Further, the value range of the preset time period is 10-60 min, and in this embodiment, 15min is preferred.
The following description will be given taking a specific example:
when a household wireless router detects that no user is connected at night 12:00, the gateway transmission power is reduced to 50% of the maximum transmission power, when two users are connected at 12:30, the transmission power is firstly increased to 80%, the RSSI value of each user is recorded (every other minute) until the user exits the connection (no connection is adjusted back to 50%), or the user is still used after 1:00 is reached, the ratio of the RSSI values of all the users in the half hour of 12: 30-1: 00 in four intervals of [ infinity, -80], (-80, -70], (-70, -60], (-60,0] is calculated, the RSSI values of all the users in the half hour are respectively 10%, 20% and 50% (the higher RSSI range is within the first preset ratio range [50,100 ]), the gateway transmission power is adjusted to the sixth percentage, namely 30%, corresponding to the higher RSSI range, and then the user connection in the half hour is continuously detected And the signal quality is adjusted until no connection is finally adjusted back to 50% (in the half hour of 30% power, there may be a situation that the signal quality is degraded, and the user will disconnect to reconnect, and here, it can be set that the power is adjusted back to 80% again when the user is detected to reconnect for a plurality of times within a short time, such as 3 min). More humanized, in this embodiment, it can be designed that when no device is connected within one hour, the gateway transmission power is adjusted to a low state of 20%, so as to greatly save power.
Taking a common two office workers who live in one house as an example (referring to the situation that two people share one router and no other user maliciously rubs on the net), sleep at 12 pm (default rest is no connection), get up at 7 am, get out at 8 am, go back at 7 pm, have power 50% in 1 hour between 12 and 7 pm, 20% in the last 6 hours, 80% in 0.5 hour before 7-8 pm, 30% in the last 0.5 hour (assuming that signals are all in a higher RSSI range), 50% in 1 hour between 8 pm and 7 pm, 20% in the last 10 hours, and 7-12 pm, as the specific power is 30-80%, it can be seen that the transmission power of one working day is on average below 50%, and compared with the existing situation that the whole day runs at the maximum power, the electric quantity can be saved by at least half.
The self-adaptive adjusting method for the gateway transmitting power provided by the embodiment of the invention automatically adjusts the gateway transmitting power of the router according to the connection condition of the current network equipment and the signal quality, reduces the transmitting power by half or even lower when no equipment is connected, reduces the transmitting power by half when the signal quality of equipment connection is better, and sufficiently reduces the transmitting power as far as possible on the premise of ensuring the signal quality of a user, thereby saving a large amount of electric quantity.
