Abstract: Devices, systems, methods, and processes for orchestrating and managing various lower-power modes in a variety of network devices within a network are described herein. Various network devices, such as access points may be capable of entering one or more lower-power modes of operation that utilize less electricity to operate. When initiating a lower-power mode, the various clients that the network device has been handling need to be handed off to a sibling AP nearby. However, when exiting these lower-power modes, these devices may need different amounts of time to reboot and/or resume normal operations. Thus, when deciding which clients to re-associate with the waking up network device, various considerations need to be weighed based on client needs and network device capabilities. Thus, a smart environmental controller (SEC) is utilized to coordinate these processes. The SEC can be a specialized device, or a logic distributed remotely or among the network devices.

Abstract: Various methods, systems, and/or processes are described herein that can operate on a minimally energized power level to detect motion and paths of motion within an environment. A device suitable for carrying out these operations may include an energization optimization logic which can be responsible for selecting a floorplan, identifying access points associated with the floorplan, determining identities, such as persons, located within the floorplan, and tracking their motion. Once this information is gathered, the logic determines a reduced power configuration and passes it to various access points in the floorplan area to reduce the energy consumption based on the configuration. This allows for energy optimization while still maintaining the tracked motion of the identities within the floorplan. The logic allows for efficient power usage in areas with high traffic flow, while still maintaining the quality of service for the identities within the space, which can change dynamically over time.

Abstract: Various methods, systems, and/or processes are described herein to create more sustainable configurations of wireless Access Points (APs), switches, and other network devices based upon network speed, client demand, among other factors. Clients may wirelessly couple to an AP using a variety of different technologies. The clients may be distributed over these frequency bands in an optimal manner allowing minimum use of transceiver power. The network link speed between the AP and the Ethernet switch may also be dynamically adjusted. These configurations may dynamically change over time as client demand or network traffic increases or decreases. In certain other configurations, the APs may have a higher wireless throughput than the ethernet connections to the network. In these instances, sustainable configurations can be achieved by powering down transceivers, radio chains, and/or processor cores. Traffic and other events may trigger the need for new sustainable configurations to be generated and applied.

Abstract: A method, computer system, and computer program product are provided for dynamic power saving for wireless access points. It is determined that a wireless client has not requested to connect to a first access point for a first threshold duration of time. Power is disabled to one or more front-end modules of a plurality of front-end modules associated with the first access point except for one designated front-end module that remains powered. Monitoring is performed for an incoming request to connect to the first access point. Power is restored to the one or more front-end modules of the plurality of front-end modules.
