Intel Takes UWB Standard to ECMA

judgecorp writes "The Intel-backed WiMedia group, unable to get its UWB proposal approved as an IEEE standard, has got it published as a standard, by the ECMA group. ECMA has less of a history in network standards, and is more swayed by commercial issues, say critics." From the article: "ECMA, whose members are manufacturers, has published two standards, ECMA-368 and 369, based directly on the WiMedia UWB proposals. These had previously reached stalemate in the IEEE, where they were blocked by rival proposals from Motorola-backed Freescale in a debate that lasted for years. ECMA, by contrast, approved WiMedia unanimously, in about three months."

    This is an interesting article, and one that shows how multiple standards committees are actually better for consumers than just one.

    Intel wasn't able to convince the IEEE to accept their proposal for a standard. The ECMA accepted the standard, but opinions exist (and I agree with them) that the ECMA is more a corporate-shill than a standards committee.

    How will this help consumers? By having the IEEE refuse the standard, other manufacturers aren't going to jump on the standard as it isn't widely accepted. Intel is one of the most powerful corporations in the world, yet a standards committee is preventing them from releasing a product that won't help consumers (which could include businesses of course). This will keep the manufacturers returning to the drawing board to try to find a way to convince the IEEE. Yet the ECMA has accepted the product, which means Intel will release it and attempt to gain consumer attention, which could create a de facto standard without IEEE acceptance. Consumer need/desire is met through not just competition between manufacturers but competition between standards committees as well.

    I'd love to see something similar to this in replacing our FDA. If the IDDD doesn't think a drug is worthy for consumers, a drug company might go to a manufacturer-run testing body. Your doctor and you could make a decision based on your knowledge of who is backing the drug. Today, the FDA is the only body legalizing certain drugs, and I bet millions of people have died before the red tape was navigated.

    As for the UWB idea, it seems that there are numerous competitive technologies, which is part of IEEE's reasoning for refusing the standard. This lets the consumers decide which standard will win out through market forces. Motorola's Freescale doesn't seem any better or worse than Intel's UWB, so I'm sure I'll see both in action in my customer base. The IEEE version may end up being a combination of both technologies.

    This is the free market in action, and this is why technology tends to grow in leaps and bounds, whereas heavily regulated markets take years to wade through the red tape, spending billions in the process.

They transmit in all of this bandwidth at the same time. The result is that the low noise amplifier in the receiver is very wideband and very open to interference.

      Also we in negogations with alot of governments around the world due to the interference issue is a new algorithm called Detect and Avoid. Here is an snippet taken from one of the main WiMedia contributors, Wisiar (www.wisair.com)

      "Detect and avoid (DAA) interference avoidance technology will allow Ultrawideband to coexist peacefully with current and future wireless technologies sharing the same spectrum, such as WiMAX or 3G/4G cellular networks.

      Detect and avoid techniques mitigate interference potential by searching for broadband wireless signals and then automatically switching UWB devices to another frequency to prevent any conflict."

    Are they such a tier 2 player that they will accept anything. First Microsoft and then Intel; sounds like a junior league of technology.

    Does ECMA release its specifications to the public for free? IEEE's are all copyrighted and must be purchased.

      In my opinion, if something is a de jure standard, its specifications should be released into the public domain.

      Correction: Most IEEE standards must be purchased. IEEE 802 does not.

    Yes. That is correct.

  14. Fine but do we know why it was rejected? by RobiOne · · Score: 1

    UWB sounds great until you talk to users of other technologies, and how UWB raises the noise floor level for all other communication devices within the band covered. Not something anyone else wants.

    So do we know why exactly did the IEEE decline to make it a standard? I haven't read the papers, so someone please summarize.
