This digital distributed antenna system (D-DAS) solution features unique, patented technology that distributes wireless coverage digitally over optical fiber, enabling InterReach ICS to deliver superior signal quality, flexibility, and overall performance. Its digitized optical RF transport also future-proofs in-building wireless infrastructure for higher data rate services. The InterReach product family offers service providers a flexible, scalable, all-digital platform to improve customer retention and offer enhanced services to meet increasing subscriber demands. Features • Highlyscalablesolutionfeatureselementsthat can be daisy-chained to accommodate large installations; elements also can be added when coverage extension is required. • Configure-to-order,plug-intransceiverdesign lowers initial installation costs and allows pay-as-you-grow approach to indoor coverage. •Accommodatesbothsingle-modeandmulti-mode fiber for maximum utilization of existing fiber and flexibility in fiber distribution. • Digitaltransportmaintainssuperiorsignalquality even over long distance fiber runs. • Flexibledesignsupportstechnologiessuchas free space optics (FSO), wave division multiplexing (WDM), etc. • Highdynamicrangeincreasescapabilityfor data throughput, enabling higher data rate broadband services. •Universalairinterfaceistransparenttomodulation technology. InterReach® In-building Coverage Solution 800 ESMR, 850 Cellular, 1900 PCS InterReach® ICS – ADC's Digital Advantage for Improving Wireless Capacity and Coverage The InterReach In-building Coverage Solution (ICS) is used to extend wireless coverage to specific areas within a building, multiple buildings, or throughout a campus environment.

Providing seamless coverage everywhere can be challenging, particularly inside buildings. Carriers implement indoor coverage solutions to increase customer acquisition and retention. A key explanation subscribers give for switching carriers is unsatisfactory network quality. Most often, the highest value subscribers are business users. Providing indoor coverage at business locations can improve subscriber satisfaction, extend service contracts and prevent costly churn. There is clearly an opportunity for wireless service providers to improve profitability by creating a superior network that includes indoor coverage. Nowhere else are mobile voice and data users able to so closely scrutinize the quality of their providers network performance. The onset of higher speed data services requires service providers to design their networks differently, resulting in an increased priority for indoor coverage. Data users often use their mobile devices within office buildings and will not tolerate dropped calls or inadequate service for transfers of data. In addition, third generation services will result in smaller cell sizes, causing the macro network coverage to be insufficient for thoroughly penetrating buildings, particularly new construction materials with high RF attenuation properties. A dedicated indoor coverage solution can improve macro network coverage because it offloads capacity from the macro network. In-building needs are everywhere, including corporate campuses, traffic corridors such as tunnels and subways, coverage holes, capacity hotspots, and public spaces such as airports, hospitals, government c...
