Eero, a relatively new player in the Wi-Fi game, is introducing Eero Labs to give its customers a chance to try out new features on its mesh Wi-Fi system before they go mainstream. Dubbed an innovation playground for your Eero network, customers will have a peek behind the scenes of Wi-Fi technology. Make sure you have the latest version of the Eero app (2.17 or higher on Android or 3.8 or higher on iOS) though, if you want to be the first to know about new features. 

Eero was one of the first companies to bring mesh Wi-Fi into the mainstream. It released its first multi-unit mesh system in 2014 to help people seamlessly expand Wi-Fi coverage in larger homes. You can buy its newest three-piece mesh system (one main router plus two Beacons) for $400.
