make the cell phone unavailable for calling or being called

In hardware design, it can provide the appearance of many different styles, like the use of real or virtual keyboard, can accommodate many of the features on the software functionality, including sharing information with others, browsing the web, transmit, receive e-mails, faxes and personal life such as travel management. In addition, the Symbian operating system for manufacturers in terms of scalability reserved for a variety of interfaces, and the EPOC operating system can also be subdivided into three types: Pearl / Quartz / Crystal, respectively, corresponding to the ordinary cell phones, smart cell phones, Hand Held PC occasions applications. Symbian divided into several major intelligence platform, one is suitable for one-hand operation S60, representative of early products of Nokia 7650,3650; classic models such as 7.61 thousand, Ng. cell phone jammer is especially good in design.
The other hands the operation of the S80 on behalf of the product is Nokia 9210, 9300,9500 also for business users is also very rich with a large number of users. There is also another platform on Symbian UIQ, pen operation, which represents the product is a new machine has just launched Sony Ericsson P802 Nokia 6708 is Nokia's first attempt on uiq. The other new platforms such as S90 is all of us 7710 is a rising star of Symbian. Linux with its free, free, open source advantage, through the efforts of programmers from around the world, coupled with computer giant IBM, Sun and other support Linux in the cell phone operating system market have sprung up everywhere, especially in the many well-known vendors announced support for mobile Linux operating system, Linux will not be ignored. In the hospital, such precise instruments as heart pacemaker, electrocardiogram recorder and so on can be influenced so thatcell phone jammer  is needed. cell phone jammer can make the cell phone unavailable for calling or being called
Because Linux is open source software licensing fees, rich application development of human resources, etc., to facilitate the development of personal and industrial applications. This feature is very important, rich applications to reflect the superiority of the smart cell phone and where the key selling point. From the application developer's point of view, because the Linux source code is open, conducive to independent software vendors (ISVs) to develop the hardware utilization efficiency, more powerful applications, but also facilitate industrial users to develop their own safety, control lability certification system.
