One might argue that these limits are imposed because it is a cellular network. This is partly true. But this view ignores the larger looming problem. Our regular non-cellular Internet is about to be engulfed by a torrent of data demands that will test its bandwidth beyond endurance. In 2008, AT&T made a dire announcement. It stated their estimate that without investment, the Internet's current architecture would reach its limit of capacity by 2010. Now it is not clear if this is purposely alarmist, so AT&T and others (Verizon, Comcast, etc.), could raise their rates to cover this "investment." The growth, however, is not untrue.
The surge in online content is at the center of the most dramatic changes affecting the Internet today," he said. "In three years' time, 20 typical households will generate more traffic than the entire Internet today.The predictions by AT&T was that there would be a 50-fold increase in broadband traffic by 2015. AT&T stated that to counter this, they would be investing $19 billion dollars to maintain and upgrade its backbone.

Here is a video explanation of how the Internet works and sends traffic.
All of the events happening in these videos are happening at blinding speeds.
Nielsen's Law Of Internet Bandwidth
Internet2/National Broadband/NGA (Next Generation Access)
This video was done for Australia, but the principle is still the same for the United States and anywhere in the world where this is being implemented. There is no question that as the Internet grows, video streaming on demand will be the norm. This is the visible prediction of what at least some of the demands for additional bandwidth are. There may be additional demands from new innovations that we have no way of predicting right now, but which, are surely coming. This video streaming is part of a term called "real time entertainment." This category accounts for 43% of peak traffic in the U.S.
One critical element of this new fast network is the what is termed the last 1,000 feet by the telecommunications industry. This refers to the average distance between the home and the fiber optic cable. This distinction is essential due to the fact that most Americans and people around the world, have those last 1,000 feet covered by twister pair copper wire, such as was used by the telephone company, called POTS (plain old telephone service). This cooper wire, does not have the bandwidth of fiber optic cable. With this National Broadband Plan there is a push to take the fiber optic cable the last 1,000 feet to the subscribers home, known as FTTH (fiber optic to the home). This is the technology behind Verizon's FIOS and Comcast's All in one package of TV, Phone and Internet combined. Only fiber optic can deliver this kind of combined bandwidth. Sometimes, the term FTTX is used. The X is simply a variable that can stand for the home, business, curb, basement, node or premises. In terms of the speed there are varying degrees of difference, with the ultimate speed gain being FTTH. There are many technical details we are not including here, which may be investigated in the above cited link (FTTX). The ultimate goal in speeding up the Internet is to get rid of copper wiring throughout the entire network and using exclusively fiber optic cable. Economically, the costs of fiber optic cable have been going down, while, copper wire has been going up.
How much faster is fiber optic cable than copper wire? Fiber optic is at least 1,000 times faster. This of course presents a big problem. If users now have the ability to watch TV, movies, or use other data-intensive services, they will. This means that the Internet Service Providers will have to keep up with the dramatic increases in bandwidth. Wi-Fi, WiMax and LTE are all wireless attempts to match National Broadband Plan. There is a connection between the plans for an electrical smart grid and this next generation access Internet. The implementation of a electrical smart grid assumes a NGA network.

Why is South Korea ahead of the United States? One report, from CNN, links it to higher competition, with more companies offering service than in the United States.
