It's still the same. There is no protocol in wifi 11ac for seamless handover unlike mobile networks.Just a small doubt, I had created a makeshift mesh long back using 2 wireless routers by setting them on same SSID and channel. It used to work well if your devices are static, however there was major drawback with mobile devices with real time processes like Whatsapp calling, etc that the connection used to break temporarily when phone switched from one router to another dropping the call. Wifi switching between stations wasn't really seamless. Does Mesh technology fixes it? Or its still the same?
