an emergency.

Some people carry more than one cell phone for different purposes, such as for business andpersonal use. Multiple SIM cards may also be used to take advantage of the benefits of different

calling plansa particular plan might provide cheaper local calls, long-distance calls,

international calls, or roaming. 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 beused to engage in activities including extramarital affairs or clandestine business dealings. [23]The

mobile phone has also been used in a variety of diverse contexts in society, for example:

Organizations that aid victims of domestic violence may offer a cell phone topotential victims without the abuser's knowledge. These devices are often oldphones that are donated and refurbished to meet the victim's emergencyneeds.[24]

Child predators have taken advantage of cell phones to secretlycommunicate with children without the knowledge of their parents orteachers.[25]

The advent of widespread text messaging has resulted in the cell phone

novel; the first literary genre to emerge from the cellular age via textmessaging to a website that collects the novels as a whole. [26] Paul Levinson,in Information on the Move (2004), says "...nowadays, a writer can write justabout as easily, anywhere, as a reader can read" and they are "not onlypersonal but portable".

Mobile telephony also facilitates activism and public journalism beingexplored by Reuters and Yahoo![27] and small independent news companiessuch asJasmine News in Sri Lanka.

5.2 Sharing

In some parts of the world, mobile phone sharing is common. It is prevalent in urban India, asfamilies and groups of friends often share one or more mobiles among their members. There are

obvious economic benefits, but often familial customs and traditional gender roles play a part.[28]

For example in Burkina Faso it is not uncommon for a village to have access to only one mobilephone. The phone is typically owned by a person who is not natively from the village, such as a

teacher or missionary, but it is the expected that other members of the village are allowed to use

the cell phone to make necessary calls.

5.3 Restrictions on usage

There exists a community that believes mobile phone use represents a long-term health risk,although this is currently disputed by the World Health Organization, with forthcoming mobile

phone usage recommendations in 2010. Certain countries, including France, have warned against

the use of cell phones especially by minors due to health risk uncertainties.[31] Groups ofscientists, such as the US based group Bioinitiative, argue that because mobile phone use isrecently introduced technology, long-term "proof" has been impossible and that use should be

restricted, or monitored closely, while the technology is still new.

5.3.1 Use while driving

Mobile phone use while driving is common but controversial. Being distracted while operating a

motor vehicle has been shown to increase the risk of accident. Because of this, many

jurisdictions prohibit the use of mobile phones while driving. Egypt, Israel, Japan, Portugal andSingapore ban both hand-held and hands-free use of a mobile phone whilst many other

countries including the UK, France, and many US states ban hand-held phone use only,

allowing hands-free use.

Due to the increasing complexity of mobile phones often more like mobile computers in theiravailable uses it has introduced additional difficulties for law enforcement officials in being

able to tell one usage from another as drivers use their devices. This is more apparent in those

countries who ban both hand-held and hands-free usage, rather those who have banned hand-helduse only, as officials cannot easily tell which function of the mobile phone is being used simply

by visually looking at the driver. This can mean that drivers may be stopped for using their

device illegally on a phone call, when in fact they were not; instead using the device for a legalpurpose such as the phones' incorporated controls for car stereo orsatnav usage either as part

of the cars' own device or directly on the mobile phone itself.Cases like these can often only be proved otherwise by a check of the mobile operators phone

call records to see if a call was taking place during the journey concerned. Although in manycountries the law enforcement official may have stopped the driver for a differing offence, for

example, for lack of due care and attention in relation to their driving.

5.3.2 Schools

Some schools limit or restrict the use of mobile phones. Schools set restrictions on the use of

mobile phones because of the use of cell phones for cheating on tests, harassment and bullying,

causing threats to the schools security, distractions to the students and facilitating gossip andother social activity in school. Many mobile phones are banned in school locker room facilities,

public restrooms and swimming pools due to the built-in cameras that most phones now feature.

A recently published study has reviewed the incidence of mobile phone use while cycling and its

effects on behaviour and safety.

5.4 Privacy

Cell phones have numerous privacy issues. Governments, law enforcement and intelligenceservices use mobiles to perform surveillance in the UKand the US. They possess technology to

remotely activate the microphones in cell phones in order to listen to conversations that take

place near to the person who holds the phone.

Mobile phones are also commonly used to collect location data. While the phone is turned on,the geographical location of a mobile phone can be determined easily (whether it is being used or

not), using a technique known multilateration to calculate the differences in time for a signal to

travel from the cell phone to each of several cell towers near the owner of the phone.[35][36]

6. Environmental issues

The ubiquitousness and rapid technological change has led to mobile phones becoming a

component of the waste stream. Electronic waste such as mobile phones contain materials that

are toxic when they enter into ecosystems and recycling is now carried out to some extent.

8. Future evolution: Broadband Fourth generation(4G)

The recently released 4th generation, also known as Beyond 3G, aims to provide broadband

wireless access with nominal data rates of 100 Mbit/s to fast moving devices, and 1 Gbit/s to

stationary devices defined by the ITU-R[37] 4G systems may be based on the 3GPP LTE (LongTerm Evolution) cellular standard, offering peak bit rates of 326.4 Mbit/s. It may perhaps also be

based on WiMax orFlash-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-carriermodulation 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, andstreamed multimedia can be given to users on a "Anytime, Anywhere" basis, and at much higher

data rates than previous generations. Sprint in the US has claimed its WiMax network to be "4G

network" which most cellular telecoms standardization experts dispute repeatedly around theworld. Sprint's 4G is seen as a marketing gimmick as WiMax itself is part of the 3G air interface.

The officially accepted, ITU ratified standards-based 4G networks are not expected to be

commercially launched until 2011.

9. Comparison to similar systems

Car phoneA type of telephone permanently mounted in a vehicle, these often have more powerful

transmitters, an external antenna and loudspeaker for hands free use. They usuallyconnect to the same networks as regular mobile phones.

Cordless telephone (portable phone)Cordless phones are telephones which use one or more radio handsets in place of a wired

handset. The handsets connect wirelessly to a base station, which in turn connects to a

conventional land line for calling. Unlike mobile phones, cordless phones use private

base stations (belonging to the land-line subscriber), which are not shared.

Professional Mobile RadioAdvanced professional mobile radio systems can be very similar to mobile phonesystems. Notably, the IDEN standard has been used as both a private trunked radio

system as well as the technology for several large public providers. Similar attempts have

even been made to use TETRA, the European digital PMR standard, to implement public

This type of phone communicates directly with an artificial satellite, which in turn relays

calls to a base station or another satellite phone. A single satellite can provide coverage to

a much greater area than terrestrial base stations. Since satellite phones are costly, theiruse is typically limited to people in remote areas where no mobile phone coverage exists,

such as mountain climbers, mariners in the open sea, and news reporters at disaster sites.

IP PhoneThis type of phone delivers or receives calls overinternet, LAN orWANnetworks using

VoIP as opposed to traditional CDMAand GSM networks. In business, the majority of

these IP Phones tend to be connected via wired Ethernet, however wireless varieties doexist. Several vendors have developed standalone Wi-Fi phones. Additionally, some

cellular mobile phones include the ability to place VoIP calls over cellular high speed

data networks and/or wireless internet.
