  • Patent number: 11057083
    Abstract: Systems and methods are provided for optimizing channel bandwidth while increasing downlink multi-user, multiple-input, multiple-output (DL MU-MIMO) gain. Depending on the access point (AP) platform, for example, APs exhibit certain characteristics regarding DL MU-MIMO gain as a function of the number of DL MU-MIMO clients associated to the AP. Accordingly, APs can be configured to operate in accordance with an algorithm that checks the number of DL MU-MIMO capable clients are associated to an AP, and dynamically switch between single- and dual-radio modes of operation to take advantage of those DL MU-MIMO gains.

  • Patent number: 10924995
    Abstract: This disclosure is directed to controlling a wake-up radio (WUR) in a wireless station side client device (STA-device). In one example, after the STA-device has received negotiation parameters from a wireless access point (AP) to establish a wireless association as a network connection between the STA-device and the AP. The PCR may be disabled in favor of the WUR. The WUR, which may use less power than the PCR, may then monitor for Beacon Frames (e.g., in the disclosed beacon loop) and Discovery Frames (e.g., in the disclosed discovery loop). Based on a state machine, that may be implemented as computer instructions executed by a hardware processor of the STA-device. Generally, the STA-device may use the WUR and state machine implementation to determine a proper time to re-enable the PCR for communication with the AP.

  • Publication number: 20210029642
    Abstract: Examples provided herein describe a method for managing power consumption of a network. For example, a network device may monitor a set of network area zones of a network coverage area, where each network area zone is associated with a set of edge devices. A first occupancy state may be determined for a first network area zone of the set of network area zones based on usage of a first set of edge devices of the first network area zone. Based on the determined first occupancy state, a first power consumption policy for the first network area zone may be determined. Responsive to determining the first power consumption policy, the determined first power consumption policy may be applied to the first set of edge devices in the first network area zone at least edge changing a power consumption mode of a first edge device in the first set of edge devices.
