Now, in message number four afirma que " the mesh network of an OLPC, that didn’t need the CPU for transmitting network traffic, so still worked when the OLPC was „sleeping“ had a range of up to 4 kilometres". [https://mastodon.la/@jwildeboer@social.wildeboer.net/113137659879899521]

The question is the following: what kind of technological devices were those computers equipped with that allowed the transmission of information up to a radius of action of four kilometers?

Do you have any specialized references that would allow me to go deeper into this technical aspect that you mention?

Note: the image that I attach is from a computer acquired in La Guajira, Colombia, known as “Canaima” of second generation and I have it for two years. They have MX-Linux installed and it works great.
