Gaping Hole in Models for Using Spectrum Efficiently

In February, the FCC's Office of Strategic Planning and Policy Analysis published three studies (1, 2, 3) on spectrum licensing and spectrum utilization. Thanks to Nick Ruark for pointing them out... Reading on I was struck by a gaping hole in their assumptions. more

Google and the White Spaces

The white spaces proceeding is the next big opportunity for experiments in alternative ways of providing wireless highspeed internet access... A key advantage of unlicensed spectrum is that experiments in new technology can be carried out without asking the permission of spectrum licensees. To date, we have made very little spectrum available for unlicensed use and experimentation. The FCC has the discretion to decide whether the digital television "white spaces" may be used on an unlicensed basis... more

Google’s Gigabit Gambit

Want a gig (1000 megabits per second) of Internet access bandwidth? Google says you could have it by the end of next year "from Manhattan to rural North Dakota (sic, I think they meant Vermont)" if their proposal to the FCC is accepted forthwith according to CNET's newsblog. Not only a gig but a mobile gig, accessible by cellphone or roaming computer -- no fiber required. Sound too good to be true? -- it isn't, IMHO! Engineering is not the problem... more

700 MHz Auction Winners: Why Block C Matters

Today the FCC announced the winners of the 700 MHz auction -- and you can see from pp. 62-63 of this document that Verizon won Block C. (Block C was set up in two nationwide paired blocks of 11 MHz each, which were auctioned off in very large geographic areas -- 12 licenses, each covering a "Regional Economic Area Grouping". Verizon won seven of the twelve licenses, covering all of the US except Alaska, Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.) Why does this matter? more

Broadband Access: What Should We Regulate?

Network Neutrality is a hot topic in the US. The FCC held hearings in my neighborhood recently (while I was in Asia). Now I see Professor Susan Crawford will be testifying next Tuesday at a House Judiciary Committee hearing on "Net Neutrality and the First Amendment." I look forward to her remarks, but I worry that the whole discussion will be focused on "IP Pipes," that is connectivity at network layer 3. This distracts us from the fundamental problem... more

It’s March Madness Time and I Want My IPTV!

IPTV is on the horizon. Maybe I watch too much basketball, but the first thing I pictured was turning my flat screen into a big PC-like monitor with multiple windows showing several games, and perhaps even checking email and trying to do a bit work in another (admittedly much smaller) window. You could drag and drop, expand or shrink the games to whatever size you wanted just like you do on a PC with applications. Since the source video could come from different geographical regions in the country, you could catch the NCAA game they are showing in your local region while also watching another game from another region... For some, IPTV is a reality. But for the most part deployments are limited. more

Why Telcos Don’t Get Networks

I've posted to SSRN my paper on why most telecom companies, even though they operate networks, don't appreciate the fundamental business dynamics of network structures. This will be a chapter in a book Wharton is publishing on network-based strategies and competencies. In the paper, I describe two views on telecom and Internet infrastructure... more

The Perfect Phone

Lee Dryburgh initiated a great thread in the Emerging Communications public group entitled What would your perfect phone be? There are 14 messages there at this moment with a lot of good ideas, but my first thought was the term "phone" is too limiting. Indeed, some of the correspondents' ideas also go far beyond the idea of a telephone. Here's what I want and fully expect to see, eventually. more

On Comcast and Net Neutrality: Shouting Fire in a Theater

The Comcast traffic shaping case has stirred up passionate debate. Net neutrality proponents are calling for Comcast's head on a platter. The common argument is that Comcast's policy may stifle innovation and competition. If a service provider is allowed to exercise unregulated discretion in how it treats subscriber traffic, it is a slippery slope toward anti-competitive practices. Net neutrality says keep your hands off. Some are preaching net neutrality as if it were an inalienable human right like freedom of speech... more

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more
