AT&T’s latest home broadband service isn’t DSL or fiber. It’s LTE — Tech News and Analysis: The idea of using a mobile network to connect homes that have either no or slow broadband access is definitely an admirable idea, but it has its limitations. Today’s mobile networks simply aren’t designed for the intense data demands of are increasingly hungry home broadband appliances — they have limited capacity and that capacity must be shared with all of the other users on the network. That’s why the per-gigabyte costs of mobile broadband are so much higher.
An excellent point in this GigaOM article that puts this service in the proper perspective. It's designed for mobile and not premises services. Offering a mobile service to a premises does not make it a premises service.
A few paragraphs down, the article notes:
In fact, AT&T is trying to eliminate the distinction between residential and mobile service entirely.Nice try, but it won't work. Mobile is mobile. Premises is premises.
