  1. Re:Cell phones won't work, and front-end overloadi on Cellphone Use On Planes Coming Soon? · · Score: 1

    Did you miss the whole 9/11 thing with people calling the ground reporting they were being hijacked? Obviously phones are more than capable of holding extended conversations at altitude.

    The experiments I cited, and later reports proved that the "cell phone" calls made by the hijack victims were actually placed by the plane's airphones. Airphones are satellite phones on many plane flights that require the use of a credit card to activate. Do a Google search, and you will even find a link from QUALCOMM, CINGULAR, and VERIZON all stating that the reported cell phone calls did not take place via cell phone.

    Read the physics experiment article that I posted, and try a google search for "9/11 cell phone". Or find a friend with a pilot's license and try it yourself -- above 2,000, even at low-speed (2,500ft @ 65mph airspeed in a Cessna 150 is how I tried it), you will be hard-pressed to get a cell tower, and when you do you will have it for at most a few seconds. The reason for this is multi-fold: 1) cell tower antennas have horizontal, as opposed to vertical, polarization. This means that their signal spreads closer to the ground, and the radiation lobe is very small in the up-and-down direction. The reason? A cell tower would just waste power by broadcasting up in the air when there will be at most two people up there using that particular tower for 15 seconds. It makes a lot more sense to broadcast with a pattern that hugs the ground, where most of your customers are, especially when the cell company must pay the FCC by the watt for their tower. 2) at 30,000 feet, you are going to be a minimum of *five miles* from a tower, and you will not have the benefits of ground-wave propagation to help your tiny signal reach the tower. Coupled with (1), you simply won't get a signal (and you don't. Discreetly try it if you don't believe me [legal disclaimer: I won't be held liable for anything that happens should you actually try it ;-)]).

    Do a Google search, and you will even find a link from QUALCOMM, CINGULAR, VERIZON, and NOKIA all stating that the reported cell phone calls did not take place via cell phone. Nokia is even working on a wireless carrier system specifically for flights, which will allow the use of a cell phone in-flight, but using the AirPhone system.

    This stated, cell phones were used on the Pennsylvania flight, but only after the plane was well below 8,000 feet of altitude (one of my posts a few months ago on this topic had a link to a nice graph from a conference paper showing the altitude was about 4,000 feet, and that the terrain at the crash site was ~2,000 feet, lending more weight to the polarization/propagation arguments above). A normal commercial flight would only be at this low altitude for a few minutes during landing pattern, and about 2-3 minutes during takeoff (or slightly longer if, y'know, the plane was hijacked and the hijackers were trying to evade radar, or were intending to crash the plane, or something).

    As for interference rejection, yes shielding helps. But you cannot shield your antenna, and it is always going to be a conductive source for interference to enter your receiver. I have a very nicely shielded ham radio that still experiences front-end overloading from nearby radio sources, like my cell phone, other ham radios, etc. I cannot vouch for its shielding when compared to your car stereo's, nor to a plane's ATC comm system, but I'd like to think that it's pretty good. Buzzing still happens when I get a phone call, even on a non-harmonic signal.

    Just my $.02,

  2. Cell phones won't work, and front-end overloading on Cellphone Use On Planes Coming Soon? · · Score: 1

    Why is everyone making such a big deal about this? It's pretty well-established that cell phones will not work on flights once the flight goes above about 5,000 feet. My own experiments showed my cell phone stopped working about 2,000 feet up. My roommate a few months ago was a private pilot, and we lived in/flew over San Diego where there's a cell tower for every 50 sq. feet of ground cover. Other projects have yielded similar results to my own, and are far more scientific to boot. Couple this evidence with the fact that any lengthy flight is going to fly at well over 30,000 feet over areas with no cell phone towers.

    All that allowing cell phones will do in the US is make it so that a hundred or so people will have phones on during the whole flight, and those phones will switch to their highest power mode trying to find a tower. The pilot will hear this buzzing in his headset because his receiver's front end will overload. Try this: drive down the interstate, put your cell phone in your center console, turn your radio on and turn the speakers up. You hear that electronic humming that pops up every once in a while? That's your phone establishing a connection with a new tower. It is using the highest transmit setting at first, overloading the receive sensitivity of your car's stereo and causing a blaring sound through your speakers (actually it is inducing signal in your receiver, and this experiment will probably work in your stereo even when you play CDs/Tapes). Imagine a pilot trying to listen to a tower and instead hearing this cell phone garbage. It would not make for a very safe flight. What's really interesting? Modern radios are more susceptible to this behavior than older, tube-driven radios/amplifiers!

    Unless cell phones become far more powerful, and aircraft switch *back* to vacuum-tube radio receivers, there will be 1) no point to allowing cell phones on flights, and 2) it will actually make flights far more dangerous by effectively DoS'ing your pilot's communications.

  4. Re:Your info is outdated on NASA Announces 120 Small Research Projects · · Score: 1

    When I reviewed (~2 years ago) it was for the MDA (they weren't my employer, just the sponsors of the SBIR and needed my organization's mindshare to review stuff). We were told specifically not to judge the qualification of staff even though it was an evaluation criteria because the staff proposed is non-binding. That is, the company's inclusion of particular people's CVs does not mean that those people have any obligation to actually take part in the actual work. By SBIR standards, this is (or at least, was) okay, which strikes me as wrong. Potential commercialization is rather a moot point as well, and we were told to chiefly ignore it by the sponsors. The idea for this part is that a small business that is just starting out will not have a clear commercialization plan lain out yet. So long as they acknowledged that they would need help making business/government customer contacts, they were golden.

    SBIR data rights have indeed changed somewhat as I am just finding out. This case is particularly interesting. Still, five years? That's an awfully long time to wait for the data rights. Not nearly as bad as a 20 year patent, but still pretty bad for research that .GOV paid for...

    It is a delicate balance, I realize. On the one hand you want to encourage small businesses to get into this thing and thrive and get the government's work done, but on the other hand you don't want to get screwed if the small business decides to take the money and run. All too often I saw just that, though: the abusive side to the contracts...companies with a hundred phase 1 and a dozen or so phase 2 awards under their belt, but with no phase 3s.

  5. Re:Then write your congresscritter! on NASA Announces 120 Small Research Projects · · Score: 1

    I'd like to reply to myself with an excerpt from the SBIR award contract, just to highlight one of the other big problems: SBIR data rights.

    " (1) Each agency must refrain from disclosing SBIR technical data to outside the Government (except reviewers) and especially to competitors of the SBC, or from using the information to produce future technical procurement specifications that could harm the SBC that discovered and developed the innovation."

    So, essentially if I pay a small business for phase 1 and phase 2 research, and then they don't continue on to commercialize it, I (as the government agency) cannot use their research for anything. So I pay $850k, get a whitepaper, maybe a prototype, and then I'm not allowed to use either if the company decides not to go in on phase 3. It's a great deal for small businesses, but a horrible deal for the government when it encounters greedy little companies (of which there are many in the SBIR world).

    Some kind of contractual obligation to attempt commercialization after phase 2 would be nice, and if the company doesn't go for it, .GOV should get the rights to the research (IANAL and I have no idea how this could be enforced). Just my thought as one that was once on the other side of the fence...

    If you like the idea of your tax dollars going to smaller companies, then please let your congressional representative know! The SBIR program has been targeted in recent years by lawmakers who feel that it's a waste of money.


    Disclaimer: I used to work for a government agency that awarded numerous SBIRs. I reviewed proposals, met with the small businesses owners, etc.

    For the most part, SBIR awards go to companies that win a lot of Phase 1 and Phase 2 awards, and then never commercialize a thing. The companies just go on to win more Phase 1 and Phase 2 awards ($100k and $750k, respectively). Companies have little motivation to do more than this, because a team of four or five people can pull down a handful of phase 1 SBIRs (pretty much they just have to write a whitepaper at the end, and the quality I saw was low -- the type of thing that I could write in a solid week if was in my field), or 1-2 Phase 2 SBIRs in a year, and can make a very good life for themselves by doing very little work.

    In the lovely world of government contracting, there simply isn't much we could do to stop this sort of behavior -- I wasn't, for example, allowed to weight proposals based on the company's past SBIR experience, or even on the CVs of the folks that were proposed to do the research. Either the SBIR process has to change a lot, or I do think that it should go away -- the money isn't big, I realize, but the way that it is set up now, it is ripe for abuse at the expense of taxpayers.
