Abstract: A communication system includes master host unit, hybrid expansion unit, and remote antenna unit. Master host unit communicates analog signals with service provider interfaces. Master host unit and hybrid expansion unit communicate N-bit words of digitized spectrum over communication link. Hybrid expansion unit converts between N-bit words and analog spectrum. Hybrid expansion unit and remote antenna unit communicate analog spectrum over analog communication medium. Remote antenna unit transmits and receives wireless signals over air interfaces. Master host unit includes master clock distribution unit that generates digital master reference clock signal. Master host unit communicates digital master reference clock signal over communication link. Hybrid expansion unit receives digital master reference clock signal from master host unit over communication link and generates analog reference clock signal based on digital master reference clock signal. Hybrid expansion unit sends, and remote antenna unit receives, analog reference clock signal across analog communication medium.

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.
