Dynamic configuration of wireless circuitry to mitigate interference among components in a computing device

摘要

Methods and apparatus to mitigate coexistence interference among multiple wireless subsystems and wired connection ports of a computing device are described. A processor obtains configurations for at least two wireless subsystems and for a connection state of at least one wired connection port. When the first and second wireless subsystem configurations or the connection state of the at least one wired connection port indicate potential or actual coexistence interference, the processor is configured to adjust wireless circuitry of the first and second wireless subsystems. The first wireless subsystem is configured based on frequency bands used by the first and second wireless subsystems, while the second wireless subsystem is configured based on the connection state. In an embodiment, the first wireless subsystem operates in accordance with a wireless personal area network protocol, and the second wireless subsystem operates in accordance with a wireless local area network protocol.
