100 Mbps Access Will be Common by 2020. Ubiquitous 1-Gbps Access Might Take 10 Years

Policymakers, policy advocates and many bandwidth-dependent interests are calling for either 100-Mbps or 1-Gbps Internet access as a “standard” U.S. reality by 2020 or so. Some will doubt that is feasible. As daunting as that objective sounds, history suggests the goal is achievable.

In fact, some relatively standard forecasting techniques suggest the 100 Mbps target is inevitable. Perhaps the only question is when the 1-Gbps speeds might be common.

Give it a decade. In 2002, it is hard to remember, only about 10 percent of U.S. households were buying broadband service. A decade later, virtually all Internet-using households were buying broadband access service.

Researchers at Technology Futures continue to suggest that 100 Mbps will be a common access speed for U.S. households by 2020, for example.

In 2009, Technology Futures predicted that, in 2015, about 20 percent of U.S. households would be buying access at 100 Mbps, about 20 percent at 50 Mbps, and something more than 20 percent will be buying service at about 24 Mbps.

That might have seemed a bold forecast back in 2009, but Technology Futures uses a rather common method of technology forecasting that has proven useful. In fact, Technology Futures has been relatively accurate about access speeds for a couple of decades, at least.

The 2009 forecast by Technology Futures furthermore seems to be a reasonable approximation of reality. Technology Futures had expected that roughly 20 percent of U.S. households would be buying 1.5 Mbps service by about 2010, another 20 percent would be buying 24 Mbps service, while 40 percent of U.S. households would be buying 6 Mbps service.

The Technology Futures estimates of 2009 seem to match other data reasonably well. An Akamai study suggested that typical U.S. access speeds. were about 4 Mbps, on average, in 2010,

Separate test by Ookla cited by the Federal Communications Commission show widely varying speeds in different cities, but running generally from 8 Mbps to 12 Mbps in 2010.

Recall the Technology Futures forecast that 40 percent of U.S. households would be buying services of about 6 Mbps, with 20 percent buying 24 Mbps and 20 percent buying services of about 1.5 Mbps. Average them all together and you wind up somewhere between 6 Mbps and 12 Mbps.
But the forecast of 100 Mbps by 2020 requires movement of two orders of magnitude in less than a decade, and three orders of magnitude to reach 1 Gbps.

You can count Netflix CEO Reed Hastings as among those who think the typical U.S. household will be buying quite a lot of access capacity by 2020. The difference is that where Technology Futures believes 100 Mbps would be typical in 2020, Hastings thinks 1 Gbps could be a reality.

Back when modems operated at 56 kbps, Netflix took a look at Moore’s Law and plotted what that would mean for bandwidth, over time.

“We took out our spreadsheets and we figured we’d get 14 megabits per second to the home by 2012, which turns out is about what we will get,” says Reed Hastings, Netflix CEO.“If you drag it out to 2021, we will all have a gigabit to the home.”

The difference between the Netflix expectation and that of Technology Futures probably can be accounted for by the fact that Moore’s Law applies to only a relatively small amount of access network cost. Physical costs other than semiconductors account for nearly all access network capital investment and operating cost, and none of those other cost elements actually follow Moore’s Law.

The point is that, whether government policies and incentives are in place, or not, it is highly likely typical access speeds will be relatively widely available by 2020 or 2025.

With most things broadband, a decade is plenty of time to bring surprising speed increases into common and typical use.
