It isn’t officially announced, but earlier today Google posted a teaser GIF about upcoming product availability on their French Google+ page. The meaning of the image wasn’t entirely clear since it’s just an animation of some buildings growing out of the ground, as a bubble in the center reflects waves around. However, since the filename was “Google Wifi #3.gif,” I don’t think it’s too much of a stretch to make a guess.
Google Wifi may be coming to France on Monday was written by the awesome team at Android Police.
