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 wireless device capable of matching a user with content based on the user's proximity to other users, by searching for a match between profiles of wireless devices within a wireless coverage area. Wireless devices broadcast profiles within a wireless coverage area. Other wireless devices within the wireless coverage area receive the broadcasted profiles, determine a match between the received profile and a profile stored on the wireless device, and display a match indicator if a match is determined. In this manner, a user having a wireless device may be matched with content based on the user's proximity to other users.

Abstract: Techniques for establishing a dynamic ad-hoc wireless network are disclosed. A node transitions between wake and sleep modes during periods defined as beacon intervals. Before a network connection is established and while it is awake, the node transmits network connection request and also listens for network activity. If a beacon or response message is not detected while the node is listening, the node enters sleep mode and thereby conserves power. The node optionally changes the duration of its detection period and/or the time at which it listens for network activity relative to the start of each beacon interval. Information elements are optionally included with transmitted beacons or response messages.

Abstract: A system and method are disclosed for controlling transmit power amplification in a wireless transmitting device. A processor receives data to determine whether a communication channel from a transmitting device to a receiving device is strong enough to support a target data transmit rate of the devices with a power amplifier either on or off. The processor controls a switching device between a data transmitter circuit and the transmitter's antenna based on the quality of the communication channel. In a first state, the switching device connects the data transmitter circuit to the power amplifier to increase the strength of the signal communicated to the antenna. In a second state, the switching device bypasses the power amplifier. The power amplifier is turned off when the switch is in the second state, thereby decreasing the power consumed by the transmitting device as it transmits data at the target data transmit rate.

Abstract: An approach for assigning IP network addresses and for performing name resolution and service discovery in infrastructure mode and/or ad-hoc mode peer-to-peer networks. The size of an ad-hoc network and/or the size of infrastructure network basic service sets may be limited to a selected number of peer stations. A first portion of an IP network address assigned to stations joining a network may be predetermined by the network to be joined and a second portion of the IP network address may be selected dynamically, as each new station joins the network. Stations may generate layer 2 messages that include an information element containing information that supports peer-to-peer service discovery, name resolution and IP network address assignment across multiple ad-hoc and infrastructure networks. A peer-to-peer station may dynamically connect to available ad-hoc or infrastructure networks to access required services, as needed.

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 wireless network interface includes a component, a first sub-client module that operates using a first wireless protocol, and a second sub-client module that operates using a second wireless protocol. The first and second wireless protocols are different. The first and second sub-client modules share use of the component. A component sharing control module selectively transitions the first sub-client module into and out of a state to allow the second sub-client module to use the component during the state.

Abstract: A system and method are disclosed for controlling transmit power amplification in a wireless transmitting device. A processor receives data to determine whether a communication channel from a transmitting device to a receiving device is strong enough to support a target data transmit rate of the devices with a power amplifier either on or off. The processor controls a switching device between a data transmitter circuit and the transmitter's antenna based on the quality of the communication channel. In a first state, the switching device connects the data transmitter circuit to the power amplifier to increase the strength of the signal communicated to the antenna. In a second state, the switching device bypasses the power amplifier. The power amplifier is turned off when the switch is in the second state, thereby decreasing the power consumed by the transmitting device as it transmits data at the target data transmit rate.
