Less Interference, Happier Customers—CommScope Continues to Develop PIM Solutions for Improving Wireless Network Quality
But that is exactly what can happen in extra sensitive LTE networks.
The evolution of wireless networks to LTE brings about increased scrutiny of the performance-degrading phenomenon called passive intermodulation (PIM). PIM is unwanted radio frequency (RF) interference that can result in degraded voice quality, dropped calls and reduced data throughput. The effects of PIM can be significant—for example, just a one decibel drop in uplink sensitivity due to PIM can reduce wireless coverage by 11 percent.
To help operators limit PIM in their networks—whether inside or outside—
The newest additions to CommScope's PIM-avoiding portfolio are the Andrew®
Passive Devices for in-building applications. Every active
distributed antenna system (DAS) is supported by a variety of splitters,
couplers and other passive devices. CommScope's new Andrew Passive
Devices line is a high quality, reliable solution, thoroughly tested for
sources of PIM among other factors, and PIM rated to an industry-leading
-160 dBc. These RF components enable operators to achieve and maintain
effective network performance and support cost-effective business
practices in DAS applications. Andrew Passive Devices can be purchased
from any of CommScope's U.S. distribution partners:

- Andrew® SiteRise™ —This outdoor tower solution is a new way of building tower tops that use remote radio heads close to the antenna. Key to this solution is reducing craft-related installation errors by doing the most complex tasks at the ground level or in a factory, where it is easier to validate results and improve overall quality.
SureFlex® Premium Cable Assemblies with SureGuard™
Weatherproofing—SureFlex assemblies include premium connectors that are physically bonded to the cable using a patented process, eliminating field termination craftsmanship issues and delivering superior PIM performance. Featuring patent-pending SureGuard weatherproofing boots, SureFlex Premium assemblies further protect against common weatherproofing errors that can lead to environmental PIM generators. SureGuard boots are factory installed, significantly decreasing installation time, and are removable and reusable, simplifying site troubleshooting.
"The message about PIM is spreading across the wireless industry, but
its importance is hard to overstate, especially in LTE rollouts," said
