Methods and apparatus for dynamically compensating for the effects of interference between multiple wireless communications apparatus. In one embodiment, the method comprises providing a first wireless communication apparatus operating in a first band and a second wireless communication apparatus operating in the same first band (or proximate to the first band and with a comparatively high transmitter power), where the second wireless communication apparatus operates according to a different communication protocol than the first wireless communication apparatus and further change in physical configuration with respect to one another. Based on the physical configuration, interference is compensated for between the first wireless communication apparatus and the second wireless communication apparatus 'on the fly' by selecting and operating according to one of a plurality of operational protocols.

Methods and apparatus for dynamic wireless device coexistence

A system and method for improved wireless communications at a host device (e.g., a portable computing device, a mobile communications device) having multiple wireless communication abilities (e.g., Bluetooth&#xae; and Wi-Fi&#xae;). When a component (e.g., a monitor, an Ethernet dongle) having Bluetooth capability is coupled to the host device (e.g., wired or wirelessly), the host device copies its Bluetooth link keys to the component, deactivates its own Bluetooth module and activates (or initiates activation of) the component's. The component's Bluetooth module is operated using a software stack executing on the host device. Thereafter, the component handles Bluetooth operations and the host device communicates with Bluetooth devices via the component. Greater radio isolation is thus provided between antennae used by Bluetooth and Wi-Fi.

System and method for using an external component to conduct wireless communications

Electronic devices such as portable computers may contain circuits that generate radio-frequency noise. The radio-frequency noise may interfere with the operation of sensitive circuitry such as wireless communications circuitry. The circuits that generate the radio-frequency noise may include differential signal drivers that drive signals onto communications lines such as lines in a bus or output interface. A control circuit may power the drivers at an adjustable driver voltage bias level. The amount of noise that is generated by the drivers may vary as a function of the voltage bias level and may produce different amounts of noise at different wireless frequencies. Computer lid position and other factors may also influence the amount of interference that is generated. The control circuit may determine the current operating state of the device and may make voltage bias level adjustments that minimize interference between the drivers and the wireless circuitry.

Electronic device with dynamic drive strength adjustment to mitigate impact of system noise on wireless performance

The disclosed embodiments provide a system that facilitates communication with a storage device. During operation, the system provides a physically operated mechanism for enabling detection of the storage device in proximity to a computer system using a discovery protocol. If detection of the storage device using the discovery protocol is enabled, the system uses the physically operated mechanism to establish a wireless peer-to-peer connection between the storage device and the computer system. The system then uses the wireless peer-to-peer connection to transfer a file between the storage device and the computer system.
