electromagnetic war is raging, and the battlefield is the 570-800 MHz frequency
range. That’s because both cellular LTE and service providers use these bands
for their signals—two great connectivity empires on a collision course. Whenever
you have multiple signals occupying the same frequency bands, you run the risk
of signal interference that can greatly impede one or both services.
providers, the threat of signal interference is most prevalent in the last
hundred feet; that is, at the drop cable connection from the utility pole to
the subscriber’s residence. To keep the electromagnetic peace, service
providers need to employ shielded cable that keeps external LTE signals out and
contains the cable television (CATV) signals.
Raise the Shields!
shielding involves layers of super-thin aluminum foil and layers of braided aluminum,
increasing its effective surface area. Simply put, these layers attenuate any
signal seeping in or out of the cable. What’s not so simple, however, is the
variety of engineering options available—and the trade-offs that come with
levels can range from 60 to 90 percent. Additional layers improve interference
resistance, but make the cable more prone to damage when flexed and also
complicate connectorization—two issues that arise regularly in the last hundred
feet. The ideal shielding solution is found in the sweet spot between density
of this optimal balance is what led CommScope to develop XpressPrep drop cables, featuring a 77 percent
tri-shield design. This allows three times the industry standard for
flexibility while also providing superior cable and
connector interference resistance.
in the 570-800 MHz band may rage for years. It only makes sense to employ a
solid defense built on XpressPrep. You can learn more by downloading the “The Impact of Cellular Deployment on
MSO networks at Lower Frequency Bands” white paper.
