    sssmith, hanging with brcm

    Unless there guys at BRCM are a bunch of flim
    flam guy,WHICH I STRONGLY SUSPECT NOT, then I would
    take the Chief Technical lead at his word when he says
    they have a working technology in VOFDM.

    His
    comments were they have looked at all of the avaliable
    alternatives and finally selected VOFDM.

    I'm no expert
    in this area, but this is what I do know, there is
    no shortage of coding/modulation schemes. The
    biggest problems with broadband/video, is developing and
    efficent implementation (both computationally and
    real-estate wise). This concept of Frequency Division
    Multiplexing is as old as the hills (i.e a recent example is
    cassete recording of programs used two tone modulation
    schemes). The Russians use multi frequency approach for
    GLONASS, the Russian version of out own GPS.
    I am
    hesitant, but on the verge of saying, technically this is
    almost a step backward! Unless soemone else out there
    can fill me in, Multi Frequency has the main benefit
    of providing "Frequency Diversity" which is the main
    advantage in the presense of Multipath.

    Bottomline
    there is nothing in my mind that would lead me to
    suspect that the advantages of (VOFDM) are "cooked" up.
    In my mind this is simply the result of good systems
    engineering in recognizing what the right implementation is
    for this particular problem.

    As far as other
    features, of this technology which allows BRCM to do it
    where others maynot be able to.... Well that is all
    purely execution(see efficieny above). And from what I
    read/see of BRCM they can do that.

    If questions
    about the ability of VOFDM to work are what is holding
    this stock back, then I would say this is a tremedous
    buying opprotunity, because those worries will be put
    aside soon enough.

    • I'm afraid that I'll have to take your word on
      that. I was just giving my take on what I was reading
      in the press. Maybe the press was intentionally
      mislead inorder to give opportunities to buy. Wireless is
      going to be big.

      • Well if it helps any, I have a MSECE (signals and
        systems) from UC Santa Barbara. Have worked in Digital
        implementations since 1980.

        Worked on Missile programs as
        systems engineer for Video link/Command link with alot of
        emphasis on multipath effects and countermeasures. This
        included flight testing with specific objectives to
        measure/quantify/model these effects.

        As a matter of fact the
        main reason for the Link Margin requirement (link
        margin is the excess signal level required to insure
        proper link is trasmitting/receiving) is as a result of
        multipath issues! By far this is the dominate
        issue.

        An effective/efficent implementation like VOFDM is
        almost like "best thing since sliced bread" in this
        broad band arena. Having said that there are other ways
        to slice bread. But having CSCO backing and this
        becoming a STANDARD, will insure BRCM success in this
        market. Remember the best technology does not always win,
        it is the STANDARD that will win. This is the
        lynch-pin to this strategy. IMHO
