    Abstract: Techniques are provided to improve the performance of wireless devices that serve wireless client devices in a wireless network in the presence of narrowband interference. The wireless device that serves wireless client devices in the wireless network receives energy in a plurality of channels of a frequency band. The received energy is analyzed for occurrence and type of interference in each channel. A quality metric is generated for each channel incorporating the occurrence and type of interference detected in the channel. For each channel, a bias value against selection of the channel is assigned based on whether narrowband interference is present in the channel. The bias value for each channel is applied to the quality metric for the channel to produce an adjusted quality metric for each channel. A channel is selected based on the adjusted quality metric for each of the plurality of channels.

    Abstract: At a plurality of first devices, wireless transmissions are received at different locations in a region where multiple target devices may be emitting. Identifier data associated with reception of emissions from target devices at multiple first devices is generated. Similar identifier data associated with received emissions at multiple first devices are grouped together into a cluster record that potentially represents the same target device detected by multiple first devices. Data is stored that represents a plurality of cluster records from identifier data associated with received emissions made over time by multiple first devices. The cluster records are analyzed over time to correlate detections of target devices across multiple first devices.

    Abstract: Techniques are provided for receiving a transmitted first packet that was formatted using a known scrambling algorithm with an unknown scrambling seed. An encoded packet payload is extracted from the first packet header. The encoded packet payload header is decoded to obtain a first scrambled packet payload header. For each potential value of the unknown seed, the first scrambled packet payload header is descrambled to produce a first set of descrambled packet payload headers and for each potential value of initial register values associated with a cyclic redundancy check, the cyclic redundancy check is executed comprising polynomial division on each of the descrambled packet payload headers such that when the polynomial division results in a zero remainder, a potential unscrambled payload header for the first packet is obtained. Information about the first packet is obtained from the potential unscrambled payload header.

    Abstract: A system for managing return channel bandwidth in a two-way satellite communication network is disclosed. A plurality of transceivers are configured to transmit backlog information over a return channel via a satellite. The backlog information specifies an amount of queued traffic for the respective transceivers. A hub is configured to receive the backlog information and to allocate a predetermined amount of return channel bandwidth to each of the plurality of transceivers. The hub determines whether additional return channel bandwidth is available to accommodate a remaining backlog such that a bandwidth allocation amount is set to a level associated with one of the plurality of transceivers having the largest backlog. The hub selectively identifies a transceiver among the plurality of transceivers having a next largest backlog based upon the determined available return channel bandwidth. The hub selectively adjusts the bandwidth allocation amount to a level associated with the transceiver with the next largest backlog. The hub allocates the additional return channel bandwidth to the plurality of transceivers based upon the adjusted bandwidth allocation amount if the adjusted bandwidth allocation amount reduces at least a portion of the backlog of the plurality of transceivers.

    Abstract: Wider bandwidth transmissions are dynamically enabled in a wireless networking environment. During a transmit opportunity time interval for a wireless network device, a transmission is sent in a primary channel in a frequency band in which the primary channel and a secondary channel may be used simultaneously to send a wider bandwidth transmission. Activity is monitored in the secondary channel. A determination is made as to whether the secondary channel is free based on the monitoring. When it is determined that the secondary channel is free, the wider bandwidth transmission is sent in the primary and secondary channels.

    Abstract: Techniques are provided to adaptively adjust a clear channel assessment threshold for use when a wireless device is to transmit in a wireless network that operates on a channel in a radio frequency band. A first wireless device, configured to wirelessly communicate with one or more second wireless device in the wireless network, receives energy on the channel in the frequency band, analyzes the received energy to detect interference on the channel and determines a type of interference detected in the received energy. The clear channel assessment threshold is adjusted by an amount depending on the type of interference detected.

    Abstract: A spectrum analysis engine (SAGE) that comprises a spectrum analyzer component, a signal detector component, a universal signal synchronizer component and a snapshot buffer component. The spectrum analyzer component generates data representing a real-time spectrogram of a bandwidth of radio frequency (RF) spectrum. The signal detector detects signal pulses in the frequency band and outputs pulse event information entries output, which include the start time, duration, power, center frequency and bandwidth of each detected pulse. The signal detector also provides pulse trigger outputs which may be used to enable/disable the collection of information by the spectrum analyzer and the snapshot buffer components. An alternative pulse detection module is provided that tracks signal pulses by comparing peak data from successive FFT cycles with existing signal pulse data that is derived from comparing peak data for prior FFT cycles. Peaks for new FFT cycles are matched to data associated with signal pulses determined to be occurring over many FFT intervals.
