Patent number: 9467893Abstract: The present disclosure discloses a system and method for classifying Wi-Fi signals from Fourier transform samples. Generally, classifying Wi-Fi signals from Fourier transform samples includes: collecting and dividing Fourier transform samples into frequency blocks; determining the bandwidth for the Fourier transform sample; and determining whether the Fourier transform sample corresponds to a narrowband signal. Further, if a determination is made that the Fourier transform sample does not correspond to a narrowband signal, channel utilization is calculated based on a determination that the FFT sample corresponds to a Wi-Fi signal. If it is determined that the Fourier transform sample corresponds to a narrowband signal, then a determination is made that the FFT sample corresponds to a Wi-Fi signal based on certain criteria. The certain criteria may include one or more of a slope value, a number of sub-peak bins, an analysis of adjacent channels, characteristic matching, or other criteria.Type: GrantFiled: April 18, 2016Date of Patent: October 11, 2016Assignee: Aruba Networks, Inc.Inventors: Subbu Ponnuswamy, Nethra Muniyappa, Kiranmaye Sirigineni

Patent number: 9456364Abstract: Adapting scanning of frequency channels of different or varying widths to collect wideband spectrum data is disclosed. Scanning methods and/or configurations are modified based upon the type and signal strength of the interferers present or expected in the spectrum. The system includes: selecting a portion for scanning, wherein the portion includes contiguous and non-contiguous segments, partitioning the selected portion into a first plurality of channels, where at least two of the plurality of channels have different widths, each of the first plurality of channels including contiguous or non-contiguous segments; during a first scan of the selected portion, scanning the selected portion of the radio frequency spectrum at least by scanning a first channel with a first width and scanning a second channel with a second width that is different than the first width; and based on the first scan, collecting data representing the selected portion of the radio frequency spectrum.Type: GrantFiled: December 4, 2013Date of Patent: September 27, 2016Assignee: Aruba Networks, Inc.Inventors: Subbu Ponnuswamy, Kiranmaye Sirigineni, Nethra Muniyappa

Patent number: 9438496Abstract: The present disclosure discloses a system and method for monitoring link quality between internetworking devices. The system includes a processor and a memory storing instructions that, when executed, cause the system to: generate, at a first internetworking device, a marker-request packet that includes a current marker ID; send, from the first internetworking device, the marker-request packet to a second internetworking device; receive, at the first internetworking device, a marker-reply packet that responds to the marker-request packet from the second internetworking device, the marker-reply packet including the current marker ID and a previous marker ID; and determine, at the first network device, a link quality between the first internetworking device and the second internetworking device based at least in part on the marker-reply packet.Type: GrantFiled: October 31, 2013Date of Patent: September 6, 2016Assignee: Aruba Networks, Inc.Inventors: Gopalakrishna Raman, Kiranmaye Sirigineni, Neal Castagnoli, Rajini Balay, Scott McGrath
