Re: 5 mbps SYMMETRICAL??not entirely sure....all that I know is, is that I have spoken with a guy in Cincinnati about his PBL, and he liked the speeds he was getting.
Anyway, once again, the technology which should ultimately be for the ruralites gets deployed in an area where there is an overabundance of urbanites...*sigh*.
just our luck, we'll probably never see this either. | |

Re: 5 mbps SYMMETRICAL??it is of no surprise; it's just further proof that nearly all corporations ultimately do not care about the customer at all; all their customers are for is money-trees. | |

Only technically clueless people (e.g., FCC Commissioners) argue that BPL is applicable to rural environments. It has the same feasility issues in low-density areas as any other broadband technology, if not more so. | |

I am going to assume you have never been to the Syracuse area based on those comments. Just to clarify, even Syracuse city proper is more of a suburban area than a "real" city. The downtown area doesnt really have any residential areas, and most people live in houses as opposed to buildings. While Syracuse is certainly not rural, the people living in the suburbs of this "suburb city" for the most part have land and room to spare. | |

With National Grid ? I doubt you will see a slow down. They have Carrier class fiber every where. I have worked for them and let me tell you their fiber is definitely top notch, they have a very competent network designer that I have worked closely with.
And It's not even mapped since it's their private fiber, they lease to verizon tmobile and cingular just to name a few, as well as other carriers and Isps. | |

As long as he is NOT broadcasting junk, but trying to contact someone where 1 KW could be justified, then it is not intentional, even if he is doing it to mess up BPL. Remember, BPL is still part 15 and has to accept interference even if the FCC rewrote regulations to allow BPL to pollute the airwaves if they make an 'attempt' to notch the interference. | |

Most BPL technologies these days use adaptive multicarrier modulation, and will just ignore the frequencies you're transmitting on. According the the ARRL, Homeplug-based BPL (like Cinncinati's) don't even use the HAM bands. | |

They can ignore frequencies someone is transmitting on, however unless the equipment has a hardware filter on the front end to reject the frequency, it's going to get a signal that's perhaps 60 - 80 dB higher than what the front end amplifier is designed for. That would likely cause intermodulation and interrupt the intended signals. In a worst case scenario, it would let the smoke out of the amplifier. I know of only one system that has hardware filters on the front end to reject ham band frequencies. The rest are just software filters on the output of the units to provide FCC-mandated notching. | |

In other words, it's easy to design a bad implementation; no argument here. I believe ARRL has done some testing at their facility, and found that operation was possible, at least for some devices, near their transmitting tower. So the blanket assertion that all BPL would be rendered impossible by the presence of a full power HAM transmitter does not seem to be the case. | |

True, though the system in operation at ARRL is the only vendor that has the hardware filters that I'm aware of. I doubt others are going to implement hardware filters as I don't think any vendors have even committed to making ham band (software filter) notches turned on by default. Anecdotal evidence has shown instances where as little as 5 watts can disrupt some systems. However, I do agree that a blank assertion isn't correct. The system at ARRL operates in the vicinity of several kilowatt transmitters. | |

I have seen a wide range of immunity in BPL equipment we have tested. The Motorola implementation operated with nearby 1000-watt transmitters on multiple bands.
ARRL hasn't looked at the immunity of other HomePlug systems. Motorola uses additional filtering to improve its emissions, but immunity improvements come along for the ride.
In a few systems tested, nearby transmitters with power as low as 5 watts took the system down. In one system I tested, it took it down hard, and the BPL repeaters had to auto-reboot and reconnect themselves.
But we took that testing one step farther. First, most of the immunity done to date was done with continuous carriers. So in that system, we took a look at different combinations, and found the following:
With in-band testing, using the same spectrum as the BPL system (even if transmitting in the notches), 5 watts of carrier took it down. The system had to autoboot.
Transmitting outside its used spectrum, however, showed immunity to 175 watts or so.
We also transmitted with single-sideband voice and on/off keyed CW signals. In those cases, though power >5 watts slowed it down, the system did not hang up. At 1500 watts of voice or OOK CW, the system slowed but didn't hang up.
The bottom line is that although there were some immunity issues, when tested using multiple modes and in-band vs out-of-band signals, the result was not devastating. A 5-watt CB signal would have taken it down hard. But a 50-watt low-band VHF signal would not, if they were not using the same spectrum. A 5 watt Amateur digital signal would cause it problems, but a 1500 watt voice single sideband signal would cause only latency and speed problems.
The latter could be quite significant, as applications such as live streaming video or voice-over-internet-protocol would probably suffer from intermittency.
I am not identifying the manufacturer involved because we had a verbal non-disclosure agreement with them, and because I know that they took these results and have already made improvements to their product. I want to re-test the product, but it would not be useful for ARRL to publish data on a product that is almost certainly going to be better.
Still, the results with "real" vs just carrier signals is an interesting and useful additional data point.

My question about BPL is?My question about BPL is?
At what point in the local power grid, does it go from fiber to wire. Would it start at local neighborhood electrical substation site. Say where 115 Kv power is stepped down to the feeder line level.
Also what type of carrier wave. In the electrical power system is being used. And what type of impact does it have MF and HF bands. This is where AM radio and HAM radio is found. | |
