ASIA
: Andrew Corporation will install the world’s first third generation
(3G) wireless network of its kind for use in a public transportation
system under a two-year contract to upgrade the Hong Kong mass transit
railway’s underground communications network.
The distributed
communications system that Andrew is installing into the MTR, Hong
Kong’s metro system, will enable passengers with mobile wireless
devices to enjoy access to advanced multimedia and information services,
such as gaming and real-time streaming video, in addition to traditional
voice calling and text messaging services. This 3G ready network will
be the first in a public transportation system based on the Universal
Mobile Telecommunications System (UMTS) standard. The UMTS standard
was developed to support 3G technology and is most commonly used in
Europe and Asia.
“Andrew
is proud of its role in helping the MTR become the first mass transit
system to provide UMTS-based mobile communications services to its
passengers,” said Bob Hudzik, president, Wireless Innovations
Group, Andrew Corporation. “MTR passengers can pass time by
surfing the Internet or watching streaming video while business people
can take part in video phone calls and receive high-volume emails.
Passengers will benefit from Andrew’s deep experience in working
with transit systems around the world.”
Andrew’s
3G experts engineered the Hong Kong system to address the unique requirements
of a 3G network’s high frequency ranges. Andrew’s design
will counteract signal losses and provide better coverage throughout
the Metro through use of high-performance tuned radiating cables,
large diameter feeder cables, new and relocated antennas at critical
signal sites, new amplifiers and reconfigured transmission paths.
The Andrew system will encompass all underground stations and tunnels
in five MTR lines and the Airport Express. Completion of the entire
project including maintenance is expected in 2006.
The equipment
Andrew will supply, install, test, and commission includes:
3G-compliant
radio frequency and optical amplifiers
Node M43 repeaters
EOCell™ RF-over-fiber system
RCT7-CPUS series tuned RADIAX® radiating cable
HELIAX® foam coaxial cable, connectors and accessories
3G/2G crossband combiner
3G combiners and
Splitters and couplers
The new
3G network continues Andrew’s work with the MTR. In 1994, Andrew
installed the 2LCX integrated radio network to provide GSM, CDMA,
and TDMA services. Andrew also installed the paging facilities system
in 1994 and has maintained both systems since then.
