Abstract: This disclosure provides a monitoring device, a wireless communication device, and a control method. The monitoring device includes a control system assembly, a digital-analog mixing assembly, a frequency band selection assembly, and an antenna. The control system assembly is respectively connected with the digital-analog mixing assembly and the frequency band selection assembly; one end of the frequency band selection assembly is connected with the digital-analog mixing assembly through a channel of designated frequency band, and the other end of the frequency band selection assembly is connected with the antenna. The monitoring device can switch from a currently used frequency band to other frequency bands for signal transmission or use other frequency bands for simultaneous signal transmission, according to a signal transmission status of the currently used frequency band. Thus, the anti-interference ability of the monitoring device can be improved to reduce the error rate of signal transmission.
