Aspects of the disclosure relate to a non-coordinated shared spectrum system. One or more processors are configured receive data associated with a notification from a device experiencing interference on an assigned channel. The one or more processors may determine a coverage area of an antenna providing the assigned channel to the device and determine based on the data associated with the notification, available channels within the coverage area of the antenna. The one or more processors may generate a map based on the data associated with the notification, wherein the map indicates the available channels within the coverage area of the antenna.

Assigning frequencies without coordination in a shared spectrum regime

In the presence of a network fault condition preventing communication between a communication device and a network device of a first network, a method includes receiving a heartbeat request from the communication device requesting permission for the communication device to perform a device operation. The method further includes obtaining device state data associated with the communication device and determining whether the communication device is permitted to perform the device operation based on the device state data associated with the communication device. When the communication device is permitted to perform the device operation, the method also includes transmitting a heartbeat confirmation signal to the communication device. The heartbeat confirmation signal permits the communication device to perform the device operation.

Method and apparatus for ensuring continued device operational reliability in cloud-degraded mode

An environmental frequency sensing device, includes logic that performs signal strength (SS) level separation on a received band of frequencies to produce SS level separated frequencies. The logic performs frequency grouping on the SS level separated frequencies for each signal strength level to produce magnitude information for each grouping. The logic generates peak data by detecting peaks of the produced magnitude information. The logic generates an edge event indicating a signal edge based on arrival or departure of a given peak and compares, on a frequency basis, generated edges to stored fingerprint data of a signal of interest. Based on the comparison, the logic provides detected signal data indicating current use of a range of frequencies in an environment.

Featured items of distributed discussion collaboration

Techniques for managing power loads of a data center include electrically coupling a data center infrastructure power load and a data center IT power load in a power distribution system having a specified power capacity, the infrastructure power load including a plurality of infrastructure power loads associated with at least one of a data center cooling system, a data center lighting system, or a data center building management system, and the IT power load including a plurality of IT power loads associated with a plurality of rack-mounted computing devices; determining that a predicted amount of the IT power load is about equal to or greater than a threshold power value; throttling the infrastructure power load to reduce a portion of the power capacity used by the infrastructure power load; and based on throttling the infrastructure power load, increasing another portion of the power capacity available to the IT power load.

Managing power between data center loads

The subject matter of this specification can be embodied in, among other things, a method that includes supplying power to a portion of a data center through a power distribution line. Utilization of a statistically significant sample of the computers is monitored, and an estimated individual power draw for each of the computers based on the utilization is calculated. An estimated total power draw is calculated for different times from the estimated individual power draws to generate a collection of estimated total power draw values for the different times. Actual power draw is monitored at the power distribution line and a collection of actual power draw values is generated. A function is fitted to pairs of actual power draw values and estimated power draw values, each pair comprising an actual draw value and an estimated draw value for the same time, and the function is then stored.

Accurate power allotment

A network switch includes a power connection configured to receive power from a primary power source and at least two ports. At least a first one of the ports is configured to connect to a first network interface of a first computing device through a communication medium configured to conduct operating power for the network switch. The first network interface is configured to draw electrical power from a power supply of the first computing device and provide, through the network cable, at least a portion of the drawn electrical power as the operating power. A switching circuit is configured to route network data between the ports and a power management circuit coupled at least to the first port. The power management circuit is configured to draw at least a portion of the operating power from the first port, and power the switching circuit using the drawn power responsive to a detected failure of the primary power source.

Back-up power for a network switch

A system includes a power-consuming, at least one energy storage device, and a power management system. The facility is configured to receive electrical power from an electric utility grid. The energy storage device is located at the power consuming facility and is configured to store electrical energy from the electrical power received from the electric utility grid. The power management system is configured to receive, from the electric utility grid, a request that indicates an amount of power and, in response to the request, to cause at least a portion of the power-consuming facility to be powered by the at least one energy storage device rather than the power received from the electric utility grid such that an amount of the received power consumed by the power-consuming facility is reduced by at least the indicated amount.

Power-consuming facilities as a source of reserve power

A method and apparatus are provided for balancing the load placed by a data center on different phases of a power input. According to the method and apparatus, the load on the power is monitored and a load imbalance detected. Once the load imbalance is detected, a server rack from the data center is selected and a power supply in the selected server rack is reconfigured to output an increased or decreased voltage.

Active phase balancing at facility level

A distributed uninterruptible power supply provides power to a system including a plurality of electronic computing devices. Each electronic computing device may include an on-board battery to provide power when a power outage occurs. The electronic computing devices that are executing processes that may be temporarily suspended without adversely impacting the processing of a majority of the plurality electronic computing devices may be identified as sacrificial devices. The motherboard of each sacrificial device may be deactivated to suspend any executing processes. The DC power provided by the on-board battery of each sacrificial device may be converted to AC power and then supplied to the non-sacrificial devices.
