I forgot to mention that munchkins are high speed enough to make the
"last mile" in bandwidth a nonissue.

> And in a related development brought to our attention by John Rowlett:
> Local Multipoint Distribution Service (LMDS) is a new wireless
> service developed by the NJ firm "CellularVision Technology &
> Telecommunications" (CT&T). LMDS operates in the 28 GHz range with
> a 6-inch square antenna, using 1 GHz of spectrum for "cellular TV"
> services (essentially wireless cable), and another 1 GHz for a
> broad array of wireless digital data -- everything from Internet
> connections to telephone and even videophone calls. Of particular
> interest, LMDS is a 2-way service, providing a return path (from
> the subscriber TO the head end, and hence out onto the Internet)
> by using cross polarization techniques. CT&T expects to roll out
> service in the New York metro area within the next six months.
> And, based on a new wireless modem developed by the Israeli firm
> New Media Communications and licensed to CT&T, the Feb. 24
> Business Week indicates that data services over LMDS can be FAST
> -- up to 54 Mbits/second (although CT&T's "Futures" page suggests
> a limit of 25 Mbits/second). Details are at
> http://www.cellularvision.com/homepage.nf.html .
> Of course with any shared services such as these (where each individual
> user does not have their own dedicated pipe), it remains to be seen how
> well each service actually operates in a real-world environment. But
> regardless of how well (or poorly) these individual wireless data
> services actually perform, they represent important examples of the
> innovative competition that, in my opinion, is going to guarantee high
> speed and pervasive access to the Information Highway for those who
> want it.
> It also makes me think that, with competition like this, the
> established phone companies will have to provide their own higher speed
> offerings sooner, rather than later, if they wish to leverage their
> massive copper infrastructure.
