Abstract: A wireless communication device is described. The wireless communication device includes a processor, a memory in communication with the processor and instructions stored in the memory. The instructions are executable by the processor to detect a signal degradation indication for a radio frequency (RF) signal. The instructions are also executable by the processor to cause a switch to select a combination of a first matching network and a second matching network coupled to an antenna in response to detecting the signal degradation indication.

Abstract: Exemplary systems, apparatus, and methods described herein may improve a scan process for near field communications, such as IEEE 802.15.4. The improvements may include, during the scan process, performing one of increasing a current of a voltage controlled oscillator (VCO)/digitally controlled oscillator (DCO) of a second wireless device, reducing a bandwidth of a phased locked loop, increasing the bandwidth of the phased locked loop, changing a reference frequency of the phased locked loop, or dithering the reference frequency.

Abstract: A wireless communication device is described. The wireless communication device includes a transmit/receive (T/R) switch that is configured with an antenna port coupled to an antenna, a transmitter port coupled to a transmitter and a receiver port coupled to a receiver. The T/R switch selectively connects the transmitter port to the antenna port or the receiver port to the antenna port. The wireless communication device also includes a T/R switch controller that sets the T/R switch to disconnect the transmitter from the antenna when the transmitter is actively transmitting in a high insertion loss mode to reduce power from the transmitter to the antenna.

Abstract: An apparatus for wirelessly transmitting charging power is provided. The apparatus comprises a transmit coil configured to generate a wireless charging field for wirelessly transmitting charging power when driven by a current. The apparatus comprises a control circuit configured to cause the transmit coil to transmit a packet via the wireless charging field, wherein the packet comprises information indicative of the presence of the wireless charging field to cause a chargeable device to electrically disconnect a communication circuit from a receive coil within the chargeable device. The control circuit is further configured to cause the transmit coil to transmit the packet periodically based on a predetermined interval. The predetermined interval has a shorter duration than a duration of a communication interval of the communication circuit. The control circuit is further configured to reduce a magnitude of a strength of the wireless charging field during packet transmission.

Abstract: A method for reducing transmission interference is described. The method includes determining that an FM receiver is turned on. The method also includes determining that the FM receiver is tuned to an FM channel experiencing interference from an induction-based communication transmitter. The method further includes adjusting a transmit frequency of the induction-based communication transmitter by a temporary frequency shift.

Abstract: Systems and methods are disclosed that may detect a likely presence of a narrow band signal in the presence of wide-band interference without powering up a wireless receiver. A wireless device may receive a wireless signal, measure a first energy level in a first frequency band associated with an expected frequency band of the narrow band wireless signal, measure a second energy level in a second frequency band that is offset from and non-overlapping with the first frequency band, and determine whether a difference between the first energy level and the second energy level exceeds a threshold. A wireless receiver of the wireless device may be powered up based at least in part on the difference between the first energy level and the second energy level exceeding the threshold.
