Patent number: 10932138Abstract: Improved techniques are provided for managing and optimizing network resources and spectrum access in a Self-Organizing Network (SON). A Spectrum Access System (SAS) collects network-related information from a plurality of network sources, such as base stations and user equipments (UEs), to perform optimization and organization across different networks, network operators, and network technologies. In some embodiments, the SAS may use the network information and a Radio Environment Map to optimize TDD synchronization in the SON. In other embodiments, the SAS may use the network information to populate a global Neighbor Relation Table. The SAS also may use the network information to optimize one or more network parameters, such as Physical Cell Identities or Root Sequence Indexes, antenna parameters, transmit power levels, handover thresholds, channel assignments, and so on, for use in the SON.Type: GrantFiled: April 6, 2017Date of Patent: February 23, 2021Assignee: Federated Wireless, Inc.Inventors: Samuel Jay MacMullan, Deepak Das, Osama Tarraf, Pirouz Zarrinkhat

Publication number: 20200359229Abstract: Techniques are provided for managing frequency access in a shared spectrum available to a radio local access network (RLAN) in a wireless network. A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contours; storing the plurality of I/N contours in a database; receiving, from an RLAN device in the wireless network, a request for spectrum availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for spectrum availability, an I/N contour from the database matching RLAN parameters; determining, based on the extracted I/N contour, available frequency information corresponding to the received request for spectrum availability; and transmitting, to the RLAN device, the available frequency information.Type: ApplicationFiled: May 5, 2020Publication date: November 12, 2020Applicant: Federated Wireless, Inc.Inventors: Samuel Jay Macmullan, Michael Oliver Ghorbanzadeh, James Ni, Kurt Schaubach

Publication number: 20190387414Abstract: A method and system is provided for enabling spectrum sensing capability in a network having at least one primary user and a plurality of secondary users configured to communicate using a shared spectrum. The methods and systems include receiving values from sensors corresponding to received signal strength from a primary user in one or more frequencies of the shared spectrum. The values are used to interpolate at least one additional value between the sensors. A detection threshold is determined for sensing a signal transmitted from the primary user based on an acceptable amount of interference. The primary user is then determined to be transmitting in the one or more frequencies of the shared spectrum if any of the values received from the plurality of sensors or the at least one additional value interpolated along the path exceeds the detection threshold.Type: ApplicationFiled: August 29, 2019Publication date: December 19, 2019Applicant: Federated Wireless, Inc.Inventors: Samuel Jay MACMULLAN, Sepehr MEHRABANZAD, Peter HARBOUR, Creighton ELDRIDGE

Patent number: 10128898Abstract: An improved technique for detecting the presence or absence of one or more predetermined signals in a shared spectrum. In accordance with the disclosed embodiments, a received RF signal may be down-converted to a baseband signal, which is subsequently processed by a spectrum sensor to detect the presence or absence of a predetermined signal, such as a predetermined radar signal. The spectrum sensor may transform the baseband signal to the frequency domain, for example using a fast Fourier transform, to generate a corresponding set of frequency components. The spectrum sensor multiplies the frequency components of the baseband signal with the frequency response of a matched filter having a set of coefficients corresponding to the predetermined signal. The spectrum sensor may convert the matched-filter output signal to the time domain, for example using an inverse fast Fourier transform, and then may determine a value indicative of the signal power that it compares with a known threshold value.Type: GrantFiled: April 10, 2017Date of Patent: November 13, 2018Assignee: FEDERATED WIRELESS, INC.Inventors: Samuel Jay Macmullan, Etty Lee, Jeff Winston, Rohan Grover, Kurt Schaubach
