Upstream from my understanding is on a different frequency and currently is limited to 3 mpbs upload...
There isn't a problem now but if MVDDS internet becomes popular the availability of suitable upstream frequencies could vary in different parts of the country. You're right that it could be better than at least some DSL and coming from towers should have a huge advantage (if not burdened by unreasonable caps or other stupidity) over satellite internet.
DSL in America has always been a joke. ADSL2+ would have provided millions of Americans with quality broadband.
I agree ADSL2 would have been a better option too bad we could never get the likes of the ISP to install such a system nationwide yrs ago. Also now that fiber has come down in price it too would be a great competitor, but alas again getting any company (caugh... ATT) to build out wired lines is like trying to ride a dead horse in a derby. So IMHO the only thing currently to look forward to is new advancements in wireless and new spectrum that can be used for such at a competitive cost (enter MVDDS) Until we can actually get some real fiber roll out (FTTH) were stuck with this customer disadvantage scenario.
