O ver the past 10 years, it was CDMA that played the leading role in nurturing,
growing and consolidating the Korean telecommunications industry. Now the
baton has been handed over to WCDMA. The conversion from CDMA to WCDMA
means more than a simple shift of technology from synchronous to asynchronous. Many
other sectors including communication equipment, wireless Internet, terminals, wireless
devices and content as well as telecommunications operators also need to change with the
advent of the new service. To put it another way, a domino effect is taking place whereby
changes in one field influence other areas as well.
The Ministry of Information and Communication reckons that nationwide rollout of
WCDMA/HSDPA will create a new ripple effect worth around 8 trillion won. It must
sound really tempting to the industry, which has suffered from market stagnation. For
example, telecommunications service providers may be able to increase revenue per
subscriber by delivering new add-on services, although it would be difficult actually to
secure more subscribers, since current numbers stand at 40 million. Indeed, this market
would never have been created if they had stuck to the existing CDMA service. Also, a
change is looming in the three-way competition between SKT, KTF and LGT, not least
because KTF has recently become a leader in the changes by taking the offensive, which
has never been witnessed in the past. During the process of change, some positives will
also result, such as increased competition and reduced prices.
A new opportunity has also opened up to the equipment and terminal markets, which have
had no new pull factors since the release of camera phones. The same is true for the
content industry. For their part, CPs (content providers), so far dependent on the 3 mobile
operators, have also been handed a new business opportunity of their own, with the advent
of full browsing. Above all, the greatest significance of WCDMA is that real market
competition has been triggered. Leaping the barrier of CDMA and arriving in the global
market, the mobile operators are about to contend for victory, for which they need to be
aware that WCDMA is going to stimulate further future culture shifts.
It is still not certain that video calling is going to be 3G’s killer application. Nevertheless, the
remarkable increase in the volume of data able to be transmitted at any one time takes on
huge importance. Through this technological advance, the telecommunication industry will
more actively be able to reflect the trend of personalization - for example UCC (User Created
Content) - and how to respond to this trend will be key to future competition. Next-generation
services befitting 3G will have to be developed in line with cultural changes initiated by
a combination of end users, mobile communication operators and new technology. Sunbae Kim KIICA President
