4.Various characteristics of the phone are measured, then compensation values are created so that the phones behave identically, even though they are not inherently identical.
5.Some compensation values are calculated, some are measured once per design, and some are measured for each and every phone.
6.Individual phones also change their own RF characteristics.
7.RF calibration also compensates for these changes.
The are some details for RF calibration:
1.It is important to carriers that all phones in the field and those still on the store shelves behave more or less identically, at least in terms of radio frequency (RF) characteristics.
2.It is also necessary that they behave the same and within the specifications for the mobile system to function properly.
3.However, due to differences in design and even part-to-part variations of components of the same design, phones would not behave identically without calibration.
