Gigabit Wi-Fi offers no such guarantees. Championed by both Starry and Facebook's Terragraph project, the new technology uses higher frequencies to send data through the air at rates as high as 7 Gbit/s. But that speed comes with a price. The smaller waves are easily absorbed by moisture or flying objects, so any single link could degrade or drop out at any time. Since a given connection might rely on half a dozen different links, shepherding data through the system requires routing programs that can make smart decisions at almost instantaneous speeds.
