Without Anonymity
Mobile operators often stress the protect ability of their connection using the principles of digital coding. However, regular using of mobile communication makes your information widely available. First of all your location can be tracked by satellite. Simple stationary phone can fix only the call itself. Mobile handset is considered to be a private thing. Every mobile number is registered. Besides, it sends and receives radio signals, so you are constantly carrying a small radio beacon with you. Fortunately, this function is used only by special service departments. Moreover, every mobile operator company has security department that is obliged to give all required information to law machinery.
Information transmission through short SMS messages or media MMS messages becomes more and more popular. But such messages don't go directly to their destination. They are kept at the server of mobile operator for some time. Thus, only communications workers are responsible for their anonymity and destruction.
Mobile operators even offer pre-paid anonymous services, but still they will be registering the calls and messages from your personal number.
Some technical specialists are even able to tap mobile conversation. Of course, it requires certain technical equipment. The principle is the following: the device that imitates the work of base station is located between the mobile phone owner and the nearest station. Thus, the phone conversation is intercepted. Such device is using the same radio frequency with mobile operator that is highly prohibited by the law. To prevent the interception of mobile conversations mobile operators introduced the three generation (3G) technology. It is using other methods of coding and protocol exchange.
