Google claims it's new WiFi router is better than the one you currently have:
One of the key features OnHub is promoting is the 13 WiFi antennas it holds (Seven 2.4 GHz and six 5 GHz) arrayed in pairs for full 360 degree coverage. While details are thin, instead of one or two omnidirectional antennas, OnHub uses multiple semi-directional antennas in a circular mount.
However, one of the key claimed 'boosts' to performance isn't engineered at all: Google thinks OnHub looks good.
Because of this, OnHub is designed to be installed at eye-level out in open spaces, rather than buried in a cabinet or shelf. Google claims that because you won't hide OnHub, it will provide better signal strength:
It could be a boon for those running WiFi cameras at home. (Like the Alphabet/Google/Nestcam)
Cost is $200, and it is spec'd for Zigbee, so it could potential be used as a hub for smarthome devices. However details are rare on that point for now.
