Google Wifi is a mesh-capable wireless router designed by Google to provide Wi-Fi coverage and handle multiple active devices at the same time. This is Google's attempt to make a completely in-house router, as compared to the Google OnHub routers made. Google Wifi was announced at the #MadeByGoogle event on October 4, 2016.
Google Wifi is set to be released on December 5, 2016. Right now it can be purchased at Best Buy, Walmart, Amazon or in the Google Store.
