      The question isn't really whether whoever gets the spectrum is evil, but rather how well their interests align with those of the user base (you and me). Google is in a rather special situation because 1) they are not a network provider (like Verizon and Comcast, whose goal is maximize revenue from - yet minimize investment in - infrastructure), yet 2) google is not a normal content provider, either - mainly they provide links to other content, since their main product is advertising. What this means is that google has a unique business interest in encouraging new services - especially data services - that (i.e.) Verizon does not.

      Here's the best paragraph from the article:

      Will Google buy the spectrum? They certainly have enough spare cash to do so. If they do, it seems unlikely that they would operate the network themselves since it's a long way away from their core business. Instead, they would be likely to sublicense it to other players with the four conditions they originally hoped the FCC would impose [ensuring open services and open networks].
      If this were to happen, I think it would be a good example of the free market working as intended. US cellphone companies are destroying much of the value of the spectrum they control in order to serve their own narrow interests (e.g. charging hundreds of dollars per megabyte for SMS messages). Since google's business model provides more value to more people, google has more cash on hand to win the bandwidth auction. With any luck this could all work out just right.

      Yes.

      If it's the former, how does that work?

      Like I said: Look up "steerable null".

      You compute the strengths and phases for each of the N antennas to create a pattern that has a null at the angles toward stations 2 through N but not on station one. You modulate that with the information you want to send to station 1.

      You also compute another set of strengths and phases to put nulls on stations 1 and 3 through N but not on station 2 and modulate that with the information you want to send to station 2.

      Ditto for stations 3 through N.

      Then for each antenna you sum the N modulated streams, convert them D-to-A, and THAT's what you send up the feed line. (Actually you send a lower-frequency IF: N pairs of signals, in quadrature, one pair for each antenna. Up by the antenna you up-convert it using a common local oscillator for all the antennas so it stays coherent.)

      All this pattern forming is done in a DSP with an NxN matrix multiplication in complex numbers. It's a drop in the bucket compared to the inverse-FFT computation it's doing to construct the modulation.

      In the receive direction you down-convert with a common local oscillator to get N sets of quadrature signal pairs, digitize them, and multiply by the inverse matrix. This resolves the signals from the N antennas into N signals equivalent to N separate complete sets of antennas with the same N "nulls on all but MY guy" patterns as with the transmitters.

      Of course just as the local oscilators had to be common across all the component antennas' transmitters and receivers, the D-to-A converters have to share a clocking reference, and the A-to-D converters ditto.

      On top of all that the individual antennas of the array have a pattern of their own which defines the sector - typically a 120-degree (plus a tad) fan, breaking the coverage area up into three chunks, each with its own set of N antennas. The total pattern is the product of this fan pattern with the patterns computed for the steerable-nulls.

      Nice thing about it is that you can command one of the station transmitter to send you a test pattern in one of the (many) frequency slots of the orthogonal-frequency-division-modulation - one which you reserved for signaling - while you're commanding the rest of 'em to shut up. The signal strengths and phases you get from doing this for each of the remote stations lets you construct your pattern matrices.

      You actually end up constructing patterns that turn multipath to your advantage, so the direct signal and the reflections sum up to a better-than-single-path signal on the target station while the multiple paths to the other stations sum up to a good null.

Let me describe the simplest example I can think of so you can point out to me where I'm not getting it. Say you want to transmit the same simple carrier wave to two points at the same time. You are using two dipoles oriented vertically to transmit, one is directly north of the other, one wavelength away (just using one wavelength to make the math simple - if a different number is needed, let me know).

For the southeast station to receive a coherent signal, the opposite is true. So if you just add the signals together, you're sending out two sine waves simultaneously out of both antennas. Two sine waves of the same frequency added together will always add to one single sine wave (which is how you get 208V from two 120V power phases), and if the two components are 105 degrees apart (360-255=105), that single sine wave will have 159% of the strength of one of the components (whereas if the signal power was not split between the antennas this would be 200%). Since it leaves both antennas at the same time, and they are one wavelength apart, the radiation pattern will have a 3db gain (not relative to the 159%) at the north, south, east, and west points with nulls in between each point.

      So far so good. Here comes the oopsie:

      For the northeast station to receive a coherent signal, the signal needs to leave the southern antenna .707 wavelengths (or sqrt(2)/2*360 = 255 degrees) ahead of the northern antenna. For the southeast station to receive a coherent signal, the opposite is true.

      Here's where you're starting to go wrong. You don't need the northeast station to hear the strongest possible signal (be in the middle of the antenna pattern's major "loop".) What you need is for it to NOT hear the signal intended for the SOUTHEAST station (be bang in the middle of one of the "null"s in the pattern intended for that station.) Loops are broad. Nulls are sharp. You want the best ratio of "my signal vs. other guy's signal", which is achieved by minimizing the other guy's signal rather than maximizing your own.

      So if you just add the signals together, you're sending out two sine waves simultaneously out of both antennas. Two sine waves of the same frequency added together will always add to one single sine wave (which is how you get 208V from two 120V power phases),

      Yes.

      But that will also be true if they're NOT in phase. Adding two sine waves of divergent amplitude and phase still gives you a sine wave of the same frequency. But to get the strength and phase you need to take the vector sum. If the vector sum from all the antennas cancels out you STILL get a sine wave of the correct frequency - but one with zero amplitude.

      In your two antenna case they have to be the same strength and the phase difference plus the propagation time difference total to 180 degrees to cancel completely.

      and if the two components are 105 degrees apart (360-255=105), that single sine wave will have 159% of the strength of one of the components (whereas if the signal power was not split between the antennas this would be 200%).

What am I missing?

      That's fine as far as it goes. Your in-phase signal goes N, S, E, and W and has four nulls in between. But this has nothing to do with the remote stations in the NE and SE directions.

      You're not analyzing what happens when you shift the phase of the signals going to the two antennas.

      The South antenna's signal gets to the SE receiver 0.707 of a cycle earlier than that from the north antenna. To put a null on the SE receiver you need that to be 0.5. So you delay the signal to the S antenna by 0.207 cycle.

      As viewed by the NE receiver the signal from the South antenna is delayed by 0.707 cycle by the propagation delay plus 0.207 cycle by the deliberate phase difference at the South antenna, for a total delay of 0.914 cycle. They're almost in phase, and add up really well. So the SE station is at a null, while the NE station is ALMOST at the middle of a loop. The NE station hears this signal just fine, while the SE station doesn't hear it at all.

      Similarly if you delay the NE antenna by 0.207 cycle the NE station will not hear THIS signal at all and the SE station will hear it just fine.

      Now modulate the two signals separately, one with the stuff you want to send to the NE station, one with stuff for the SE. Add 'em up and put 'em into the antennas. It's a linear process so the sum of the comp

      I think you've hit on an interesting issue in all of this, and I wonder why you didn't put more emphasis on it. The wireless spectrum is a *public* resource. Somehow this whole debate about the 700Mhz spectrum always gets framed in such a way as to imply that some huge company necessarily must own it. However, it's technically public and only gets licensed to some company for commercial use.

      It really must not be forgotten. AT&T has no legal right to own the 700Mhz spectrum. It would be much more true to say that the people of the United States own that spectrum and always will. The question in front of us (and in front of *our* lawmakers (those lawmakers work for us!)) is how we wish to use that spectrum. Even if we license it to some particular business or group for the development of commerce or infrastructure, we have every right to put limits on how it can be developed and used.

      For some reason, we've been tricked into not thinking of things that way. Radio waves travel through the air over everyone's property and through our bodies all the time. It's inherently public, like light or air. A responsible government cannot auction off those sorts of resources without any restriction on how they can be controlled or used. Moreover, what we're talking about here is the development of a national telecommunications infrastructure. We wouldn't let a single company own all plumbing so that all pipes, faucets, sinks, and toilets had to be purchased from that company. We wouldn't allow a single company to own all of our roads and highways such that they could deny passage to any driver or any car brand. We shouldn't allow a single company to control our communications over the entire country.

      We are talking about making use of public resources in order to create national infrastructure. I have no objection to involving private companies in the development of that infrastructure, but the end result needs to be regulated in favor of the public good.

      And no, I'm not a communist or socialist. I don't believe the federal government should be involved in very much. If there's one thing the federal government should do, it's maintain a standing army. If there are two things it should do, it's maintain an army and regulate the maintenance of national infrastructure.

      People are always quick to demonize the corporation without giving any credit to the benefits allowed by such legal organizations of resources and people. While it is true that corporations, like people, sometimes behave badly it is also true to say that the modern lifestyle, which is based upon a foundation of incredible complexity, would not be possible without the organizational rigor and specialized expertise that only becomes possible when some formal notion of an organized group of private individuals, acting in concert to achieve a set of goals, is recognized by law (i.e. the corporation). How does this relate to business needs trumping the consumer interest you ask? Well, consider the following.

      It costs money (i.e. resources) to run the government, enforce the laws, and generally to perpetuate the lawful and civilized society that we all enjoy. Now, if the government can offset some of that cost by leasing a public resource, be it public land or in this case the EM spectrum, then it is generally obligated to do so, provided that certain rules of conduct are followed, because if the public resource were not leased then the government would have to make up the extra revenue somehow and that generally means more and higher taxes. You might *really* want to use that 700 MHz band, being a radio enthusiast perhaps, and are willing to pay higher taxes in order to have that resource stay completely in the public domain, but most of the rest of us, on the other hand, are not equipped to make use of the spectrum and do not want to use it for long range radio broadcasts and communications. The rest of us would prefer to lease our interest in the spectrum in exchange for something else (lower taxes hopefully) instead of trying to use it ourselves.

      It is therefore in the public interest to conditionally lease the spectrum to someone who can offer us the services that we want at a reasonable price while allowing those who do not want to use the spectrum a lower rate of taxation (at least in theory) in exchange for leasing their interest in the spectrum. This way the people that pay are the people who use the most which I think we can all agree is eminently fair and in the public interest.

      Helping New Orleans rebuild and improving the storm protection and coastal restoration is the least the rest of the country could do. The amount of resources it would take to start making some significant progress is a small fraction of what our government has available to it, and it's really a shame that our priorities won't let that happen.

I don't know if you're imagining New Orleans as a bunch of lazy people sitting on the side of the road waiting for the government to help, but I can ensure you that that is not the case for the majority of the city.

But as is always the case, there's a lot of circumstances beyond just the textbook economics, and things pretty much never move quickly or smoothly. I think that New Orleans as a whole can and will continue rebuilding, even if the federal government never gives out another dime. It'll just take much much longer, and many hardworking but unfortunate people won't be able to be a part of it for various reasons.

When people dismiss the whole thing with things like "they knew they were building a city in an unsafe place", or "if they want better levees they should build them themselves", it's pretty upsetting. The federal government committed to a flood protection city that would've kept New Orleans safe from Katrina. They told us that the system was sound. I'm not naive enough to take everything a politician says at face value, but when you're dealing with something like flood protection, you expect the Corps of Engineers to have their act together.

      The worst part is, the levees and flood walls around New Orleans are just a small portion of the huge amount of infrastructure nationwide that the federal government is responsible for. Like that highway bridge collapse a few months back, their is a ton of infrastructure of all types that has been under-maintained for decades, and it looks like it's going to start catching up to us.

    I've re-read it, still not getting it. The "invisible hand" of economic pressure can control commerce and have it be a free market and a good thing, but what does it look like when the "invisible hand" of economic pressure controls the federal government?

    Individuals in the government should not be making decisions based on their own personal economic gain. When they do, I'd tend to call that some kind of "bribery" or "corruption", even if it's not explicitly structured with one guy handing money to another.

    In my opinion, the federal government should limit itself to a narrow scope and content itself with limited powers, but should always use those powers judiciously for the sake of the public good. What room is there in that for "commerce"?

    The only way for the "free market" to be more "free" than that would be to disband the government entirely and have a general anarchy loosely controlled by whatever commerce can survive the anarchy. I guess there are probably people out there who think that system would be good, but they're madmen. It would greatly harm "the market" anyhow.

    Prohibition leading to increased alcohol consumption, formation of gangs, gang wars, shooting wars between gangs and law enforcement, poisonous booze, etc. Similarly with the "drug war".

    Gun restrictions leading to increased crime - including increased shootings.

    Anti-poverty programs leading to an increasing fraction of the population permanently supported by such charity.

    Price controls leading to alternation of shortages (i.e. gas lines) and further price increases.

    Federal aid to and meddling with school systems leading to drastic reduction of the quality of public education - until some public schools are literally graduating more illiterates than readers.

    I could go on.

    Individuals in the government should not be making decisions based on their own personal economic gain.

    The individuals I'm talking about are the citizens. The invisible hand works in more ways than via money.

    Meanwhile, the government deals in the economy of negative values (such as the use of force, theft, imprisonment, and killing). Some of the same "invisible hand" analysis can be applied to such values and the "market reaction" of the people these are applied to. But their reaction to the negative sign on the "value" causes higher-order effects to be stronger than first-order, leading to explosions of unintended consequences. So the design and application of law is not straightforward.

    One of the differences between the capital-letter "Progressive" and "(classic, non-Neo) Conservative" sides of the culture war is that the Progressive side acts as if the first-order ("intended") consequences of the laws are their only effect - leading to an explosion of trying harder and making it still worse when the effect is the opposite of what is expected. Classic Conservatives take into account the second-order effects - which makes them look insane to those who don't understand what they're doing (and won't listen to, or won't believe, their explanations, or will reject them because they're not "nice".)

    It's not immediately obvious, for instance, that fewer guns means more crime or that selfish motives can lead to good long-term effects for others and altruistic motives to bad ones.

    Ok, that's a big long explanation of why you're conservative, which is fine. But my question is how are you going to have "commerce" run the government as a good thing? Even if you have conservatives running the government, using careful planning and looking towards secondary and tertiary consequences, they still shouldn't be choosing laws based on personal economic gain, should they? Shouldn't they be making laws for the good of the country, and not based on what makes them money?

    Maybe I'm alone here, but I think universities such as Harvard (and others) should team up and buy the 700MHz spectrum.

  59. Let's try that again. by Ungrounded+Lightning · · Score: 1

    On re-reading I see what you were getting at. Let's try that again:

    Two sine waves of the same frequency added together will always add to one single sine wave (which is how you get 208V from two 120V power phases), and if the two components are 105 degrees apart (360-255=105), that single sine wave will have 159% of the strength of one of the components (whereas if the signal power was not split between the antennas this would be 200%). Since it leaves both antennas at the same time, and they are one wavelength apart, the radiation pattern will have a 3db gain (not relative to the 159%) at the north, south, east, and west points with nulls in between each point. What am I missing?

    You're missing that the two sine waves are equal strength and phase (in your simplified, symmetric, case) only when both stations are supposed to hear an equal amount of signal and hear it with the same phase (as measured at the transmitting location). If the modulation later calls for the NE station to hear the signal 180 degrees out of phase (compared to the previous case) its component at the antennas will be phase shifted. The signals at the two antennas will no longer be in-phase and equal.

    In your first case the N antenna gets one sine wave at 0 degrees and another at -0.207 * 360 = -74.52. In the second case it gets one sine wave at 0 degrees and another at -0.707 * 360 = -105.48. Meanwhile the S antenna had 0 & -74.5 in the first case and -180 & -74.52 in the second.

    case 1:
      - N antenna: Phase -37.26 degrees. Amplitude 1+cos 74.52 degrees.
      - S antenna: Phase -37.26 degrees. Amplitude 1+cos 74.52 degrees.

    case 2:
      - N antenna: Phase -52.74 degrees. Amplitude 1+cos 105.48 degrees.
      - S antenna: Phase -127.26 degrees. Amplitude 1+cos 105.48 degrees.

    See how that works?

      But you repeatedly said that I could send signals simultaneously and independantly to multiple transmitters. If I cannot choose those signals to be identical or different on my whim, then they aren't really independant, are they? Since you are claiming a multiplication of total bitrate, you will need to make this simple test case work in order to prove your point to me.

      (Also, I only care about the signal measured at each receiving location. Do whatever you want at the transmitter as long as you don't boost ERP/EIRP over a traditional config, which would presumably be tweaked to run just below the legal limits anyway. Sorry if that was unclear.)

      But you repeatedly said that I could send signals simultaneously and independantly to multiple [remote stations]. If I cannot choose those signals to be identical or different on my whim, then they aren't really independant, are they?

      I just showed you a case where the two stations get independent signals.

      I happened to pick two examples where I ran the whole math:
        - Send a sine wave to station SE but not NE and the same sine wave to station NE but not SW.
        - Send a sine wave to station SE but not NE and the negation of that sine wave to station NE but not SW.
      You can generalize that to sending any signal you want, separately to each remote station.

      The general form (for these particular angles) is:

        Antenna N signal = real(carrier * ((mod(NE) * coef(N,NE)) + (Mod(SE) * coef(N,SE)))
        Antenna S signal = real(carrier * ((mod(NE) * coef(S,NE)) + (mod(SE) * coef(S,SE)))

      Arithmetic is complex numbers. Carrier is e^(i*omega*t), i.e. a cosine wave and an imaginary sine wave (i.e. the cosine wave delayed by a quarter cycle is the imaginary part of the complex number).

      For this two-antenna, two-station case: one of the coef(ficients) is 1 and the other just a phase rotation: (cos(d) + i*sin(d)), where d-pi radians is the delay you would need to make the signals from the two antennas match exactly at the station you're trying NOT to send this modulation to. Adding pi inverts the signal from that antenna and causes it to cancel exactly at the "don't hear me" station. This second coefficient is a complex number which also has magnitude one. (For more than two antennas and two remote stations the coefficients will have varying magnitudes as well as phase angles.)

      I can't make the math work for simultaneous transmission. Perhaps we could work backwards from the receivers for a few data points and look at the signals that must have been sent from the transmitters?

      Let's go back to receiving the same phase of the same sine wave at both the NE and SE receivers, with a 3dB gain, from N and S transmitters 1 wavelength apart. To keep the math easy I'll pick the data points so that one transmitter is received exactly one point behind the other - sqrt(2)/2*360=255 degrees apart (105, 0, 255, and 149 degrees). Assuming the maximum power at N and S ranges from -1 to 1, the received signal for points 0, 1, 2, and 3 at both NE and SE must be 1.928, 0, -1.928, and 1.027. That means that:

      N[0]+S[1]=SE[1] (0)
      N[2]+S[1]=NE[2] (-1.928)
      N[2]=N[0]-1.928 (remember, maximum power is -1 to 1, therefore the swing from N[0] to N[2] must use nearly all of this range, N[0] must be between .928 and 1, N[2] must be between -1 and -.928)
      N[2]+S[3]=1.027 (but there is no number between -1 and -.928 that can be added to another number between -1 and 1 such that the sum is 1.027)
