On Friday, July 13, I was a guest on TWiT Specials on the This Week in Tech Network, discussing bandwidth caps with Dane Jasper, Reid Fishler, and Benoit Felten. Hosted by Tom Merritt. It was a very good discussion over the course of one hour.

This is a guest post, authored by Jay April. Jay is a strong supporter of local authority and community media. He is a documentary filmmaker, video journalist, and new media innovator who now happens to find himself running a community TV and radio station in Maui, Hawaii. There is a new land grab in Hawaii whereby the government is giving away valuable public land to private business without getting anything in return for the people. Sound familiar? It has happened before in Hawaii – with agriculture, with beaches, with water and now, with the public airwaves. This time the difference is that the land in question is in the form of public electronic real estate, the electromagnetic spectrum. These are the frequencies you pay for to watch cable TV, use the internet or talk on the phone. Most people don’t know this, but in exchange for using public rights of way - airwaves, telephone poles, electric wires and underground conduits - cable monopolies like Oceanic Time Warner have to pay “rent” in the form of community access channels like Olelo on Oahu, Akaku on Maui, Na Leo on Big Island and Hoike on Kauai. Now, because of new technology, the frequencies or space these channels occupy have suddenly become extremely profitable to cable companies. (Not unlike how lands once granted to indigenous people by treaty became more valuable once minerals were discovered.) That is why Time Warner wants to take over this public property and move these channels to inferior locations while vastly reducing the amount of non-commercial electronic real estate. That is why, if you are an Oceanic Time Warner Cable subscriber, channels are disappearing from your channel line-up altogether, or re-appearing someplace else. So far, instead of holding your land in public trust, the state is falling for the Time Warner plan - hook, line and sinker. Maybe that is not such a bad thing after all. Oceanic says this techy move will free up more space on the cable for them to bring us all kinds of goodies like High Definition (HD) channels, video on demand channels, enhanced services and the holy grail of faster, better and more affordable internet for all. That’s a good thing, right? We all want to believe. We really do.

Far too many people seem to think that when they go to Speedtest.net to test their connection, they get a number that has any bearing on reality. For most of us, it simply doesn't. This is true of other large tools for measuring connections. And it has important policy implications because the FCC contracted with a company called Sam Knows to measure wireline speeds available to Americans (I'm a volunteer in that project). Sam Knows explains :

SamKnows has been awarded a ground breaking contract by the Federal Communications Commission (FCC) to begin a new project researching and collecting data on American fixed-line broadband speeds delivered by Internet Service Providers (ISP's) - until now, something that has never been undertaken in the USA. The project will see SamKnows recruit a team of Broadband Community members who will, by adding a small 'White Box'’ to their home internet set up, automatically monitor their own connection speeds throughout the period of the project.

Unfortunately, SamKnows appears to be documenting fantasy, not reality. To explain, let's start with a question Steve Gibson recently answered on his amazing netcast, Security Now (available via the TWiT network). A listener asked why he gets such large variation in repeated visits to Speedtest.net. Steve answers the question as an engineer with a technical explanation involving the TCP/IP protocol and dropped packets. But he missed the much larger issue. Packets are dropped because the "pipes" are massively oversubscribed at various places within the network (from the wires outside you house to those closer to the central office or head end). What this means is that the cable company (and DSL company, to a lesser extent) takes 100Mbps of capacity and sells hundreds of people 20Mbps or 30 Mbps or whatever. Hence the "up to" hedge in their advertisements. The actual capacity you have available to you depends on what your neighbors (cable) or others in the network (DSL) are doing. Dropped packets in TCP result often result from the congestion of high oversubscription ratios. This gets us into why Speedtest.net and Sam Knows deliver fantasy numbers.
