Abstract: A system and method are disclosed for decreasing the amount of power consumed by a data transmitter in a wireless device when transmitting media (audio and/or visual) data or other data received from a media source or other source. A transmission circuit, such as an application specific integrated circuit (ASIC) or WLAN chip, is configured to deactivate the data transmitter for a deactivation interval and aggregate the media data (or other consistent-rate data) in a buffer while the data transmitter is deactivated. At the end of the deactivation interval, the data transmitter is activated and the aggregated data packets are transmitted. The data transmitter may be repetitively deactivated and activated for transmitting the data. The deactivation interval may be based on the data sampling rate, the transmission rate of the data transmitter, the capacity of the buffer, and/or other factors.

Abstract: A device previously configured as a registrar and that has established an independent ad-hoc network is automatically discovered by another device also previously configured as a registrar. To form an ad-hoc wireless network between these two devices, each device periodically enters a scanning mode to scan for and intercept beacons transmitted by the other device. Upon such interception, one of the devices becomes an enrollee in accordance with a predefined condition and in response to a user selected option. Subsequently, the enrollee modifies its beacons to include an attribute, such as the MAC address, associated with the other device. After intercepting the modified beacon, the remaining registrar prompts it user to decide whether to allow the enrollee to join the registrar's network. If the user responds affirmatively, a handshake is performed between the two devices and a subsequent attempt is made by the enrollee to join the registrar's network.

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 decreasing the amount of power consumed by a wireless signal receiver in a wireless device. Received data is communicated from the receiver to a play-out buffer in communication with a media play-out device. The level of data in the play-out buffer increases when received data is written to the buffer, and the level of data decreases when data is read from the buffer. If the level of data is above a first watermark level, the receiver is transitioned to a sleep mode while data is read from the buffer. When the level of data in the buffer falls below a second watermark level, the receiver is transitioned back to an active mode to receive data. The device communicates status messages (whether the receiver is asleep or active) to the transmitting device so that the transmitting device stops transmitting data when the receiver is in sleep mode, and transmits data when the receiver is in the active mode.

Abstract: An apparatus for transmitting N packets including a key mixing circuit to generate N groups of encryption seeds, each based upon a predetermined key, a transmitter address, and a predetermined start value for a packet number. A packet number circuit inserts a different one of N values for the packet number into each of the N packets. Each of the N values for the packet number is greater than, or equal to, the predetermined start value for the packet number. An encryption circuit encrypts each of the N packets using the one of the N groups of encryption seeds that was generated based on the value for the packet number in the respective one of the N packets. An output circuit sends the N packets. The encryption circuit generates each of the N groups of encryption seeds before an input circuit receives the respective one of the N packets.
