■
Overview
A comprehensive, coordinated range of coaxial accessories is
offered for flexible combination and installation of the individual
IWLAN components indoors and outdoors.
This range encompasses connecting cables as well as diverse
connectors, lightning protection elements, a power splitter and
an attenuator.
■
Benefits
•
Flexible use thanks to extensive, coordinated range
•
Operation also outdoors with extended temperature range
and protection against water and dust thanks to degree of
protection IP65
•
Components are suitable for use with SCALANCE W700
including national approvals
■
Application
RCoax/antenna connecting cables
•
The flexible IWLAN RCoax/antenna connecting cables are
required for connecting RCoax segments or antennas with
active devices.
•
The cables offer low attenuation so that the quality of the radio
signal is only reduced to a minimal extent.
•
All antenna cables are flame-resistant, chemical-resistant and
silicone-free.
Terminating resistors
•
Terminating resistors are required for wireless termination of
unused antenna connections at the access points and clients.
•
RCoax segments must be terminated at the end with a termi-
nating resistor.
Lightning protection elements
•
When separate antennas are used outdoors, there is a risk of
lightning strikes.
•
A lightning protector can be used to prevent damage.
Cabinet feedthroughs
Together with the antenna connecting cables, the cabinet
feedthroughs enable simple connection of remote antennas to
the active components located in the control cabinet/box.
Attenuator
The 10
dB attenuator is always used when the transmitted power
has to be reduced both in the send and receive directions. Typ-
ical application areas include short RCoax segments or direc-
tional wireless links, which are to be limited in extent.
Power splitter
•
With the help of the power splitter, the transmission power of
an access point is divided between two RCoax or antenna
segments.
•
This enables wireless coverage in two areas using just one
access point.
