The deal offers another clear indication of Amazon's ambitions to control as many aspects of the connected home as it can. It already makes Echo smart speakers -- which dominate the US market -- as well as Fire TV streamers and even an Alexa connected microwave. With Eero, it is pushing into Wi-Fi networking equipment, too. That equipment has likely become even more important for Amazon, since Wi-Fi is the foundation for all the smart-home gear Amazon is selling.

Google, Amazon's main rival in smart home, already sells a competing -- and much cheaper -- system called Google Wifi.
