HARDWARE (THE HARD)

1. RF (Radio Frequency)
RF system is the part that serves to transmit information, this section will act as a wireless system in the cellular system. RF System there are two sets of RF terintergrasi in the system, namely:

* SA: Swith Antenna
* LNA: Low Nois Amplifier
* RF: Radio Frequency
* VCO: Voltage Control Oscilator
* PA: Power Amplifier
* OSC: Oscilator
* RX: Receiving data dibase information station
* TX: The sender of data information to base station

2. BB (BaseBand)
This section is part of the input or output of the entire phone system.
3. UI (User Interface)
UI (User Interface) is the section that will connect information from the phone system to mobile phone users, or vice versa, eg you will send SMS, then you should be pressing the phone keypad so you can receive commands that we type. Or there is an incoming call to the mobile phone the phone will ring so that users can immediately receive a phone call. Components that are always associated with one mobile phone users such as keypad, LCD, buzzer, Vibrator, LED, etc..

SOFTWARE (SOFTWARE)

1. MCU
MCU (Micro Controller Unit) is the operating system program data, which contains routine-routine, procedures, version, logic, blutooth code, but also to control and coordinate the activities of a oprasai system.
2. PPM
PPM (Post Memory Programming), namely the data from the program containing the software language, ringtone, picture, fantasy, a list of all network, country code, etc.. Language is a software program created as a translator between the written language with the day-to-harimenjadi bahassa engine berbentukbilangan binary. Bundles / language options available on the phone, called language pack. Software language on nokia mobile phone are on the PPM data. Language packs that are on the phone will vary depending on the area for phone sales, eg if the phone will be sold to Europe by the manufacturer on the akan language packnya not there is a choice of languages of Indonesia. Unlike the mobile phone that will be sold diasia, in the language selection will be English.
3. EEPROM
EEPROM (Electrically Erasable Programmable Read Only Memory) has a duty to save the information that has been programmed by the manufacturer the phone itself. stored in the EEPROM are:

* No IMEI (International Mobile Equipment Identifier)
* Security code
* ESN (Electronic Serial Number)
* MIN (Mobile Identification Code)
* SID (system Identification Code)
