When I lived with a herder family in Mongolia, the sources of information from the outside world were a small solar-powered radio and the presence of travelers and visitors.
Herder families in Mongolia are very isolated, and need to create their own sources of power. The family I lived with had a small solar panel that they placed on top of their yurt as well as a tiny windmill. These were hooked up with wires to a large battery inside the yurt, which is their only source of power for their radio and mobile phone.
