A lot has changed in the Wi-Fi industry, which refers to the ability of radio waves to connect devices to the internet without the need of wires. Now, the biggest search engine has released its Google Wifi, a router that promises speed, efficiency and affordability.

Google Wifi is built on the principle of a mesh Wi-Fi system. The system is made to supply steady internet across multiple devices within a specified range. With the mesh system, there is no need to purchase Wi-Fi extenders, or to put up additional routers should the internet supply gets choked. Google Wifi aims to be the only device router anyone would need for the home.

We've rounded up a review of Google Wifi, and assessment is given per major feature:

Wi-Fi range: A single Google Wifi unit can cover 1,500 square feet; while its three-unit package can cover 4,500 square feet. That's a lot of space given that the average home size in the US is 2,164 square feet with garden included, and 818 square feet for the UK.

Power capability: Each unit has AC1200 2x2 Wave 2 power capabilities and can support 2.4GHz and 5GHz 802.11 a/b/g/n/ac networking. Forgive the jargon. These data just mean that Google Wifi can support multiple users on a multiple input-output level, and can offer greater performance. With the router also 5GHz-enabled, it can be set up and can properly run anywhere in the world.

Security: The device uses the WPA2-PSK protocol. This is the most secure home-use option save for high-level routers that are used in banks and government offices.

Port selection: Each unit is only equipped with two ports: one for internet connection from a modem, and another for WiFi-enabled products that need to be plugged in. A network switch for extension should therefore be purchased if more ports and if USB slots are needed. This limitation may be to avoid overloading the router with too much hard-wired devices that need to be directly plugged in.

Design: The device's design is well thought-of: sleek, savvy and flawless. As all mesh networks have to be displayed (i.e., it cannot be locked in obstructive furniture), it is understandable that Google has made an effort to make the device look good. It can even double up as a unique design for the house.

Price: Google Wifi is sold at $129 per unit, or at $299 for three units. This is way cheaper compared to its competitors Eero ($499 for a three-unit package), and Orbi ($399 for a two-unit package).

Overall, Google WiFi is a great buy for those wanting to make the most of their home internet connections. A video review has also been released by CNET, and its experts agree that Google Wifi is the "best home mesh system yet."
