BLP vs. Photons

This morning the FCC announced approval of Internet access over power lines, BPL. Any added competition bodes well. It sounds a little like a rich man trying to get into heaven through the eye of a needle, pardon the metaphor. There are technical problems. Ham operators fear radio interference. However, the simplicity of the plug in to any outlet with just the one connection seems appealing. The added competition may force open the road blocks holding back fiber optics. Michael J. Copps, one of the commissioners commented that we, the US are now 11th in broader band access. I cannot bring myself to calling it broadband because it is not. Digital over powerlines still deals with electrons with radio frequency E-M (electro-magnetic emmissions) as the undesirable byproduct when E-M can do the job better.

On the course of true broadband deployment, SBC Communications just announced that they would light up more fiber optic cable using technologies from JDS Uniphase and Avanex. (E-M in the light frequency range=photons of light) These two, bubble time companies have floundered in the depression as incumbent phone companies refused to keep pace with the digital economy. Theirs are the quantum technologies that carry bandwidth for information beyond the gigabyte range.

While I was recently in the South Pacific, I interviewed a man who spoke at a regional communications seminar. Hendricks I recall, I have no Idea of his credentials but judging a man by his laptop, he was upper management. In our discussion of broadband deployment and the interface of electronics with photonics, he said, “you can’t do anything with a photon. It is either there or it is not.” Now I am not a space age physicist, but a photon can be oriented 360° (polarized) and formed in an almost limitless number of wavelengths (colors). The point is that herein lays the greatest obstruction to Moor’s Law in evolving bandwidth --- the comprehension of management and analog minded engineers. All of the digital, spread spectrum and multiplexing options of radio and microwave are available in fiber! It warms the sole to see two of the photon folks, as mentioned above, get the nod.

Inflation

Many retail investors buy individual stocks with growing confidence in a narket that has a long run. Many fail to appreciate the way the market reflects inflation. Company revenue consists of inflated number,s as does cost and profit, thus the market reflects true inflation which must now be near 100%.

Election 2024

The November 2024 election presents a significant challenge, transcending the traditional Democrat versus Republican divide. This election will determine the future of the American Republic, Western civilization, and potentially the survival of the human species. Plato suggested that democracies tend to devolve into oligarchies, and we are witnessing that transformation before our eyes. Three major trends in the U.S. threaten to replace our Constitution and representative government with a totalitarian, internationalist, socialistic oligarchy. First, seventy years of Soviet subversion, the Vietnam War, and generations of youth who were taught to reject American institutions have undermined U.S. leadership. Now, Chinese espionage, bribery, and infiltration further contribute to the erosion of America’s traditions of citizenship, enterprise, and prosperity. Second, NGOs in Washington, an entrenched bureaucracy, and organizations like the Trilateral Commission prioritize internation...
