Interest group Public Knowledge is rallying against AT&T Mobility’s femtocell terms of service, arguing the carrier’s approach to tallying users’ data consumption runs against the FCC’s net neutrality provisions.

“AT&T has decided that the data from AT&T wireless microcells will not count against the data caps on AT&T DSL or U-verse home broadband connections,” says Michael Weinberg. “This sets AT&T microcell data apart from every other type of data on those connections, including data from a Verizon or Sprint microcell. The message to AT&T DSL and U-verse consumers is clear: if your cell signal is weak and you are worried about your data cap, better get a phone from AT&T Wireless. Simply put, this is an abuse of data caps.”
