Local power management for remote antenna units in distributed antenna systems
First Claim
1. A remote antenna unit (RAU) for a distributed antenna system, comprising:
- at least one power-consuming RAU module comprising a radio frequency (RF) communications module having at least one antenna configured to provide RF communications services to a coverage area;
at least one powered port configured to provide power to at least one external power-consuming device connected to the at least one powered port; and
a controller configured to;
determine an available power budget for the at least one powered port; and
enable power for the at least one powered port if the available power budget is sufficient to power the at least one external power-consuming device connected to the at least one powered port.

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

17. A computer-readable medium storing one or more programs, the one or more programs comprising instructions, which when executed by a controller in a remote antenna unit (RAU) in a distributed antenna system, cause the controller to:
-
determine an available power budget for at least one powered port in at least one RAU provided in a distributed antenna system, the RAU configured to provide power to at least one external power-consuming device connected to the at least one powered port based on power required by at least one power-consuming RAU module; and enable power for the at least one powered port if an available power budget is sufficient to power the at least one external power-consuming device connected to the at least one powered port, wherein the instructions are configured to cause the controller to disable the at least one powered port if the available power budget is not sufficient to power the at least one external power-consuming device connected to the at least one powered port. - View Dependent Claims (18, 19, 20)
