Nevertheless, cells which can be sufficiently distant from one another can use the identical frequencies. When a cell phone leaves one cell and enters one other, the phone name is transferred from one base station to a different, and the set of transmission frequencies to the following, utilizing a computerized switching system.

The method of transmitting radio frequencies from one cellular phone to a different may be made doable by the totally different elements and features of the cell phone.

o Oscillator – additionally referred to as clock frequency. It creates low frequencies, used to run digital parts and helps to place off energy on failure.

o Frequency divider – utilized in cell phones to divide clock frequency and obtain correct frequency to run digital parts. This half is built-in radio ICs, the equal of Hagar IC or Mojoelner in Nokia cell phones.

o CPU – Central Processing Unit is the mind of the cell phone and controls the foremost elements of unit. It’s vital within the boot testing course of. CPU is vitally related to reminiscence chips and flash chips.

o Flash chips – Flash chips maintain booting data. It has saved directions for the CPU to manage different parts.
