from various vendors will provide
the best possible coverage
for situations for likely to be
encountered in real deployments.
One last key item missing from the
TECHNOLOGY FEATURE » WiFi TESTING
WiFi space (until recently) has been
an industry-wide plan for this type
of performance testing. Without
an agreed set of tests and metrics,
device manufacturers were left
to their own devices and claims;
therefore, service providers had to
sort through all of that “data” and
ultimately use it in their selection
processes. This obviously led to
gaps and missed expectations on
device performance. Currently,
the Broadband Forum is in the
final stages of development for
the WT-398 WiFi In-Premises
Performance Test Plan. This
represents the first time the
industry has reached agreements
on performance tests and their
metrics, and will give service
providers a powerful tool in
evaluating WiFi devices from
different manufacturers. Assuming
service providers require devices
to pass these requirements before
deployment, WiFi should keep up
with the internet demands for the
next couple of years.
>> Roman Buff,
Market Manager Aerospace,
By pushing electrical shielding
requirements up, it’s led
us to design and develop
highly shielded products.
We address the increasing
requirements with a line of five
shielded cables, which increase the effectiveness
for our product line of highly shielded pre-
terminated aerospace cable assemblies, from 90
dB to 120 dB over the complete frequency range
without decreasing the electric performance.
The cable-connector junction is the weak point
of a cable assembly, which is highly dependent
on workmanship and cable braid construction.
Therefore, these cables are only available as pre-terminated cable assemblies to guarantee cutting-edge shielding effectiveness.
For connector interfaces and board-to-board PCB
connections, we’re offering dedicated shielding
effectiveness engineering support, by simulating the
electrical field distribution of complete RF paths
along with optimizing PCB footprints. In addition,
the connector design is also shielded to minimize RF
leakage of the connector and PCB interface.
