Patent number: 10321262Abstract: The geo-security method and system uses spatio-temporal radio channel information during authentication to grant permission to access, use and/or operate the intended device. The geo-security method and system uses a wideband radio channel impulse response (or transfer function of radio channel) from antenna of RF source to antenna of a RF receiver at the device position to determine the legitimacy of the intended device's location.Type: GrantFiled: October 5, 2016Date of Patent: June 11, 2019Assignee: Qatar Foundation for Education, Science and Community DevelopmentInventors: Hassan Mohamed El-Sallabi, Mohamed Mahmoud Abdallah, Khalid Ali Qaraqe, Jean-Francois Chamberland, Gregory H.

Patent number: 9844019Abstract: A technique for estimating the location of a wireless terminal at an unknown location in a geographic region is disclosed. The technique is based on the recognition that there are location-dependent traits of electromagnetic signals. In environments where multiple antennas are radiating the same signal, as in the case of distributed antennas or host-repeater configurations, one or more possible locations of the wireless terminal can be designated as improbable based on i) a measure of the propagation delay of a signal traveling between a) a base station and b) the wireless terminal or an infrastructure antenna, or ii) the maximum distance at which a signal is detectable by the wireless terminal. Additionally, the applicable set of values for the location-dependent traits is selected based on similar criteria.Type: GrantFiled: August 12, 2014Date of Patent: December 12, 2017Assignee: Polaris Wireless, Inc.Inventors: Tarun Kumar Bhattacharya, David Stevenson Spain, Jr., Hassan Mohamed El-Sallabi, Robert Lewis Martin

Patent number: 9819081Abstract: The reconfigurable radio direction finder system and method uses a reconfigurable antenna to electronically cycle through a plurality of different antenna configurations to determine a signal direction. Specifically, the reconfigurable antenna is cycled through N different antenna configurations, where N is an integer greater than one, where each antenna configuration has a pointing direction associated therewith defined by an elevation angle ?n of an n-th antenna configuration, where n is an integer between 1 and N, and an azimuthal angle ?n of the n-th antenna configuration. A received signal strength of the radio signal is measured for each of the antenna configurations as a power output of the n-th antenna configuration, Pn.Type: GrantFiled: July 7, 2014Date of Patent: November 14, 2017Assignee: QATAR FOUNDATION FOR EDUCATION, SCIENCE AND COMMINITY DEVELOPMENTInventors: Hassan Mohamed El-Sallabi, Mohamed Mahmoud Abdallah, Khalid Ali Qaraqe, Gregory H.

Patent number: 8532676Abstract: Methods for generating more accurate location estimates are based on indicative factors. The factors are gleaned from wireless signals that were received by a wireless terminal and from other network-specific data. Each factor is probative of whether the wireless signals were received by the wireless terminal: (i) indoors versus outdoors, and/or (ii) “above-the-clutter” versus “below-the-clutter” of ambient wireless signals, and/or (iii) while moving at a certain speed classification, e.g., stationary/pedestrian versus vehicular speeds. Each factor tends to prove or disprove the particular characteristic. The result is an estimated probability, such as the probability that the wireless terminal received the signals indoors. The estimated probability is applied to the analysis of candidate locations, eliminating some candidates from further consideration. This enables computational resources to focus on the remaining higher-likelihood candidate locations and provides improved accuracy in the location estimate.Type: GrantFiled: May 22, 2012Date of Patent: September 10, 2013Assignee: Polaris Wireless, Inc.Inventor: Hassan Mohamed El-Sallabi

Patent number: 8433250Abstract: A method and apparatus for estimating whether or not a wireless terminal is indoors are disclosed. The illustrative embodiment employs a pattern classifier that is trained on a plurality of input/output mappings, where each mapping corresponds to a respective location, the output of the mapping is a Boolean value that indicates whether the location is indoors, and the input of the mapping is based on empirical and predicted signal data for the location. In accordance with the illustrative embodiment, a computer-executable program is generated based on the trained pattern classifier. The computer-executable program estimates whether or not a wireless terminal is indoors based on empirical data reported by the terminal, and on a location estimate for the terminal that might be crude or inaccurate (e.g., based on Cell Identifier [Cell-ID], GPS, etc.).Type: GrantFiled: January 29, 2010Date of Patent: April 30, 2013Assignee: NTT DoCoMo, Inc.Inventors: Tarun Kumar Bhattacharya, Hassan Mohamed El-Sallabi, Scot Douglas Gordon, Yasuhiro Oda, Jiyun Shen
