Mounting public pressure has moved Verizon to change their mind about throttling speeds for their unlimited data plan mobile customers. There has been quite a bit of press related to poor customer satisfaction and even public letters between Verizon and the FCC regarding the data throttling announcement.
Today, the FCC defines broadband as a connection with download speed of at least 4mbps and an upload speed of at least 1mbps. This definition was an upgrade from the previous definition of 768kbps prior to 2010. As of May 2014, the FCC has been inquiring and seeking comments on increasing the definition to between 10mbps and 25mbps.
