    I try Verizon Lumia 822 on ATT's network. Kind of wired. But voice quality is pretty good.

    I think WiMax in NYC is owned by NYC Government.....And they are really fast.

    How much did you paid for that T1 in your dorm in 1998? $1000/month?
  4. dnwk
    Wasn't that 800Mhz is for roaming on Verizon?

    As my traceroute shows, they dump most of their transit route to Level3. Why not using SprintLink? This is something I don't understand.
  6. dnwk
    Oh, That's why a Sprint Hotspot's WiMax is so much faster than Clear's home modem

    As far as I go over wikipedia on Rev. B. Looks like Rev. B is faster only because of carrier aggregation. And sounds like if Rev. B is deployed on Sprint, it will only increase the congestion.

    There was a World called GSM. There was another World called CDMA. The world was divided. But now, they are united under LTE. Surely I know there are FDD LTE and TD-LTE. But it was not fundamentally different. .

    It might not be the reason. I tried Verizon's service. They have 800 on CDMA and doesn't seem like they have better voice quality than Sprint.
  10. dnwk
    I guess bigger speakers and stronger signal may be the reason.

    Is iDEN's voice quality superior than CDMA? That's what I feel like. Not sure if others feel the same.

    I though Lightsquared were dead......now it came back as vampire

    Did Sprint use any of G block prior to LTE?

    It is not a technical question. It is a philosophical question.

    How is the WiMAX in Columbus?

    What's the problem with new Airave? I did not experence any problem. And new Airave give me 3G instead of 1x.(Although I could simply turn on WIFI)

    In the end, the question will be, do we really need a 1Gbps speed on cellphone.
  18. dnwk
    Maybe Robert should have a FAQ session. So that I won't need to ask every question you have wrote before.
  19. dnwk
    And probably we will see that all come to true in 2023 at the current pace.

    I know Verizon/ATT were huge and have the power to (do whatever they feel fit). One thing I don't understand is, while GSM carriers embrace HSPA+, why no CDMA carrier embrace EVDO Rev B
  21. dnwk
    But that doesn't work out for clearwire, though they were first into WiMAX
  22. dnwk
    I was thinking when a carrier deploy a new technology. And only after two years they need to do upgrade. Is it really good on ROI?
  23. dnwk
    Post a picture
  24. dnwk
    For Verizon using LTE Release 8, how difficult it is to upgrade to LTE-Advanced? Does it needs cellphone side support?
  25. dnwk
    Please point me towards that direction.
