Step 101, under maximum transmission power, measure the radiation dispersion produced when launching antenna as mobile device of each antenna in multiple antenna respectively；
In implementing, multiple antennas refer to two or more antenna, and in multiple antennas, each antenna can switch the transmitting antenna as mobile device.
Step 102, when the plurality of antenna exists the antenna that radiation dispersion exceeds standard, the antenna exceeded standard according to described radiation dispersion obtains the maximum transmission power calibration value of the antenna that described radiation dispersion exceeds standard as mathematic interpolation between measured value and the standard value of radiation dispersion when launching antenna；
Step 103, the maximum transmission power calibration value of the antenna exceeded standard by described radiation dispersion are stored in described mobile device.
In the present embodiment, the antenna that radiation dispersion exceeds standard can be one or more, only adjust the maximum transmission power of the antenna that radiation dispersion exceeds standard, if multiple antenna does not exist the antenna that radiation dispersion exceeds standard, then need not adjust the maximum transmission power of any one antenna.
In the present embodiment, before mobile device is dispatched from the factory, it is calculated antenna maximum transmission power calibration value that radiation dispersion in mobile device exceeds standard and maximum transmission power calibration value is stored in a mobile device, during using after mobile device is dispatched from the factory, the maximum transmission power calibration value that mobile device can directly invoke each antenna corresponding communicates, and thereby may be ensured that the radiation dispersion of each antenna does not exceeds standard.

| Difference | Power adjustment |
| 3dBm | 1dBm |
| 6dBm | 2dBm |
