Google OnHub teardown

Google’s latest gizmo – the OnHub – promises a new way to Wi-Fi. But is this just a router? Or the prophesied future hub of an automated home? We dove in to see if the OnHub does more than just what’s on the tin.
With a boatload of antennas, elegant design, and a huge speaker (of all things), this is like no router you’ve ever seen. There’s certainly experimental tech in here. But the speaker is just a speaker, not the Echo's magnificent sound chamber. And the lack of microphones makes us wonder if the real home automation hub might happen in the upcoming ASUS version. Specs aside, do we think the OnHub was on-point in repairability? Not quite. And that’s why we gave it a 4 out of 10 on the repairability scale.

Google OnHub Teardown highlights:

Tucked just beneath the speaker grille, we find the highly anticipated congestion-sensing antenna. Once inside, there are 14 antenna cables—that's one more than we expected, what with OnHub’s advertised "13 antennas (six 2.4GHz antennas, six 5GHz antennas, and a congestion-sensing antenna)." A little careful sleuthing finds the extra antenna is included for the upcoming 802.15.4 ZigBee networking support.

The OnHub’s 3-watt speaker uses ultrasonic tones to configure Android devices running Google's companion app. Without any volume controls or obvious microphones, it seems this Hub isn’t destined to be a music machine.
