| Solid tech, solid revenue model at $30 For all the hysteria and overreaction on this thread, I wonder if anyone cares that the Main.net tech has been certified as Part 15 compliant by an FCC accredited laboratory in actual field conditions.
Also, for you folks who just can't see how any broadband service could be offered for $30, let the adults handle the business model. Prospect Street Broadband, a privately held company, has plenty of investor money behind them to build a national BPL brand. Incidentally, PSB is a subsidiary of Prospect Street Ventures, a Wall Street VC firm.
The technology simply isn't that expensive to deploy and maintain. Once Manassas is live, and point sources of RF leakage are plugged, interference will be within FCC limits, no better or worse than garage door openers and baby monitors.
So there's my response to the claims of no technical data to support non-interference (which involves proving a negative, BTW), and to the ludicrous objections on the financial side.
YES, I've seen the Manassa revenue model, and NO, I will not share it just to satisfy BPL detractors that enjoy hurling insults and invective at a emerging technology they fear exploring and developing in the USA.
That said, BPL is only an interim solution until FTTH is available. The idea of a massive federal program is stupid. Broadband is being deployed by the municipalities in rural areas, just as the power grid was in the 1930s. No giant (wasteful) federal government program was required then, and none is required now. | |

Norfolk, VA | Re: Not so solid tech model Ok so go ahead and invest your hard earned $$ in Prospect Street. Here is what I predict will happen:
1. Prospect Street gets a significant roll-out done in Manassas.
2. FCC receives complaint of interfence from FAA to the Potomac TRACON Center (uses HF radio for long range air traffic communications).
3. FCC shuts down Prospect Street until interference to air traffic control is resolved.
4. Prospect Street and City of Manassas(not to mention subscribers) wind up in court over a long term contract for technology that FCC will not permit to operate.
5. Prospect Street/Main.net stock tanks.
There is no way I would put my hard earned bucks into investments in this flawed technology. Solid revenue model? Maybe so, but when the service gets shut down for technical, not financial reasons, it will matter not one iota that they had a solid business plan. | |

You really don't understand this technology, do you? There are NO point source emissions in this BPL system. The WHOLE power line grid radiates! It is NOT a point source emission, as a cell phone or hand-held tranceiver is a point source radiator. To stop the emission, you have to shut off the RF feed to the system, and thus remove the RF from the antenna (in this case, many 10s of miles of power lines).
A cable system or telco system with twisted pairs, is a closed, shielded system and would thus contain some "point source leakage". The power system is an open, unsheilded system and the whole thing radiates when RF is applied.
My friend, I fear you are buying into the industry hype! | |

Hilarious! You say part 15 like it's worth something. LMAO!!! I guess you bought into all the BPL "techno babble" out there.
Kid's walkie talkies are part 15 and so are toy rc cars and cordless phones. That imparts alot of confidence there, LOL!! Part 15 is the easiest type acceptance there is.
Basically any Chinese made piece of consumer crap with a transistor in it is part 15. The FCC hands out the Part 15 certs with minimal testing because they can shut it down at the drop of a hat. Sounds like a solid investment to me, NOT!!
Familiarize yourself with RF compliancy before you stick more of your foot in your mouth. I've been in the RF and compliancy biz for nearly 15 years, part of it with Motorola.
If it was worth a damn it would have a different type acceptance and require a blanket license much like a business Part 90 for commercial equipment etc. Of course they can't qualify for something like this because of the nature of the technology.
Cable television uses many frequencies in the aircraft, public safety, and amateur bands but it is contained in a shielded cable and causes no ouside interference. BPL is in the open with no shielding, it's a big antenna. There is no "patching" of isolated RF leaks because the whole thing is an antenna! This is why amateur radio transmissions cause BPL users to lose their connection.
There's nothing there to keep the outside world out of BPL, just like there's nothing to keep BPL in. Should be a great haul for credit card scammers since your data isn't secure because it's just floating around out there.... Oh, but we won't get into that, I'd hate to hurt BPL's chances of being implemented. LOL!!
Considering I'm "licensed" for Part 97 and I don't have any radio telescopes in the vicinity, I'll just run one of the many 24/7 CW beacon stations found throughout our bands for propagation reports and no one will be able to use BPL in my area. Problem solved. Legally too. Why? Because Part 15 may not cause harmful interference, and MUST accept all interference. The FCC always sides with "licensed" users.
Personally I don't think we'll see BPL implemented in this country any time soon. At least not as the Part 15 kludge that it is. Anyone who would invest serious funds into a Part 15 network needs their head examined. Part 15 is too susceptible to being shut down on a case by case basis by the FCC. As for being cheap to implement... BPL is the kid's walkie talkie (the dollar store kind) of broadband. Sad, but true. | |
