Abstract
Antenna monitoring modules associated with antennas and test antennas communicating test signals, input blocking modules, and addressable mixed signal processors determining antenna performance. Distributed antenna systems including global transceivers, splitters or tappers, monitoring modules, antennas and test antennas, that monitor antenna presence and performance indications, and centrally report antenna status. Distributed antenna systems including a trunk, multiple coupled branch runs with corresponding antenna monitoring modules, antennas and switches, capable of selectively decoupling antennas. Distributed antenna systems with programmable attenuators for adjusting transmission levels for a trunk and its segments, branches, and corresponding antennas. Distributed antenna systems for over the air antenna transmission and reception testing using local or global signals. Distributed antenna systems with a system controller selectively depowering and repowering segments thereof. Distributed antenna systems with switches coupled to an antenna monitoring module by multiple selectable routes. Distributed antenna systems with loop-based antenna configurations supplying power in mul…
