Jim,
"I saw an article recently that predicted EDGE at 5 Mbps, but I don't take it seriously."
I don't even take 2 Mb/s seriously, except in those situations that wont be very profitable for the operators, i.e., where teledensities are low and the service is installed anyway. I say this because of the contention attributes associated with most next gen wirelesses, much the same as those found in shared media ethernet, or cablemodem situations.
Where is the broadband demarc? I'm afraid I didn't see that question before. At which Layer? and for what type of subscriber (residential or commercial)?
Some of the most interesting and thought provoking ideas concerning the changing characteristics of the demarcation point can be found at times in the Business Communications Review column by Tom Nolle, president of CIMI Consulting.
This is a very timely question, btw.. esp. for those commercial situations in skyscrapers. Wow, the up the riser situation is a lot farther along than I thought. One should be prepared if moving into new quarters these days to come across someone who stops you and introduces themselves as your "last" of the "last thousand feet" last-mile loop providers on your service. Or, on "one" or several of your services, make that, since different services may constitute different facilities ownership profiles.
When the xLEC hands off in the basement (or wherever the easement might be), you might see up to two more providers intervening (usually only one) bringing you UP (or DOWN, in the case of some fixed wireless broadband providers) and then ACROSS where the twisted pairs for rent (on a month to month lease??!) on the floor belongs to the multi-tenant incubator site manager (I kid you not). Some of whom have no problems nickeling and diming their tenants to death in order to pay for the foosball and espresso amenities in the comomon areas, to your point of termination.
I suspect that this potential exists in high rise apartment buildings (MDUs), too, where the VDSL, or as we've seen here last night, FTT-MDU, could become the domain of a third party provider. In the case of xDSL, the riser could belong to the landlord, the vdsl h/w to the specialized operator, and the fiber loop to the CO by the LEC or wireless op.
Where was Marden's question posted?
