Calibration of power value is penetrated, if measured value is not more than corresponding standard value in the frequency range, then can not have to the emission maximum for adjusting the frequency range
Power raw value, it can think that, in the frequency range, maximum transmission power calibration value is identical as maximum transmission power original value；According to this
Analogize, confirms whether the antenna needs to adjust in the maximum transmission power original value of other working frequency range respectively.Such frequency-division section
Confirmation, can be adjusted with frequency-division section, be unlikely to simultaneously all to reduce the maximum transmission power original value of each frequency range of the antenna, full
While sufficient RSE standard requirements, it ensure that user being capable of normal use mobile device.According to above method, can calculate
To another antenna each working frequency range maximum transmission power calibration value.
| Difference | Power adjustment |
| 3dBm | 1dBm |
| 6dBm | 2dBm |
