Patent number: 9538388Abstract: 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: August 14, 2009Date of Patent: January 3, 2017Assignee: Shared Spectrum CompanyInventors: Mark Allen McHenry, Igor Anatoly Bazarov, Jevgenijs Livsics, Filip Perich, Olga K. Ritterbush, Karl N. Steadman

Patent number: 8767556Abstract: 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: May 2, 2012Date of Patent: July 1, 2014Assignee: Shared Spectrum CompanyInventors: Dmitry Dain, Igor Bazarov, Jevgenijs Livsics, Mark McHenry

Publication number: 20130273957Abstract: 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: ApplicationFiled: June 10, 2013Publication date: October 17, 2013Inventors: Mark Allen McHenry, Dmitry Dain, Jevgenijs Livsics, Karl Steadman, Olga Ritterbush
