Embodiment Construction
[0032] The communication device provided by the embodiments of the present application, its signal sending and receiving method, and the switching circuit are described in detail below in conjunction with the accompanying drawings.
[0033] In order to improve the performance of the AP, two types of antennas can be integrated in the AP. The radio frequency signal processing circuit connected to the first type antenna is used to process service signals, and the radio frequency signal processing circuit connected to the second type antenna is used to realize auxiliary functions. The auxiliary functions may include dynamic frequency selection, spectrum scanning, signal strength location and radio frequency fingerprinting, etc.
[0034] Multiple first-type antennas and multiple second-type antennas may be integrated into the AP. The working frequency band of the RF signal processing circuit connected to each type of antenna can be 2.4 gigahertz (GHz) or 5GHz, and the working freq...

The invention provides communication equipment, a signal transceiving method thereof and a switching circuit, and belongs to the technical field of communication. The communication device comprises a first radio frequency signal processing circuit and a second radio frequency signal processing circuit. According to the method, in a first downlink time period, the signal transmitting function of the first radio frequency signal processing circuit is started, and the signal receiving function of the second radio frequency signal processing circuit is closed; and in a first uplink time period, the signal receiving function of the first radio frequency signal processing circuit can be started, and the signal transmitting function of the second radio frequency signal processing circuit can be closed. Therefore, the radio-frequency signal processing circuit in the communication equipment does not receive signals transmitted by other radio-frequency signal processing circuits, so that the service life of the radio-frequency signal processing circuit can be prevented from being influenced due to the fact that the radio-frequency signal processing circuit works in a saturation region for a long time, and the working performance and the service life of the radio-frequency signal processing circuit in the communication equipment are ensured.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a communication device, a signal sending and receiving method thereof, and a switch circuit. Background technique [0002] In a wireless local area network (wireless local area network, WLAN) service, in order to improve the performance of an access point (AP), a greater number of radio frequency signal processing circuits can be integrated in the AP, and the radio frequency signal processing circuit is used for processing The signal sent and received by the antenna to which it is connected. [0003] When the radio frequency signal processing circuit connected to a certain antenna is in transmit (transmit, TX) mode, if the strength of the signal transmitted by the radio frequency signal processing circuit is high, and the isolation between the antenna and other antennas is poor, then The strength of the signal received by the radio frequency signal processing...
