cell phone jammer can generate shielding magnetic field

cell phone jammer  can generate shielding magnetic field.
The standards are open, so any third-party companies or individuals of interest to EMS development and application of software and services on this platform. However, there is technically not compatible due to a variety of mobile phone brands, in actual use, often only in between the same brands of mobile phones in order to achieve the above transmission, so the practicality needs to be further improved. MMS (Multimedia Messaging Service, multimedia messaging service), also known as MMS, in accordance with the 3GPP standards and development of multimedia information services to the WAP Forum standards. Then, the abrupt radiation can not be formed so that using of the mobile phone can be obligatorily forbidden to guarantee the safety of the above places by using cell phone jammer .The three pieces of mini antennae of can be kept on the host of the mini portable cell phone jammer
Its biggest feature is support for multimedia capabilities, in support of GPRS, CDMA 1X, 3G, EDGE, WAP wireless application protocol for carrier transmission of complex images such as photographs, large-scale charts and music clips, video clips, transmission In addition to the transmission between the phone, you can also transfer between phone and computer. GPRS network coverage than you can use the existing GSM circuit switching (CSD) to transfer, only the GPRS uses packet switching network, the transmission data rate of exchange than the circuit faster. Transmission of data and voice is done with a specific baud rate and modulation system, based on which,  cell phone jammer  can act on the cell phone.
MMS-enabled mobile phone unique is its built-in media editor, users can easily write the multimedia information. If the phone has a built-in or external camera, users can create PowerPoint format or electronic postcards and send them to friends or colleagues. At present, the application service has gradually matured to become a mainstream SMS format. The WAP (Wireless Application Protocol, Wireless Application Protocol) is an open standard protocols, it is composed by a series of agreements, can send information on the network to the mobile phone or other wireless communication terminal. The cell phone will appear situations of net searching, no-signal, no-service system and so on if cell phone jammer  is used.
In mobile communications, due to line capacity constraints and mobile communications standard, the terminal data format, showing the diversity of patterns, making the mobile Internet applications, and can no longer follow some of the criteria in the fixed Internet network, especially in the application layer protocol and services. In order to establish a set of Internet Protocol specification for the opening of the mobile communication system, to promote the development and competitiveness of the mobile Internet Internet business, the WAP Forum came into being. In June 1997, four of the mobile communications industry leaders Ericsson, Motorola, Nokia and wireless Planet launched the WAP Forum, aimed at the introduction of the Internet a wealth of information and advanced business wireless digital phone and terminal, the goal is to produce a applicable different wireless network technologies, global wireless protocol specification for the adoption of appropriate industry standards organizations.  cell phone jammer  can effectively shield all the cell phone signal.
