Passive intermodulation (PIM) continues to be one of the top causes of
quality and performance issues faced by wireless operators in their
networks. In 2011, CommScope’s
Andrew Solutions is targeting PIM in an all-out assault.
PIM is the result of two or more wireless signals mixing together to
create additional, undesired frequencies that cause interference or
degrade transmission of desired signals in wireless networks.
Recognizing that conquering PIM requires a broad and comprehensive
approach, Andrew Solutions, the CommScope, Inc. division that is a
global leader in wireless communication systems and products, has
introduced a new five-level PIM program—“PIM
Happens, Just Not on Our Watch”—for the wireless industry.
“RF engineers are aware of PIM, but may not fully appreciate the degree
of damage it causes to a wireless network, lumping PIM together with
other performance metrics,” said Stan Catey, senior vice president and
general manager, Cable Products, Andrew Solutions. “That is why our new
‘PIM Happens, Just Not on Our Watch’ campaign includes educating
engineers, operators and installers in addition to a variety of
prevention and resolution techniques.”
The destructive effect of PIM on wireless networks typically manifests
as shrunken cell coverage area, dropped calls, data transmission rate
slow downs, and degraded quality of service. Effectively managing PIM
requires a holistic approach because it can be caused by a multitude of
sources—improper component installation, poor network optimization,
testing errors, and more. Operators who successfully mitigate PIM should
realize optimized channel capacity, increased quality of service,
targeted and less costly resolutions, and improved time to market.
Andrew Solutions’ “PIM Happens, Just Not on Our Watch” program is based
on five approaches—awareness, prevention, identification, resolution,
and support—for addressing PIM’s capacity to degrade wireless network
Awareness – Andrew Solutions has created multiple tools—including a
PIM and VSWR calculator, FAQ, and testing guidelines—to increase
knowledge about PIM. These tools are available to customers under the PIM
Support section of the Support
tab on www.commscope.com.
Prevention – Andrew
Institute®, Andrew Solutions’ installer training organization, is
now offering a PIM
Fundamentals course with curriculum designed to promote best
practices for minimizing PIM during site installations.
Identification – CommScope’s Field Engineering Services team can help
pinpoint sources of PIM thanks to experienced field personnel with
knowledge about proper PIM testing techniques.
Resolution – Once non-compliant network components are identified,
they can be replaced using the PIM-qualified Rapid Response Product
Support – The Intermod Squad™ Technical Support team now offers
24-hours a day support and technical assistance for issues regarding
PIM. They can be reached at 1-800-255-1479 or email@example.com.
“Our concerted PIM campaign is in response to an ongoing issue facing
the wireless industry,” said Paul Bell, senior vice president and
general manager, Base Station Antenna and Microwave Products, Andrew
Solutions. “These training and troubleshooting tools can help remedy
today’s PIM issues and avoid future ones.”
CommScope’s Andrew Solutions is now offering its comprehensive PIM
Happens program to North American customers. For more information, visit
