The article would have been more complete if it had noted that Google is attempting to be an 'SAS' database provider for the 3.5GHz band. See http://www.fiercewireless.com/tech/story/google-touts-spectr...

So what Google is saying is "LTE doesn't work well with Wi-Fi in the 5GHz band, so you should use the 3.5 GHz band. And since we are not evil, we won't mention that you need to go through yet another Google service to use the 3.5 GHz band."
