Abstract: A radio frequency front end module (FEM) coupled to a radio frequency transceiver circuit and includes a first port coupled to a sending branch and a receiving branch through a switching system, and a second port coupled to the sending branch and the receiving branch through the switching system. The first port supports signal transmission of a first frequency band, and the second port supports signal transmission of a second frequency band. The receiving branch supports receiving processing of signals of the first frequency band and the second frequency band. The sending branch supports sending processing of signals of the first frequency band and the second frequency band. The switching module is configured to selectively transmit a signal either processed by the sending branch to the first port or the second port, or received by the first port or a signal received by the second port to the receiving branch.

Abstract: A sensing method and apparatus, to combine a sub-7 GHz frequency band and an mmWave frequency band for Wi-Fi sensing, and improve performance of sensing a Wi-Fi signal. The method includes: receiving a plurality of first communication data frames in the first frequency band and a plurality of second communication data frames in the second frequency band, where a frequency of the first frequency band is higher than a frequency of the second frequency band; and obtaining a plurality of pairs of communication data frames, where each of the plurality of pairs of communication data frames includes a first communication data frame in the first plurality of communication data frames and a second communication data frame in the second plurality of communication data frames, and a time difference between a first timestamp of the first communication data frame and a second timestamp of the second communication data frame falls within a preset threshold range.
