Ayn Rand's essay contains a fundamental technical flaw when she says that two broadcasters cannot share the same frequency.  Even Edison, Telsa, and Marconi knew they could. 

In theory, you could have AM and FM at the same frequency.

Not all wavelengths are equally desirable. Shorter wavelengths can carry more information (at least as we understand now).  So, shorter wavelengths are more desirable, perhaps, or perhaps not.  Is the government or the market to be the arbiter of how to evaluate the "ether"?

Does it make sense to define the "airwaves" (such a primitive term) by their wavelengths? 

"E equals h bar nu" shows that a thrown baseball has a wavelength.  Should baseball pitches be regulated by the FCC and their "property status" be auctioned off?

I thought that you were going to try to advocate that the inventor of 'the wave' should be able to charge all participants a royalty.

True, if a little harsh. To be precise she would have had to say two broadcasters cannot share the same frequency at the same time in the same place using the same modulation and same polarity (you can have dual use of the same frequency or very near the same frequency if the transmitters use different (horizontal and vertical) polarities, depending on the quality of the receiving equipment).

You could go one further if you wanted to be especially churlish and say that John Galt's speech could never have happened. As I recall, he manages to "jam" every frequency in the country, or presumably at least every broadcasting frequency. Technically not impossible I guess, but imagine the transmitter power you would need to do it - you would need to be transmitting across a whole range of frequencies everywhere at the same time.  That's an awful lot of transmitters at the top of an awful lot of transmission towers. Unless of course he had discovered some new form of energy which somehow did the job for him.

From memory there's also a reference in Atlas Shrugged - can't remember if it relates to John Galt's speech or somewhere else in the book - to "a frequency that had never been discovered before", which doesn't really make sense since if you've discovered one frequency you've discovered them all really, since the spectrum is just a continuum. It's rather like saying you've "discovered" a certain number.
Not all wavelengths are equally desirable. Shorter wavelengths can carry more information (at least as we understand now).  So, shorter wavelengths are more desirable, perhaps, or perhaps not.  Is the government or the market to be the arbiter of how to evaluate the "ether"?

Ideally, the market should be the arbiter, but this is rarely the case. In New Zealand and Australia the auction process often does not specify the technology, so competing technologies can in theory compete for the same frequency range. But the technologies have often developed for historical reasons out of Government decrees about the usage of certain ranges for a certain purposes. And in any case technology develops globally, so the policies of the FCC, not the NZ or Australian authorities, are likely to dictate the technology.  Most frequency licences, in NZ, Australia, the US and everywhere are not allocated by auction anyway and are not tradable.
Does it make sense to define the "airwaves" (such a primitive term) by their wavelengths?
Yes. The "fences" for radio frequency property rights must be clearly defined in a number of dimensions, including at the very least: frequency, location, power, polarisation, and an exclusivity/time dimension.
Should baseball pitches be regulated by the FCC and their "property status" be auctioned off?

No. I can't imagine they emit at enough power to interfere with anything, so there are no property right issues involved.

I do not see the relevance in the science fiction aspects of Atlas.  Rand (as opposed, say to Asimov or Heinlein) was not very technical and John Galt's invention of 1957 was recycled from an older idea circa 1937, if I remember The Early Ayn Rand correctly.  So, no, I choose not to be churlish.

You contradict yourself and you underscore the point I was making when I asked how to define the "fences" (thanks for the term) of the "airwaves."
MEM:  Does it make sense to define the "airwaves" (such a primitive term) by their wavelengths?
1.  JS: Yes. The "fences" for radio frequency property rights must be clearly defined in a number of dimensions, including at the very least: frequency, location, power, polarisation, and an exclusivity/time dimension.
2.  but above that JS: "To be precise she would have had to say two broadcasters cannot share the same frequency at the same time in the same place using the same modulation and same polarity (you can have dual use of the same frequency or very near the same frequency if the transmitters use different (horizontal and vertical) polarities, depending on the quality of the receiving equipment)."
You can have "dual use" of a building -- parking garage by day, skateboard arena by night.  Someone still owns it.  The definition of land-based property rights seems pretty well established.  We have no such definitions for "airwaves."  They are not part of the (ahem) "collective subconscious" (sorry) in that I do not intuitively know what you mean by what you say.  When I say, "Get off my land!" You do not have to wonder if it is the same land by day as it is by night, turned to mud by rain or covered by snow, etc.  With the "airwaves" the "fences" are not well-defined because we have not lived with the airwaves long enough.

Letting the government define them ex nihilo and a priori was wrong. I prefer the chaos of anarchy.  Let the strong rule the weak until the weak get clever enough to sneak around them and in a little while, the markets would decide where the profits are and that would define "property rights of the airwaves." 

I will grant that the USA way of auctioning them off the last time around was much better than the OZ and NZ methods.  The USA used a Nash Optimization. (Google FCC auction John Nash..)  The OZ/NZ auctions resulted in bizarre outcomes and a sub-optimal realization of income.  On the other hand, in the USA, the frequencies went to people who wanted them at the highest price the market would bear.

This does reflect another limitation on Ayn Rand's theory (or lack of one).  Broadcasting has power limitations based on wavelength and modulation.  Australians can misallocate 50 MW 1100 KHz AM and it has no effect on me in the American Midwest. 

Now, we have digital radio via satellite. With three birds in geosynchronous orbit -- a crowded piece of real estate with no government control, just some weak treaties -- you can broadcast the same program to everyone on Earth at the same time.  ("This is John Galt speaking...")  That was never contemplated in the days of Ayn Rand -- at least not by Ayn Rand.  Too bad she read Mickey Spillane instead of Arthur C. Clarke.

I disagree with this in so many ways.

Firstly, there's no contradiction in the definition of the fences. Look again at the full list of dimensions I provided for defining the fences: frequency, location, power, polarisation, and an exclusivity/time dimension (you could add to that unwanted emission limts, but the list is long enough for now).

What I'm saying is that you can define two property rights for the same frequency if you use different points in the polarity dimension, if the equipment is up to it. Likewise you can have dual use in the polarity dimension if you have different points in the frequency dimension (e.g. two transmitters with horizontal polarity will not interfere with each other if they operate with a wide enough gap between two separate frequencies).

Your example with dual use of the building fits my definition of property right fences, since you are just talking about different points in the exclusivity/time dimension (which I included in my list). Radio frequency licences can (and do) specify transmission during certain hours (e.g. some AM frequency licensees are required to reduce their transmitting power at night-time, or even shut down altogether because the signal would carry too far at night and would interfere with someone else). Or licences can specify non-exclusive use at a single point in time (e.g. shared bands for trucking companies) or exclusive use at all times.

Time is just another dimension in which the property right is defined. No big deal there.

Secondly, it is incorrect to say we have no definitions of property rights for radio waves. Governments have been defining the fences for property rights for decades. That's what they do when they define and protect a licence to transmit. 

The fences work fine, its the method of allocating those rights and the legal rules around what you can do with them that have been the problem. Governments have been moving to address those problems by making the rights long-term, using auctions to allocate the rights, and and allowing them to be tradable, mortgagable, varied (i.e. you can adjust the fences if there's spare room around you), and so on.

Thirdly, you are espousing a common myth about the early NZ auctions. There is a common misconception that those auctions were a failure because some licences (as in one or two) went very cheap due to the lack of depth in the bidding market and the second-price bid rule. But the "optimisation" of income is not a valid objective in the sale of spectrum rights. The Government is effectively a monopoly seller of the rights, so if profit maximisation were the objective the government should just rip off the market through a process of mis-information, changing the rules, etc.

No, the object of the auctions is to get the property rights out of government hands and into private hands in a clear and transparent way. The income earned is a mere by-product (and one which the government has no moral right to in the first place).  What I would call a failure is the UK govt's sale of mobile telephone bands, where they fleeced £22 billion out of the telecoms industry, and handicapped the industry from the outset.

Fourthly, I don't agree that anarchy would be the way to go. What the Government should have done is simply draw up property rights that when people signed up for use of the spectrum, along with some use-it-or-lose-it provisions, and have done with it. Drawing up the fences isn't the problem in that process, its dealing with the thorny issues around the initial allocation that are complex. But those same issues apply with land, so you may as well focus on the complexities of the homesteading of land, rather than try to argue that there is something inherently difficult about radio spectrum that makes property rights impossible to define.

Tim, I am sorry that you see disagreements.  I see a lot of common ground -- or shared frequency, or something...

TS: Firstly, there's no contradiction in the definition of the fences. Look again at the full list of dimensions I provided for defining the fences: frequency, location, power, polarisation, and an exclusivity/time dimension (you could add to that unwanted emission limts, but the list is long enough for now).
Just so!  Therefore, allocating the frequency only as the essential distinguishing characteristic of the phenomenon is wrong.  The governments could just as well have auctioned off frequency-polarisation.  I mentioned Edison at the top.  As a telegrapher, he worked out a mode of quadriplexing signals on the same wire.  Now, we all agree on the rights regarding wires, but you see the problem with these rights in the "ether."  I could take any frequency I want, say 1100 KHz -- a popular choice here in the States for AM -- and I can send all kinds of stuff at that frequency without being detected in any way.  We cannot pasteur two herds of sheep in the same lot at the same time.  Our ideas of "property" are land-based, but radio is different in ways that we do not yet appreciate. 

I agree with just about everything else.  I agree that at least having the government get out of the radio wavelength business is a good idea.  I only believe based on facts and reasons that they never should have been involved in the first place. 

Again, here in the States, as you note, certain stations have to power down at night so as not to interfere with other stations's so-called "rights" (grants from the state, not natural rights) to broadcast.  I believe that without government interference in the marketplace, technical solutions would have allowed just that: two stations on the same frequency at the same time with no interference and everyone's listeners paying for the service.

(And you know, it is not true that we all understand the rights regarding wires.  If you stop and think about it, you realize that telegraph wires could interfere with each other by induction.  A court case about that in 1850 might have laid some precedents for radio, but it never happened.)

Well, the trouble is that the government, or at least the courts, always be charged with enforcing property rights of some sort.

As I see it the system should work like this. I am using a frequency at 1100 kHz. You come along and try and register with the government a right for the same (or very near) frequency using some slightly different technical specifications. The government investigates whether your frequency will interfere with mine (at your expense) and either registers or declines the right, or perhaps allows a temporary testing period.

For non-broadcasting frequency ranges, I understand that's basically the way it has worked for a long time.

Your main complaint seems to be that the government has been overly conservative in registering new rights. Maybe that's true, maybe not. But would you agree that would be a problem of process rather than one of principle?
