I thought FIOS had a superior network infrastructure, dispensing with the neighborhood concentrators, which can be choke points. Though it seems that the neighborhood concentrators are only problematic if oversubscribe, and any network infrastructure is going to have similar choke points, just further upstream, which, if not adequately sized, will imposed similar problems. On the other hand, the potential bandwidth from FIOS is way better than DOCSIS, but if there is no pressure on Verizon to upgrade the transceivers on each end of the fiber, that makes little practical difference. When you look at the bandwidth graphs published by content providers like Netflix, the ISP's policies and willingness to properly upgrade its backbone infrastructure seems to have a greater impact on actual realized bandwidth than the last-mile technology used. Several ISPs, particularly those in or soon to be in or near regions where Google Fiber operates, have announced they'll be offering 1 Gbps service to match Google. > But I think a whole lot more construction is taking place > with DOCSIS-3 than FIOS, probably because there are several companies using it > whereas only one company supports FIOS. Well, FIOS is a Verizon trademark. Google Fiber is fiber to the home, and it uses similar, if perhaps incompatible tech. (I've never researched who Google uses for their ONTs.) Doesn't AT&T's "U-verse" product also offer fiber to the home? (I heard recently that lately AT&T has been applying the U-verse branding to their traditional DSL service in areas where fiber service isn't available.) An then there is...

Verizon determined that margins were much better with their wireless business (easy to charge lots per bit, impose caps, and if you already own the spectrum, not huge capital costs), so they made a deal with Comcast where they would sell Comcast TV service in markets not served by FIOS, and Comcast would sell Verizon wireless in those same markets. Welcome to US broadband competition.

I'd be surprised if the hardware for FIOS was really all that much more expensive. It seems like DOCSIS gets its biggest win by repurposing the existing coax that's already in place for TV. The concentrator distribution model should provide some savings too, though the cost of running a trunk line vs. a fiber bundle may not be all that much, if you are starting from scratch. I'd be curious to see what the FIOS vs. DOCSIS cost differences are for wiring up a town that has no existing cable plant. We know Google chose a fiber to the home approach, and they assure us they have figured out a profitable business model for doing this, and are not just offering this as a loss leader or market disrupter. On any case, I think DOCSIS is winning because it is a cheaper upgrade option if you already own a coax cable plant, and broadband companies rarely compete in the same region, so no one is faced with building a cable plant from scratch. -Tom -- Tom Metro The Perl Shop, Newton, MA, USA "Predictable On-demand Perl Consulting." http://www.theperlshop.com/ _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
