  • Publication number: 20160135184
    Abstract: A distributed antenna system (DAS) includes host that receives downstream signals corresponding to radio frequency (RF) channel and remote antenna units (RAUs) communicatively coupled to host. Host communicates downstream transport signal derived from downstream signals received at host to RAUs. Each RAU uses downstream transport signal to generate downstream RF signal for radiation from antenna associated with RAU. Downstream RF signal comprises a subset of plurality of downstream frequency bands. Each RAU receives upstream RF signal including respective RF channel. Each RAU communicates upstream transport signal derived from upstream RF signal to host. Host uses upstream transport signal to generate upstream signal including at least one upstream frequency band. Host analyzes attribute of downstream and upstream transport signals associated with RAUs, correlates analyzed attribute for each RAU with profile, and determines current capacity usage of RAUs based on correlation.

    Abstract: A communication system to feed remote antenna nodes with simulcast traffic and non-simulcast beacons is provided. The communication system includes a host radio frequency (RF) digitizer, a delay buffer, a summing circuit, and a framer/serializer.
