When 3G services were introduced, big mobile phone companies had
to pay around £100bn which made the launch of 3G harder.

Now when all the major leading mobile phone companies are
preparing for the launch of the next generation of fast wireless
broadband, the same bill issue might occur.

This is the reason for which six of the world's leading mobile
phone companies have joined their powers to take the steps to
avoid a repeat bill of such amount. The companies intend to
lobby governments, regulators and the rest of the industry to
make sure that the next generation of fast wireless broadband
which is called 4G, is not as expensive to introduce as its
predecessor.

The idea is that the mobile phone industry looks to broadband
internet access as a new way to make money. O2, owned by
Telefonica, bought the residential internet service provider Be
Broadband, a move that will allow O2 to offer converged mobile
and fixed-line services.

Most players in the industry think that the future is mobile
broadband and believe that "the convergence strategy seems to be
a defensive strategy as the major mobile phone companies are
scared that the fixed-line operators are coming after their
business." (Jim Hyde, head of T-Mobile's UK business).

BT seems to be on the side of converged mobile and fixed-line
phone services and offered a package with interactive TV,
videophoning and other integrated home media services including
video on demand, voice-over-internet phone calls and wireless
broadband.

T-Mobile, fair to its strategy, is launching an upgrade to its
existing equipment that will make its 3G network four times
faster. The service will cost £17 a month for up to one gigabyte
of web surfing while Vodafone that launched a similar service
but with a quarter of the capacity will charge £25.

Although these new services seem overwhelming on the market,
they are only the opening of what the industry will offer when
4G, a super-fast mobile broadband technology will be put into
work. With speeds of 20MB a second there is no need to have a
fixed-line broadband connection. The new service aims to speeds
of 20MB a second which will make the fixed-line broadband
connection almost useless.

At this point nothing can stop the industry to develop in this
direction, except maybe for the governments who are looking to
make billions from licensing spectrum and technology companies
looking to tie up intellectual property rights. But here comes
the role of the new created Next Generation Mobile Network
(NGMN) Forum that includes companies like Vodafone, T-Mobile,
Orange, KPN, DoCoMo and China Mobile and will lobby regulators
to allow operators to use their existing spectrum to run the
super-fast wireless broadband.

Overall Effects- Industry, Social Activities and Mobile
Communications

The 4th Generation (4G) mobile communications systems are
projected to be carried out around 2010. World Over the research
on 4G (Fourth Generation) Mobile Communications is in progress
since the last 6 years. The technology is still in evolution but
Countries have already started committing themselves to its
implementation. India has said that it would leapfrog from 2G to
4G bypassing the 3G Technology. China, Korea and Japan are
jointly developing 4G Phones; China will implement 4G technology
for the Beijing Olympic games. WiMax Technology is on its last
legs because it does not support VOIP. Data transfers will
happen at LAN Speeds of 100Mbps.The World is looking up to 4G
for transformation of the way people do day-to-day business.
Once the technology evolves the hand phone used in 4G mobile

Industry, Social Activities and Mobile Communications

From the viewpoint of industries, this change infers a great
transformation of business structure, particularly in industries
targeted at consumers, and an emergence of new businesses.
First, it will become possible for entertainment (such as music
or video) businesses to deliver products to the consumers in a
moment using fast-speed 4G mobile systems. Conventional package
distribution could be replaced by distribution through mobile
networks, which may develop into one pillar of the entertainment
businesses.

In services offered to people-such as media calm, education,
government services-the form of service offering may shift in
varying degrees into a structure where "a service is delivered
to the user" instead of "users are required to go out to receive
service". Mobile government services and remote education is
likely to be provided purely as an application on mobile
networks.

Although it may be difficult to realize full-scale on-line
medical service right away, an environment where doctors with
advanced mobile medical devices visit patient's homes to provide
treatment using special mobile services are considered
sufficiently possible In the fields of life support and
security, new services that have not been possible on
conventional telecommunications networks, i.e., shopping
assistance linked with home information appliances, or
round-the-clock health management services, etc., could be
realized by 4G mobile systems.

These services are projected to acquire many users given the
current social trends, i.e., an aging society and people's
increasing awareness of health and safety.

4G mobile systems and the development of mobile services are
thus projected to ease a conversion from old industry/business
structures, and lead to a creation of new industries and
markets. Furthermore, such change in industry structure is also
expected to stimulate capital investments not only in the
telecommunications sector but also in various other industries,
and create new demands amongst the consumers for terminal
equipment to receive a wide range of mobile services. The
advancement in mobile services are likely to enlarge the markets
for a wide range of products that are often used in daily life,
including mobile terminals, information appliances, home
network, intelligent vehicles, between others.

(1) Enriched and Cultural Life - Enriched life-able to
communicate with friends and families anytime Due to the
enhancements of mobile services, it will become possible to
provide an environment in which people can communicate with
another person in a distant location with a sense of reality as
if the person is nearby. In such an environment, mobile users
will be able to enjoy richer lives being able to feel the bond
with family members and friends anytime no matter where they
are. - A cultural life-able to receive informatio n of your
choice and easily obtain the right entertainment anytime you
like Advancements in mobile networks will enable people to
obtain a wide range of information at any location without
constraints, or receive education of their choice. Such a
cultural life enabled by mobile communications will be realized
in an environment where intellectual property rights are
protected to ensure free and secure exchange of information and
knowledge. (2) More Flexible and Diversified Life - Flexible and
Diversified Life-able to work regardless of home circumstances
Monitoring through visual communications, work at home by
interactive communications,and controlling robots from mobile
terminals are all expected to become a reality. In such
environments, people can work in a more flexible manner
regardless of the circumstances, i.e., work at home while
nursing infants or elderly family members with health concerns.
- Environment that enables various people to participate freely
in social activities The realization of electronic governments
will make it easier for people-including the elderly or
handicapped-to participate in social activities from mobile
terminals. An active and rigorous society can be created through
voluntary dissemination of information from individuals and
people's spontaneous participation in society building. (3) More
Comfortable and Safer Life - More Comfortable and Safer Life-saf
ety is ensured anytime, anywhere.The realization of a society
where connections to medical institutions, private organizations
or police can be made anytime from anywhere will give assurance
for people's lives, health, safety and crime prevention,
enabling them to live a more comfortable and safer life. -
Convenient and Comfortable Life-able to gain access services on
highly convenient networks in a secure manner Through secure
authentication and billing systems, people will be able to carry
out commercial transactions on mobile networks without worries,
and easily enjoy convenient services with a high degree of
reliability. (4) More Personnel and Convenient Life - Personnel
Life-possible to freel y select from a wide range of services
based on individual preferences Users' needs for service-the
type of service, the frequency of use and payment method,
etc.-vary between individuals. It will become pos sible to
customize freely the usage style, i.e., the type/provider of
service, place of use, terminal, etc., depending on individual
preferences. - Extremely convenient life-what you want to do now
can be done right away Almost every service you want to use
right now-ranging from advanced information search as if you
were in a large library to net shopping with a feeling as if you
went out to a shop-will be made available with the mobile
terminal at hand. Request and wishes of individuals will be
realized in a convenient fashion through various services
anytime and anywhere.

The Awakened Dragon and the Crouching Tiger - How China and
India are Pushing the Envelope in Telecom

There is considerable scope for the development of
telecommunications to benefit countries such as India and China.
Ericsson is of the opinion that the provision of 3G services can
also be accompanied by other services such as mobile TV and
high-speed data services without too much investment.

Ericsson's view of Cingular's deployment of the 850 MHz band for
the development of 3G services is that this is a very clear
indication of the popularity of Wideband Code Division Multiple
Accessor WCDMA in markets that have good scope for expansion.
Cingular feels that this band is best suited to providing
connectivity for rural population because this frequency can
accomplish its objective with significantly fewer base stations.

<b>Hope for the future?</b>

As a result, the 850 MHz band can play an important part in
providing telecom links among communities that are financially
weak. Millions of people in India live in the villages and often
lack the most basic of health care and other essential services.
The Indian government has pledged to work towards improved
coverage for rural communities to the extent of aiming for as
much as 75% coverage in these areas by the end of 2006.

<b>Running neck and neck?</b>

India and China are both pushing for the development of
economically priced 3G handsets. It was expected that there
would be about 40 new manufacturers producing such handsets in
China by 2005. The deployment of WCDMA may make it possible to
set up terminals for fixed line-cellular services in rural areas.

This will mean that users will be able to make calls as well as
access the Internet at speeds of 384 kbps. The use of High Speed
Downlink Packet Access or HSDPA technology could increase this
speed to 1 Mbps.

<b>Scaling new heights with HSDPA</b>

The use of HSDPA can do a great deal to increase efficiency by
expanding capacity and increasing the speeds at which data are
transferred. This technology will enable operators to attend to
the requirements of different communities and charge them a
nominal amount to recover the investment. In fact, HSDPA offers
potential for developments that would not be possible with GSM.

<b>Hard facts</b>

India enjoyed one of the highest rates of growth with the number
of cellular subscribers in the country expanding at 105% between
1995 and 2001. This was a higher rate of growth than that of the
world as a whole and even of China, which recorded a growth rate
of 85% in terms of cellular subscribers.

However, statistics show that India's teledensity is far lower
than it should be and that the country has been outpaced by
others such as Libya and Namibia, which have fared much better.
China and Indonesia are also way ahead of India in this regard,
a fact that does not show India up too well, considering that
both these countries were level with India at teledensity levels
of 0.6 in 1990.

The only other comparisons that can be made with countries that
have had a worse performance are those of Pakistan, Bangladesh
and Nigeria. Considering that India is a democratic country with
a fair proportion of technically qualified people, it appears
that infrastructure factors could be behind India's poor showing
in this regard.

On the other hand, you can hardly ignore the fact that China now
has approximately 145 million cellular subscribers. When you
consider that the country has 179 million main lines, that is
saying quite a lot, don't you think?

It's also been suggested the proliferation of cellular phones in
India presents a threat to companies offering fixed line
services in India. You could say it would make more sense for
wireless services to surpass fixed line services in a country
like India. India's fixed line network can hardly compare with
that of the United States.

<b>Critical differences</b>

The Finance Minister, Mr. P. Chidambaram suggested that it would
be a mistake for India to follow the example set by China. China
chose to compel international telecom companies to partner with
Chinese companies. The idea was to encourage the development of
manufacturing facilities within the country.

This approach, he felt, would only slow down the growth of the
country's telecom industry. He emphasized that India was
depending heavily on BPOs and the service model. He therefore
claimed that India would not benefit from following China's
example.

He also stated that China welcomed foreign investment and
equipment suppliers, but China Telecom held the monopoly for
operating companies. Subsequently, that monopoly gave way, with
China Telecom being allocated 21 provinces, while Netcom was
granted 10 provinces.

China introduced mobile phone services in 1992, two years before
India, although this was the same year that India applied for
telecom licenses. While China has two government owned mobile
operators, India has eight. These include two public sector
undertakings. While China is still closed to foreign investment
in the telecom sector, the FDI cap in India is 49%. However,
while India now has 42 million mobile phone subscribers, China
has more than 300 million, despite the absence of FDI.

<b>Room for improvement</b>

Mr.Chidambaram's conclusion was that although there had been
spectacular growth in the number of telephone lines, it would
take nothing less than major foreign investment to maintain the
pace of growth and accomplish network coverage of 70%. While it
is certainly true that India needs investment in the telecom
sector, it is doubtful whether this would give villages and
other remote areas access to telecom links.

Wireless Standards Development This section discusses the
evolution of some of the wireless networking standards and the
types of services they support.The phased evolution of wireless
networking standards are referred to as generations:

* 1G--First generation. 1G refers to the initial category of
mobile wireless networks that used only analog technology and
were developed primarily for voice services. Advanced Mobile
Phone Service (AMPS) is an example of a 1G mobile network
standard.

* 2G--Second generation. 2G refers generically to a category of
mobile wireless networks and services that use digital
technology. 2G wireless networks introduce support for data
services. GSM, TDMA and CDMA are examples of 2G mobile network
standards.

* 2G+--Second generation plus. 2G+ refers generically to a
category of mobile wireless networks that have a packet data
overlay built on top of the circuit-switched voice network to
support higher data rates than 2G mobile networks (2G networks
support data in a circuit-switched model). General Packet Radio
Service (GPRS) is an example of a 2G+ mobile network standard.
There is a similar packet data overlay concept for CDMA called
Packet Data Services Node (PDSN), but this is considered 3G as
part of the CDMA 1x solution.

* 3G--Third generation. 3G refers generically to a category of
next-generation mobile networks which operate at a higher
frequency bandwidth (typically 2.1 GHz and higher) and have a
larger channel bandwidth. This enables 3G networks to support
very high data rates, up to 2 Mbps. With the higher bandwidth,
more data and multimedia services are possible. 3G refers to the
radio network and RF technology, and does not affect the
switching core. The switching infrastructure for 3G is still
based on MSCs and the TDM model. The Universal Mobile Telephone
Service (UMTS), based on the Wideband CDMA (W-CDMA) R-99 and
CDMA 2000, are examples of 3G radio networks that are being
developed to fulfill the requirements in the International
Mobile Telecommunications-2000 (IMT-2000) standard by the
International Telecommunication Union (ITU).

* 3G+--Third generation plus. 3G+ refers to an advanced level of
3G that introduces the concept of an all-IP switching core. An
all-IP switching core means that IP replaces the TDM-based MSC
infrastructure with IP-based transport and IP-based signaling.
IP-based signaling is implemented with new protocols like
Session Initiation Protocol (SIP) and Media Gateway Control
Protocol (MGCP). In 3G+ networks, the traditional MSC
implementation goes away and the various MSC functions are
redistributed to several other elements. A good example of this
evolution in the switching core from TDM to packets is 3GPP's R4
and R5 architecture. 3GPP2 also has adopted a similar trend to
transition to an all-IP network. There are also initiatives
under way to develop and migrate to a true end-to-end, all-IP
mobile wireless network where both the switching core and the
RAN are IP based. This evolution is being loosely referred to as
R6 in 3G terminology. Global Systems for Mobile Communications
In the early 1980s, many countries in Europe witnessed a rapid
expansion of analog cellular telephone systems. However, each
country developed its own system, and interoperability across
borders became a limiting factor. In 1982, the Conference of
European Post and Telecommunications (CEPT), an association of
telephone and telegraph operators in Europe, established a
working group to develop a new public land mobile system to span
the continent. Because their working language was French, the
group was called the Groupe Speciale Mobile (GSM). The GSM group
proposed the following criteria for the new mobile wireless
system: * good speech quality * low cost for terminals and
service * international roaming * handheld terminals * support
for introduction new services * spectral efficiency *
compatibility with Integrated Digital Services Network (ISDN) In
1989, the responsibility for GSM development was transferred to
the European Telecommunications Standards Institute (ETSI), and
phase 1 of the GSM specification was published in 1990. The
first commercial service was launched in 1991. When the official
language of the GSM group changed from French to English, GSM
was changed from Groupe Speciale Mobile to Global System for
Mobile Communications. In 1994, phase 2 data/fax services were
launched, and in 1995, the GSM phase 2 standard was completed.
The first GSM services in the United States were launched. GSM
uses a combination of both the time division multiple access
(TDMA) and frequency division multiple access (FDMA)
technologies. With this combination, more channels of
communications are available, and all channels are digital. The
GSM service is available in four frequency bands: *
450-MHz--Upgrade of older analog cellular systems in Scandinavia
* 900-MHz--Original band used everywhere except North America
and most of South America * 1800-MHz--New band to increase
capacity and competition used everywhere except North America
and most of South America * 1900-MHz--Personal communications
service band used in North America and much of South America.
The higher frequency bands provide additional capacity and
higher subscriber densities. One of the unique benefits of GSM
service is its capability for international roaming because of
the roaming agreements established between the various GSM
operators worldwide.

GSM Technology Differentiator One of the advantages of GSM is
that it offers a subscriber identity module (SIM), also known as
a smart card. The smart card contains a computer chip and some
non-volatile memory and is inserted into a slot in the base of
the mobile handset. The memory on the smart card holds
information about the subscriber that enables a wireless network
to provide subscriber services. The information includes: * The
subscriber's identity number * The telephone number * The
original network to which the subscriber is subscribed A smart
card can be moved from one handset to another. A handset reads
the information off the smart card and transmits it to the
network.

GSM Network Elements A GSM network consists of the following
network components: * Mobile station (MS) * Base transceiver
station (BTS) * Base station controller (BSC) * Base station
subsystem (BSS) * Mobile switching center (MSC) * Authentication
center (AuC) * Home location register (HLR) * Visitor location
register (VLR) Mobile Station The mobile station (MS) is the
starting point of a mobile wireless network. The MS can contain
the following components: * Mobile terminal (MT)--GSM cellular
handset * Terminal equipment (TE)--PC or personal digital
assistant (PDA) The MS can be two interconnected physical
devices (MT and TE) with a point-to-point interface or a single
device with both functions integrated. Base Transceiver Station
When a subscriber uses the MS to make a call in the network, the
MS transmits the call request to the base transceiver station
(BTS). The BTS includes all the radio equipment (i.e., antennas,
signal processing devices, and amplifiers) necessary for radio
transmission within a geographical area called a cell. The BTS
is responsible for establishing the link to the MS and for
modulating and demodulating radio signals between the MS and the
BTS. Base Station Controller The base station controller (BSC)
is the controlling component of the radio network, and it
manages the BTSs. The BSC reserves radio frequencies for
communications and handles the handoff between BTSs when an MS
roams from one cell to another. The BSC is responsible for
paging the MS for incoming calls. Base Station Subsystem A GSM
network is comprised of many base station subsystems (BSSs),
each controlled by a BSC. The BSS performs the necessary
functions for monitoring radio connections to the MS, coding and
decoding voice, and rate adaptation to and from the wireless
network. A BSS can contain several BTSs. Mobile Switching Center
The mobile switching center (MSC) is a digital ISDN switch that
sets up connections to other MSCs and to the BSCs. The MSCs form
the wired (fixed) backbone of a GSM network and can switch calls
to the public switched telecommunications network (PSTN). An MSC
can connect to a large number of BSCs. Equipment Identity
Register The equipment identity register (EIR) is a database
that stores the international mobile equipment identities
(IMEIs) of all the mobile stations in the network. The IMEI is
an equipment identifier assigned by the manufacturer of the
mobile station. The EIR provides security features such as
blocking calls from handsets that have been stolen. Home
Location Register The home location register (HLR) is the
central database for all users to register to the GSM network.
It stores static information about the subscribers such as the
international mobile subscriber identity (IMSI), subscribed
services, and a key for authenticating the subscriber. The HLR
also stores dynamic subscriber information (i.e., the current
location of the mobile subscriber). Authentication Center
Associated with the HLR is the authentication center (AuC); this
database contains the algorithms for authenticating subscribers
and the necessary keys for encryption to safeguard the user
input for authentication.

Visitor Location Register The visitor location register (VLR) is
a distributed database that temporarily stores information about
the mobile stations that are active in the geographic area for
which the VLR is responsible. A VLR is associated with each MSC
in the network. When a new subscriber roams into a location
area, the VLR is responsible for copying subscriber information
from the HLR to its local database. This relationship between
the VLR and HLR avoids frequent HLR database updates and long
distance signaling of the user information, allowing faster
access to subscriber information. The HLR, VLR, and AuC comprise
the management databases that support roaming (including
international roaming) in the GSM network. These databases
authenticate calls while GSM subscribers roam between the
private network and the public land mobile network (PLMN). The
types of information they store include subscriber identities,
current location area, and subscription levels. Network and
Switching Subsystem The network and switching subsystem (NSS) is
the heart of the GSM system. It connects the wireless network to
the standard wired network. It is responsible for the handoff of
calls from one BSS to another and performs services such as
charging, accounting, and roaming. Figure 2-1 shows a GSM
network and the network elements it contains.

GSM Interfaces The GSM uses various interfaces for communication
among its network elements. Figure 2-2 shows these interfaces.
Mobile wireless communication occurs over the interfaces between
the network elements in a sequential manner. In Figure 2-2, the
MS transmits to the BTS, the BTS to the BSC, and the BSC to the
MSC. Communications also occur over the interfaces to the
management databases (HLR, VLR, AuC, and EIR). Communications
might traverse multiple MSCs but ultimately must reach the
gateway MSC (GMSC). The GMSC provides the gateway to the public
switched telephone network (PSTN). A separate interface exists
between each pair of elements, and each interface requires its
own set of protocols.In the BSS block, mobile communication
occurs over the air interface to the BTS using the ISDN Link
Access Procedure-D mobile (LAP-Dm).

Figure 2-2 GSM Interfaces

This traffic channel carries speech and data. In this example,
voice operates at full-rate 13 kbps (supported by LAP-Dm), and
data operates at full-rate 9.6 kbps. The BTS communicates to the
BSC over the Abis interface using the ISDN LAP-D signaling
protocol. The BSC communicates to the GMSC via the transcoder
rate adapter unit (TRAU), which translates between 16 kbps on
the BTS side to 64 kbps on the GMSC side. This interface uses
the signaling system 7 (SS7) protocol, which defines call set-up
and call services across the interface. At the NSS, the GMSC is
the central node. Link-level traffic and signaling control
occurs over the interface between the GMSC and MSC and the
interface to the external network (PSTN, ISDN or PDN). Different
signaling protocols are used on the interfaces. Some NSS
interfaces involve only control signaling protocols with no
traffic. For example, no traffic is generated on the interfaces
between the GMSC, HLR, and VLR. Instead, these interfaces carry
only signaling using the Mobile Application Part (MAP) of the
SS7 protocol. The MAP is specified in IS-41 and defines the
application layer, signaling protocols, and procedures for
registering mobile users and handling handoffs between cellular
systems. The GMSC establishes call traffic (at 64 kbps) onto the
PSTN via the ISDN user part (ISUP), which is an SS7-based
protocol. The GMSC and MSC exchange traffic (over LAP-D at 64
kbps) and use SS7 (MAP and ISUP) control. GSM Data Services GSM
networks handle both voice and data traffic requirements of the
mobile communication by providing two modes of operation: *
Circuit switched (high-speed circuit switched data) * Packet
switched (GPRS) Circuit switching provides the customer with a
dedicated channel all the way to the destination. The customer
has exclusive use of the circuit for the duration of the call,
and is charged for the duration of the call. With packet
switching, the operator assigns one or more dedicated channels
specifically for shared use. These channels are up and running
24 hours a day, and when you need to transfer data, you access a
channel and transmit your data. Packet switching is more
efficient than circuit switching. The standard data rate of a
GSM channel is 22.8 kbps.

Behold the Next Generation
Ten years from now you'll reminisce about the days before
wireless high-speed internet, that dark era when you were
tethered to a cabled modem and computer when checking messages.
Like life before the cell phone, how did you ever put up with
it? And what will it take to make our high-speed connections
obsolete? Certainly not the spotty WiFi access that's roaming
around in coffee shops or spouting from a clueless neighbor's
home; rather, it will be a ubiquitous high-speed cell phone
network, or 3G network, so to speak. There's been a growing buzz
about 3G in the media and a few advertisers have even asked us
at ICMediaDirect.com about the impact 3G will have on
interactive advertising. It's hard to say too much about any
impact, but it isn't too early to familiarize ourselves with the
basics.

3G stands for third generation. It's basically a template for
what the next step in cell phone technology should be; it will
mean mobility with high-speed access to the Internet and data
transfer. As you may already believe, the Internet seems as slow
as molasses on most current cell phone networks. Fortunately,
things change quickly in today's dynamic, business-driven
environment. Verizon and Sprint PCS are striving to meet the
ideals of a 3G manifest destiny by using "EvDO" technology,
which is an awkward acronym for "Evolution Data
Only/Optimization". This system is a descendant of the current
digital network system CDMA, which stands for Code Division
Multiple Access. Using a single dedicated data-only radio
frequency, the EvDO network has the capacity to transfer files
and information at a speedy 500-600 kbps average rate with burst
speeds up to 2.4 mbps. While this speed is not comparable to an
average cable modem, it's still a vast improvement over standard
cell phone data capability today.

T-mobile and other digital cell phone providers have a slower
alternative technology to EvDO called EDGE. EDGE is a 1xRRT
system--an older derivative of CDMA that is easy to implement.
At best, EDGE can deliver content at 144 kbps, but slower speeds
are more likely. While this isn't even close to EvDO's speed,
it's still faster than plain old CDMA. EDGE won't supply much
in-demand content, but basic internet surfing with it is
considerably better than dial-up, which may be a relief to many.

In terms of 3G ambition, it seems that Verizon and Sprint have
the jump up on competition, but this is hardly a done-deal
monopoly. EvDO network coverage is available in selective cities
depending on the service provider, although users that subscribe
to this service also have access to the older 1xRRT system which
is present anywhere a digital signal is present.

3G networks will change access to the Internet as we know it by
delivering more information to more people who, by virtue of
mobility, will almost always be connected. The inevitable
strides that will be taken towards bridging mobile technology
and the boundless Internet will seamlessly play out through 3G's
functionality. With already over 250 million subscribers to the
3G networks globally, usage will only increase as this
technology gains popularity.

3G is a multimedia-oriented wireless technology serving products
that cater to the growing consumer appetite for content on the
go. It's voice, it's video, it's speed. The future for 3G looks
so promising that in a few short years, we won't even recognize
the common platforms we use today.

The third generation mobile phones, based on GSM standards, are
a big leap forward for mobile phone technology with more
services and features on offer than ever before. The <b>3G
mobile phone network</b> uses a different frequency band than
its predecessors to deliver improved and faster data transfer
rates. The high speed data capacity enables more content to be
sent to and from mobile handsets through calls, messaging and
internet based content. This high-speed data capacity enables
more content to be sent to and from mobile handsets through
calls, messaging and internet-based content. For example, 3G
phones can be used for video phone calls, video message bank,
internet and email, real-time interactive gaming and media
streaming, such as news, weather and dedicated TV shows. While buying mobile phones at online mobile shops, you can great
deals on 3G mobile phones and lots of benefits like free line
rental, half line rental, free mobile phone insurance, etc. The
3G network brings the world of the internet to a mobile phone
with the addition of enhanced messaging and multimedia
functions. With 3G, standard phone features are enhanced with
video calls, video message bank and multimedia messaging. Users
have the facility to make video calls to other users with a
compatible handset and network. 3G mobile phones can send and
receive email as well as browse the internet. The improved data
transfer rates of 3G means that multimedia and mobile has come
alive. These handsets can be used to play back music, movie
