Claim of US Patent No. 9,137,132

1. An antenna monitoring system configured to monitor a distributed antenna system, comprising:
a plurality of analog-to-digital (A/D) converters configured to receive a corresponding plurality of tapped Radio Frequency
(RF) antenna signals from a plurality of antenna sub-systems comprising the distributed antenna system and generate a plurality
of RF digitized antenna signals from the plurality of A/D converters; and

an antenna monitor coupled to the plurality of A/D converters and coupled to a Base Transceiver Station (BTS) of the distributed
antenna system, with the antenna monitor comprising:

a storage system configured to store an antenna monitor routine and a plurality of per-antenna information;
a communication transceiver configured to transfer the plurality of per-antenna information to the BTS; and
a processing system coupled to the storage system and the communication transceiver, with the processing system configured
to receive the plurality of RF digitized antenna signals from the plurality of A/D converters, reverse-process the plurality
of RF digitized antenna signals to generate the plurality of per-antenna information, and feed the plurality of per-antenna
information to the BTS, with the BTS using the plurality of per-antenna information to monitor the plurality of antenna sub-systems.
