Abstract: A wireless network interface generates a beacon frame, and transmits the beacon frame outside of a wireless local area network (WLAN) served by an access point (AP). Additionally or alternatively, the wireless network interface receives a first probe request frame from a client station in the WLAN, and in response, generates and transmits a probe response frame outside of the WLAN. The wireless network interface receives one or more frames from the client station of the WLAN, the one or more frames having been transmitted outside of the WLAN. Network security information corresponding to the WLAN is extracted from the one or more frames, and the wireless network interface uses the network security information to wirelessly connect to the AP as part of the WLAN.

Abstract: A filter expression is received at a wireless device assembly of a communication device. While a host assembly of the communication device is in a sleep mode, the wireless device assembly receives a signal having packet data, and determines whether the packet data contains a data pattern indicated by the filter expression. If the packet data contains the data pattern, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. If the packet data does not contain the data pattern, the wireless device assembly does not communicate the wakeup signal to the host assembly.

The method comprises transmitting or receiving a signal by a station in the ad hoc wireless network during a beacon interval. The station enters a power saving doze state immediately following the transmission or reception of the signal and prior to the end of the beacon interval. Additionally or alternatively, the station may enter power saving doze state following a timed period, according to a counter, or according to a periodic pattern.

Abstract: In a method and apparatus for providing memory efficient filtering of a received broadcast signal, a wireless device assembly compares a filter expression to packet data in the broadcast signal to determine whether the packet data contains a particular bit pattern indicated by the filter expression. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. If the host assembly is in a sleep mode, and if the packet data contains the particular bit pattern indicated by the filter expression, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. On the other hand, if the packet data does not contain the particular bit pattern indicated by the filter expression, the wireless device assembly does not communicate the wakeup signal to the host assembly.

Abstract: Methods, systems and computer program products are described for transferring aggregated data packets over an I/O interface from a host to a multiport embedded device. For example, a method includes receiving, by the device from the host, a single write command that (i) specifies two or more ports from among multiple ports of the device, and (ii) includes two or more data packets to be respectively written to the specified ports. The multiple ports of the device are mapped to corresponding locations of memory of the device. The method further includes saving, by the device in response to the single write command, the two or more data packets at two or more memory locations to which the specified ports are mapped. Additionally, the method includes sending, upon saving the data packets, a single notification to the host indicating that the device is ready to receive another write command.
