Abstract: Various embodiments include techniques for reducing high-frequency interference to a wireless communications channel emanating from a wired communications channel. The techniques are directed towards an application that determines a mode of a particular wired communications channel. The mode of the wired communications channel is indicative of the frequency ranges at which the interference is generated. The application further determines a frequency and/or bandwidth of the wireless communications channel. The application selects a slew rate that reduces the high frequency interference from the wired communications channel at the frequency and/or bandwidth of the wireless communications channel. The application thereby optimizes the reduction of the high-frequency interference from the particular wired communications channel to the particular wireless communications channel.

Abstract: In various examples, radio frequency conducted power of a device—such as a human interface device (HID)—may be adjusted to account for various operating conditions. For example, when a user holds the device in their hand, the radiated power level of the device may be reduced to a level that reduces transmission performance of the device. To account for this, one or more detection mechanisms may be used to determine whether the device is held in hand and, when determined to be held in hand, the radio frequency conducted power of the device may be increased—while complying with regulatory requirements governing wireless transmissions—to increase the performance of the device. When not held in hand, the radio frequency conducted power may be less, thereby resulting in consistent performance of the device under varying operating conditions.

Abstract: Techniques for providing multi-antenna devices with increased antenna-to-antenna isolation as well as methods of operating and manufacturing the same are disclosed. A multi-antenna device may include a support structure, one or more radio devices coupled to a first antenna that is coupled to the support structure at a first location, a second antenna coupled to the support structure at a second location and communicatively coupled to the one or more radio devices, and a conductive structure coupled to the support structure so that it shifts an electric field null of the first antenna from an original location toward the second location during communications using the first antenna, thereby increasing isolation between the first antenna and the second antenna. The conductive structure may have a length of approximately one half of the wavelength (e.g., of 2.4 gigahertz or 5 gigahertz) of a frequency band used for the communications.
