Abstract: Networked sleep mode management is provided by measuring network conditions for a first Access Point (AP) serving a plurality of Client Devices (CDs) configured to operate in one of a sleep mode and an active mode; in response to detecting, based on the measured network conditions, an amount of network usage devoted to transitioning members of the plurality of CDs from the sleep mode to the active mode satisfies a threshold: identifying a first subset of CDs from the plurality of CDs that are deprioritized for access to the sleep mode; receiving a sleep request from a given CD that is a member of the first subset of CDs; and denying the sleep request to force the given CD to maintain the active mode for at least a predefined amount of time.

Abstract: Techniques are disclosed for determining, at a first wireless access point (AP), one or more radio resource management (RRM) input parameters. The one or more RRM input parameters are determined based on a line of sight (LOS) estimate between two wireless stations (STAs). A plurality of RRM values are generated based on the one or more RRM input parameters. A wireless connection is established between the first AP and a first STA using the RRM values.

Abstract: In one embodiment, a method is performed. A first wireless access point (AP) device may generate a timing synchronization frame. The timing synchronization frame may include a target beacon transmission time (TBTT) associated with the first wireless AP device. The first wireless AP device may transmit the timing synchronization frame to a second wireless AP device. The first and second wireless AP devices may be synchronized using the timing synchronization frame.

Abstract: A flexible radio assignment algorithm that reduces co-channel interference in Wi-Fi networks is disclosed. The flexible radio assignment algorithm calculates a density value for each of the APs controlled by a network controller. The flexible radio assignment algorithm selects an AP with the highest density value and determines that a radio in the selected AP is redundant. The flexible radio assignment algorithm manages the redundant radio in the selected AP to mitigate co-channel interference in a frequency band.
