Specialists from the National Research University of Electronic Technology (MIET) have created a portable system to provide communication in areas where there is no signal from cell towers. This was reported by the university's press service.
The innovative system includes compact portable devices that amplify and transmit signals to each other. They are capable of maintaining communication and operating without recharging for 5-6 hours.
We have created a prototype device based on a microcontroller that can, in certain cases, upon pressing a button or triggering a sensor, transmit a distress signal with coordinates and a message about what is wrong to all other nearby devices. We have manufactured 20 devices that can move relative to each other at a distance of up to 100 meters.
The development will help to always be in touch in hard-to-reach places (mines, tunnels) during rescue operations. The system will also make it possible to transmit information in the absence of mobile and satellite communications.
According to the author of the project, the system for maintaining communication is based on the principle of «хлебных крошек».
On your way, you leave a device every 500 meters, which form a telecommunications network between themselves and allow you to contact any remote user.
He also emphasized that if one device for maintaining communication fails, it is easy to replace it with another. In the future, scientists plan to integrate different video image recognition systems based on MANET networks (wireless networks consisting of mobile devices).
Earlier, www1.ru reported that fiber-optic communication lines will be laid in eight districts of Kamchatka.
