Previously, I've written about how the success of the MVNO (though not without its problems) demonstrates how an Open Access-like business model can work in a wireless context. The underlying carrier, such as Sprint or Verizon, can sell access to its network at wholesale rates to a company like Virgin Mobile, which then markets to consumers. This model can be and is a success both for the retailer and the wholesaler. MVNOs are not perfect. more
Today's Wall Street Journal had an interesting article (subscription required) on the current state of the wireless walled garden. It cites several recent clashes between handset vendors and cellcos over the extent to which consumers can use their phones to access non cellco content. From the article: "At stake for consumers are what services will be available on their mobile phones and whether they're free or cost a monthly fee. The wireless Web is taking off more slowly in America than overseas, and one reason is that U.S. carriers tightly control what applications are available on mobile devices..." more
I've been involved with VoIP technology since 1996. I've been a public advocate for wideband audio at least since 1997. And I've admired and supported a variety of companies using VoIP to provide innovative services and new user interfaces. But reflecting on the past decade, the only globally significant impact of VoIP has been on prices (by fostering arbitrage). Most VoIP telephony services are just digital POTS... more
Ed Richards, Chief Executive of Ofcom, was at Columbia today... NN (Net Neutrality) debate does give us insight into importance of disclosure to consumers -- consumers should be able to switch providers, and they should know which ISPs are making prioritization decisions. This should be an obligation of suppliers to communicate this information to consumers. In particular, he says that Ofcom is actively exploring whether network operators whose traffic shaping activities change materially should have to tell consumers -- and if these changes are significant consumers should be allowed to break their contracts with the provider without penalty... more
What economic and social factors are shaping our future needs and expectations for communications systems? This question was the theme of a joint National Science Foundation (NSF) and Organisation for Economic Co Operation and Development (OECD) workshop, held on the 31st January of this year. The approach taken for this workshop was to assemble a group of technologists, economists, industry, regulatory and political actors and ask each of them to consider a small set of specific questions related to a future Internet. Thankfully, this exercise was not just another search for the next "Killer App", nor a design exercise for IP version 7. It was a valuable opportunity to pause and reflect on some of the sins of omission in today's Internet and ask why, and reflect on some of the unintended consequences of the Internet and ask if they were truly unavoidable consequences... more
Susan Crawford, seeking to learn from Korea and Japan, identifies three routes towards broadband competition... Facilities based competition: Still waiting for that mythical third wire, or perhaps some unused, unlicensed TV spectrum, but not holding my breath. (Broadband over powerline? It is such an encumbered technology that it is its own barrier to entry.) Wholesale access: Been there, tried that, but the Bells wouldn't unbundled elements... more
With everyone talking about network neutrality, with all the heat, it didn't feel good to have to be in NY today and miss the goings-on in Washington. I watched part of the late afternoon markup session online, with Rep. Barton sounding awfully effective as he marched steadily through Title III -- quickly taking votes, soothing congress people who were suggesting soon-to-be-rejected amendments, and sounding confident. The only substantive work I heard was the rejection of an amendment that would have left in place all state laws that regulate the subjects of the bill -- like mini wireless networks. But the real news had already happened... more
VoIP is here to stay. In fact many incumbent telecommunication carriers have started offering VoIP service for sometime and several new VoIP service providers have emerged. Aside from issues such as quality of service, the aspect of security, or lack thereof, is misunderstood by some of the VoIP service providers. This purpose of this article is to discuss two of the most well known attacks that can be carried out in current VoIP deployments. more
Rob Hyndman has a pointer to Mark Cuban's latest: Think the Internet Will Replace TV? Think Again. Cuban's post can be summarized as: Today's broadband networks are too slow. The insatiable appetite for on-demand rich media content will soon overwhelm them. Telco's aren't putting in upgraded networks quickly enough to meet that demand. Cuban also provides some facts and figures to back up that claim. In the comments, readers have a number of viewpoints, including the view that Mark has ignored cable, and that cable can provide the required speeds and feeds... more
Despite rather rapid growth in broadband access, the U.S. is falling further and further behind other countries -- we're now ranked #16 in the world. What's slowing the U.S. down? Two threads dominate U.S. broadband policy debate today. The first focuses on traditional telecom regulation -- reciprocal compensation, universal service, e911, and CALEA (wiretap capabilities). The second focuses on "Internet freedoms," i.e., guarantees that your broadband access provider won't block or inhibit specific applications like VoIP. more
