eero's is ramping up beta testing of its mesh Wi-Fi system.

An email blast to eero customers today said it is still in beta testing and contained no ship date update.

Specifics noted were:

• Systems are installed in 50 employees' homes
• Field beta is being expanded to an additional 200 homes
• Hardware design is "locked"

eero added "It’s now all about fine-tuning our software and app while ramping manufacturing".

The rest of the email contained claims of Wi-Fi speed improvement of 300 to 400% "relative to testers' old equipment. There was also a nod to Google's OnHub announcement with some competitive positioning of eero's multi access point solution vs. Google and all other single router solutions.
