WiMax does not perform well in non-line of sight situations. It's intended to be a fixed wireless technology, at which it excels, hence AT&T investigating it for backhaul use. Between WiMax (or fiber, T3, or whatever) to the sites and LTE for the siteuser link, we should have a highly flexible and high performance network available to us, even if it does take 5-10 years to get it out. I'm assuming standardization and perhaps early hardware within 5, with real commercial deployment taking closer to 10 years.
While I doubt it will take fully 10 years, LTE is nowhere near being standardized, hence the long timeframes AT&T is talking about. Also, HSDPA and HSUPA can provide what, until last year, would have been considered excellent home broadband speeds in a mobile situation, presuming that AT&T can get the backhaul to the towers in a better situation.
On that front, they have been installing more T1s to some sites recently, but that's certainly no real solution, although HSDPA is already enough for what I need to do. More bandwidth would always be nice, of course! HSUPA will give me uploads as good or better than my cable modem, so it should be passable until LTE is out.
Is Qualcomm seriously working on anything more than what amounts to 3xEV? What they're writing about UMB on Wikipedia seems completely pie in the sky to me, but maybe my expectations are just off. |
