摘要： A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.

摘要： Devices and systems useful in concurrently receiving and transmitting Wi-Fi signals and Bluetooth signals in the same frequency band are provided. By way of example, an electronic device includes a transceiver configured to transmit data and to receive data over channels of a first wireless network and a second wireless network concurrently. The transceiver includes a plurality of filters configured to allow the transceiver to transmit the data and to receive the data in the same frequency band by reducing interference between signals of the first wireless network and the second wireless network.

摘要： The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.

摘要： Systems, methods, and devices are provided to efficiently share an antenna between multiple communication systems and allow for the communication systems to be simultaneously connected to the antenna with less attenuation and/or no fluctuation in signal strength. Communication circuitry may include an antenna that transmits and receives electromagnetic radiation. The communication circuitry may also include an antenna port that provides primary access to the antenna with a first attenuation via an antenna port input. Additionally, the communication circuitry may include a coupler attached to the antenna port. The coupler may provide secondary access to the antenna with a second attenuation.

摘要翻译：用于减少对传导RF链路的干扰的技术涉及确定电子设备中的主动无线信道。例如，设备可以确定是否存在活动的蜂窝，WiFi和/或蓝牙信道。如果是这样，可以从可用于生成用于传导RF链路的RF信号的可能信道的列表中移除任何活动信道。如果任何空闲信道保持可用，则可以选择一个或多个用于所传送的RF链路。那些具有比任何活动通道偏移较大的空闲信道可能在选择中给予较大的权重，因为它们应该不太可能受到干扰。如果不是，可以选择最不拥挤的活动频道中的一个用于传导的RF链路。
