    earth, for now.
    Ok, so there has been alotta talk about the poor 3G service with AT&T, over the years with the iPhone... ((( Mind you, I live in Canada, so I dont hafta deal with that noise -- I have Bell Aliant service, and it's crazy insane good, and I lie 25KM outside the Capital of New Brunswick )))

    Is this true...?? (just my thoughts)

    The reason for the many dropped calls is because of the radio transmitter within the iPhone.

    When the iPhone is in call, on 3G, the Radio NEEDS to maintain a steady connection with 3G in order to maintain the direct call. Unlike other phones, where if the 3G service is not available, it downgrades to other frequencies such as CDMA, 1X, EVDO (or wutever else) in a manner which it keeps the call active... with the iPhone, the radio transmitter doesn't make the switch in a timely fashion that allows for the call to continue, thus is drops. And when a user then Re-dials a call shortly after, and can't get the 3G service, it then bumps the call onto one of the lower frequencies?

    Now, say.. if a user makes a call, and is on a CDMA/EVDO/1x service, and then enters a 3G service, does it upgrade to the 3G? (if it does, I wouldn't assume it would drop)

    If the statement above is slightly correct, then would it be safe to assume that with the iPad 3G, it WON'T have the same conflictions because it's not a 'CONSTANT' connection needed... meaning if your loading a webpage, and the service cuts out breifly, the iPad just pauses, and waits for the direct connection and then resumes, and depending on the 'pauses' this may happen quick enough that most users won't notice the delay in Connection establishing with the 3G service.


    AT&T just has really poor service. Period.

    Just my thoughts. Random. I know.. but just curious what you think about this... Leave your comments.

    Interesting point. Thanks for that.

    I was wondering whether Apple's choice not to include a camera in its first Generation ipad was due to the US GPRS/3G network short-falls, particularly the bandwidth limitations of AT&T's network (I hope I worded that correctly- Not a network Tech expert- But you get my point) .. There have been a lot of reports here in Europe of networks in North America not coping with the iphone traffic. Would the demand of video calling on iphones & ipads crash the present network? It would be a shame to have denied European customers such an obvious addition to the ipad because of AT&T's poor network infrastructure.

    Well, we really won't know about bandwidth limitations. Rumor has it 4th gen iPhone has video calling, so that throws that theory out the windows.

    And they could have still included it, but said it doesn't work over 3G, just like a ton of other stuff they blocked from the 3G network.

    No offense but that really doesn't make too much sense. Yeah, having a camera would probably increase bandwidth consumption as people send the images, but I doubt to the level that it would impede the network. Personally, I don't see a need for a camera, either front facing or one on the rear. While many people have whined about the lack of a camera, I see no issues, but that's just me.
