Connections,
corrugations and
costs—the feeder
cable debate
Singapore is hosting the concurrent
CommunicAsia and BroadcastAsia
exhibitions in june.
Focus on Asia
in June 2004
As a new generation of data-rich RF
technologies arrives in Asia, the demands
placed on wireless infrastructure are
greater than ever. Providing future-proof
RF solutions to meet these demands will be
the focus of Radio Frequency Systems
when exhibiting at both CommunicAsia
and BroadcastAsia 2004—the two major
communications expos for the Asia
Pacific region being held concurrently in
Singapore this June.
At the CommunicAsia exhibition, RFS will
showcase RF solutions that offer both
enhanced network performance and
flexibility for mobile operators. “Recent
W-CDMA [wideband code division
multiple access] and CDMA2000 1X
deployments in Hong Kong, Australia,
Japan and Indonesia, coupled with
planned trials of third generation (3G)
technologies elsewhere in the Asia
Pacific region, are illustrating the need for
dynamic coverage and capacity,” said Peter
Walters, Area Marketing Manager for
RFS. “Add to that the optimization
requirements of maturing 2G networks,
and network operators are faced with an
interesting cocktail of challenges.”
To help meet these challenges, Communic
Asia will see the Asian launch of RFS’s
portfolio of cellular antenna line products
developed in accordance with the
open standard of the Antenna Interface
Standards Group (AISG). This will be
complemented by a complete range of
advanced RFS Optimizer antennas, feeder
systems and in-building products, suitable
for use with all key wireless frequencies.
The Asia Pacific broadcast sector consists of
a similar mix of current and next
generation technologies—with China,
Malaysia, Korea and Japan facing the
immediate challenge of deploying digital
television, while others are involved in
ongoing network expansion projects. “At
BroadcastAsia we will focus on talking to
the broadcasters from these diverse
markets,” said Walters. “By understanding
their specific needs, we can work with
them to develop the most practical
solutions—on a case by case basis.”

IN TOUCH
The ubiquitous coaxial feeder cable
forms the critical link within RF base
stations the world over. Much has
been written and spoken about the wide
range of feeder design architectures on
offer, the performance factors they exhibit
and the design objectives targeted.
While the science and theory of feeder
technology is important, the true bottom
line in the feeder cable debate usually
comes down to practical field performance—particularly
during installation—
and the total life-cycle cost of the feeder
itself.
In the next issue of STAY CONNECTED, we
explore the practicalities of the modern
coaxial feeder cable via those who
know best—the field installers, system
integrators, network operators and cable
designers. Issues such as feeder cable
connection technique, tooling, feeder
routing and bending, crush resistance and
long-term feeder maintenance and
fault-finding will be explored.
