Problems solved by technology

Although these methods can reduce the energy consumption of the radio frequency module to a certain extent, these methods all affect the user experience
For example, increasing the Beacon Interval may cause users to slow down the process of discovering the network; and simply reducing the RF transmission power and stopping part of the PA work will result in a smaller RF coverage, which may cause users to be unable to connect to the wireless network in some locations. into the network, thus degrading the user experience

Embodiment 1

[0019] figure 1 It is a schematic structural diagram of a wireless access point according to Embodiment 1 of the present invention, the wireless access point includes: a first monitoring module 10, configured to continuously monitor the packet loss rate of a workstation associated to the wireless access point; a judging module 20 , for judging whether the packet loss rate currently monitored by the first monitoring module 10 is less than the first threshold, if so, triggering the adjustment module 30 to reduce the radio frequency transmission power of the wireless access point step by step; the adjustment module 30 is used for The radio frequency transmission power of the wireless access point is adjusted according to the trigger of the judging module 20 .

[0020] In related technologies, methods such as increasing Beacon Interval, simply reducing radio frequency transmission power, or stopping part of PA work are used to reduce the energy consumption of wireless APs. These m...

Embodiment 2

[0040] Figure 5 It is a schematic diagram of an application scenario according to Embodiment 2 of the present invention. In this embodiment, there is only one workstation (STA) associated with a wireless access point. When the STA moves from position 1 to position 2 and then to position 3, when When the STA approaches the wireless AP, the wireless AP reduces the radio frequency transmission power according to the received signal strength and the statistical packet loss rate. When the STA is far away from the wireless AP, the wireless AP detects that the received signal strength is deteriorating, and the statistical packet loss rate increases and exceeds the threshold, then increase the RF transmission power until the packet loss rate returns to normal, or enter the full power state.

[0041] Figure 6 It is a flowchart of a method for adjusting radio frequency transmission power of a wireless AP according to Embodiment 2 of the present invention, which mainly includes the fo...

Embodiment 3

[0052] Figure 7 It is a schematic diagram of an application scenario according to Embodiment 2 of the present invention. In this embodiment, STAs associated with a wireless access point include: STA1, STA2, and STA3.

[0053] Figure 8 It is a flowchart of a method for adjusting radio frequency transmission power of a wireless AP according to Embodiment 3 of the present invention, which mainly includes the following steps:

[0054] Step S801, the wireless AP starts to enter the full power operation state, that is, the current radio frequency transmission power of the wireless AP is its maximum radio frequency transmission power;

[0055] Step S802, STA1, STA2, and STA3 are associated to the wireless AP, and the wireless AP counts the packet loss rate with each STA, and obtains the current received signal strength of each STA;

[0056] Step S803, the wireless AP judges whether the packet loss rate with each STA is less than the first threshold, if yes, execute step S804, oth...

Abstract

The invention discloses a wireless access point and a radio-frequency emission power regulation method thereof. In the method, the wireless access point is used for continuously monitoring packet loss rate of a workstation which is connected with the wireless access point; and when the packet loss rate is less than a first threshold value, the radio-frequency emission power is reduced by the wireless access point step by step. By using the invention, on the premise that data pass between the wireless access point and the workstation is not affected, radio-frequency emission power can be reduced to the largest extent and the whole energy consumption of the wireless access point is reduced effectively.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a wireless access point and a method for adjusting radio frequency transmission power thereof. Background technique [0002] As a network access method, a wireless local area network (WLAN for short) has the advantages of high access speed and simple wiring, and is more and more widely used in home networks. Studies have shown that the energy consumption of WLAN is mainly concentrated in the base band (BB) and radio frequency (Radio) modules of the wireless access point (Access Point, referred to as AP), and the energy consumption of the Radio module accounts for 50% in the receiving mode. The BB module accounts for about 20%; while in the sending mode, the Radio module consumes about 91% of the energy, and the BB module accounts for about 3%. Therefore, no matter in the sending mode or the receiving mode, the energy consumption of the radio frequency module accounts for a lar...
