Description of drawings

Embodiments of the present invention are more fully described with reference to the accompanying drawings. However, the accompanying drawings are for illustration and illustration only, and do not limit the scope of the present invention.

Fig. 1 is the flowchart of the automatic adjustment method of a kind of router transmission power of the present invention;

FIG. 2 is a schematic structural diagram of a device for automatically adjusting transmit power of a router according to the present invention.

Detailed ways

A method for automatically adjusting transmit power of a router according to the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, a method for automatically adjusting the transmit power of a router includes steps:

Obtain the device connection rate and device signal strength of the device connected to the router; wherein, the device connection rate is the actual bandwidth used by the data traffic of all devices connected to the router, and the factors that affect the device signal strength include partition walls, distance , router type and aging degree, etc.;

periodically sampling the air interface transmission power of the router; wherein the air interface transmission power is the real-time transmission power of the router obtained through calculation;

According to the result of the transmission power of the air interface obtained in N consecutive sampling periods, it is judged whether it is necessary to adjust the level of the transmission power of the router; wherein, N is a positive integer greater than 0.

Specifically, in this embodiment, the transmission power of the air interface is firstly sampled periodically. The formula for calculating the transmit power of the air interface is:

Power＝Po+Sigma{Fi*Ri*Si}

Among them, Power is the transmission power of the air interface, Po is the minimum transmission power, and Fi is the influencing factor. The influencing factors include hardware memory, the channel of the connected device, and external environmental interference. Ri is the device connection rate, that is, the actual bandwidth used when the device connected to the router obtains data traffic. Si is the signal strength of the device, that is, the actual signal strength of the signal obtained by the device connected to the router. Factors affecting the signal strength of the device include partition walls, distance, device type, and aging degree.

In this embodiment, the transmission power of the air interface is obtained through periodic data sampling, and the user can set the minimum transmission power, adopt the period, adjust the preset and the effective times through the transmission power of the air interface. In practical applications, the usage scenarios of routers include the following situations:

1) If no user equipment is connected, the transmit power of the router will use the default value;

2) When the traffic is very low, the transmit power of the router will reach the minimum value;

3) When the memory is full, the transmit power of the router will reach the maximum value;

4) In the case of channel interference, the transmit power of the router will be dynamically adjusted;

5) Different data traffic, the transmit power of the router will be adjusted dynamically;

6) In the same location, different devices will have different signal strengths.

In this embodiment, it can be seen that the adjustment thresholds of router transmission power are divided into several situations, preferably five categories: lowest, low, medium, high and highest, and the number of valid configurations is N times, preferably N is 3. Specifically, in three consecutive sampling periods, if the air interface transmit power calculated each time exceeds a certain threshold range and is different from the original adjusted transmit power range of the router, the transmit power level of the router will be automatically adjusted .

Specifically, the transmit power of the router is divided into several types, and when the transmit power of the router is any one of them, the transmit power of the air interface is periodically obtained. If it is found that the transmission power of the air interface exceeds or is lower than the transmission power of the router at this time in N consecutive periods, the transmission power is increased or decreased accordingly.

The automatic adjustment method of router transmission power can perform intelligent and dynamic wireless transmission power calculation and real-time adjustment, which greatly improves the user experience effect of wireless power control. The method is simple and convenient, without distinguishing the state of the user, and can conveniently adjust the transmission power of the air interface, so that the operation of the router is more stable and safe, while reducing the packet loss rate, saving energy and environmental protection, improving the performance of the router and prolonging the service life.
