Calif. regulators OK broadband over power line test

Broadband service providers got the green light from the California Public Utilities Commission on Thursday to test broadband over power line (BPL) technology, paving the way for a third option in the high-speed Internet market.

The technology known as BPL uses the existing utility lines that deliver power to carry broadband signals into the home. For years, people have hoped BPL would allow electric companies to become a viable third alternative to the cable and telephone companies providing high-speed access to the Internet.

But technical limitations and a bad habit of interfering with local emergency radios have made BPL a tantalizing near-miss for the tech industry.

Nevertheless, several utilities across the country are looking into deploying BPL, and several big technology companies, such as Google, IBM and EarthLink, are investing in the technology.

Last year, Google invested in a service provider called Current Communications Group, which is testing broadband over power line networks in Ohio and Texas. And IBM is partnering with Houston-based power utility CenterPoint Energy to build a BPL network.

EarthLink has tested broadband over power line services with several power companies including Duke Power in Charlotte, N.C., Progress Energy in Raleigh, N.C, and Consolidated Edison in New York.

BPL also can be used to monitor the health of the power grid. If an outage occurs, the network, which is based on Internet Protocol, can immediately send alerts. Eventually, a utility could even use the network to remotely read meters and switch power on or off.

BPL in California, no problem!
Just operate during the inevitable summer roaming blackouts
(You got emergency power right?), the occasional major
earthquake (Us hams might become _useful_ to society again.),
or away from civilization in your car/RV (Where you can pollute
the wilderness with discarded Twinkie wrappers.).

In satire, of course. -sigh-

BPL is ghey
BPL is only being pushed because so many people are stupid enough to believe that if they have electricity, they will be able to get BPL.

This is not true. They can't run the service over high voltage lines.

They have to fiber out to medium voltage (7,200 volts) lines and then offload from fiber ($$) to the unshielded lines.

The lines may be 7,200 volts, but to comply with section 15 the data is transmitted somewhere closer to 1 volt.


Emergency frequencies tend to be low because the low attenuation rate allows for greater travel. BPL being sent at 1 volt attenuates quickly so their workaround is to use EMRGENCY FREQUENCIES to transmit data on the power lines.

Even at 1 volt it is enough to disturb radio and emergency communications because med voltage power lines are basically a big antenna.

The problem with being only about 1 volt is that the signal must be cleaned and re-amplified every few hundred feed (more equipment, $).

medium voltage lines are stepped down to 240 volt drops to peoples homes but the data could not survive this. The result is the need for a CT coupler (yes, more $) to bypass the transformer and again reinsert the signal onto the shielded line.

When all is said and done you have a service that is expensive enough to run that it will no be a rural broadband solution.

At best it will be available to areas that already have a choice between Cable, DSL, Fiber, and soon WiMAX.

For the high maintenance costs of keeping BPL signal leakage from PBL deployments you could just run fiber right to the home.

Also, BPL maintenance and inline equipment = network (read Power) outages.

Besides, internet access is a very step for power companies. By the time they establish data centers, mail platforms etc. there will be a slew of better alternatives that won't cause power outages.

Maybe they should instead focus on providing reliable power service or clean energy.

As for the latest "We can monitor equipment with it" they already have technology in place to do that that. It is simply their latest ploy to get people to sign off on their raping the radio spectrum.

BPL is far from "ghey"
I've researched the BPL technology a couple mounths ago and I found that it is very reliable, and is also economical. I know there will have to be repeaters every so many yards, but DSL/CABLE also has repeaters every so many yards. The truth is, you have outlets all over your house, so why not just plug in your modem instead of having to run wires from your phone or cable jack, and the wire to your power outlet. Rethink the idea, also emergancy signals are not effected as much as you say they are, the only people complaining about the effects of the signals is ham radio people, and they have not even been effected! Nor will they be because the technology can only get better... Thank you.

DS2's Radio Friendly BPL Technology puts Competition on the Defensive

Speaking at 2005 UPLC Annual Conference, Victor Dominguez, DS2's Director of Strategy and Standardization, outlined the reasons why DS2's 200Mbps powerline solution is the only regulatory compliant technology available for BPL commercial deployments.

Dominguez was dismissive about claimed alternatives to DS2.

Mr Dominguez was adamant about competitors claims "I think that we have put the competition on the defensive. Our competitors would love to have the flexible notching capabilities that we have for BPL and In-Home PLCs, but the truth is that they dont. DS2 has had dynamic notching since its first chip set and can mitigate radio interference in a programmable way and other PLC chipsets do not. We would like to thank our competition for the rumours propagated at several press interviews, they have been attracting attention towards one of the main competitive advantages of our technology, we mastered programmable notches in a 200 Mbps chipset more than 2 years ago, since then we have been shipping in volume for BPL and In-Home applications, and still remains to be proven that competition can follow us.

FCC: MANASSAS REPORTS NO INTERFERENCE/ANNOUNCES G2 UPGRADE
Tuesday, April 18, 2006


In response to a complaint by an amateur operator, COMTek reported to the FCC this month that an independent FCC-certified testing laboratory could find no interference attributable to BPL in the specific ham radio frequencies. According to COMTek, the testing lab conducted on/off tests of the system, and found an almost identical level of interference in the ham bands covered in the complaint to the FCC, regardless of whether or not the BPL equipment was in operation. This means that, while ham radio operators may have detected the interference reported to the FCC, it does not appear to arise from COMTeks BPL operations. In response to COMTeks news release, ARRL posted a story to its Web site quoting the local amateur operator that the interference is still there, basically ignoring the larger question whether the interference is from BPL. ARRL didnt attempt to explain why the report measures an almost identical level of interference even when the BPL system was off. Instead, it criticized the type of equipment that was used to measure the emissions, and noted that the report is preliminary. For its part, COMTek said that it will continue to test in the coming months.

COMTek also announced that it would upgrade all 600 of its overhead BPL devices to G2 in July. COMTek Vice President, Walt Adams said, The COMTek decision to upgrade its overhead BPL equipment in Manassas reflects our longstanding commitment to provide the best available hardware and services for our rapidly growing customer base. BPL in Manassas is a real success story that shows that the 'first wire' to homes is a viable means of delivering affordable broadband to homes and businesses that otherwise face limited alternatives and unnecessarily high prices. The G2 equipment reportedly uses a modified HomePlug chipset that delivers 14 mbps and includes features such as QOS for VoIP. The G1 equipment uses spread spectrum and is not interoperable with the G2 equipment. It also disclosed that it expects to announce that it has reached the 1000th customer milestone in Manassas during the spring or early summer of 2006.

Meat in a can, and my response.
Ambient Corp (ABTG.OB) has gone from $11 a share in 98 to .19 cents a share.

From Yahoo's insider transactions page (<a class="jive-link-external" href="http://finance.yahoo.com/q/it?s=ABTG.OB" target="_newWindow">http://finance.yahoo.com/q/it?s=ABTG.OB</a>) it looks like nearly everyone in the know is planning to dump what is left of their stock.

The company is several (6.5) million in debt (source: <a class="jive-link-external" href="http://finance.yahoo.com/q/ks?s=ABTG.OB" target="_newWindow">http://finance.yahoo.com/q/ks?s=ABTG.OB</a>) and the "Net Tangible Assets" for the entire company are literally $50,000 (source: <a class="jive-link-external" href="http://finance.yahoo.com/q/bs?s=ABTG.OB&#38;annual" target="_newWindow">http://finance.yahoo.com/q/bs?s=ABTG.OB&#38;annual</a> )

The inventor of that patent (and all other Ambient Corp patents) "Dr. Yehuda Cern" is now 62 years old and will likely be leaving with a severance package worth more than what is left of the company.

I guess there is a reason you have resulted to spamming.

As for your other posts, one of them tells one side of the story in a conflict with a BPL trial and a some random Ham operator. The other is a press release which I am _sure_ gives a 100% accurate representation of technology they are attempting to sell.
