Outdoor space will damage the effect of cell phone jammer

Symbian's biggest advantage is that it is designed for portable devices, and limited resources, you can run for months or even years. This is attributed to the protection of memory, Symbian programming description and clear the stack. These functions is used in conjunction with other technologies make the memory usage and minimal memory leakage. Similar technology is also used to increase disk and memory card space. Symbian programming is to use the event-processing, when the application does not deal directly with the CPU, the CPU will be shut down. In the programming language idiom called active objects. Other units of cell phone blocker intelligent system can be built according to this.
The correct use of these technologies will be able to extend the battery life. These technologies enable Symbian C + + has become very professional, and has too high a learning curve. However, many Symbian devices can also take advantage of the OPL, Python, Visual Basic, Simkin is and Perl with J2ME and self-developed Java to use. Symbian OS and Windows Mobile, current palmtops OS, Linux, compete with each other. It also works with the embedded operating system for use in low-end mobile phones compete with each other, while the latter tend to self-developed by various manufacturers. Symbian and embedded operating systems, the advantages of the former is that it's standardized - the device program execution to be able to call each other the dynamic link shared database (DLL) as well as adding architecture (that is, you can install software). The imported elements can maintain the stable operation of cell phone jammer .
These more complex mobile phones to faster development, and sometimes this will offset some of the Symbian C + + difficulty. Symbian and other open operating systems (like Linux and Windows Mobile, while the latter is not open source), its advantage is more controversial. The mobile phone manufacturers and network operators like the Symbian custom flexibility (customisability) rather than the negation Windows. Although these custom flexibility (customisability) makes the integration of Symbian phones is more difficult. Symbian is designed for small devices, making it more powerful ability to more efficient memory management and a more flexible posture. Shut off the software and all detectors of cell phone jammer intelligent system after finishing all commissions.
Symbian basic composition of the lowest order contains the core (EKA1, or EKA2), allows the user to the application requirements of the core things along the user database. Symbian has a microkernel architecture, which defines the minimum functionality necessary for core internal. The microkernel architecture includes scheduling and memory management, but does not include the network and file system support. These are used to provide to the user side server (user-side server). The base layer contains the file server, it is similar to the DOS device display mode (each disk drive has a code, the backslash as a directory defined symbols). Symbian support several different file system. The field strength difference between the indoor space and outdoor space will damage the effect of cell phone jammer .
Contains the FAT and Symbian's proprietary file system, file system generally will not be displayed on the phone. Above the basic alternative system database, which provides the market positioning of the device, the contents of the database contains such a character conversion table, database management systems, and file resources. In addition, there is a huge network and communications subsystem, which contains three main services, namely, ETEL (EPOC telephony), ESOCK (EPOC agreement) and the C32 (serial communication response). Each service has a modular program. For example, ESOCK allow different communication. "PRT" protocol modules, the different forms of network communication protocols, such as Bluetooth, infrared and USB. The customer can turn  cell phone jammer on or off for the instant shielding or unshielding through the remote control function.
