Embodiment approach

[0037] refer to figure 1 , figure 1 It is a flowchart of an embodiment of the power adjustment method of the present application. This embodiment is described from the perspective of a power regulating device, where the power regulating device may be a gateway or a router. This implementation mode includes the following steps:

[0038] S101: Receive a signal sent by a terminal device.

[0039] After the power adjustment device is started, it works with the default preset transmit power. When the terminal device needs to access the power adjustment device, it sends a signal to the power adjustment device to request access to the power adjustment device; or, after the terminal has access to the power adjustment device, the terminal can perform signal interaction with the power adjustment device. The power adjustment device receives the signal sent by the terminal equipment.

[0040] Specifically, in this embodiment of the present invention, the power adjustment apparatus re...

Abstract

The invention discloses a power adjusting device and method. The device comprises a receiving module, an obtaining module, an adjusting module and a sending module. The receiving module is used for receiving signals of a terminal device. The obtaining module is used for obtaining a signal quality index according to the signals received by the receiving module, wherein the signal quality index is used for identifying the signal quality of signals which are sent by the power adjusting device and received by the terminal device. The adjusting module is used for adjusting the emission power according to the signal quality index after the obtaining module obtains the signal quality index. The sending module is used for sending signals according to the emission power adjusted by the adjusting module. According to the above scheme, the power adjusting device is capable of dynamically adjusting the emission power according to the signal quality index of the signals received by the terminal device, the receiving performance of the terminal device is ensured, and the reliability of communication is enhanced.

Description

technical field [0001] The present application relates to the field of communication networks, in particular to a power adjustment device and method. Background technique [0002] With the development of wireless network communication technologies, wireless fidelity (Wireless Fidelity, WiFi) technology is more and more widely used, and more and more terminal devices are connected to a core network through a WiFi access point (Access Point, AP). Since the quality of the signal received by the terminal device from the WiFi access point is affected by factors such as the distance from the terminal device to the WiFi access point and environmental interference, in order to ensure that the terminal device can always receive the signal from the WiFi access point well and reduce the Energy consumption, the transmit power of the WiFi access point needs to be adjusted, for example, when the terminal device is relatively close to the WiFi access point, reduce the transmit power of the...
