Re: FIRST U.S. CITY-WIDE BROADBAND OVER POWER LINE

BPL delivers the same hi-speed download and upload... which in theory, we could use VIDEO-Phone calls without lag or delay in transmission... back and forth !!! Hello, Unknown Investor! Symmetrical bandwidth and network latency are two different things. In theory you could use cable, dsl, wireless, or fiber for video phones as well.
I like the statement in the article about BPL being capable of going faster than ADSL2+ which uses "analogue lines". It's funny how they throw stones at analog lines while BPL uses the worst medium known to man for broadband transmission and continues to struggle with making it work and dealing with the side effects. And somehow BPL's unproven future potential beats what competitors offer today. |

Re: What is the problem with it?
If you want to pick out only one problem with BPL and call it the problem, the big problem is that the utility companies cannot figure out how to make any money using BPL.
The typical BPL trial seems to end early with this style of announcement:
We are ending the trial. It was successful and we learned alot. Oh, and we will not be deploying BPL at this time.
We are left to guess at the reasons why. It could be:
• We could not solve the RF interference problems.
• Solving the RF interference problems made the costs of deployment too high.
• RF interference was not a problem, but the deployment costs are always higher than the costs of DSL (or cable, or FIOS, or ...).
The BPL equipment makers claim that the RF interference problem has been solved. If so, it appears that there is no business model with a high enough ROI for the utility companies. |

Beverly Hills, CA | Is it something to do with the speed, latency, or does it have sort of distance limits similar to dsl?
