[0002] As a solution for modern intelligent management, Bluetooth network access gate control has the characteristics of safety and flexibility and is widely used in community and enterprise scenarios. With the continuous progress of technology and the increasing market demand, Bluetooth network access gate control continues to evolve to provide better experiences and services for users. Due to the limitations of Bluetooth network technology, the effective range is usually between 10 and 100 meters. When the distance at which the mobile control access gate switch device emits a signal is less than the distance from the mobile control access gate switch device to the access gate machine, it indicates that the distance is too far, causing the signal to attenuate as the propagation distance increases, resulting in the access gate machine possibly not accurately receiving the control signal, thereby reducing the control efficiency.
