Abstract: A network interface including a radio frequency system with a component configured for communication with an access point. First, second and third client modules communicate with the access point according to respective wireless communication standards. The first, second and third client modules share the component, such that during respective periods the first, second and third client modules communicate with the access point via the component. The first client module transmits a request signal to the second client module while the second client module is in an idle state and the third client module is in an active state. The request signal requests access to the component. The third client module, in response to the request signal, aborts transmitting of first data to the access point and transmits an acknowledgement signal. The first client module transmits to or receives from the access point second data based on the acknowledgement signal.

Abstract: An integrated circuit including a transceiver module that receives beacons from an access point (AP), and transition a wireless network device to an active mode based on: a predetermined beacon interval; and a first predetermined period prior to one of multiple beacons. A timestamp module calculates a first correction value based on a first timestamp received from the AP. An adjustment module adjusts the first predetermined period based on the first correction value. A beacon module detects a beacon missed during an inactive mode by the transceiver module. The timestamp module transmits a probe request signal to the AP a second predetermined period after detection of the missed beacon, receives a second timestamp from the AP in response to the probe request signal, and recalculates the first correction value based on the second timestamp. The adjustment module adjusts the first predetermined period based on the recalculated first correction value.
