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.

Abstract: A method for measuring downlink delay in a radio system includes applying a digital representation of a Gaussian pulse to a digital interface of the radio system; marking the digital representation of the Gaussian pulse with respect to a frame of digital data with a marker; propagating the Gaussian pulse in the radio system to an antenna, the radio system configured to convert the digital representation of the Gaussian pulse to a radio frequency signal transmitted at the antenna; measuring when the Gaussian pulse occurs in the radio frequency signal based on the marker; and determining a downlink propagation delay for the radio system between application of the digital representation of the Gaussian pulse at the digital interface and transmission of the radio frequency signal at the antenna.
