The document discusses the networking capabilities and principles of One Laptop per Child (OLPC) laptops. It describes how OLPC uses WiFi networking and builds a mesh networking layer on top to allow collaboration between students. The mesh networking extends the range of WiFi and allows students' laptops to communicate directly to share documents and interact, without needing an internet connection. It compares mesh networking to traditional WiFi and how both use the same radio spectrum but mesh extends WiFi connectivity and does not replace it. Schools would still use WiFi access points connected to servers while the laptops can communicate via their built-in mesh networking.
