Abstract: Systems and techniques relating to management of membership in mobile, wireless ad hoc networks are described. A described technique includes transmitting, by a device that is not a member of an ad hoc network, a request to join the ad hoc network to a given device of the ad hoc network. The method also includes receiving from the given device information including a set of addresses of devices of the ad hoc network that is locally stored at the given device. In addition, the method includes obtaining an address for the requesting device to be different from any address of the received set of addresses.

Abstract: A wireless network bridge controls a first network interface to operate as a first station in a first wireless network, and controls a second network interface to operate as an access point in a second wireless network. The bridge controls a bridge table that includes an entry associating one or more network addresses of a second station with the second network interface. The second station is accessible through the second network interface operating as an access point. The bridge receives a packet for communication between the second station and a network device in the first wireless network; examines the packet to find one or more network addresses included in the packet; associates the packet with the second station by performing a lookup of the bridge table; and communicates packet information with the second station through the second network interface, and with the network device through the first network interface.

Abstract: A communication device using a current wireless network via a first access point confirms availability of a second access point before breaking the current connection. To confirm availability of the second access point, the communication device sends a power management message that causes the first access point to store packets during the power management period. After the connection to the second access point is confirmed, the second session may be put on hold using the same technique while the connection to the first access point is restored, the stored packets processed and the connection closed. Then the connection to the second access point may be reactivated and further communication made through the second access point.

Abstract: A first network interface and a second network interface of a wireless network device are respectively controlled to operate as a station in a first wireless network and as an access point in a second wireless network. A beacon message, which includes a first signal strength of a first bridge node that is an access point in the first wireless network, is transmitted through the second network interface. A probe response message, which includes a second signal strength of a second bridge node that is an access point in a third wireless network, is received at the second network interface. Conditioned on determining that the second signal strength is greater than the first signal strength, the first network interface is disconnected from the first bridge node and is connected to the second bridge node to operate as a station in the third wireless network.

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.

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: A wireless data transceiver includes a media access controller (MAC) that receives an inbound packet from an air interface and to buffer that packet for transport to a host, and receives an outbound packet and transfers that packet to the air interface. A host interface receives the inbound packet from the MAC and transfers the inbound packet to the host, and receives the outbound packet from the host for transfer to the MAC. Transport controller circuitry (TCC), including processing circuitry configured to execute instructions, manages the transceiver. Hardware data transport circuitry (HDTC) for transporting packets in either direction between the MAC and the host interface includes a buffer memory having a plurality of slots. The TCC or HDTC issues a start or stop signal to the host interface causing the HDTC and the host interface to begin or end transfer of data between the buffer memory and the host interface.

Abstract: A wireless data transceiver includes a media access controller (MAC) configured to receive an inbound data packet from an air interface and to buffer the inbound packet for transport to a host, and to receive an outbound data packet from elsewhere in the transceiver and to transfer the outbound packet to the air interface. The transceiver further includes a host interface configured to receive the inbound packet transported from the MAC and to transfer the inbound packet to the host, and to receive the outbound packet from the host for transfer to the MAC. The transceiver also includes transport controller circuitry configured to execute instructions to generate and transfer management packets. In addition, the wireless data transceiver includes hardware data transport circuitry for transporting the inbound packet from the MAC to the host interface, and for transporting the outbound packet from the host interface to the MAC, without executing instructions.

Abstract: The present disclosure describes methods and apparatuses for location service offload for Bluetooth positioning. In some aspects a Bluetooth radio frequency (RF) signal is sampled by a Bluetooth transceiver to produce a set of samples corresponding to an advertisement packet and the set of samples are stored in a shared memory. Another transceiver is signaled that the set of samples are stored in the shared memory, causing the other transceiver to generate the Angle of Arrival (AoA) of the Bluetooth RF signal. A signal is received from the other transceiver indicating that the generated AoA is available in the shared memory. The generated AoA is read from the shared memory by the Bluetooth transceiver and sent to a host processor. By so doing, data transfer between the Bluetooth transceiver and the host processor is reduced, as well as, reducing the computational load on the host processor.
