Publication number: 20240030599Abstract: Embodiments herein describe mounting one or more lasers onto an AP to generate a laser pattern on a surface representing the coverage area of an antenna in the AP. In one embodiment, the antenna is a steerable antenna that can be electronically or mechanical steered to point to different directions (without moving the AP as a whole). The laser or lasers can be used to visualize the coverage area of the steerable antenna when pointing in different directions. Advantageously, a technician can use the laser or lasers to identify a location where, if steered, the antenna would provide the desired coverage area. The technician can then steer the antenna to point in that direction to provide the desired radio frequency (RF) coverage.Type: ApplicationFiled: July 20, 2022Publication date: January 25, 2024Inventors: Fred J. ANDERSON, Jonathan M. CYPHERT, John M. SWARTZ, Daniel N. JOHNSON, Danielle N. BANE

Patent number: 11380991Abstract: An electronically a steerable and switchable antenna array is provided that can produce a first beam with a first coverage range and a second beam with a second coverage range by selecting one of a first and a second beamwidth for both the first and second beams; in response to selecting the first beamwidth: switching signal inputs to narrow-beam antenna arrays; steering the first beam to one of a first positive, negative, or zero offset position; independently steering the second beam to one of a second positive, negative offset, or zero offset position; and transmitting signals received from the signal inputs via the first beam and the second beam; and in response to selecting the second beamwidth: switching signal inputs to wide-beam antenna arrays; and transmitting signals received from the signal inputs via the first beam and the second beam.Type: GrantFiled: April 28, 2021Date of Patent: July 5, 2022Assignee: Cisco Technology, Inc.Inventors: Fred J. Anderson, Danielle N. Bane, John M. Blosco, Paul J. Stager, Daniel N. Johnson, Timothy A. Frank, John M. Swartz

Patent number: 10148002Abstract: The embodiments herein use polarization diversity between antennas where the antennas for one cell are, e.g., horizontally polarized and antennas for the other cell are vertically polarized. In one embodiment, the antennas for a macro cell are vertically polarized while micro cell antennas are horizontally polarized. In one example, the micro cell antennas are printed antennas that form a loop that is co-planar with the magnetic fields generated by the macro cell antennas when transmitting. Because the magnetic fields are co-planar (rather than orthogonal) to the current flowing through the loop in the micro cell antenna, the effect of the electromagnetic signals emitted by the macro cell antenna is reduced. This may permit dual radio network devices to have improved performance when operating simultaneously—e.g., when the macro cell radio is transmitting and the micro cell radio is receiving at or near the same frequency band.Type: GrantFiled: October 18, 2016Date of Patent: December 4, 2018Assignee: Cisco Technology, Inc.Inventors: Erin P. McGough, Daniel N. Johnson, Thomas G. Lutman, Fred J. Anderson

Publication number: 20110078071Abstract: Data representative of a plurality of mortgage applications is obtained. The applications participate in a mortgage origination process, and each of the applications has associated therewith customer-specific attributes and product-specific attributes. The mortgage origination process has a plurality of statuses. Data representative of at least one environmental attribute is also obtained. Each given one of the mortgage applications in a given one of the plurality of statuses at a given time is ranked by likelihood of not closing, based at least on the customer-specific attributes, the product-specific attributes, and the at least one environmental attribute. Those of the mortgage applications likely not to close which are likely not to close due to non-exogenous attributes are identified.Type: ApplicationFiled: September 25, 2009Publication date: March 31, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Chitra Dorai, Jane D.

Patent number: 6759986Abstract: A stacked patch antenna is disclosed which includes a first antenna element and a second antenna element for cooperating with the first antenna element. These antenna elements are preferably a passive parasitic element in combination with a driven element. A flexible substrate is provided having first and second opposing surfaces, each respectively in contact with the first and second antenna elements. The flexible substrate preferably has a desired dielectric property to provide a desired capacitance between the antenna elements. One or both of the antenna elements are formed on the respective opposing surface. The antenna element is preferably formed by printing.Type: GrantFiled: May 15, 2002Date of Patent: July 6, 2004Assignee: Cisco Technologies, Inc.Inventors: Stephen V. Saliga, Fred J.
