Patent number: 10104555Abstract: Systems and methods for configuring a network of radios for dynamic spectrum access are described. A network radio can include hardware and/or software modules for detecting a radio environment and negotiating common communications channels with a plurality of other radios in the network. Network radio behavior can be defined by a plurality of predefined policies which are used in combination with the information about the radio environment to select common operating parameters.Type: GrantFiled: June 16, 2014Date of Patent: October 16, 2018Assignee: Shared Spectrum CompanyInventors: Dmitry Dain, Igor Bazarov, Eugene Livis, Mark Allen McHenry

Patent number: 10070437Abstract: Methods for using a detector to monitor and detect channel occupancy are disclosed. The detector resides on a station within a network using a framed format having a periodic time structure. When non-cooperative transmissions are detected by the network, the detector assesses the availability of a backup channel enabling migration of the network. The backup channel serves to allow the network to migrate transparently when the current channel becomes unavailable. The backup channel, however, could be occupied by another network that results in the migrating network interfering with the network already using the backup channel. Thus, the detector detects active transmission sources on the backup channel to determine whether the backup channel is occupied. Methods for using the detector include scheduling detection intervals asynchronously. The asynchronous detection uses offsets from a reference point within a frame.Type: GrantFiled: October 19, 2016Date of Patent: September 4, 2018Assignee: Shared Spectrum CompanyInventors: Mark Allen McHenry, Dmitry Dain, Eugene Livis, Karl Steadman, Olga Ritterbush

Patent number: 9900782Abstract: Methods and systems for dynamic spectrum access (DSA) in a wireless network are provided. A DSA-enabled device may sense spectrum use in a region and, based on the detected spectrum use, select one or more communication channels for use. The devices also may detect one or more other DSA-enabled devices with which they can form DSA networks. A DSA network may monitor spectrum use by cooperative and non-cooperative devices, to dynamically select one or more channels to use for communication while avoiding or reducing interference with other devices.Type: GrantFiled: December 21, 2016Date of Patent: February 20, 2018Assignee: Shared Spectrum CompanyInventors: Mark Allen McHenry, Igor Anatoly Bazarov, Eugene Livis, Filip Perich, Olga K.

Patent number: 9854461Abstract: A method for classifying a signal can be used by a station or stations within a network to classify the signal as non-cooperative (NC) or a target signal. The method performs classification over channels within a frequency spectrum. The percentage of power above a first threshold is computed for a channel. Based on the percentage, a signal is classified as a narrowband signal. If the percentage indicates the absence of a narrowband signal, then a lower second threshold is applied to confirm the absence according to the percentage of power above the second threshold. The signal is classified as a narrowband signal or pre-classified as a wideband signal based on the percentage. Pre-classified wideband signals are classified as a wideband NC signal or target signal using spectrum masks.Type: GrantFiled: July 9, 2014Date of Patent: December 26, 2017Assignee: Shared Spectrum CompanyInventors: Eugene Livis, Mark Allen McHenry, Dmitry Dain, Karl Steadman, Olga Ritterbush
