RF shielding parameters incorporated into iBwave DESIGN

Owings Mills, Maryland, March 30, 2016_Signals Defense today announced availability of its RF shielding products for application in buildings being outfitted with a distributed antenna system (DAS) or small cells to improve in-building wireless (IBW) performance.

The RF shielding products, led by innovative DAS Shield™, can be applied as a film to windows in an existing building or as custom-made windows for new construction.

“This is a game changer for in-building wireless systems,” said Todd Gardner, Signals Defense President.

“With proper application, DAS Shield creates what we call an ‘RF Predictable’ environment inside buildings. This means that in-building wireless systems can be designed and deployed without having to go through a lengthy process to test and adjust signal levels at the indoor antennas to overcome signal encroachments and interference from nearby macrocells. At the same time, there is no interference at the macrocell from the in-building system. Consequently, DAS and small cell deployment and testing time and associated costs can be reduced substantially in large installations.”

He added, “RF shielding products have been used for some time in security and government applications. We are offering the first commercially-available products developed for in-building wireless applications. Our products are “purpose-built” to attenuate RF signals across the 100 MHz to 12 GHz range by an average 30 dB, depending on the frequency. This is a great advantage over repurposed products that have incidental and unpredictable RF properties at a couple of random frequencies. This range spans public safety, TV white space, cellular and Wi-Fi applications.”

Signals Defense’ IBW products include DAS Shield™, SD-1000/1010 and SD-2500/2510 each with different performance characteristics that meet specific site requirements.

RF performance specifications for DAS Shield™ already are incorporated in iBwave® Design in drop-down menus so that system planners can model in heat maps the ‘Before’ and ‘After’ effects of applying the RF shielding in the RF design phase.
