Abstract: Power management for remote units in a wireless distribution system. Power can be managed for a remote unit configured to power modules and devices that may require more power to operate than power available to the remote unit. For example, the remote unit may be configured to include power-consuming remote unit modules to provide communication services. As another example, the remote unit may be configured to provide power through powered ports in the remote unit to power-consuming devices. Depending on the configuration of the remote unit, the power-consuming remote unit modules and/or power-consuming devices may demand more power than is available at the remote unit. In this instance, the power available at the remote unit can be distributed to the power-consuming modules and devices based on the priority of services desired to be provided by the remote unit.

Abstract: Optical network units (ONUs) for high bandwidth connectivity, and related components and methods are disclosed. A fiber optical network ends at an ONU, which may communicate with a subscriber unit wirelessly at an extremely high frequency avoiding the need to bury cable on the property of the subscriber. In one embodiment, an optical network unit (ONU) is provided. The ONU comprises a fiber interface configured to communicate with a fiber network. The ONU further comprises an optical/electrical converter configured to receive optical downlink signals at a first frequency from the fiber network through the fiber interface and convert the optical downlink signals to electrical downlink signals. The ONU further comprises electrical circuitry configured to frequency convert electrical downlink signals to extremely high frequency (EHF) downlink signals at an EHF, and a wireless transceiver configured to transmit the EHF downlink signals to a proximate subscriber unit through an antenna.

Abstract: Distributed antenna systems provide location information for client devices communicating with remote antenna units. The location information can be used to determine the location of the client devices relative to the remote antenna unit(s) with which the client devices are communicating. A location processing unit (LPU) includes a control system configured to receive uplink radio frequency (RF) signals communicated by client devices and determines the signal strengths of the uplink RF signals. The control system also determines which antenna unit is receiving uplink RF signals from the device having the greatest signal strength.

Abstract: Fiber optic array cables and related systems and methods to determine and/or track locations of objects are disclosed. The fiber optic array cables can be employed in an optical-fiber-based communication system, including a centralized optical-fiber based communication system. In one embodiment, the fiber optic array cable is configured to carry optical RF or radio-over-fiber (RoF) signals to establish communications with objects. The fiber optic array cable includes multiple reference units along the length of the cable. The reference units can be configured to convert received optical RF signals into electrical RF signals to establish RF communications with objects capable of receiving electrical RF signals. The reference units are also configured to convert received electrical RF signals from the objects into optical RF signals, which are then used to determine the location of the object. Having the availability of the multiple reference units on one or more the fiber optic array cables can provide enhanced reliability in tracking objects.

Abstract: Optical fiber-based wireless systems and related components and methods are disclosed. The systems 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 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). In one embodiment, calibration of communication downlinks and communication uplinks is performed to compensate for signal strength losses in the system.

Abstract: Components, systems, and methods for determining propagation delay of communications in distributed antenna systems are disclosed. The propagation delay of communications signals distributed in the distributed antenna systems is determined. If desired, the propagation delay(s) can be determined on a per remote antenna unit basis for the distributed antenna systems. The propagation delay(s) can provided by the distributed antenna systems to a network or other system to be taken into consideration for communications services or operations that are based on communications signal delay. As another non-limiting example, propagation delay can be determined and controlled for each remote antenna unit to uniquely distinguish the remote antenna units. In this manner, the location of a client device communicating with a remote antenna unit can be determined within the communication range of the remote antenna unit.

Abstract: A switched wireless system is used to increase the range of peer-to-peer communications. The optically-switched fiber optic communication system includes a head-end unit (HEU) having a switch bank. Cables couple the HEU to one or more remote access points in different coverage areas. The switch bank in the HEU provides a link between the remote access points in the different coverage areas such that devices in the different cellular coverage areas communicate with each other, such as through videoconferencing. By using the switched communication system, the range and coverage of communication between devices may be extended such that devices in different coverage areas and devices using different communication protocols can communicate.
