White Space in the Great White North

There is growing interest in the US for the FCC to look at White Space to enable more options for broadband wireless in rural areas. What is White Space? Last weekend, the Sunday NY Times published an article about wireless services that included this description: "In many areas, not all broadcast [television] channels are in use. The unused channels are "white spaces" of high-quality spectrum that could be made available to local Internet service providers. Unlike the much higher frequency of Wi-Fi, television broadcast frequencies can travel for miles and penetrate walls, providing a much broader range for Internet service." There is a coalition of eight technology companies driving the discussion in the US... more

A Packet of Lies

I've been reading the kerfuffle around Comcast's blocking of various random network protocols with interest. Whilst I remain convinced that blanket "network neutrality" legislation remains just a form of digital gripe water (cures colic for cybernauts), there's clearly a problem. As I previously alluded there's a definite consumer protection issue over what you buy when it says 'Internet' on the tin. So here's tuppence worth of additional input... more

Why a Net Neutrality Law is Not Enough

Once we decide that Network Neutrality is a good thing to (re)enshrine in law, then we need to ask how to do that effectively. One way would be to pass a law saying, "Thou shalt not discriminate." That's the current approach. But network operators will say that they must manage their network, and if, in the course of network management, they were to disadvantage some source, destination, application, service or content, they might be accused of violating the law. So any Network Neutrality law must have a Network Management Exception... more

The Myth of Infinite Bandwidth

Back in the late 1990s I was often asked what I thought would happen if Internet bandwidth was infinite -- what would that change about the Internet itself? Level 3's (LVLT) recent decision to slash prices on its content distribution network and rumors of new multi-terabit cables across the Pacific have me wondering if we are actually getting closer to having infinite bandwidth. But when replying to the infinite bandwidth question I was prone to posing a return question -- what does infinite bandwidth actually mean? more

FON and BT: Wifi Today; Mobile Tomorrow?

A deal announced today between British Telecom and upstart FON allows BT's Internet customers to share their own broadband connections via WiFi and, in turn, be able to access WiFi free at "thousands" (doesn't say how many) of FON hotspots around the world operated by other Foneros... When you buy home Internet access from BT and opt into this plan, you are also buying roaming access at no extra charge. The technology is supposed to assure that the part of the connection which you share is segregated from your own access so that there are no security problems caused by the sharing. more

Enterprise or Public Sector Investment in National Lambda Rail Presents a Unique Opportunity

Sometimes in our worries about the Duopoly, we fail to recognize that some extraordinary wealth of opportunity sits right underneath our noses. National Lambda Rail (NLR) is one such case. About six months ago I wrote in some detail about NLR and what made this entity different from previous attempts at research networks in the US... NLR runs on a philosophy of a user owned and administered research network. Intrernet2 (I2), during the ten years of its existence, has run on the basis of first a Qwest donated backbone known as Abilene and since November 2006 on the basis of a seven year managed services contract with Level 3 Communications. more

Wireless Net Neutrality

To date, most of the discussion on net neutrality has dealt with the behaviour of conventional wireline ISPs. RCR Wireless News is carrying an opinion piece called "Paying for the bandwidth we consume" by Mark Desautels, VP -- Wireless Internet Development for CTIA -- the trade association for the US wireless industry. His article follows up on reports of Comcast cable moving to discontinue internet access service to so-called "bandwidth hogs"... more

Is Bandwidth Infinite? It All Depends…

On August 23 ( while I was in China) a list member Lee S. Drybrugh wrote in jest: I happened to bump into Peter Cochrane stating, "The good news is -- bandwidth is free -- and we have an infinite supply." Next by sheer accident I bumped into this in relation to Gilder, "Telecosm argues that the world is beginning to realise that bandwidth is not a scarce resource (as was once thought) but is in factinfinite." Can anyone explain this infinite bandwidth as I think I am getting ripped off by my ISP if this is true? Craig Partridge then offered what I think is a very good commentary of a difficult question where the answer depends very much on context... more

This Week in the White Spaces

Every once in a while I look in on the white spaces, to see how things are going. You'll recall that the white spaces are unused, non-contiguous ("swiss cheese" ) frequencies between broadcast stations around the county. Commr. McDowell of the FCC has said that initial rules for the white spaces will be released sometime this fall. If the white spaces are made available on an unlicensed basis for use by opportunistic, "smart," low-power mobile devices, entrepreneurial engineers will think of ways to use this wealth of spectrum (300 MHz wide, if fractured) to provide mobile connections to whatever fiber installations are nearest. more

P2P: Boon, Boondoggle, or Bandwidth Hog? (The Dark Side)

Yesterday's post explained how peer-to-peer (P2P) applications use the processing power, bandwidth, and storage capacity of participants in a service rather than centralized resources. This makes such applications generally less subject to catastrophic failure, much less subject to running out of resources (since each new user brings new capacity as well as new demand), and much cheaper FOR THE PROVIDER of the application in terms of hardware and bandwidth required. It's the FOR THE PROVIDER part that's the rub. Let's consider the case of BBC's iPlayer service... more
