BPL Astroturf Is Wearing Out
from the this-space-for-rent dept
Last February, fresh off its bought-and-paid-for report on the evils of municipal broadband, the New Millenium Research Council "think tank" came out with another report heralding the wonder of broadband over power lines. This came despite a long series of failed trails and a noticeable lack of traction that didn't come anywhere near the hype built up around the technology. Broadband Reports now notices that one of the NMRC panelists has noticed that BPL's momentum has stalled. We always thought something had to have momentum for it to stall, but we digress. Another member of the panel is keeping up the hype, but, in true NMRC style, he's the head of a BPL provider, so he's not exactly unbiased. Despite the NMRC's enthusiasm, there's been little beyond trials and deals focused on applications for electric companies rather than end users, and the long-term prospects for BPL remain very cloudy.

Re: BPL may work but the Logistics doesn't
They would probably be interested in footing a one time $300 equipment cost if it meant reliable, somewhat faster internet.
The just have no real viable options and I don't see any arriving soon.

BPL is a problem for many radio services
Here, in California, our State Highway Patrol uses this area. Many public utilitys use this range for telemetry with equipment.
Hams are very vocal about being interfered with, we are a volunteer group with little money to lobby officials. Our bands (or frequency ranges) get tampered with on a regular basis and it's frustrating. BPL may offer something, but think of the cost.
4MHz to 30 MHz is the only range of frequencies that can provide reliable world-wide communications range.
Just my opinions...

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 don’t. 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.”
DS2's technology is well known in the BPL industry for being one of the first proponents of programmable notching in powerline communications, as the best method for addressing potential interference to radio services. DS2’s 200 Mbps BPL technology, available in silicon since 2003, already implements this dynamic notching functionality, which has been tested in the field, in several commercial BPL deployments, and demonstrated in several BPL industry trade shows.
“Other competing technologies have some notches, but they are fixed, including the most advanced designs from followers (on top of that they exhibit performance below 40% our speed). This means that they fall short for the demands of regulators and consumers everywhere from the FCC to the European Commission who require that frequency bands can be selectively notched out, even after the equipment has been deployed. Operators deploying non-DS2 based solutions risk having their equipment withdrawn from the field because once it is out there, there is nothing that can be done to prevent interfence with radio signals. With DS2, however, any issues can be resolved even when the equipment is in the field by remotely disabling problematic frequencies thus complying with today's or future regulatory requirements and automatically avoiding any radio signals in any part of the world". Mr Dominguez placed special emphasis on the radio friendliness of the system.
In February this year, DS2's 200 Mbps powerline technology has been chosen as the baseline technology for the European utilities developing PLC standards to accelerate the adoption of low cost, high performance broadband access PLC. As part of the selection process, an extensive set of tests were performed, including notching functionality benchmarks for avoidance of potential interferences to radio services. In addition, report from Ofcom, the British telecom regulator recognised the significant advance represented “The flexibility of the DS2 product, with its programmable spectrum mask and downstream notching capability, represents a significant step towards a more EMC friendly PLT solution.”
Specifically, DS2 BPL system can implement notches in any frequency band, not only in radio amateur bands. This means that the system can be adapted to changing regulations in several countries. For example, FCC recently prohibited BPL Operators to use frequencies within defined "excluded bands". Only products based on DS2 technology can be adapted to this new regulation remotely from the Operator’s Network Operation Centre, while products based on competing chips would need to replace the hardware in the field.
DS2 200 Mbps the technology which underlies the majority of commercial access PLC and IPTV/ADSL deployments worldwide and has been built into equipment manufactured by the leading US, European and Asian BPL manufacturers. It is used by XDSL/IPTV operators like Telefonica and electricity giants such as Consolidated Edison, Duke Energy, EdF, EdP, Iberdrola and Endesa, to drive their broadband over powerline offerings. As of September 2005, the estimated number of consumers and businesses that enjoy access to IPTV, internet and voice-over IP services is estimated at 500,000, with more than two million homes passed in deployments with more than 30 power utilities world-wide.

New broadband-over-power lines technology kicks off in Bataan
as of 10:17 PM)1/28/06
http://www.abs-cbnnews.com/storypage.aspx?StoryId=28509
BALANGA CITY - A United States-based firm and the Peninsula Electric Cooperative of Bataan formally launched on Friday a new technology that will make use of electric lines not only for electric power but also for Internet connection, telephone lines and cable television.
Nextream Broadband Philippines, a US-based firm with Filipino-American businessman Tyrone Javellana as chairman and chief executive officer, introduced broadband-over-power-lines technology in Bataan.
Ronald Fesalbon, Nextream’s chief technical officer, said the towns of Pilar and Abucay and the City of Balanga, the base of the project, are already on-line and ready for commercial operation before the second week of February.
He explained that with the use of a modem priced at P1,200, one can have Internet access or telephone connection anywhere by simply plugging it to any electric convenience outlet available in the house or at the office.
Fesalbon said that with the use of BPL, overseas call to the United States will cost only five cents for every minute as compared to 40 cents charged by other cell-phone companies.
Penelco general manager Loreto Marcelino said the Bataan electric distributor is honored to be the premier and pilot partner of Nextream in the noble venture aimed at empowering the people in the rural areas.
"Penelco is the first in the country which registered 100-percent electrification for Bataan in 1997 and we are glad to be part of this project that will make Balanga the first ‘wired city’ in the Philippines," Marcelino said.

DS2 200 Mbps BPL technology is working with ARRL L
NEWINGTON, CT, Mar 22, 2006--A demonstration at ARRL Headquarters of DS2 BPL equipment suggests the manufacturer is working to minimize--if not altogether eliminate--interference from its products on amateur bands, ARRL Laboratory Manager Ed Hare, W1RFI, says. Hare met with two DS2 officials earlier this month to discuss the company's improved approach to Amateur Radio band notching techniques. Based upon his observations during a demonstration of DS2's latest generation G2 technology, Hare says he's cautiously optimistic. A spectrum analyzer check of the modem's output showed the G2 modem could attain a notch depth of up to 40 dB.
"While there's no certainty that all BPL products using this technology could achieve 40 dB of protection within notched spectrum, our tests show the capability to do so is there," Hare commented. "This may not prevent all interference problems, but a 10 to 15 dB improvement over the notching used by many BPL systems in place today would be a significant improvement."
In its October 2005 Petition for Further Rule Making in the BPL proceeding, ARRL cited BPL systems using Main.net and DS2 chipsets as among those that lack fixed, permanent notches in the ham bands and "have caused numerous cases of harmful interference to stations in the Amateur Service."
Texas Demonstration Inspires Invitation
Hare says he was intrigued by a demonstration of DS2's latest technology he witnessed last September during a United Power Line Council (UPLC) event in Texas. During his presentation, DS2 Director of Strategy and Standardization Victor Dominguez said that the manufacturer had improved the depth of the notches in its chipset.
Two days later, Hare had an opportunity to see a DS2 system in Houston. Some quick tests showed that although close-in notching wasn't much better than other systems', BPL noise dropped below the ambient noise level deep into the notches. Hare and Dominguez subsequently agreed to have DS2 staff work with ARRL to investigate the company's notching improvements.
Figure 1: The notch depth in this test shows that BPL noise is reduced by about 40 dB in the amateur bands. "This demonstrates that the DS2 G2 chipsets are capable of protecting the amateur bands by 40 dB in a properly designed product," says ARRL Laboratory Manager Ed Hare, W1RFI. "In this case, guard bands were programmed into the notch to ensure that the notch depth across the entire amateur band was 40 dB."
On March 9 DS2 Vice President of Technology and Strategic Partnerships Chano GĂłmez and Product Manager Eduardo Lluna, EA5ETP, brought a pair of modems using DS2's latest-generation G2 technology to ARRL Headquarters. GĂłmez directs DS2's US office in California. Lluna is based in Valencia, Spain. After a tour of Headquarters, the trio got down to work in the ARRL Laboratory's screen room, where the G2 modems were set up. The spectrum analyzer results in Figure 1 for the 20-meter band were typical of all bands measured, Hare said.
"It is good to see testing that shows this implementation of technology has improved," Hare remarked. He said GĂłmez has offered to release application notes or other information outlining how DS2 has been able to configure its modems to achieve a 40 dB notch depth across entire amateur bands.
The DS2 modems also were tested at Maxim Memorial Station W1AW, where they were plugged into outlets in separate parts of the building and set to transmit data. Hare listened on a number of ham bands and on adjacent spectrum. Inside the ham bands, the signal was inaudible, he said.
"Although this was encouraging as a reasonable quick-look test of DS2 modems on premise," Hare cautioned, "testing on a BPL installation using overhead power lines would present a more realistic situation from which to draw firm conclusions." GĂłmez offered to look into ways such tests might be arranged.
GĂłmez said he's happy to be working with ARRL to demonstrate that DS2's chipsets are Amateur Radio-friendly. "We have made a huge effort to ensure that the 40 dB programmable notches in our OFDM chipset provide adequate protection," he said.
According to Lluna, several vendors already have deployed DS2-based equipment in the US, "and this gives them the mechanism to avoid interference problems completely." Feedback from the ARRL "has been invaluable" in achieving that goal, he added.
Exchange of Ideas
Afterwards, Hare, GĂłmez and Lluna discussed BPL and electromagnetic compatibility (EMC) issues and potential solutions to head off most cases of interference. "We had a solid exchange of ideas about the technical aspects of interference problems and how improved notch depth could be combined with other techniques to prevent and correct interference," Hare said. "The DS2 staff has a good grasp of the technical issues involved and believes many of them ultimately can be implemented in deployed systems."
ARRL CEO David Sumner, K1ZZ, concurred with Hare's cautious optimism. "We very much appreciate this dialogue with DS2, and we are looking forward to turning talk into action and solutions," he said.
