Abstract: An access point includes a beacon module and a control module. The access point transmits a beacon during a beacon interval. The beacon module determines a first portion of the beacon interval and a second portion of the beacon interval. The access point operates in a normal mode during the first portion of the beacon interval. The control module operates the access point in a power save mode during the second portion of the beacon interval. The control module operates the access point in the power save mode in response to a client station not communicating with the access point during the first portion of the beacon interval.

Abstract: A network interface includes a radio frequency system and a media access controller. The media access controller includes first and second client modules and a control module. Each of the client modules wirelessly communicates with a network via the radio frequency system and the antenna. Each of the client modules is controllable to be in an active state or a sleep state. The control module determines priority levels of the first client module and the second client module. The control module also, based on the priority levels, (i) controls the first client module to be in the active state to permit communication between the first client module and the radio frequency system, and (ii) controls the second client module to be in the sleep state to prevent communication between the second client module and the radio frequency system.

Abstract: A beginning of a Bluetooth inquiry phase or a Bluetooth paging phase is determined. In response to determining that the Bluetooth inquiry phase or the Bluetooth paging phase is beginning, a power save (PS) mode signal is sent from a first device to a second device via a wireless local area network (WLAN) communication link, wherein the PS mode signal indicates that the first device is in a WLAN PS mode. A PS poll signal is sent from the first device to the second device via the WLAN communication link in a gap between Bluetooth inquiry phase message transmissions during the Bluetooth inquiry phase or between Bluetooth paging phase message transmissions during the Bluetooth paging phase.

Abstract: A first message is received that includes a value indicative of a first timeout interval associated with configuring a second device to operate as a peer-to-peer (P2P) group owner or a P2P client in a P2P wireless network. A second timeout interval is determined based at least on the first timeout interval, and it is determined whether the second timeout interval expired. It is determined whether a second message is received from the second device prior to the second timeout interval expiring, and it is determined that a P2P connection with the second device failed based on a determination that the second message was not received from the second device prior to the second timeout interval expiring.
