Title: A MOBILE SYSTEM FOR ACCESSING THE INTERNET IN EMERGENCY CONDITIONS
Abstract: The invention refers to a system easily transportable by a team of rescuers to bring or restore connectivity to the Internet in a geographical area where said connectivity is absent or has failed, for example due to a natural disaster. The system according to the invention comprises a plurality of electronic devices interacting with each other so as to form a wireless telecommunications network of mesh topology. More precisely, each of said devices comprises a first antenna for the transponder of radio-frequency electromagnetic waves by means of the Wi-Fi technology. It is through said Wi-Fi antennas that the devices that make up the system connect to each other in such a way to form the mesh network. At least one of the devices in the system is also able to connect to the Internet. Thanks to this and to the formation of the mesh network, each device, through a second Wi-Fi antenna, is able to create a bubble of connectivity to the Internet in the immediate vicinity of the same. Through the connectivity bubbles created by the second antennas, a rescuer can access the Internet wirelessly..
