Publication number: 20240015592Abstract: Methods and a system described herein form collections of stations based on capabilities and classification of the station and on radio capacity and link budgets of the bands in which the stations operate. Once a collection is formed, a check occurs to determine if there is a rebalancing event, such as a change in the capabilities and classification of a station or a change in the radio capacity and link budgets. If so, then the stations are reassigned to different collections. If no rebalancing event occurs, then the assignment is checked to determine if the loads on the links are well-balanced. If so, a radio link recommendation is sent to the stations.Type: ApplicationFiled: April 20, 2023Publication date: January 11, 2024Inventors: Vishal S. DESAI, Pooya MONAJEMI, Santosh B. KULKARNI

Patent number: 11855914Abstract: Embodiments herein describe a group of APs that uses a shared radar cache to select a new channel after vacating a current channel when performing dynamic frequency selection (DFS). The group of APs can set aside memory to store status information about the DFS channels in the frequency band. For example, when one AP detects a radar event (and has to vacate a DFS channel), the AP updates an entry for that channel in the shared radar cache. The APs can also query the cache to determine a new channel after vacating its current channel. That is, the shared radar cache may store the most recent radar events occurring in a channel. In this manner, the APs can select a new channel that has little or no recent radar events, which reduces the likelihood the AP will have to vacate the new channel.Type: GrantFiled: November 27, 2019Date of Patent: December 26, 2023Assignee: Cisco Technology, Inc.Inventors: Santosh B.
