Mobile computing has three
aspects:
This aspect addresses communication
issues in ad-hoc and infrastructure
networks as well as communication
properties, protocols, data formats andconcrete technologies.
It allows transmission of voice and
multimedia data via a computer or a
mobile device without having
connected to any physical or fixed
link. It is evolving day by day and has
become a must have for everyone.It is
the exchange of voice and data using
a communication infrastructure at the
same time regardless of any physical
link.
This aspect is on the hardware, e.g.,
mobile devices or device components.
- Mobile hardware is outpacing
software capabilities and the mobile
user experience.
Mobile phones have the capabilities in
terms of hardware and processing
power and network connectivity that
desktop computers had a few years
ago. These devices clearly have
desktop mobile computing
capabilities.
faster touch screens and better-
designed keyboards, along with the
use of conventional wireless networks
and high-speed networks with
contemporary Web browsers, will
give users an experience very much
like that of a desktop PC. "Not that that
experience is the exact same one as
you'd have on your desktop, but the
browsers are becoming every bit as
capable on mobile phones as the ones
on your desktops,"
This aspect deals with the
characteristics and requirements of
mobile applications.
Characteristics of mobile applications:

4/18
2.3.1 Connectivity
Apps are always online as the device isconstantly logged in to the mobile
network. This allows user specificinformation or notifications beingpushed to the App as they areavailable. In combination with theubiquity of mobile applications, this isthe most important characteristic. Aservice, that must be called actively to get a reaction is useless in a mobile
environment. And with the growingnumber of Apps on each smartphone,this push-functionality becomescritical to keep an App in the usersmind
2.3.2 Convenience
An emotional design and a simple
(one-handed) handling guarantees ahigh acceptance. A good App can doits job in different contexts and fastvarying situations (changingenvironmental light and noise,unsteady movement of the device,etc.). So the information architectureand the overall usability must be
planed with care to create a fittingand joyful interaction flow. Of course good content also counts toconvenience. Analysing the usersneeds and creating a useful idea out of it is still essential.
2.3.3 Localization
Localization and the possibility tooffer location-based information is a
key feature that makes mobility vividand practical. It separates the wheatfrom the chaff as it embeds the App tothe users context. Sure, this feature
might not make sense for every Appbut localization must not always bethought of as the big thing. Just think of automatically associate the locationwith a note or photo or by justlimiting possible options or by sortingplaces. It can be useful in little, justcreating a good experience for theuser.
2.3.4 Reachability
Reachability covers a more socialattribute given by the nature of mobileapplications itself. A good App canreally be used and more importantmakes sense anywhere at any time.The core of mobile devices is to beused anywhere at anytime. The sameis true for Apps where reachability has become availability. Not in senseof usage, but in sense of updatedinformation and perpetual usefulness.To much academic? Think of actualcontent round the clock, time-awareoptions or (again) context sensitivity.
2.3.5 Security
Security has several facets. The datatransferred over the network must beencrypted through the carriernetwork. As some Apps sync data withonline, web-based applications, thestorage of this data on the server must

also be secured. Another aspectconcerns the data on the device itself. Idont want anybody playing arround
with my mobile phone getting accessto my bank account data. Mobility isdelicate, an so is the date aggregatedand generated in this context.
2.3.6 Personalization
Creating personalized content basedon individual usage or context isanother characteristic. It builds on allprevious characteristics as it is a kindof melting down of all of them. I wantmy App fitting my needs and I wantmy App behaving like I want it to do.This need covers not only personalizedcontent but also control over datastored, shared or used for furtheractions. The option of turninglocalization on or off is truepersonalization. An individualbackground or personal categories areconvenience
2.4 Requirements of mobilesoftware:
As companies rely on Mobileapplication development to satisfy business needs, a number of requirements to a mobile platformcome into sight. Most critical of themare as follows:
1. Desktop application integration.This includes accurate datasynchronization with encryption and
the possibility to manage data offline.If you need timely
access to important data stored on your desktop, including e-mails,event alerts, and customer data, thanproper integration is a must.
2. Multi-tasking. However flawlessMobile application development,mobile device resources are limited,and multi-tasking appears to be oneof the key ways to increaseproductivity.
3. Minimization of traffic amount
between a server and a mobiledevice, which contributes to timeand cost savings.
4. User-friendly interface that allowsaccomplishing necessary tasks by fewer operations.
5. The last, but not the least of requirements is lower total cost of
ownership (TCO) and support costs.Implementation of a mobile platformacross the enterprise must beestimated beforehand and suchfactors, as support and upgrade costs,are of importance, as well.
To satisfy the mentioned
requirements, mobile applicationdevelopment solutions are offered in

great diversity by each platformprovider. Microsoft, for instance, is getting prepared for Windows Mobile7 launch. Google, on the other hand,armed with the forthcoming GoogleNexus One, is trying to compete by incorporating Android with existingGoogle Apps, such as Google Docs,Gmail, Google Calendar, and other.Apple puts emphasis on businessfeatures, providing integration withMS Exchange, as well as dataencryption, GPS, etc
3 .DEVICES
3.1 CAPUTER
is the predominantterm used to describe a category of mobile computer designed ormodified to specifically be installedand run in automobiles. Originally these were based on industrialpersonal computer technology, but assmartphones and PDAs have becomemore powerful, and have includeduseful technologies like GPS andBluetooth, they have become thepredominant base platform fordeveloping carputers.
Many do-it-your-selfers have builtcarputers from laptops and small formfactor computers like netbooks.
The recent popularity of carputers has
caused the creation of more advancedunits that use touch screen interfaces,
integrate with vehicles via OBD-II link, and offer a variety of other add-ons like rear-view cameras and GPS. Itis now possible to find assembledcarputers complete with wirelesscapabilities and built-in microphonesfor sale on the internet.
Police cars often have carputers,known as Mobile data terminals.
3.2.PERSONAL DIGITALASSISTANT
A( ), also known as a
, or,[1][2][3] is a mobile device that
functions as a personal information
manager. Current PDAs often have theability to connect to the Internet. APDA has an electronic visual display , enabling it to include a web browser, but some newer models also haveaudio capabilities, enabling them to beused as mobile phones or portablemedia players. Many PDAs can accessthe Internet, intranets or extranets viaWi-Fi or Wireless Wide AreaNetworks. Many PDAs employ touchscreen technology.
The first PDA was released in 1986 by Psion, the Organizer II. Followed by Psion's Series 3, in 1991, which beganto resemble the more familiar PDAstyle. It also had a full keyboard. [4][5]

The term PDA was first used on January 7, 1992 by Apple Computer CEO John Sculley at the ConsumerElectronics Show in Las Vegas, Nevada, referring to the AppleNewton. In 1996, Nokia introducedthe first mobile phone with full PDAfunctionality, the 9000Communicator, which grew tobecome the world's best-selling PDA.The Communicator spawned a new category of mobile phones: the "PDAphone", now called"smartphone".Another early entrant in this marketwas Palm, with a line of PDA products which began with the March 1996Pilot 1000.
Today, almost all PDAs aresmartphones. Over 150 million
smartphones are sold each year, while"stand-alone" PDAs without phonefunctionality sell only about 3 millionunits per year.[6]
3.2.1 FEATURES OF PDA
Touch screen Memory cards Wired connectivity Wireless connectivity Synchronization
3.3 SMART PHONES
A is a high-endmobile phone built on a mobilecomputing platform, with moreadvanced computing ability andconnectivity than a contemporary
feature phone.[1][2][3] The firstsmartphones were devices that mainly combined the functions of a personaldigital assistant (PDA) and a mobilephone or camera phone. Today'smodels also serve to combine thefunctions of portable media players, low-end compact digital cameras,
pocket video cameras, and GPS navigation units. Modernsmartphones typically also includehigh-resolution touchscreens, webbrowsers that can access and properly display standard web pages ratherthan just mobile-optimized sites, andhigh-speed data access via Wi-Fi and
mobile broadband.
The most common mobile operatingsystems (OS) used by modernsmartphones include Google'sAndroid, Apple's iOS, Microsoft'sWindows Phone, Nokia's Symbian, RIM's BlackBerry OS, and embeddedLinux distributions such as Maemo and MeeGo. Such operating systems

can be installed on many differentphone models, and typically eachdevice can receive multiple OSsoftware updates over its lifetime.
The distinction between smartphonesand feature phones can be vague andthere is no official definition for whatconstitutes the difference betweenthem. One of the most significantdifferences is that the advancedapplication programming interfaces
(APIs) on smartphones for runningthird-party application s[4] can allow those applications to have betterintegration with the phone's OS andhardware than is typical with featurephones. In comparison, feature phonesmore commonly run on proprietary firmware, with third-party software
support through platforms such as Java ME or BREW.[1] An additionalcomplication in distinguishingbetween smartphones and featurephones is that over time thecapabilities of new models of featurephones can increase to exceed those of phones that had been promoted as
smartphones in the past.3.4 TABLET COMPUTER
A , or a , is amobile computer, larger than a mobilephone or personal digital assistant, integrated into a flat touch screen andprimarily operated by touching the
screen rather than using a physicalkeyboard. It often uses an onscreen
virtual keyboard, a passive stylus pen, or a digital pen[citation needed ].[1][2]
The term may also apply to a variety
of form factors that differ in positionof the
screen with respect to a keyboard. Thestandard form is called slate , whichdoes not have an integrated keyboardbut may be connected to one with awireless link or a USB port.
Convertible notebook computers havean integrated keyboard that can behidden by a swivel joint or slide joint,exposing only the screen for touchoperation. Hybrids have a detachablekeyboard so that the touch screen canbe used as a stand-alone tablet.Booklets include two touch screens,

electronic devices based on theconcept appeared at the end of the20th century. During the 2000sMicrosoft attempted a relatively unsuccessful product line withMicrosoft Tablet PC, which carved aniche market at hospitals and outdoorbusinesses. In 2010 Apple released theiPad based on the technology developed in parallel with theirprevious iPhone, and reachedworldwide commercial success
3.5 ULTRA-MOBILE PC
An [1] (or )
is a small form factor version of a pencomputer, a class of laptop whosespecifications were launched by Microsoft and Intel in spring 2006.Sony had already made a first attemptin this direction in 2004 with its VaioU series, which was however only soldin Asia. UMPCs are smaller thansubnotebooks, have a TFT display measuring (diagonally) about 12.7 to
17.8 cm, and are operated like tabletPCs using a touchscreen or a stylus. There is no clear boundary betweensubnotebooks and ultra-mobile PCs.
The first-generation UMPCs weresimple PCs running Linux or anadapted version of Microsoft's tabletPC operating system. With theannouncement of the UMPC,Microsoft dropped the licensingrequirement that tablet PCs must
support proximity sensing of thestylus, which Microsoft termed"hovering".
Second-generation UMPCs use lesselectricity and can therefore be usedlonger (up to five hours) and alsosupport Windows Vista.
Originally codenamed, the project was launched in
2006 as a collaboration betweenMicrosoft, Intel, Samsung, and a few others. Despite prediction of thedemise of UMPC device category according to CNET[2] the UMPCcategory appears to continue to be inexistence, however, it has largely beensupplanted by tablet computers [3] asevidenced by the introduction of Apple iPad, Google Android,BlackBerry Tablet OS, and Nokia'supcoming MeeGo.

areminiature electronic devices that areworn by the bearer under, with or ontop of clothing. This class of wearabletechnology has been developed for general or special purposeinformation technologies and mediadevelopment. Wearable computers areespecially useful for applications thatrequire more complex computationalsupport than just hardware codedlogics.
One of the main features of awearable computer is consistency.
There is a constant interaction between the computer and user, i.e.there is no need to turn the device onor off. Another feature is the ability tomulti-task. It is not necessary to stopwhat you are doing to use the device;it is augmented into all other actions.These devices can be incorporated by
the user to act like a prosthetic. It can
therefore be an extension of the usersmind and/or body.
Many issues are common to the
wearables as with mobile computing, ambient intelligence and ubiquitouscomputing research communities, including power management andheat dissipation, softwarearchitectures, wireless and personalarea networks.
The International Symposium onWearable Computers is the longest-running academic conference on thesubject of wearable computers.
As indicated by its name, the objective
of mobile telecommunications systems
is to provide communication between
mobile distant persons. These systems
only supported direct voice
communication or telephony between
two participants, but supplementary
services like call forwarding, barring
and voice mail were added later on.
The mobile telephony service is
realized by components represented
by grey ovals that are distributed both

on the mobile phone, also called
Mobile Station (MS) and on the mobile
network. On the MS, there are
components both on the Mobile
Equipment (ME) and on the subscriber
Identity Module (SIM).
It does not take long time
before there is a need for more
advanced call control services like call
forwarding, barring, voice mail,
premium call, etc. As shown in Figure
3 an IN (Intelligent Network [1])
Service Control Point (SCP) is
introduced in the mobile network to
allow the implementation of
supplementary services. It is worth
mentioning that these services are
derivatives centered around the voice
communication service. Another
restriction is that the SCP is
implemented on equipment
manufacturer proprietary
technologies. The SCP is also located
inside the telecom operator domain
making third party service
development difficult.
The telecom operators want to
have other services than telephony and its derivatives and turn to the
SIM, which are their property.
Unfortunately, although the SIM is a
smart card having both processing
and storage capabilities necessary for
new services. The SIM is supposed to
be the slave executing orders from its
master, the ME. To remedy this, the
SIM Application Tool-kit (SAT) [2] is
introduced to allow
applications/services residing on the
7/30/2019 Gprec Word
12/18
SIM to control the input and output
units. With SAT it is possible to
develop on the SIM but there are
many restrictions. First SAT
applications should be small in size.
Secondly, the installation of
applications on the SIM is controlled
by operators who are reluctant to
open the access due to security.
SMS-C is responsible to
store and forward messages to and
from mobile phone ( Fig 3). In the
illustration, components used for SMS
are the client (C) in the ME advanced
SMS services are implemented by
perlscripets. Provisioning of SMS
services requires installation of the
above mentioned application on an
SMS Gateway the system running the
SMS Gateway to act as an SMSC itself
(e.g. a PC using a radio modem
through a serial port). To have direct
access to an SMSC requires
cooperation with the operator that
owns the SMSC, which often can
provide a TCP connection for
sending/receiving SMS messages part
of a service. The advantage of the
above solution is that to receive
revenue from generated traffic. The
problem with access to SMS services is
remembering both the service access
number and the additional identifiers
and parameters for a specific service
(the protocol )
Wireless Application Protocol
(WAP) [5] was to provide access to the
WWW on handheld terminals. A
micro browser installed in the Mobile
Equipment is communicating with a
WAP Proxy introduced between the
Internet and the mobile network to
convert Internet protocols to Wireless
binary protocols as shown in Figure 3.
On the terminal side, a WAP browser
is located in the ME and services are
connected to a Web server on the
7/30/2019 Gprec Word
13/18
network side. Development of WAP
services can be performed by
programming experience. One
restriction of the technology is that it
is not possible to access ordinary web
pages using a WAP browser.
Unlike a
computer, the functionality of the
mobile phones is defined at
manufacture time and it is not
possible to install new applications.
With introduction of the J2ME
CLDC/MIDP vast amount of
sophisticated applications, called
MIDLETS can be found on the
Internet. With J2ME, it is possible to
develop dynamic standalone
applications. When it comes to SMS,
there are still some restrictions in
J2ME, such as access to the standard
inbox for SMS messages on a handset
is not allowed.
This section aims at identifying and
elucidating the advanced pieces and
hence contribute to the definition of
advanced architecture.
Mobility is the ultimate requirement
for mobile services. The mobility
properties of a service are dependent
on the architecture and particularly
on the location of the components
making up the service. Considering a
service as consisting of two
components, service logic and service
content , makes the analysis easier. In
early mobile telecom services the
service logic was embedded in the
edicate hardware components. This
has been a hindrance for development
of flexible services, these services will
by default not be accessible from
outside an operator domain. To
enhance the mobility of ser-vices, it is
necessary to decouple the service logic
from the system components.

computing standards on thefleet. One can easily attack theVPN through a huge numberof networks interconnectedthrough the line.
: When apower outlet or portable generator is not available,mobile computers must rely entirely on battery power.Combined with the compact
size of many mobile devices,this often means unusually expensive batteries must beused to obtain the necessary battery life.
:Weather, terrain, and the
range from the nearest signalpoint can all interfere withsignal reception. Reception intunnels, some buildings, andrural areas is often poor.
:People who use mobile deviceswhile driving are oftendistracted from driving arethus assumed more likely to beinvolved in traffic accidents.[3] (While this may seem obvious,there is considerablediscussion about whetherbanning mobile device usewhile driving reduces
accidents or not.[4][5]) Cell
phones may interfere withsensitive medical devices.There are allegations that cellphone signals may causehealth problems.[citation needed ]
:Screens and keyboards tend tobe small, which may makethem hard to use. Alternateinput methods such as speechor handwriting recognition
require training.
As oppose to the benefits of being ableto access information from any location through wirelesstransmission, there is it faults with theneed for security protection. In awireless mobile communicationenvironment, the messagestransmitted over the wireless mediumare more susceptible to eavesdroppingthan in a wired network. Also, it ispossible for any user to access themobile communication system usingfalse identity.
In order to provide security fromeavesdropping or false identities,systems use encryption. whichprovides confidentiality of themessages sent over wireless channeland to authenticate. The main idea is
to conceal the content of the messages

Main articles:Mobile device and Portable computer
There are several categories of portable computing devices that canrun on batteries but are not usually classified as laptops: portable
computers, keyboardless tablet PCs,Internet tablets, PDAs, ultra mobilePCs (UMPCs) and smartphones.
A portable computer is a general-purpose computer that can be easily moved from place to place, but cannotbe used while in transit, usually
because it requires some "setting-up"and an AC power source. The mostfamous example is the Osborne 1. Portable computers are also called a"transportable" or a "luggable" PC.
A tablet computer that lacks akeyboard (also known as a non-convertible tablet) is shaped like slateor a paper notebook, features atouchscreen with a stylus andhandwriting recognition software.Tablets may not be best suited forapplications requiring a physicalkeyboard for typing, but are otherwisecapable of carrying out most tasks thatan ordinary laptop would be able toperform.
A personal digital assistant (PDA) is asmall, usually pocket-sized, computerwith limited functionality. It isintended to supplement and tosynchronize with a desktop computer, giving access to contacts, addressbook, notes, e-mail and other features.
A Palm TX PDA
A PDA with a web browser is an, an Internet appliance
in tablet form. Unlike a tablet PC, anInternet tablet does not have muchcomputing power and its applicationssuite is limited, and it can not replacea general purpose computer. Internettablets typically feature an MP3 andvideo player, a web browser, a chatapplication and a picture viewer.
An ultra mobile PC is a full-featured,PDA-sized computer running a general-purpose operating system.
A smartphone has a wide range of features and installable applications.
A carputer is a computing deviceinstalled in an automobile. It operatesas a wireless computer, sound system,

A Fly Fusion Pentop Computer is acomputing device the size and shapeof a pen. It functions as a writingutensil, MP3 player, languagetranslator, digital storage device, andcalculator.[7]
Boundaries that separate these
categories are blurry at times. Forexample, the OQO UMPC is also aPDA-sized tablet PC; the Apple eMate had the clamshell form factor of alaptop, but ran PDA software. The HP Omnibook line of laptops includedsome devices small more enough to becalled ultra mobile PCs. The hardware
of the Nokia 770 internet tablet isessentially the same as that of a PDAsuch as the Zaurus 6000; the only reason it's not called a PDA is that itdoes not have PIM software. On theother hand, both the 770 and theZaurus can run some desktop Linuxsoftware, usually with modifications.
Wireless data connections used inmobile computing take three generalforms.[8] Cellular data service usestechnologies such as GSM, CDMA orGPRS, and more recently 3G networkssuch as W-CDMA, EDGE or
CDMA2000.[9][10]
These networks areusually available within range of
commercial cell towers. Wi-Fi connections offer higherperformance,[11] may be either on aprivate business network or accessedthrough public hotspots, and have atypical range of 100 feet indoors andup to 1000 feet outdoors.[12] SatelliteInternet access covers areas wherecellular and Wi-Fi are not available[13] and may be set up anywhere the userhas a line of sight to the satellite'slocation,[14] which for satellites in geostationary orbit means having anunobstructed view of the southernsky .[8] Some enterprise deploymentscombine networks from multiplecellular networks or use a mix of cellular, Wi-Fi and satellite.[15] Whenusing a mix of networks, a mobilevirtual private network (mobile VPN)
not only handles the security concerns, but also performs themultiple network logins automatically and keeps the application connectionsalive to prevent crashes or data lossduring network transitions orcoverage loss.[16][
6. Conclusion:This paper presents an
analysis of the evolutionary path of
mobile services, from early voice
communication services to prospects

help excel the future of mobile
services. Each of the concepts
discussed around mobile services in
this paper are on their own and of

elaborated in separate studies. Thus,
the discussions in this paper are
preliminary and do address only the
basic structures and further works
will be carried out.
