| while BPL can cause interference, if properly set up, it will not. Have any of you read any of the information about low-voltage BPL?
I might also at that the ARRL has BPL set up at their HQ in Connecticut, and has not experienced any problems.
Still, I'm not praising or damning this technology just yet...there needs to be many more tests run with the low-voltage BPL. |

Yes, but the ARRL has a Motorola system, and Motherola understands radio *far* better than these fly-by-night outfits. They (Motorola) also worked closely with the ARRL when the system was being designed, and specifically avoided frequencies that were problematic.

Still, I'm not praising or damning this technology just yet...there needs to be many more tests run with the low-voltage BPL. The system at ARRL HQ notches out the ham bands and uses hardware filters rather than just software filters like all the other manufacturers. They also only use the low voltage part of the power lines (after the transformer), and not the overhead lines like all the other systems. The low voltage system there is good for ham radio, though it doesn't do anything for the other 90% of services on the bands, just like the notching you see on other systems, so it's not a silver bullet. And the majority of systems in the field aren't like the system operating at ARRL HQ. I do think BPL on overhead high voltage lines is a losing battle, though, and a low voltage system has more potential. But don't expect it to blow the doors off of FIOS or even cable and DSL anytime soon. |

Which I totally agree with, and think most people either don't know, or are misled to, about. They think "Internet over powerlines", and figure it's a great way to have access anywhere you have power, especially out in the sticks. The problem is, is that it doesn't travel all that far, and to *really* get it everywhere the power goes, you'd need to build _another_ infrastructure on top of the existing power system.
It's just a loser of a system for high-speed data transmission, and yet the FCC keeps pumping away at it. Another good example of the FCC going down the tubes when they put *politicians* in charge instead of Engineers.

| Powerline broadband is a joke...
BPL is a four letter word, "joke". The interference will become a factor at some crucial point if it continues using the same unshielded lines. I just wonder who the idiot was who thought this would work. I mean, park under high tension wires, and you already hear the interference in the AM band, and thats without any carrier noise, just high voltage. Add carrier noise to that line, and I could see where it could splatter interference. Why would someone bother with this slow crap when the other options available are cheaper to deploy anyway. Why doesn't the people who are REALLY interested in faster internet write their government officials and demand it, or simply move to a better suited area.

BPL providers should use newer BPL/PLC gears that are ham-friendly and used by well-known Utilities and passed international standard. Do research more on Broadband over Powerline !!! |

Re: DS2 200 Mbps BPL tech is working with ARRL Laboratory !!!
said by BPL 200 Mbps :Hope this will give light to the matter. Congratulations on making a post that promotes your favorite chipset manufacturer and at the same time is on topic, all while using only nine exclamation points, not counting your sig line.  You've come a long way since your anonymous days »Earthlink uses Ambient BPL modems
Note that the system in operation at ARRL HQ is Homeplug based, not DS2, but DS2 did meet with ARRL. I haven't heard anything since; are they still working together? It would be nice to see a DS2 based system operating at ARRL HQ. Considering that there's several manufacturers using DS2 chips, I wonder why there isn't one of those systems operating there for testing. |

| re: "DS2 provides a special mitigation technique called "Notching" which ensures that no interfering radio signals are produced at the critical frequencies used by short-wave radio. Notching has been a key requirement of recent rulings from both the FCC and the European Union. The flexibility of the DS2 product, with its programmable spectrum mask and downstream notching capability has been tested by the British Telecommunications regulator (www.ofcom.com) and has been praised in a published Ofcom report as a " a significant step towards a more EMC friendly PLT solution."
