join:2005-05-17 | I'm curious. I'm not trolling or trying to be snarky on anyone. I don't know too much about this, and I'm asking honestly.
If BPL isn't the answer (and the comments here present strong arguments to that effect), what is the BBR community consensus as to what would be a better technology to push for the rural areas that don't currently have access? It seems that every technology solution that comes up either has major pitfalls or extremely high pricing requirements. Do we have the silver bullet yet? What should we be looking at?

| There are a lot of solutions out there. Licensed WiMax or proprietary protocols, 802.11 mesh networking, increased DSL or cable deployment... all of these would work. Personally I'd say an 802.11 community network with WiMax or fiber backhaul would be the best solution, but the concensus is either purpose-built wireless or better wired options.
BPL's problem in rural access is that it requires the same things as other wired options, like repeaters and backhaul, AND it is technically flawed, especially for rural areas. Many rural public safety systems still operate on the VHF lowband around 40 or 50 Mhz, which some BPL systems interfere with as well.
Thanks for actually asking a good question, I hope I've satisfied your curiosity. |

said by Sabre:... What should we be looking at? wireless, of course, but I think the govt should use the USF to build out broadband to all areas where the ILECs won't do it. Right now, the USF is a several billion dollar a year waste of money. |

It seems that every technology solution that comes up either has major pitfalls or extremely high pricing requirements. Do we have the silver bullet yet? What should we be looking at? One should not look to BPL as the answer, due to BPL's price requirements, along with the interference problems it causes. Consider the cost to run BPL.
Repeaters and the BPL equivalent of DSL DSLAMs will need to be deployed. BPL service is provided by a DSLAM/Cable headend type device, but its effective distance is 200 meters or 656 feet.
Every 200 meters a repeater must be used to regenerate the signal. BPL service can't really be distributed from a central point like Cable or DSL, so the upstream Internet network must be backhauled to each BPL feed point via telco facilities such as fiber or copper.
Some who have delusions that BPL is a humanitarian effort to deliver the Internet to huddled masses of rural folk starving for bandwidth are overly idealistic and unrealistic. This is a business with one thing in mind - revenue.
Q: Why won't BPL be economical in rural areas?
A: Let's do the math for 10 people per mile of powerline with BPL...
Assume:
CPE cost: $500 each
Repeaters: $1K each
Customer Take Rate: 30%
Backhaul cost: $1k per month (a T1)
Repeater distance: 600 feet
Feedpoint cost/misc routing equip: $5k
Revenue per customer per month: $40
So:
Number of repeaters needed: 8
Number of customers: 3
Nonrecurring cost: $14.5k
Nonrecurring costs over two years: $604 per month
Recurring Cost: $1k per month
Revenue: $120 per month
It's easy to see that rural BPL isn't profitable.If anything it's a pyramid scheme to con investors out of money.to deliver broadband in areas that cable and DSL don’t so there will be no competition to drive down prices. The costs to deliver to these less populated areas will be higher, so the motivation for low prices in these area is absent. But it’s likely BPL will be deployed exactly where cable and DSL is now because that’s where the revenue is.
BPL is not going rural any time soon. In fact BPL will be deployed exactly where cable and DSL is now because that’s where the revenue is. It'll prove itself to be to costly a venture with no ROI short or long term.
Because, If you don't have broadband now, there's probably one good reason - lack of sufficient revenue in your area.
