Today, the number of GSM subscribers has exceeded one million people. The very name of the GSM standard, Global System of Mobile Communications (General System of Cellular Communications), has taken on a new meaning. The GSM standard has been assigned one of the main roles in the evolution of communication systems. It is closely related to all modern digital network standards, primarily ISDN (Integrated Digital Network Communications) and IN (Intelligent Network). The main functional elements of GSM are included in the international standard of the global system of the third generation of mobile communication, UMTS (Universal Mobile Telecommunications System), which is currently under development. A model for sending an audio message to a mobile phone via a GSM base station is proposed to warn of impending danger using multi-functional towers installed with sensors in areas where there is no cellular connection.
