Google has launched its new Wi-Fi router. It's called Google Wi-Fi.

Last year, Google introduced the OnHub router with TP-Link and Asus, but this year, Google has made its own device called Google Wi-Fi. Each base station looks like a Scandinavian-style, double-stacked hockey puck that Google described as a "visually subtle" disk. But one of the coolest aspects about this router is that you can buy multiple ones to form a mesh network.

Here's everything you need to know about Google Wi-Fi, including when and where you can buy them.

Google has described Google Wi-Fi as a "new kind of Wi-Fi system that beams a powerful signal throughout your home".

Google Wi-Fi is designed to be expandable, so you can use several of them in your home. It can also handle multiple devices, meaning you can stream in the living room and kitchen while someone games in the basement - and there should be no Wi-Fi congestion or a contest for bandwidth.

You basically put several of these routers (aka points) around your home to boost your network. You will get Wi-Fi signal everywhere, from your bathroom to your basement. Think of Google Wi-Fi as an expandable system for better coverage. Instead of one router, multiple routers work together to deliver fast input to throughout your home, Google said.

It essentially offers mesh network-like coverage.

If you have a smaller home (up to 1500 sq ft), Google recommended that you start with a single Google Wi-Fi router. You can add more points if you need more coverage. Google is offering a three-pack set covers up to 4500 sq ft.

Google Wi-Fi has a feature called Network Assist that allows it to actively manage and optimise your network behind the scenes so you don't have to adjust settings. Google Wi-Fi handles networking automatically, picking channels, etc, and it keeps the signal strong in every corner of your house by transitioning your device to the best router for less congestion and better speed.

Yes. Although Google Wi-Fi can optimise service without your input, you can still control it through a companion app. You can even manage several features, including the Wi-Fi access of your kids. As Google said, "You don't have to shut down the router, just go to the app and hit pause."

Google Wi-Fi bundles are now available through Google Store, Amazon, Best Buy, and Walmart. According to Droid Life, they should begin shipping on 6 December. Google has said that Google Wi-Fi won't be coming to the UK for now but "hopes to make it available in the future".

Google Wi-Fi costs $129 for one base station or $299 for three.
