Components Handphone

2009-12-01T09:01:00.000+07:00

In a mobile device that is used a lot of components such as transistors, IC (Intergrated Circuit), Dioda, and so forth. To be able to understand the series of bekerjanya on the mobile device should be the nature of the components that are important. Components of the mobile device can be classified into two parts, namely internal and external components. The picture above is an example of form slah components are mounted on a mobile phone.

Mobile wireless communication equipment

2009-12-01T09:00:00.002+07:00

Mobile Wireless Communication is the means of communication that moves without cable spelled with Mobile Devices. Wireless technology has grown rapidly in the last decade. The principle of this wireless communication using a separate radio channel to communicate with cell sites. Therefore, the developer expects that we can communicate with others without brtemu directly with that person.

2009-11-21T12:00:00.002+07:00

Process improvement software you can use some alternative programs that will be used, such as Griffin, phoenix black box, tornado UFS, JAF, etc. But here I will use the N-BOX tornado as it is popular and easy to use. Before mobile phone repair must meet the requirements, as follows:

1. Battery voltage at least 3.7 Volt (siemens, Samsung, Motorola, and Sony Ericsson => because of type-type voltage is not provided directly by the UFS).
2. Short does not occur on the input voltage. Biloa occur shot must then be corrected before hardware, namely: resistansi check on the phone interface battery engine, 6 Ohm resistansinya maximum, then you flip polaritaskabel avometernya, the phone should show no movement occurs in the needle instructions.
3. Flash interface on the PCB must be clean. If dirty then you must first clear the brush and given a little thiner ago dried.
4. Once the phone is connected to the UFS tornado, after clicked "check" the phone must terdetek, diLCD although there are not any posts tesmode or local mode (especially Nokia). How to detect something like this:

Use the program Ð DCTx tools
connect the phone to UFS tornado
Choose a type mobile phone according to the type of phone will be detected.
Click on "check", DCTx tools will be the "1st Boot OK, WD2/DCT4, UPP: 0 ... ... ....." Error when the phone can not be detected by DCTx tools, then the damage is still on the hardware.

When tidah meet the requirements above then the damage is still possible in the hardware.

BASIC CONCEPT TECHNOLOGY Cellular

2009-11-17T14:32:00.002+07:00

Mobile System is a sophisticated system because this system divide the area in a few small cells. This is used to ensure that the frequency can be extended so that it reaches to all parts of the region in particular so that multiple users can use their mobile phones simultaneously without pause and without falter.
DEFINITION Cellular

In the cellular system, to describe the geographic coverage area digunakanlah representation heksagonal. This is the area that disubut cell (cell). Why not the circle shape heksagonal to describe a cell?
If you describe a cell in the form of a circle, then the cells with each other will not be continuous with each other perfectly. In the cellular system, all areas can dicakupi without gaps cells with each other so that more kurva heksagonal represent, because the coverage area can tergambarkan with rapih and covers the entire area.
Where an antenna will be able to send and receive signals on the three different regions, where each cell is only partially covered only three of the cells covered.
Bebrapa forming an important component of the cellular system is the mobile equipment itself, such as Base Station Radio, Antenna and Base Station Controller will manage lalulintas of some cells that are interconnected with the public telephone network.

AMPS is the first generation of cellular technology. System is allocated in the 800 Mhz band, the network uses circuit terintergrasi a very large and consists of Computer and System Dedicated Switch. At the time this was the inventor of mobile phones because they feel proud to have a very useful invention. Even today's rapidly developing and developed by various circles.

GSM ( Global System for Mobile Telekomunikation )

2009-11-17T14:10:00.003+07:00

GSM is the second generation after the AMPS, GSM was first issued in 1991 and began developing in 1993 with the adoption by some countries such as South Africa, Australia, Middle East, and North America. GSM's growth was due to the use of a digital system so that mengekploitasi allows for the development and use of algorithms and allows the use of digital Very Large Scale Intergration (VLSI). To reduce the cost and handled terminalnya, at the time this was to use GSM features Intelegent Network (network intellect). GSM is a mobile telecommunications system using a digital cellular system. The picture above is one example of a CDMA mobile phones produced by Nokia.

CDMA ( Code Devision Multiple Access )

2009-11-17T14:07:00.004+07:00

CDMA is a third generation (3G), a technology that uses the spread spectrum technique. Unlike the GSM uses Time Division Multiplexing (TDM), CDMA does not provide a specific frequency on the individual user. Each channel uses the available spectrum in full. Conversations in the individual akan encode with the settings of a digital pseudo random. The picture above is one example of a CDMA mobile phones produced by Nokia.

Mobile phone HISTORY

2009-11-17T13:10:00.001+07:00

Mobile phone is a combination of technology combined with the Radio Communications Telephone technology. Phone the first time found and created by Alexander Graham Bell in 1876. While communication with wireless (wireless) is found by Nikolai Tesla in the year 1880 and introduced by Guglielmo Marconi.
Root of the development of digital wireless and mobile starts since 1940 when the car phone technology is commercially introduced. When compared with the current so rapid, in fact this technology has obstacles in the development of more than 60 years. This is because the development of cheaper technologies such as semi-conductor transistor or not yet well developed. Once found it's possible the development of transistor technology became more rapid.

Development of Cellular TECHNOLOGY

With the development of wireless technologies that are rapidly developing technology that is currently without a phone cable (wireless) among AMPS (Advance Mobile Phone System), GSM (Global System for Mobile system), CDMA (Code Division Multiple Access).
