Eric, they didn't fiddle around with the legacy railway. They built a road network for cars and a whole new world around it. From the gas station, to the guy who changes your tire, to the policeman who fines you, the road motels, to the companies who build the tunnels, bridges etc etc etc.

We have the technologies. We just need to build it and give legacy a second class funeral. It is not happening due to the lobyying power of the incumbents. The same that happened when the telegraph didn't want to move over for telephony.

The State as Netwatcher

EXCERPT:
"Another key factor was that the government, the parliament (Riksdag), and the Kungliga Telegrafverket (the state telegraph agency, which had been formed in 1853) initially remained passive. When the telephone was introduced, there was already a widespread international telegraph network.

Telegrafverket did not see the telephone as a competitor. Telephone calls were something appropriate for local communication. For great distances, a telegraph was needed. However, Telegrafverket did build a few small, local telephone systems, mainly for the needs of government agencies.

When some private telephone companies wanted to build regional telephone lines, Telegrafverket tried to prevent them, at first with limited success. In 1888, Telegrafverket proposed a special telephone tax to finance the losses in its telegraph business that it believed telephony was causing. The Riksdag and the government rejected this proposal. In the same year, though, Telegrafverket did achieve an important political victory. SAT had applied for permission to build a telephone line linking Stockholm, Gothenburg, Malmö, and Sundsvall. Telegrafverket protested and won the government’s support. SAT’s application was turned down, and Telegrafverket received permission and funding to build a line between Stockholm and Gothenburg. In conjunction with this, Telegrafverket also established a general telephone network in the capital.

Around the year 1890, Telegrafverket [??] changed its strategy: to achieve total control over the telecom system by buying up the private operators. With this, Telegrafverket won quick victories everywhere in Sweden except Stockholm. SAT had quickly passed Stockholm Bell and become the dominant operator. In 1888, SAT had bought a majority stake in Bell and integrated the two networks. So, for the next 30 years SAT and Telegrafverket struggled over who would determine how the telephone system in the capital would be organized.
The number of subscribers in the two networks continued growing a pace, and Stockholm maintained its position as a leading city in international comparisons of telephone density. Competition curbed prices and spurred product development, for example so that several types of subscriptions were offered.
At the turn of the century, Telegrafverket had 55,000 subscribers, most of them outside Stockholm. SAT had 25,000 subscribers in the capital. Private networks outside Stockholm were almost nonexistent at that point.
SAT had the biggest local network in Stockholm throughout this period, but Telegrafverket controlled the regional trunk lines. Discussions were held time and time again on interconnection, in other words, allowing one network’s subscribers to reach subscribers in the other network. Interconnection was even achieved during some periods, especially because of pressure from the Stockholm City Council as well as the government and Riksdag. In conjunction with this, the Stockholm market was divided up between the two telecom operators. They also discussed on a number of occasions whether Telegrafverket might purchase SAT. But this was long rejected by the Riksdag.
On June 5, 1918, after lively debate the Riksdag finally allowed Telegrafverket to purchase AB Stockholm Telefon, which SAT had been called since 1908. An important reason for the Riksdag’s decision was rising costs brought about by the world war, during which the government’s financial position deteriorated. The government and the Riksdag wanted to raise telephone tariffs generally in Sweden and in particular in Stockholm. Telegrafverket had been forced to keep prices lower in the capital than in the rest of Sweden because of competition.
After Telegrafverket bought AB Stockholm Telefon, the networks were quickly integrated, and telephone tariffs in Stockholm were raised to the same level as those in the rest of the country. Although no legal monopoly was established, the acquisition marked the end of more than 25 years of tough competition and the dawn of an era that would extend more than 60 years, characterized by a de facto state monopoly.

Telephony and the Swedish model
The change of the guard in telephony coincided in time with the emergence of a new Swedish social order: the Swedish model. The 1920s were marked by a double power shift among the Swedish elite. In the business world, an older generation of merchant capitalists was replaced by a new generation of industrial capitalists. In politics, the labor movement took power from the conservative civil service class to man the state bureaucracy.
The organizational philosophy of the Swedish model was borrowed from modern American big industry, where men such as Frederick Winslow Taylor and Henry Ford were preaching the gospel of professional management, economies of scale, and standardization. Added to these was a distinctive characteristic of Swedish social development for the previous 500 years, namely a relatively high degree of consensus.
This organizational philosophy would greatly impact the new Swedish telephone system. The main player was Televerket (the old Telegrafverket that had changed its name in 1953), managed by engineers and civil servants. It worked closely with LM Ericsson, a prominent Swedish industry based on innovation. With extensive political consensus, a professionally managed, standardized telephone system was created to make the most of economies of scale. This telephone regime was successful in building up and developing the telephone system in Sweden and laying the foundation for a major export industry.

Hi Eric, please pardon the late reply. Let me begin by stating that very few VDSL users experience a full 52 Mb/s due to the distance gradients involved, and no cable modem users receive data at 58 Mb/s. The best that I've seen reported in recent times for a cable modem user (bear me out Graciella) was something on the order of 6 to 8 Mb/s downstream under ideal conditions.

I'm not saying that it's impossible for the MSOs to do some tweaking and change their settings to get the results that you mentioned, but I doubt that they will, due to a number of other system constraints that they are forced to live with under the current DOCSIS regime. I therefore think that it would be more prudent not to mention those rates (for DOCSIS modems), at all, and for VDSL I would instead use the 12 and 25 Mb/s benchmarks for the majority of user experiences, with only the upper edge of the curve (those who almost live on central office property, or who have field nodes in their immediate reach... and of course, those tenants in MDUs who have a VDSL DSLAM in the basement) receiving a full 52. But even here I think that we are about to see some interesting tradeoffs, as the costs for Gb (and future 10Gb/s) Ethernet backbones, and user links, begin to nose down over time.

Your view of the modes that users have as options seem to be skewed to two distinct sets of applications. You have enumerated and compared the data-centric PC use to that of the TV and made different assumptions for each.

My view, in contrast, is that Internet-based (or IP protocol-based) video will, over time, supplant a goodly part of what we now know as video in the form of NTSC over RF, i.e., as it is currently being delivered over cable, and in those rare instances where it is being delivered over VDSL in the form of NTSC over MPEG. In the interim, I see NTSC over MPEG over Ethernet as just as viable a choice now as I do NTSC over MPEG over VDSL. If not immediately, then very soon.

And for these types of combined multimegabit data applications (combined multi-megabit data and video), the cable modem approach using the DOCSIS modem is no match, due to the windowing that takes place in the downstream. Let me clarify that somewhat:

Unless the MSOs with the assistance of Cable Labs bring their home-cluster size per node down to between 30 to 50 homes (AND increase their allotted spectrum for data purposes, at least in the downstream), there is little guarantee that users on those systems will ever be able to receive the IP based video and data services that I am suggesting, even at the line rates that you are suggesting.

And when we look at VDSL, what is it actually but a variant of (or, in actuality) Fiber to the Curb or Neighborhood? Most of the homes that were reachable by the central office have already been served or will be served by the less-expensive and lower-speed ADSL. It's ironic, isn't it?

VDSL platforms which use fiber in the backbone are the closest things that you can have to FTTH without actually being FTTH. Were it not for the last couple hundred or thousand feet of copper emanating from the field node to the home, terminating into a "modem," it would be very similar to some forms of FTTH. Imagine simply moving the side of the garage out into the brush by some distance.

Here, too, I should use some more caution than I have up until now, because the term "FTTH" can be parsed to mean a number of things: PON ala ITU, or GbE to the residence, or a form that simply mimics RF cable systems by modulating fiber with FM until it gets to the garage, where it is demod'ed into black coax, same as usual.

In the last of these cases of FTTH just mentioned above, FTTH is different than MSO black cable delivery only due to the following two exceptions: (i) it uses FM modulation over fiber instead of other forms of (mostly AM and vestigial sideband) modulation over coax; and, (ii) the amount of bandwidth allotted to data in the RF mimicker is usually higher, starting at 10 Mb/s Ethernet now - both ways - scalable up to 100 Mb/s (Fast Ethernet) and beyond, in the future. Some already offer 100 Mb/s now.

One point that I'd like to repeat here is that there is more than one type of FTTH scheme being deployed today. In time, most of them will be more economical and bountiful, on a cost per bit basis, than what we have in place now. Comments, corrections, always welcome.
