Publication number: 20130028181Abstract: A system for managing parallel processing of network packets is also provided. A wireless access device that includes multiple transceivers and multiple processing units receives network packets. A media access controller determines which transceiver a received network packet is associated with. A tagging module determines whether the transceiver associated with the received network packet is bound to one of the processing units. In response to a determination that the transceiver is bound, a scheduler assigns the received packet to the processing unit the transceiver is bound to. In response to a determination that the transceiver is not bound, the tagging module binds the transceiver to a processing unit such that the processing unit processes network packets associated with the transceiver while the transceiver is bound to the processing unit, and the scheduler assigns the received network packet to the processing unit the transceiver is bound to.Type: ApplicationFiled: December 20, 2011Publication date: January 31, 2013Applicant: Xirrus, Inc.Inventor: David B. Rosen

Patent number: 8116697Abstract: Systems and methods are provided for reducing multi-modulation radio transmit range. The method comprises determining a data modulation type at which a transmitter is operating, and adjusting a transmitter power according to the data modulation type to control transmit range. Each data modulation type may be determined to operate at a designated transmit power level by determining each data modulation type and arranging in order of a data connection rate corresponding to each data modulation type. For each data modulation type, the difference between a minimum signal-to-noise ratio (SNR) at the connection rate and a minimum SNR at the next higher connection rate is calculated. Starting with the lowest data connection rate and at the maximum transmit power, the transmitter power levels are calculated for each data connection rate such that the transmitter range is limited and operation at the highest data connection rate is permitted.Type: GrantFiled: November 13, 2007Date of Patent: February 14, 2012Assignee: Xirrus, Inc.Inventors: Dirk Gates, Kirk Matthews, Kurt Sauter

Patent number: 8112039Abstract: A system and method for providing radar signal detection in a communications system. In an example method, a raw energy detect signal is received and analyzed to determine if the raw energy detect signal contains a valid radar pulse. A bit is stored in a bit sequence storage device such that the bit has a first value if a valid radar pulse was detected or a second value indicating that a valid pulse was not detected. A set of bits in the bit sequence storage device are accessed to determine if a plurality of waveform-indicating locations in the bit sequence storage device includes valid pulses. In another aspect of the invention, a system detects a radar signal in a communications device. The system includes a pulse detector to detect pulses in a raw energy signal having a pulse width within a predetermined minimum and maximum pulse width. The system includes a frequency detector having a bit sequence storage device to store the bits output by the pulse detector.Type: GrantFiled: December 11, 2007Date of Patent: February 7, 2012Assignee: Xirrus, Inc.Inventor: Drew Bertagna
