Abstract: An access point configured to be implemented in a wireless network, the access point including a beacon module and a transmit module. The access point is configured to communicate with one or more client stations in the wireless network. The beacon module is configured to generate (i) a first beacon and (ii) a second beacon, wherein the first beacon is shorter in duration than the second beacon. The transmit module is configured to periodically transmit, to the one or more client stations in the wireless network, each of the first beacon and the second beacon. Each time the first beacon and the second beacon are transmitted by the transmit module, the first beacon is transmitted prior to the second beacon.

Abstract: A wireless network device including, in the wireless network device, a Bluetooth device and a wireless local area network device. The Bluetooth device is configured to establish a network of Bluetooth client stations and output a synchronization signal prior to a start of Bluetooth data transmission between the Bluetooth device and the Bluetooth client stations. The synchronization signal indicates the start of the Bluetooth data transmission. The wireless local area network device is configured to establish a network of wireless local area network client stations, receive the synchronization signal from the Bluetooth device, and transmit, a predetermined time subsequent to receiving the synchronization signal, a beacon to the wireless local area network client stations. The beacon instructs the wireless local area network client stations when to begin wireless local area network data transmission.

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 translation: 公开了一种用于减少无线设备中的无线信号接收机消耗的功率量的系统和方法。 接收的数据从接收器传送到与媒体播出设备通信的播放缓冲器。 当接收数据被写入缓冲器时，播放缓冲器中数据的电平增加，并且当从缓冲器读取数据时，数据级别减小。 如果数据级别高于第一水印级别，则在从缓冲器读取数据的同时，接收器被转换到睡眠模式。 当缓冲器中的数据级别低于第二水印级别时，接收器被转换回到活动模式以接收数据。 设备将发送设备的状态消息（无论接收者是睡眠还是活动）传送到发送设备，以便当接收机处于睡眠模式时发送设备停止发送数据，并且当接收机处于活动模式时发送数据。

Abstract: A system including a diversity module and an antenna selection module. The diversity module is configured to measure (i) a first signal-to-noise ratio and a first error rate associated with a first antenna, and (ii) a second signal-to-noise ratio and a second error rate associated with a second antenna. The antenna selection module is configured to select the first antenna or the second antenna by comparing (i) the first signal-to-noise ratio to the second signal-to-noise ratio, and (ii) the first error rate to the second error rate.
