Wherein, described current power value can refer in radio communication, the performance number of the carrier frequency of certain channel.Such as in mobile communication, the performance number of the 1-124 channel of GSM (GlobalSystemForMobileCommunications, digital mobile communication system), it is actual is exactly the transmission power level of mobile phone in this communication channel.
Optionally, in the embodiment of the present invention, after the described calibration power information obtained in described standard WIFI wattmeter and the described current power information in described current WIFI wattmeter, described current power information can be mated with described calibration power information, thus determine in described M WIFI channel, to mate unsuccessful described N number of WIFI channel.
Concrete, the current power information of described M WIFI channel in the current WIFI wattmeter comprised in corresponding for the calibration power information of described M WIFI channel in described standard WIFI wattmeter and described electronic equipment is mated respectively, determine the unsuccessful N number of WIFI channel of coupling, can comprise: getting i is integer from 1 to M, perform following steps respectively: in described current WIFI wattmeter, determine i-th current power value that i-th WIFI channel is corresponding, and in described standard WIFI wattmeter, determine i-th calibration power value that described i-th WIFI channel is corresponding, wherein, M the WIFI channel of current WIFI and the corresponding relation of current power value is recorded in described current WIFI wattmeter, whether the match is successful to judge described i-th current power value and described i-th calibration power value, determines the unsuccessful described N number of WIFI channel of coupling altogether, wherein, if described i-th current power value mates unsuccessful with described i-th calibration power value, then determine that described i-th WIFI channel belongs to described N number of WIFI channel.
Namely by being mated respectively by described M the WIFI channel comprised in described current WIFI wattmeter and described standard WIFI wattmeter, coupling herein can refer to determines that whether the performance number that in described current WIFI wattmeter and described standard WIFI wattmeter, respective channel is corresponding is consistent.
Such as, the current power value of WIFI channel 1 correspondence in M WIFI channel described in described current WIFI wattmeter is 30dBm, the calibration power value of WIFI channel 1 correspondence in M WIFI channel described in described standard WIFI wattmeter is 34dBm, WIFI channel 1 then in known described current WIFI wattmeter mates unsuccessful with the performance number of the WIFI channel 1 in described standard WIFI wattmeter, thus can determine that the WIFI channel 1 in described current WIFI wattmeter belongs to the described N number of WIFI channel needing to carry out performance number adjustment.
Step 13: according to the corresponding relation between WIFI channel and power bias value, determines the N number of power bias value corresponding with described N number of WIFI channel.
