Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0028] The invention provides a method for adjusting power, which is applied to a wireless controller and used for managing multiple radios accessing APs.

[0029] see figure 1 , figure 1 It is a schematic flowchart of a method for adjusting channel and power in an embodiment of the present invention. The specific steps are:

[0030] Step 101, during the AC power adjustment process for any Radio, when the difference between the signal strength of the management neighbor Radio with the weakest signal strength and the preset adjustment threshold is greater than the preset downward adjustment interval, and the current power is not greater than the preset minimum When transmitting the power threshold, a high-density group is created, and...

Abstract

The invention discloses a method for regulating power. The method comprises the following steps of: adding a new judgment branch during a former power regulation process; if the power of a current-regulated Radio is a minimum value and the power further needs being regulated to be less, regarding that a high-density deployment condition of AP (Access Points) exists in the area of the Radio; and carrying out a channel allocation and a power regulation by adding a high-density group. Based on the same inventive concept, the invention further provides a device capable of leading the Radio of a plurality of the APs which provide services within the same area to be a maximum sending power.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for adjusting power. Background technique [0002] The propagation of wireless signals is affected by the surrounding environment, and problems such as multipath will cause complex attenuation phenomena of wireless signals in different directions. Therefore, the implementation of WLAN networks often requires careful network planning. Even after the wireless network is successfully deployed, parameter adjustment in the application stage is still necessary, because the wireless environment is constantly changing, and the interference caused by moving obstacles and working microwave ovens may affect the wireless signal. Propagation is affected, so radio frequency resources such as channels and transmit power must be dynamically adjusted to adapt to changes in the user environment. Such an adjustment process is complicated and requires extensive te...
