Optical fiber-based distributed antenna systems, components, and related methods for monitoring and configuring thereof
First Claim
1. A wireless communication system, comprising:
- communication components, comprising;
a downlink base transceiver station (BTS) interface configured to receive downlink electrical radio frequency (RF) signals from at least one BTS on at least one communication downlink;
at least one optical interface module (OIM) configured to;
receive and convert the downlink electrical RF signals from the downlink BTS interface into downlink Radio-over-Fiber (RoF) signals on the at least one communication downlink; and
receive and convert uplink RoF signals from at least one remote antenna unit (RAU) into uplink electrical RF signals on at least one communication uplink;
an uplink BTS interface configured to receive and communicate the uplink electrical RF signals from the at least one communication uplink to the at least one BTS; and
a controller configured to predict the failure of at least one of the communications components based on receiving alarm information from at least one of the communication components defining at least one condition indicative of a predictive failure in the at least one of the communication components, and to calculate the alarm for the at least one of the communication components.

Abstract
Optical fiber-based wireless systems and related components and methods support radio frequency (RF) communications with clients over optical fiber, including Radio-over-Fiber (RoF) communications. The systems may be provided as part of an indoor distributed antenna system (IDAS) to provide wireless communication services to clients inside a building or other facility. The communications can be distributed between a head end unit (HEU) that receives carrier signals from one or more service or carrier providers and converts the signals to RoF signals for distribution over optical fibers to end points, which may be remote antenna units (RAUs). A microprocessor-based control system or systems may also be employed. The control systems may include one or more microprocessors or microcontrollers in one or more of the components of the system that execute software instructions to control the various components and provide various features for the optical fiber-based distributed antenna systems.
