    I'm curious, why exactly did the US, when it was developing standards
    for its mobile providers, decide to go with 850/1900 instead of the
    worldwide standard of 900/1800? Reasonable thinking would lead one to
    believe that a worldwide standard would be the best result, but as it
    is, there are phones that work in one place, but not in the other, and
    vice versa. The same thing apparently is happening with digital radio,
    with the US, for whatever reason, choosing a different standard than
    the rest of the world. By also not 'forcing the market' with any
    standard, you get a mix of at least 3 standards (GSM, CDMA, iDen)
    which are incompatible with each other and can be argued is one of the
    reasons that America lags behind the rest of the world in mobile
    technology, as well as in uses and coverage, and deployment of new
    phones, most of which are sold off-the-street 6-8 months before they
    hit the showrooms of service providers in the US, which basically
    require you to sign a contract to own a mobile phone (It is possible to
    buy an 'unbranded' mobile phone, but they are nothing close to the
    availability of regular home phones), and also have been known to
    remove certain features which could potentially give away something for
    free that they would charge for (like connections to PCs which could
    allow free internet access on the phone).

    I *believe* 1800 MHz was already in use by the US Military.
