摘要： A method and apparatus for wirelessly transmitting real-time data streams is described. To ensure continuous data flow, fast diversity and slow diversity can be used. Fast diversity chooses a receive antenna based on received signal parameters, such as signal strength, during the transmission header and prior to information transfer. Slow diversity stores received signal parameters from previous packets, associates the parameters with a selected antenna, and uses the parameter history to denote a “default” antenna. Additionally, receive and/or transmit beam forming can be used to maintain continuous communication between stations. Beam forming, which combines antenna signals to maximize performance, is possible when at least two transmit/receive signal processing chains are available.

摘要： A system and method for closely synchronizing the transmission of real-time data streams is described. Synchronization data is transmitted by a cycle master for receipt by one or more cycle slaves. A cycle slave updates an internal state based on synchronization data received from the cycle master. This internal state may govern reproduction of received real-time data streams by the cycle slave. Such synchronization data may be inserted into transmitted media streams. The cycle slave internal state may be more accurately set by calculating timing differences between the cycle master and cycle slave and periodically adjusting that internal state between receipt of the synchronization data from the cycle master.

摘要： A method of providing synchronization-free station locating in a wireless network is provided. In this method, an AP having a known location sends a unicast packet to the station and notes its time of departure TOD(D). The station receives the unicast packet, notes its time of arrival TOA(D), sends an acknowledgement packet to the AP, and notes its time of departure TOD(D_ACK). The AP receives the acknowledgment packet and notes its time of arrival TOA(D_ACK). Notably, a distance between the AP and the station can be accurately determined using a first difference between the TOA(D_ACK) and the TOD(D) and a second difference between the TOD(D_ACK) and the TOA(D). A plurality of such computed distances between a plurality of APs and the station can be used to determine an accurate location of the station.

摘要： A system includes a bus and a circuit for precharging the bus. The circuit may be coupled to receive a clock signal associated with the bus, and may be configured to precharge a bus during an interval of the period of the clock signal, the interval being between a first edge (rising or falling) and the subsequent edge (falling or rising). A second interval within the period and excluding the interval may be used to perform a bus transfer. In this manner, both precharging and transfer may be performed in the same clock cycle. Bandwidth of the bus may be improved since transfers may occur each clock cycle, rather than having a non-transfer clock cycle for precharging.
