As mobile network operators (MNOs) grow more complex and
crowded macro networks, the risk of passive intermodula on
(PIM) grows as well. PIM occurs when two or more wireless
signals mix together and create addi onal frequencies that
cause interference and deteriorate network performance. Some
common causes of PIM are loose metal-to-metal contacts, poor
quality components that rust or corrode, metal shavings or other
site contamina on, nearby frequency sources (power lines/
equipment), or obstacles in the RF path. A major source of PIM
at the top of the tower is the numerous non-RF path accessories
like brackets, hangers, and mounts.
The Hi-Risk PIM zone exists in close proximity to the antenna;
in front, above, below, and even behind it. The zone is defined
as: ten feet directly above or below the antenna, five feet
behind the antenna, and one hundred feet in front of the
antenna. Standard installa on prac ces and products must be
modified within the Hi-Risk zone to avoid PIM. Many tradi onal
installa on products have been iden fied as being PIM
generators and must be eliminated.
Why PIM-guard?
1. Reduces PIM while maximizing structural integrity
2. Provides end-to-end strategy
3. Enables network contractors and installers to improve
the RF efficiency in their customers' evolving and
complex networks
PIM-guard solutions extend CommScope's industry-leading
PIM protection to non-RF path installation accessories.
PIM-guard components, like cable support brackets, hangers,
RRU mou
nts, roof mounts, cable bands, cable es, and tower
adapters, are op mized to reduce PIM while maximizing
structural integrity. From materials selection and corrosion
resistance to the exterior contours and profile, PIM-guard
reflects CommScope's experience and understanding of PIM's
sources and solu ons.
When combined with CommScope's PIM-figh ng RF path
components, PIM-guard accessories provide an end-to-end
strategy, enabling network contractors and installers to
improve the RF efficiency in their customers' evolving and
complex networks.
