    2gbps? The article says 2.4mbps... 2gbps would be really cool :)

      I know, I screwed up when I posted it. Mea culpa. What's an order of magnitude among friends?

      it's not going to stop until you wise up, no it's not going to stop. so just give up.

    This is not 2gbps nor is it "ultrawideband". As we all know, 1xEV-DO is more like 2Mbps, and the story is quoted as saying it "Ultra Fast Wireless", not UWB.

  3. NOT Ultra-Wide Band by univgeek · · Score: 5, Informative

    This is in fact not even CDMA - the voice technology used by Verizon. It is a TDMA technique which uses the fact that data is NOT delay-sensitive to increase the data-rate by waiting out 'bad times'.
    The technology provides a high bandwidth to users who are in 'less noisy' areas, where the signal is powerful, and a lower rate, delayed stream to users who are in 'more noisy' areas.

    The technology is Qualcomm's and they are coming up with a hybrid voice-data called EV-DV where DV = Data Voice).

      The second link in the post clearly states that 1xEV-DO is CDMA. Qualcomm also agrees. Traditional CDMA was standardized as IS-95 and 1xEV-DO has been standardized as IS-856 if you want to read more about the technology.

      Also note that it is 2.4Mbps peak per cell sector, per cell carrier. So if you and your ten buddies are sucking down data from the same base station cell, the 2.4Mbps peak data rate is split between all of the users.

  4. Break Out A Thousand Handsets... by FrankDrebin · · Score: 4, Informative

    ...if you want 2 Gbps. The 1xEV-DO carrier supports up to 2.4 Mbps total bandwidth (ie. you share it with all other users of the channel). Spin it any way you want, it's still better than 14.4k dialup, but a far cry from wireline broadband.

  5. Re:I hate when they define a rollout by hal-j · · Score: 2, Informative
    Hmm? 1XRTT (what Sprint is using for their "3g") is the same technology and speed as what Verizon is using for their "Express Network". IIRC, 1XRTT tops off at 144Kbps. They're talking about a different beast here.

    Furthermore, it's common to roll out a new technology in a few test markets. It's quite a bit cheaper to work the kinks out on a limited scale, rather than do a national deployment and hope for the best.

    BTW, the DC area isn't only home to politicos, it's also a high-tech hotspot.
