Facebook might have a solution to its free WiFi's shortcomings
Facebook knows that a key limitation of its Terragraph gigabit WiFi system is how it falls apart over long distances. Line of sight is kind of a pain that way. So the company has devised a workaround for it with a code framework dubbed Open/R that helps nodes on the network make faster, autonomous decisions about data routing. The way the network operates is that data is transmitted incredibly quickly (by up to 7Gbps) and over short distances from one node to the next. But any obstructions in the visible path between nodes can cause the signal to degrade.
