Patent number: 10178683Abstract: Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.Type: GrantFiled: January 19, 2017Date of Patent: January 8, 2019Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Prasanna Desai, Kelly Coffey, Robert Hulvey, Mark Gonikberg
