FlexWave® Prism Digital DAS

Large venue digital DAS with CPRI donor interface

The FlexWave Prism is a flexible, scalable, complete solution for addressing the coverage and capacity needs of large venue wireless networks. The industry's first combination of distributed antenna system (DAS) and remote radio head (RRH) products, Prism improves wireless network coverage and capacity by extending services from existing cell sites to hard-to-reach areas by distributing coverage from a centralized radio suite.

Prism features an optional dual-port CPRI digital interface unit (CDIU) that provides an efficient wireless delivery solution for high-capacity, multicarrier DAS. The CDIU integrates the Nokia AirScale baseband unit (BBU) with the CommScope Prism DAS portfolio for significant cost, space and power efficiencies.
