As the success of the Indian
telecom growth has now
become a world story, new
technologies are offering
significant opportunities to take
this industry to the next level.
Significant amongst these is the
third generation mobile
communication technology, more
popularly known as 3G. The
marriage of computers, Internet
and connectivity is here to stay
and with more applications and
business now running on Internet,
the demand for bandwidth and
speed is ever growing. As the
networks or connectivity becomes
more important, than ever before,
computers and Internet have come
to depend upon the network and
connectivity service providers
more than ever before. The 3G
technology is promising to offer
the next wave of significant
boost for both Internet and
mobile applications.
With over 200 companies
across the world deploying 3G
telecom services, it will be the next
big opportunity for growth for the
telecom industry, as the trends and
applications are emerging.With
many of them in Asia, the markets
in Asia Pacific offer the biggest
opportunity. While all three parties
– the network operators, the
vendors and the third party
content developers have jumped
into the fray to create the business
applications on 3G. The question
however remains – Is 3G a hype or
happening? The protagonists are
all pouring their dollars and
betting big time while the critics
are yet to join the bandwagon.
What is 3G?
3G is the next generation of mobile
communication technology,
offering a wide range of high
speed mobile services, including
video calling and messaging, email,
games, photo messaging and
information services. It is the
mobile phone technology standard
supporting simultaneous transfer
of both voice data (a telephone
call) and non-voice data (such as
downloading information,
exchanging email, and instant
messaging). 3G mobile network
is the systems and services based
on the International
Telecommunication Union
(ITU) family of standards under
the International Mobile
Telecommunications programme,
‘IMT-2000’. 3G promises increased
bandwidth, up to 384 Kbps when a
device is stationary or moving at
pedestrian speed, 128 Kbps in a
car, and 2 Mbps in fixed
applications. 3G will work over
wireless air interfaces such as GSM,
TDMA and CDMA. The new EDGE
air interface has been developed
specifically to meet the bandwidth
needs of 3G. 3G uses 5 MHz
channel carrier width to deliver
significantly higher data rates and
increased capacity compared with
current 2G networks and includes
capabilities and features such as
Enhanced multimedia (voice, data,
video and remote control), multi
platform usages such as cellular
telephone, e-mail, paging, fax,
videoconferencing,Web browsing)
and Broad bandwidth and high
speed upwards of 2 Mbps. Speed is
an important aspect which
differentiates this technology –
the speed of 2G is 10 kbps, 2.5G
is 64–144 kbps and for 3G is
144 kbps–2 mbps.
The mobile telephone
companies use systems that are
circuit-switched and hence the
connectivity depends upon
