Patent number: 11729707Abstract: In some embodiments, an apparatus includes a spectral scanning controller configured to interrupt service at a wireless access point (WAP) such that the WAP performs spectral scanning during service interruption. The spectral scanning controller is configured to interrupt service at the WAP at a first scanning frequency when the spectral scanning controller is in a first configuration. The spectral scanning controller is configured to interrupt service at the WAP at a second scanning frequency different from the first scanning frequency when the spectral scanning controller is in a second configuration. The spectral scanning controller is configured to move from the first configuration to the second configuration in response to a change in at least one of a service demand, a service quality, a spectral scanning demand or a spectral scanning quality.Type: GrantFiled: January 29, 2016Date of Patent: August 15, 2023Assignee: Juniper Networks, Inc.Inventors: Liang-Jong Huang, Lap Kong Law

Patent number: 11522800Abstract: The present disclosure is directed generally to systems and methods for dynamically selecting a retransmission rate for communication between two devices. The retransmission rate may be selected after a transmission has failed between the devices. In some embodiments, the retransmission rate may be selected based on relative velocity of the devices. In some embodiments, the retransmission rate may be selected based on transmission channel characteristics. The retransmission rate may be selected such that the retransmission will be less than an allowable transmission rate based on a distance between the two devices.Type: GrantFiled: October 19, 2020Date of Patent: December 6, 2022Assignee: BELDEN, INC.Inventor: Lap Kong Law

Patent number: 10980070Abstract: Wireless access points may automatically discover each other and establish connections based on accumulated credit values incremented via mutual exchanges of identifiers. A first access point may select a candidate access point for a potential connection, and may maintain a credit value for the selected candidate access point. The first access point may broadcast beacon messages, including an identification of the candidate access point and the credit value. Responsive to detecting a broadcast from the candidate access point including an identifier of the first access point, the first access point may increment the credit value. As each access point continues broadcasting beacon messages, it may increment its credit value for the other access point accordingly.Type: GrantFiled: August 26, 2019Date of Patent: April 13, 2021Assignee: Hirschmann Automation and Control GmbHInventors: Lap Kong Law, Bernhard Wiegel, Constantin Baciu
