TWO MAIN TECHNOLOGICAL TRENDS OF
TODAY:





MOBILE COMMUNICATIONS





INTERNET


Interestingly, mobile subscribers are increasingly demanding

Internet access while on the move and at increasingly high speeds;

thereby resulting in the Convergence of the above two technological

trends

leading

to

the

birth

of

“Mobile

Broadband”

(application)


and

(enablers

of

this

application)


Paradigm shift
-

Internet goes Mobile

Statistics at a glance
:


(i)
Global Mobile Subscriber growth has been phenomenal from
zero levels in
1992

to cross the landline’s billion by 2002 and the climb to
2.68 billion by
Dec. 2006


(ii) The global mobile phone market is set to grow to 4
-

4.5 billion by 2011
fuelled by strong demand from developing economies in Asia and Latin
America.

(iii) 61% of the world’s mobile subscribers are in developing countries. China and
India together added almost 200 million mobile subscribers to the global total
in the first three months of this year.


(iv) Almost 1 billion handsets sold in the year 2006.


(v) 1 billion internet users by Dec. 06.


(vi) 275 million broadband connections.


(vii) Around 2010, data traffic likely to exceed voice traffic.


All the above point to a remarkable development that is changing the world and
the way be communicate!

EVOLUTION OF MOBILE SYSTEMS




Pre Cellular



e.g. IMTS (Improved Mobile Telephone System)




Analog FM System used in mid 1960s.




1G
-

e.g. AMPS, TACS, ETACS, NMT


Partially digital, used


from early 1980s in 800 MHz
-
900 MHz bands.




2G


e.g. IS 95, GSM


Fully digital, used from early 1990s,


in bands 800, 900, 1700, 1800 and 1900 MHz, Voice Centric


with limited data capabilities and SMS.




3G


e.g. CDMA 2000, WCDMA


Supporting voice plus high


speed packet data services.




4G
-

Fixed Mobile Convergence; Seamless Mobility; very high


data speeds






PARADIGM SHIFT


In 1G

-

emphasis was on technology, in particular on the evolution



of network infra
-
structure to address the New World of




mobility.


In 2G

-

manufacturers were striving to meet consumer demand for


ever smaller phones with longer battery life and advanced


features.


In 3G

-

focus will now be on content and multimedia applications.



Voice telephony will be complemented by services beyond



voice.



In 4G
-

‘service and experience’

3G Partnership Projects


Two partnership projects have been established to
accelerate all aspects of 3G standardization







Main thrust of each project is to find commonality for their
respective standards across regions


Global harmonization could enable:


lower overall costs


faster product cycles


faster operator implementation of 3G services

4 G



As the first implementations of 3G are beginning
to roll out, the shortcomings of 3G networks are already
being discussed and the scientists/researchers have begun
to talk of 4G (also referred to as ‘IMT
-
Advanced’ by
ITU) which, at this initial stages, implies
“improvement
and the fixing of lingering 3G problems, apart from
increasing data speeds beyond 2 Mbps”.



Systems beyond IMT
-
2000 are commonly referred
to as the Fourth Generation Networks (4G) or Beyond 3G
(B3G) or IMT Advanced.






4G Vision



There will not be a single network branded as 4G in the same
way that there is 2G GSM or 3G UTRAN. Instead, 4G will be
a collection of networks and a wide variety of smart devices
communicating with each other.



The 4G technology will provide for a collection of different
kinds of multiple access networks in which a user can gain
access to a portal on the Internet (or whatever the entity) by the
most appropriate means.



The user will not have to know which network provides the
service. The smart device can analyze its environment and
choose the best available service provider and technology
(service discovery)
.




Co
ntd….



Contd…..


Both the network entities and the smart devices will be able to
configure themselves so that they can adapt to new requirements.


The emergence of fourth generation of mobile services will allow

Users to connect to different networks depending on their location.

For example, a handset could connect a wireless local area network

(WLAN) when inside a building, switch to a 3G mast when outside,

And connect to a standard network in areas with no 3G coverage.


4G is supposed to be an all IP Network with higher bit rates,
enhanced Multimedia services, smooth streaming videos, worldwide

Access/roaming capability, Intelligent software as driven technique.

OFDM
-
UWB (Orthogonal Frequency Division Multiplexing
-
Ultra

Wide Band) as representative standard, FDMA, TDMA, CDMA as

Multi access techniques, low cost and tight security network.

Key takeaways



-

Mobile has become the dominant means for accessing


communications particularly in developing countries
.

(The “1 billion” figure of global mobile subscriber base was reached (in 2002)
-
some 23 years after NTT DoCoMo launched the first Cellular System in 1979,
whereas the next 500 million mark was reached (in 2004)

just after 2 years
and the “2 billion” figure was reached in 2005).


-
Mobile networks are fast moving towards “All IP” networks.


-
There is a shift in the wireless business model from a


technology and device driven world to a service
-
and


experience
-
centred world.

-
The debate of wired Vs wireless will end in the NGN era


through Fixed Mobile Convergence (FMC).


-

FMC will combine the convenience, freedom of movement and


personalised services of the wireless world with the high quality


and speed of fixed communication.
