FCC Aims To End Debate With Wireless Tests

Posted by kdawson on Fri Sep 05, 2008 10:31 AM
from the can-you-hear-me-n— dept.
narramissic writes "Engineers from T-Mobile, AT&T, M2Z Networks, Nokia, Metro PCS, CTIA and XM Sirius have convened at a Boeing facility in Seattle this week to watch as the FCC performs tests it hopes will quiet debate over a proposed spectrum auction. At issue is the FCC's requirement that the winner offer free wireless broadband services in a portion of the spectrum, a move the wireless industry contends will lead to interference for 3G phone users. The FCC is conducting some of the same tests that T-Mobile, one of the more vocal opponents of the FCC plan, has already done plus some additional tests, focusing on interference between handsets running on the different frequencies. Some of the tests involve using handsets connected to WiMax or UMTS networks running on spectrum the commercial providers would use, and then issuing signals using the proposed new service and spectrum, to determine at what signal strength the proposed service causes the WiMax or UMTS call to drop."

After the FCC's tests mentioned early last month, andy1307 submits word of the FCC's report (released Friday), writing that "the major telcos disagree with the FCC's report that concluded that using white spaces to provide free wireless internet 'would not cause major interference with other services. ... The FCC concluded that sufficient technical protections would prevent major problems.' FCC chairman Kevin Martin's proposal is to auction off the spectrum, with some rules attached. 'Some of the spectrum would be used for free Internet service, which would have content filters to block material considered inappropriate for children.'"
[+] Free Wireless Band Gets FCC OK 77 comments
narramissic writes "Last month the FCC conducted tests to determine whether mobile devices using a new US radio band (2,155 to 2,175 MHz) with free wireless service would cause significant interference with cell phones using a nearby band. Now, the results are in and in a report released Friday, the FCC concluded that 'the analysis shows that an AWS-1 and AWS-3 device operating in close proximity does not necessarily result in interference.' Still, T-Mobile accuses the FCC of basing its conclusions on new assumptions that weren't used when the tests took place. But at least one party is happy: M2Z praised the report, saying 'There is no longer any need for American consumers, the public interest and the FCC's regulatory process to be held hostage as it has been for the last five months by incumbent carriers... who have used unfounded claims of interference to disguise their intent to prevent the introduction of new broadband competition in the AWS-3 band.'"

      "seems to make sense."

      That's the problem... it only SEEMS to make sense. What they really need to do is have a panel of respected and neutral engineers design their own test... one that may not be designed to fail.

      There have been all kinds of laws and other legislation passed because one party managed to convince a government entity of their case by designing a test to illustrate their case.

      One great example is Asbestos... Asbestos, in it's most common uses, was inert and completely safe. Even a lay person could remove asbestos tiles, insulation, etc. with little risk to their health... certainly no more risk than smoking a pack or two of cigarettes. Only those who had frequent exposure to asbestos in an airborn form were ever really at risk.

      So why is asbestos, an extremely cheap and effective substance, banned in the US... simply because a test was designed which demonstrated it was unsafe. But it wasn't unsafe on the floor under your child's desk, or wrapped around a steam line, or insulating a boiler, or any of it's many uses. It was unsafe in some situations which could have been made safe with a few laws regulating it's use, the way it was mined and processed, and a few OSHA standards for individuals working with it daily.

      Just like hemp, asbestos has been banned without reguard to it's value and relatively low risk to the public simply because someone created a test to show that it CAN be unsafe.

      • Kind of like gathering lobster and crab in the Atlantic Ocean I suppose. Those fishermen have the highest job-related death rates of anyone. And we continue to buy such dangerous-to-obtain seafood.
      • Citation please, hemp has not been banned in the US. You just have to import it. What you're suggesting is pretty absurd. Asbestos is known to cause serious bodily harm when used in real world conditions.

        Yes,theoretically if you apply asbestos and don't ever have to mess with it and nothing else disturbs it you are correct. But I know people that work around it and it costs a ridiculous amount of money to handle properly when you do have to disturb it.

        I know it's popular to be a member of the tinfoil elite,

        • I assume by "banned" they meant that you can't grow hemp here, even if it's so shitty that no one would want to smoke it.
      • Asbestos was intitally banned, but that was over turned and it is now allowed to be used in certain situations. So, some new buildings being built, are being built with Asbestos in them.
      • It's more ironic than that. Asbestos is mostly harmless unless you start to remove it. It is mainly the unskilled removal of asbestos, which creates a lot of dust, that causes it to be harmful. This is because only the airborne fibers are carcinogenic, while the bulk form is neutral to human health.

        • Re: (Score:3, Interesting)

          My great aunt died of cancer caused by asbestos exposure. She was only exposed to it through her husband - her husband had preventative treatment, but she did not because they didn't realize she could be exposed through the residue left on his clothing.

          I can't say I know much about asbestos in particular but there are many substances in modern society that are unsafe if misused, but which have the potential to benefit life if they are used properly. Most industrial chemicals fall into this category - many are unsafe if mishandled, but if you start banning them left and right there won't be much of modern society left.

          The question is one of risk vs reward. The problem is that in modern society we've become so risk adverse that we can't see beyond this.

    Somehow I have a feeling that T-Mobile's test will result in the same results for the FCC as it did for T-Mobile. If it doesn't then I would argue that the FCC should fine, or even remove T-Mobile's license as they are obviously not capable of properly executing a test.

    My question is simply, did the FCC engineers study the actual test itself to determine if the test is really worth doing. It might be a standard test case, as such why is it news, if it's not a normal test I would try and confirm that the test itself is not skewed to prove the point.

    It would be relatively easy to create a complex test that appears to illustrate a bad scenerio when in reality is simply takes advantage of some obscure phenomenon. For example, the types of antenna's used, reflection, resonance, etc... could all make the test results say something that is not generally true.

      Maybe that's exactly the point? To find out if their results have any merit or if they apply in real-world scenarios. I don't know how much information T-Mobile has provided about these tests, but there's undoubtedly a completely other level of information sharing when their engineers get together and work on the same test.

    • Two things...

      1. T-Mobile may have conducted tests in worst-case scenarios. It's their network threatened, they might want to present the worst, not the best, possibilities.

      2. As a T-Mobile customer, I would like my service to 'not generally' be interfered with unnecessarily. In fact, I would not like to engage in the struggle to make newly-licensed services not interfere with my service AT ALL. Let's get it right, please? Before we build it? It's bad enough already, ok?

    • My question is why would allowing 3rd party carriers on a frequency cause any more interference than just having a bunch of phones for only one company on the frequency?
      • The free internet frequency is in a much lower frequency. Lower frequencies are stronger but carry less information than higher frequencies, think about big waves versus tiny ripples in a pond. Those tiny ripples can rid atop the big waves but can also be knocked out by them if they aren't smooth. Radio is very different but its a decent analogy.

        • Hmmm..... I thought the complaint brought up was that having 3rd party companies on, say 500Mhz, would cause interference. My question was how is 500 devices from 20 different companies using the 500Mhz frequency different than 500 devices from 1 company using that frequency. However, from your response I'd say the complaint was actually that the high usage of the lower frequencies would break the currently working and non-open higher frequencies, which would make more sense, but I still fail to see how

And, rather then just studying the write-up of T-Mobile's test setup and results, they have effectively said, "Put up or shut up."

There is no magic way to route radio waves, anything in range will pick it up, meaning that portion of the spectrum is tied up.

      I can see issues with latency, range, and capacity.

      Latency because you are making more hops.

      Range because you don't have an elevated tower, so the next person with a phone would need to be close by. Plus, the handsets are low-powered and have tiny antennas.

      Capacity because your little phone can only deal with one or two calls worth of data. Even a 3G phone will hit a bandwidth limit if more than a few calls get routed through it. If you happen to be one of the few phones within range of a POTS connection, you are going to have a large portion of the grid routing through your phone.

      And this is all without even considering the technical challenge of routing everything without contacting a central server. P2P apps can take several minutes to get going in PC land, though it admittedly is a different problem.
