OpenSignal: “Public Wi-Fi has transformed the way we stay connected, enabling a whole generation of start-ups to be created in cafes and other ad-hoc workspaces. Cafes are now seem almost as likely to publicly advertise their Wi-Fi network as they are the quality of their coffee. As we grow more demanding of Wi-Fi, expecting to be able to watch television or skype friends on publicly accessible connections, knowing that a certain location offers Wi-Fi is no longer enough. We know which cafes have Wi-Fi, we know which stores have Wi-Fi, and we know that the hotels we visit have Wi-Fi; what we don’t know is how fast that Wi-Fi will be.”
