New Pew Internet Study: Home Broadband 2010

On August 11, as part of the Pew Internet and American Life Project, the Pew Research Center published a new study titled Home Broadband 2010. According to the report, findings are based on data from telephone interviews conducted by Princeton Survey Research Associates International between April 29 and May 30, 2010, among a sample of 2,252 adults ages 18 and older, including 744 reached on a cell phone. Interviews were conducted in English.

Here’s some report highlights:

  • Two-thirds of American adults (66%) now have a broadband internet connection at home, a figure that is little changed from the 63% with a high-speed home connection at a similar point in 2009.
  • Most demographic groups experienced flat-to-modest broadband adoption growth over the last year. The notable exception to this trend came among African-Americans, who experienced 22% year-over-year broadband adoption growth.
    • In 2009 65% of whites and 46% of African-Americans were broadband users (a 19-point gap)
    • In 2010 67% of whites and 56% of African-Americans are broadband users (an 11-point gap)
  • By a 53%-41% margin, Americans say they do not believe that the spread of affordable broadband should be a major government priority.
  • Non-internet users are less likely than current users to say the government should place a high priority on the spread of high-speed connections.
  • A fifth of American adults (21%) do not use the internet. Many non-users think online content is not relevant to their lives and they are not confident they could use computers and navigate the web on their own.
This Pew report is concise, packed with good information and easy to read. You can download a PDF version here.

Back From 2.5 Weeks Of Vacation

I've been trying to get caught up on email over the weekend and hope to get a post up here tomorrow. Lots has been happing in the IT and Communications areas over the past few weeks while I was spending most of the time being a beach bum in Clearwater Beach, Florida.


The Gulf of Mexico was beautiful.

It will be nice to get back to the office tomorrow.

Verizon, Google, the FCC and Real Net Neutrality?

So far Internet policy has stuck to something called net neutrality where no Internet content is favored over any other Internet content. This may be changing though. Last week a number of sources, including the New York Times, reported Verizon and Google were nearing an agreement that could allow Verizon to speed some online content to Internet users more quickly if the content’s creators are willing to pay for the privilege. Here’s more from the same New York Times piece:


The charges could be paid by companies, like YouTube, owned by Google, for example, to Verizon, one of the nation’s leading Internet service providers, to ensure that its content received priority as it made its way to consumers. The agreement could eventually lead to higher charges for Internet users.


Many (including myself) believe big companies paying providers to give their traffic priority would stifle innovative small companies...... the kind of company Google was not that long ago. Others argued (also including myself) that - if carriers can start charging companies to prioritize their traffic - how long will it be before residential customers end up billed in similar ways?


You may ask - as a regulating agency - where has the FCC, with it’s commitment to “transparency” been? Well..... it turns out the FCC has been meeting behind closed doors for the past few months with the big carriers on network neutrality.


Much of last week seemed to be damage control for Verizon, Google and the FCC. The FCC announced they were canceling their closed door carrier meetings and we saw postings like this from Verizon Policy blogger David Fish:


The NYT article regarding conversations between Google and Verizon is mistaken. It fundamentally misunderstands our purpose. As we said in our earlier FCC filing, our goal is an Internet policy framework that ensures openness and accountability, and incorporates specific FCC authority, while maintaining investment and innovation. To suggest this is a business arrangement between our companies is entirely incorrect.


Yesterday, Google and Verizon held a press conference announcing a Verizon-Google Legislative Framework Proposal. Here’s a piece from the Consumer Protections part of the proposal:


A broadband Internet access service provider would be prohibited from preventing users of its broadband Internet access service from--

(1) sending and receiving lawful content of their choice;

(2) running lawful applications and using lawful services of their choice; and

(3) connecting their choice of legal devices that do not harm the service, facilitate theft of service, or harm other users of the service.


The Wireless Broadband piece of yesterdays Verizon-Google proposal is also interesting:


Because of the unique technical and operational characteristics of wireless networks, and the competitive and still-developing nature of wireless broadband services, only the transparency principle would apply to wireless broadband at this time. The U.S. Government Accountability Office would report to Congress annually on the continued development and robustness of wireless broadband Internet access services.


The backlash continues. Here’s commentary after the Verizon-Google press conference from Karl Bode at DSL Reports:


Nothing said today (Monday) changes the fact that this policy framework is very much focused on creating a weak, self-regulatory policy system filled with loopholes instead of real neutrality consumer protections.


As the regulating agency, the FCC needs to step it up and get control of this.

Pay Phones - 25 Cent Local Calls

As I travel around I usually have my eyes open for pay phones and when I do find one I usually end up taking a picture since we're seeing fewer and fewer of them. Here's a shot of a pay phone carcass I walked by in Orlando last week.

I've had a cell phone for at least 15 years now and cannot remember the last time I used one of these.

LTE and WiMAX - What's the Difference?

Yesterday, at the Convergence Technology Center sponsored Working Connections 2010 Conference In Frisco, Texas I had some time at lunch to talk about emerging mobile technologies. With only ten minutes I had to carefully pick what I wanted to discuss and decided on bandwidth and access (Surprised?!) with a focus on the two current emerging 4G technologies - LTE and WiMAX.

Lots of questions and with the time limit (people had to get back to their workshops) I did not get a chance to answer too many. People were asking about the detail differences between LTE and WiMAX. For example, is one technology better than the other? Why would one company decide on LTE while another decides on WiMAX to deliver next generation services? You said they are very similar - what makes them different?

Here’s some quick answers:

LTE will be/is the 4G technology of choice of the larger mobile carriers like Verizon Wireless (Rolling out LTE this year) and AT&T Wireless (scheduled to start LTE rollout in 2011). These carriers already have FDD spectrum and the money to buy more spectrum. The carriers will also tell you that LTE more easily supports backward compatibility with earlier cellular technologies.

WiMAX will be/is the choice of carriers with TDD spectrum and also makes sense for for greenfield situations where backward compatibility is not needed.

LTE uses FDD spectrum and WiMAX uses TDD spectrum - what’s the difference between FDD and TDD? Here’s a quick explanation from three-g.net:

Frequency Division Duplex (FDD) and Time Division Duplex (TDD) are the two most prevalent duplexing schemes used in broadband wireless networks. TDD is the more efficient scheme, however, since it does not waste bandwidth. FDD, which historically has been used in voice-only applications, supports two-way radio communication by using two distinct radio channels. Alternatively, TDD uses a single frequency to transmit signals in both the downstream and upstream directions.


Basically, FDD (LTE) uses two channels and TDD (WiMAX) uses one channel for two-way communications.

Which technology will dominate? It looks like LTE but..... there are issues with expensive and crowded spectrum. There’s a lot more TDD spectrum available than FDD spectrum and TDD spectrum is cheaper. Wouldn’t make sense to develop a version of LTE that could use TDD spectrum? It sure would and that is what TD-LTE does - it uses TDD spectrum.


Does it work? Yes! Yesterday, Ericsson ad China Mobile demonstrated an end-to-end TD-LTE solution that achieved a single user peak downlink rate of 110Mbps. China Mobile has also announced it will launch 8 TD-LTE test networks worldwide in 2010.
