Specifically, relatively previous embodiment, embodiment adds the judges to power adjustment effect, work as power adjustment
When the communication quality brought changes not up to expected, retract to power, so as to avoid work(that is invalid, even having negative interaction
Rate adjusts.
After the transmission power adjusts, keep current transmission power constant in the second preset time period.Second is default
Period is less than the first prefixed time interval, for example, the first prefixed time interval is set as 1 hour, the second preset time period is 5
Minute, a period of time is maintained by the power after adjusting, so as to judge the effect for the communication quality that power adjustment is brought.When
Variation of the two communication mass values compared to the first communication quality value is more than preset ratio and is when reducing, then by the power after adjustment
The value returning back to before adjustment.Preset ratio, it is proposed that be set as 5%, generally, change within 5%, it is believed that it is acceptable, when
Second communication quality value is deteriorated, and more than 5%, then needs to retract performance number.When the variation is no more than preset ratio,
Then maintain the power after adjustment constant；When it is described variation more than preset ratio and for promoted when, then maintain adjustment after power not
Become.
It should be noted that above-described embodiment can be freely combined as needed.The above is only the preferred of the present invention
Embodiment, it is noted that for those skilled in the art, in the premise for not departing from the principle of the invention
Under, several improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
