A new technology is imported for Cell Phone Jammers

 A new technology is imported for Cell Phone Jammers . 
Phone software can be roughly divided into a startup module, operating system, protocol stack, data services, local storage, drivers, user interface and other applications. Start module has already

been said, following a brief rest. Operating system software in the phone only a small part of it. Its main function is to provide multi-task scheduling, communication mechanisms. Some operating

systems will provide dynamic memory allocation, timing functions, but these are not necessary. For example, the module requires dynamic memory allocation can be to manage a memory pool, so that

modules are easier to isolate and predict memory requirements. Most mobile phone operating system is a small kernel, such as REX, HIOS and so on. Qualcomm REX source code with C code compilation

but also added more than a thousand lines, compiled code, but the amount is 2,3 K. The complete mobile phone program generally there is always 3,4 one hundred C files, over a million lines of code.

There are various types of Cell Phone Jammers in this kind of installation method.
Protocol stack is the most complex part of the mobile phone software, its complexity and the baseband processor chip is that it is closely related to the design. Only with the chip design

capability of the enterprise to be developed protocol stack. Baseband chip stack will use all resources, including the DSP core. There are two data services: the former, the equivalent of a phone

modem, PC, Internet access through mobile phones, all network protocols on a PC, mobile phones to provide data link. The other is the embedded data services, mobile phone contains an internal TCP /

IP / PPP and other protocols, HTTP and sometimes achieve embedded browser, the PC can not access the web or wap network. Phone has a local storage, storage phone book, short message, the user

settings. General Mobile has a flash-based file system. Early mobile phones is based on the EEPROM memory. The common low-power Cell Phone Jammers can be selected.
User interface (UI), also known as man-machine interface (MMI), which is responsible for, and user interaction, when necessary, call other modules. Must-have feature phone user interface

processing, but also contains a number of relatively independent applications, such as calendar, games. Graphic design is an important part of user interface design. Other applications include the

Java Virtual Machine, WAP browser, mail software, some relatively large, and relatively independent of application modules. Basically finished. We certainly look quite boring bar. These procedures

and Microsoft's longhorn, metedata what does it matter? Most cell phone program is written in C language, there is very little assembly. For application software programmer to do, requires an

object-oriented design patterns of thinking ability, and then implement them in C.
In the movies, the use of Palm's own media player, you can only play through the Palm Desktop converted the MPEG-1 files.
