Abstract

The invention discloses a transmission power control method and device of wireless communication equipment. The control method includes steps: S100, causing the wireless communication device to transmit a signal; S200, detecting the power value of the current transmitted signal, and adjusting the transmission power according to the power value of the current transmitted signal; S300, detecting the adjusted transmission power The quality of the transmitted signal, and fine-tune the transmission power according to the quality of the transmitted signal. The control method of the present invention adopts a closed-loop control scheme to improve the accuracy of power control, especially adopts a double closed-loop control scheme combining power feedback and signal quality feedback for control, which can take into account both transmission power and transmission signal quality, and achieve joint regulation. It has the advantages of low cost, high precision, and the ability to adapt to impedance changes.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for controlling transmission power of wireless communication equipment. Background technique [0002] With the continuous increase of various consumer electronic devices and smart home appliances, wireless communication technologies such as WIFI and Bluetooth (BT) are more and more favored by device manufacturers because of their advantages in data transmission and networking. [0003] On the one hand, with the access of more and more devices, when these devices are in different working modes and working scenarios, their transmission power requirements are also different. For example, in order to better optimize the power consumption and experience of communication devices, it is necessary to set different power level requirements for devices at different distances and for different users. In this case, it is necessary to consider wheth...
