The issue focused on how to deal with the problem of "unsupported devices" that do not connect to the network. Google's solution, dubbed Project Fi, works on both Wi-Fi and cellular networks, but it requires devices connecting to either network to be registered with the network. The company's developers have been working on an app called Fi-Connect that does that. The idea behind Fi-Connect is that it lets you connect to Fi-Connect networks and download content using the internet while using cellular data.
