Method and device for controlling wireless transmitting power

Abstract

Embodiments of the invention provide a method and a device for controlling wireless transmitting power. The method comprises the following steps that a wireless device detects wireless signal strength of each wireless terminal which communicates with the wireless device; and the wireless device judges the relationship between the wireless signal strength of each wireless terminal and a signal strength threshold and adjusts the wireless transmitting power of data which is sent to each wireless terminal by the wireless device according to a judging result. According to the method and the device for controlling the wireless transmitting power, which are provided by the embodiments of the invention, the disturbance of the environment to a wireless terminal signal can be more precisely recognized, so that a purpose of further reducing the transmitting power consumption is realized.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for controlling wireless transmission power. Background technique [0002] Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), typically using the 2.4GUHF or 5G SHF ISM radio frequency bands. Connections to WLANs are usually password-protected; however, they can also be open, allowing any device within range of the WLAN to connect. Wi-Fi is a brand of wireless network communication technology, held by the Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on the IEEE 802.11 standard. The local area network using the IEEE 802.11 series protocol is usually called wireless fidelity, and even Wi-Fi is equated with the wireless Internet (Wi-Fi is an important part of WLAN). [0003] Wi-Fi connects to the network through radio waves. Th...

Problems solved by technology

For example: when the client connects to the wireless access point (AP, Access Point) and goes online, the AP can be a wireless router. If the AP and the client can exchange data at a high rate, it means that the wireless channel between them Better, so gradually reduce the transmit power on the AP on the premise of ensuring the high-speed transmission of the two, but if the wireless environment deteriorates or the transmit power is too low and packet loss or slowdown occurs, the AP will increase its transmit power

[0007] However, the current existing technology controls the power of wireless devices based on the data transmission rate, and there are the following technical problems. For example, there are many factors that determine the user data transmission rate, and environmental interference is only one of the factors, which cannot be obtained simply based on the rate change. Draw the conclusion that the wireless environment is getting better or worse

At the same time, the existing solution is to adjust the wireless transmission power as a whole, which does not achieve precise power control, and there is still some waste of energy
