Patent number: 9001764Abstract: A channel allocation system for allocating channels in a frequency band to a plurality of radios in close proximity so as to minimize co-channel interference. One method for allocating channels involves initially tuning each of the plurality of radios to the same one of the plurality of channels. All of the radios then receive signals from whatever sources and a signal score is determined for each radio. The radios are then tuned to another one of the plurality of channels. The steps of receiving a signal and determining a signal score for each radio are repeated for each of the remaining channels until all channels have been used. The signal scores are then tested against a table of mapping schemes to determine maximum isolation.Type: GrantFiled: December 31, 2012Date of Patent: April 7, 2015Assignee: Xirrus, Inc.Inventors: Dirk Ion Gates, James Kirk Mathews

Patent number: 8995344Abstract: A wireless network access device comprising a radio interface with a serial communication line, a switch, and M serial connections to M connectors for connecting up to M corresponding detachable radio modules. The radio interface forms up to M individually addressable radio communications paths. Each radio module includes a radio configured to communicate with client devices in a coverage area and a radio processor configured to manage at least one radio receiving buffer. The radio receiving buffers store receiver buffer identifiers to corresponding received data space. A processor manages communication between the client devices that communicate with the radio modules and a data network via the radio interface and a network interface when N?M radio modules are connected to the radio interface. An assist engine is connected in the serial connection between the processor and the switch to manage allocation of receive buffer identifiers to the radio modules.Type: GrantFiled: October 8, 2012Date of Patent: March 31, 2015Assignee: Xirrus, Inc.Inventors: Drew Bertagna, David Rosen

Patent number: 8830854Abstract: 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: GrantFiled: December 20, 2011Date of Patent: September 9, 2014Assignee: Xirrus, Inc.Inventor: David B.
