Want to make a wifi ‘mesh’ in your house? Google Wifi is available for pre-order in the US at retailers like the Google Store. A single Wifi point retails for $129, and covers homes up to 1,500 square feet. The three-pack, at $299, covers homes up to 4,500 square feet. Google Wifi ships on December 6th, just in time for fast Wi-Fi for all of your holiday guests.
All the Wifi points are connected to each other. Data can take several paths toward its destination — and Google uses their Network Assist technology to ensure that Google Wifi points always choose the fastest route from your device to the internet. This means that you get faster Wi-Fi speeds for things like streaming and gaming.
