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. Host dynamically allocates capacity amongst RAUs based on current capacity usage.
