Wideband-Wireless
Local Loop System (W/WLL)
 LG
Information and Communication Co., Ltd.
(LGIC) has announced the development
of its Wideband-Wireless Local Loop
System (W-WLL). This wireless subscriber
system economically offers voice and
high-speed data service at a quality
equivalent to existing wire-based services.
The development of W-WLL involved a
number of major technologies. They included
V5.2 network interface, wireless protocol,
voice compression, RP/RIU management,
RF and RPOM remote software down loading
technology. LGIC succeeded in the development
and commercialization of W-CDMA ASICS
(the core technology of W-WLL) that
can provide wireless data transmission
eight times faster than N-CDMA,
and twice as fast as IMT-2000. It also
established a world first by the commercialization
of wireless packet data technology that
maximizes the rate of data transmission
within a restricted wireless resource.
LGIC's packet technology can
be used for both domestic and international
applications. The unique wireless packet
data algorithm developed by LGIC is
considered ideal for middle-sized and
large cities that have huge demand
for fast Internet service. Only a small
number of companies have succeeded in
commercializing a W-CDMA based WLL system.
LGIC's W-WLL system is the first in
the world to be based on a commercial-level
fast wireless packet data technology.
Despite its lower cost of initial
investment than those for wired systems,
the quality of transmission is the equivalent
or better. Accordingly, the market outlook
for W-WLL is considered to be bright.

Virtual
CD-ROM Drives
 Space
International Inc. has unveiled new
software under the name of CDSpace.
It enables users to run CD programs
without inserting them into a CD-ROM
drive. It does this by creating a virtual
CD-ROM drive on the hard disk space
using new technologies. This emulator
allows users to run CD-ROM applications
even from the network server. With CDSpace,
it is possible to establish and access
up to 23 different virtual CD-ROM drives
on your hard drive space. CDSpace encompasses
high-tech programming techniques, which
by creating image files of contents
in CD-ROM titles (games or other application
programs) and storing them in the hard
drive, makes it possible to run programs
up to 200 times faster than in conventional
physical CD-ROM drives. In fact, it
could be said that CDSpace is an unprecedented
new genre of CD-ROM emulation application
technology. A CD-ROM image is created
using the finest compression technique
on the hard drive (or network file server)
and a new virtual CD-ROM is added to
the system.

Plasma-treated
Heat Exchanger
 LG
Electronics has developed a heat exchanger
that resists aging because of
a novel form of plasma treatment. This
globally unique heat exchanger guarantees
permanent operation of air conditioners
by removing water from the surface of
heat exchangers, the key culprit that
causes malfunctioning, noise and premature
aging. The LG Electronics heat exchanger
will thus greatly improve long-term
air conditioner performance and reliability.
Humidity in the air inevitably
results in condensation on the
surface of heat exchangers, and the
moisture thus created should be effectively
removed to reduce noise and operate
more efficiently. Air conditioner makers
worldwide have tried to overcome this
problem by developing paints that facilitate
rapid water run-off. However, this type
of technology has a definite limitation,
namely aging;a heat exchanger's surface
unavoidably deteriorates over time.
The new technology has a totally
different approach for solving this
problem. Instead of applying paint,
it chemically changes the aluminum surfaces
of a heat exchanger by using an elaborate
plasma treatment. The treatment also
guarantees high durability throughout
the life of the air conditioner. The
chemically changed surface does
not easily deteriorate over time, because
the plasma-treated layer is so firmly
bound and chemically stable. Therefore,
the heat exchanger is rendered totally
impervious to water, since it is impossible
to dissolve the functional layer. This
plasma treatment technique is expected
to find a range of applications in surface
engineering fields such as boiling and
condensation, frosting/defrosting, hydrophobic
modification and anti-corrosion measures.
