    摘要: A method and system of optimizing transmit beam forming in a multiple radio wireless system is provided. A stimulus signal can be provided to an analog receive input of a device under test (DUT), wherein the DUT includes multiple radios. A receive phase and amplitude can be measured at baseband using the stimulus signal for each radio. At this point, a receive weight and its conjugate can be determined using the receive phases and amplitudes. A calibration vector and its conjugate can also be determined, wherein a product of the receive weight conjugate and the calibration vector conjugate generate a transmit weight. This transmit weight can be applied to transmit signals during the transmit beam forming using the multiple radios.

    摘要: A wireless local area network (WLAN) system can have multiple antennas to improve signal detection and decoding. A WLAN receiver in such a system includes multiple amplifiers that can appropriately size an incoming signal and an automatic gain control unit to process the received incoming signals. The amplifiers of a chain of the WLAN receiver, i.e. an antenna and associated receiver components, can be adjusted with computed gains. To optimize the wireless system detection and decoding, the automatic gain control unit can advantageously compute these gains for each amplifier in the WLAN receiver.

    摘要: An audio/video (AV) processor is coupled to a media access controller (MAC) to generate a composite packet having an optimized format for carrying audio, video, and data traffic with fields in a header of the composite packet specifying video-specific information. A physical device interface (PHY) is coupled to the MAC. The PHY encodes and decodes between a digital signal and a modulated analog signal. The PHY comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). A radio frequency (RF) transmitter is coupled to the PHY to transmit data.

    摘要: A system and method are described for binding together a plurality of wireless data communications channels, whereby an aggregate throughput improvement is realized. A master channel amongst the channels to be bound is compatible with existing standards-based wireless data communications equipment. The master channel serves to perform MAC association and flow control. Aggregate throughput is improved by sending and receiving either multiple sets of separately encoded packets, commonly encoded packets or redundantly encoded packets.

    摘要: Transmission monitoring can be used to determine the optimum data rate for a channel. The transmission monitoring can include sending data packets in the channel using various data rates. At least some data packets are sent using the current optimum data rate, a rate lower than the current optimum data rate, and a rate higher than the current optimum data rate. One of these data rates can be selected as the new optimum data rate. In one embodiment, if the current optimum data rate is less than a predetermined data rate, then the client is triggered to begin scanning for other available access points.
