Will 5G Save Broadband Over Power Line?

Will 5G Save Broadband Over Power Lines?5G could resurrect broadband over powerline (BPL). At least that is the hope of AT&T (T). For those who don’t remember the heady rise of BPL, it grew out of an attempt to use the existing electrical grid to deliver broadband everywhere without having to build infrastructure anywhere. A few broadband over power line systems with paying customers got off the ground but they were all gone by the end of 2010.

ATT logoAT&T started testing BPL renamed Project AirGig in 2016. And now in 2019 FierceWireless is reporting AT&T is planning more trials of AirGig that will involve 5G. The telecom behemoth is also working with vendors and technology partners to build commercial-grade 5G equipment for those trials.

Hank Kafka, vice president of access architecture and standards at AT&T, told FierceWireless the company isn’t ready to offer details but said Project AirGig is making progress and it will be a very complementary technology to 5G. He told the author that “5G is very high on that list.”

Specifically, AirGig could be used to extend 5G millimeter wave (mmWave) signals beyond their current range. The article says AT&T has launched a mobile 5G service in 19 markets so far using mmWave spectrum, but using that spectrum has drawbacks because it has a limited range compared to lower spectrum bands.

Air5G small cellGig technology includes a radio distributed antenna system (RDAS) and mmWave surface wave launcher. The RDAS reconstructs signals for multigigabit mobile and fixed deployments. The mmWave surface wave launchers can power themselves using inductive power devices without an electrical connection. These devices then create a high-speed signal that travels along or near the wire, providing a broadband connection.

I covered AT&T’s 2018 AirGig trial here. In that trial with Georgia Power Company, the telco used LTE as the transport technology.  Mr. Kafka explained that in 2018 suitable 5G equipment was not available. “At the time of the trial 5G equipment was large and bulky,” he said. Now that 5G is commercially deployed in some markets AT&T is working with vendors to get the right type of gear for the new trials.

Not only could AirGig potentially extend the reach of 5G, but it could also be used as a backhaul technology. “If you set up an architecture where AirGig is connecting to 5G radios, it is acting like backhaul … And you can get gigabit speeds and beyond.”

5G backhaulHe also said that commercialized AirGig would be a good fit for small cells because of the way it is architected. In other words, a wireless signal could travel down the power line and handoff to small cells or be used to backhaul wireless traffic from small cells. This could be profitable for carriers who are getting resistance from municipalities over the siting of their small cells for 5G. AirGig might allow small cells to be co-located with utility infrastructure.

Apparently, AT&T doesn’t have plans to commercially deploy AirGig in the near term, but it has rolled out 5G service in 19 U.S. cities that could benefit from the goals of the BPL AirGig experiment including:

  • CA: Los Angeles, San Diego, San Francisco, San Jose
  • 5G cell phone userFL: Jacksonville, Orlando
  • GA: Atlanta
  • IN: Indianapolis
  • KY: Louisville
  • LA: New Orleans
  • NC: Charlotte, Raleigh
  • OK: Oklahoma City
  • TN: Nashville
  • TX: Austin, Dallas, Houston, San Antonio, Waco

Maybe AirGig is on the slow track because there aren’t any smartphones that can use it yet. The Verge points out that AT&T’s only available true 5G device is a mobile hotspot that can’t be purchased in stores.

Big Blue Props Up Broadband over Powerline

Big Blue Props Up Broadband over PowerlineBig Blue continues to support Broadband over Powerline (BPL) as a way to close the broadband divide in rural areas. According to an IBM Global Financing press release the division has established a financing agreement with DS2, a supplier of integrated chip technology for powerline vendor International Broadband Electric Communications’ Broadband over Powerline Regenerating Unit (BRU) smart boxes. The BRU’s are attached to an electric utility pole to provide high-speed Internet signals to residential customers via the electrical drop. IBEC is working with rural electric utility cooperatives to extend broadband access to ‘unserved’ customers mainly in the South, East, and Midwest.

This is not Big Blue’s first major BPL investment. Even as many industry pundits were reading BPL its last rites, IBEC signed a $9.6 million agreement with IBM to deploy BPL networks in Eastern U.S. electric cooperatives. The investment was heralded by the Utilities Telecom Commission (UTC) as a “major step forward in bringing broadband services to the residents of rural America.” At that time, IBM and IBEC said they were working with the Midwest Energy Cooperative to deliver broadband over powerline to area residents and businesses throughout the seven counties the utility serves.

The End of BPL?

The End of BPL?DSLReports has an article citing the death of Broadband Over Powerline (BPL). Apparently, the first U.S. city to see a non-trial launch of BPL in Manassas, Virginia is shutting down. Comtek, the company that originally built the network, is giving up on the installation after a planned sale to Smart Grid LLC fell through and the city has taken control of the network.

The End of BPL?BPL has had difficulty gaining traction for several reasons. First, its relatively slow throughput in the face of next-generation speeds and its potential for interference with amateur and emergency radio. Finally, many utilities simply didn’t want to be broadband providers.

Last May, a BPL trial operated by DirecTV and Current Communications in Dallas, Texas which had hoped to offer BPL service to 2 million residents was sold to the local utility.

City First in Mich for Broadband Over Powerlines

City First in Mich for Broadband Over PowerlinesFrom Hometownlife.com Grand Ledge Michigan is the first city first in the state to get broadband over powerlines. A New York company is opening an office in the city to be the first in Michigan to offer broadband access to the Internet over power lines.  The high-speed system will be available to the city’s businesses and residents in early to late spring.

The service will be offered by David Shpigler, president of the Shpigler Group, a consulting firm that specializes in advising utility companies. The company is changing directions and is becoming more of a service supplier. The launch of the technology is one of many similar business ventures around the country.  Grand Ledge was selected to be the first place to deploy broadband over powerlines technology because it is centrally located and because it is served by Consumers Energy. “This is a commercial venture. We are also considering expanding to St. Johns and then evaluating it before launching the service in the rest of the state,” Shpigler said.

“We are working with vendors to be able to have the latest and greatest technology and be able to offer the fastest speeds,” Shpigler said. BPL technology allows a broadband signal to travel on a power line and connect computers to the Internet. A customer connects to the service using a special modem inserted in an electrical outlet instead of to a telephone line or to a cable wire. The company will have a local office at 203 S. Bridge St. in downtown Grand Ledge.

The cost to residential customers is expected to be $29.99 monthly, Shpigler said. Higher speeds and additional services will also be made available to local businesses on a “built-to-suit” basis, Shpigler said. Shpigler said a name for the service has not yet been selected.

He is partnering with Consumers Energy and will play an active role in promoting Broadband Over Powerlines in Michigan. Several similar systems are in operation across the country. BPL technology is widely used in Europe.

Shpigler, who is a well-known speaker on telecommunications issues around the country. He first introduced the service last November to the Grand Ledge Area Chamber of Commerce. He said future applications of BPL may include telephones, home security, medical alert, and Web hosting.

FCC Clears Internet Access by Power Lines

FCC Clears Internet Access by Power LinesF.C.C. Clears Internet Access by Power Lines, NY Times, Stephen Labaton

WASHINGTON, Oct. 14 – Clearing the way for homes and businesses to receive high-speed Internet services through their electrical outlets, the Federal Communications Commission adopted rules on Thursday that would enable the utility companies to offer an alternative to the broadband communications services now provided by cable and phone companies.

As a further spur to the roll-out of broadband Internet services, the F.C.C. also ruled that the regional Bell companies do not have to give competitors access to fiber optic lines that reach into consumers’ home – a decision that prompted two of the Bells, SBC Communications and BellSouth, to announce that they would move quickly to build new fiber optic networks in residential neighborhoods. The ruling was criticized by rivals of the Bells and consumer groups, which called it anti-competitive and said it would lead to higher prices.

For the electric companies’ part, broadband Internet service is more than a year away from becoming widely available. But the agency’s ruling is expected to increase significantly the level of investment and interest by the utilities, which had been stymied in previous attempts to offer new services over power lines. Power lines reach more American homes than either telephone lines or television cables.

So far, the technology has been limited mainly to experiments around the country, although a commercial version recently became available in some communities near Cincinnati.

“Today is a banner day, and I think years from now we will look back and see it as a historical day for us,” said Michael K. Powell, the F.C.C.chair. “This is groundbreaking stuff.”

Known as broadband over power lines, or B.P.L., the technology uses a special modem that plugs into electrical outlets. So far, it has been offered at speeds of 1 to 3 megabits a second, which is comparable to broadband service over cable modems or conventional phone lines – though not as fast as the 5 megabits a second achievable through the residential fiber-optic lines just now being introduced by the Bell companies.

An obstacle to the use of power lines to carry communications traffic has been the electromagnetic interference the technology can cause to various types of radio signals. The commission ruled that it would tolerate a small amount of radio interference in certain areas by the new service in exchange for making the broadband market more competitive.

Amateur radio operators and public safety officials had asked the commission to move slowly in the area because of the interference created by the service. The agency responded by setting up a system to monitor interference and restricting the service in areas where it could jeopardize public safety, like areas around airports and near Coast Guard stations.

Officials noted that there have already been field tests in 18 states of the B.P.L. technology. One company, Current Communications, has recently begun to offer broadband service near Cincinnati in a joint venture with Cinergy, the Midwest power and energy company. The service is priced at $29.95 to $49.95 a month, depending on the speed.

While some regulatory and technical issues remain, the technology offers enormous promise because the power grid is ubiquitous. The costs to the industry to offer the new service would be comparatively small, and the possible returns on those investments could be high. If the utility companies do begin to offer the broadband service more widely, they would also be likely to enter the telephone business by offering phone services over the Internet, just as phone and cable companies have begun to do.

Mr. Powell, the F.C.C. chair, said that the new technology would not only offer greater competition in the broadband market but would also allow consumers to easily create networks in their homes through electrical outlets. And adding communications abilities to power lines would permit electric companies to better manage the power grid, he said.

Mr. Powell and three other commissioners voted to approve the rules. The fifth commissioner, Michael J. Copps, dissented in part. He noted that the agency had pushed aside a number of vital issues for another day, including questions of whether utility companies would have to contribute to the telephone industry’s universal service fund and provide access to people with disabilities, and whether measures would be put in place to ensure market competition.

He also said that regulators would need to determine whether it would be fair for electricity customers to pay higher bills “to subsidize an electric company’s foray into broadband.”

“We just have to get to the big picture and confront the challenges I have mentioned if B.P.L. is going to have a shot at realizing its full potential,” Mr. Copps said.

But industry executives praised the decision.

“This is one of the defining moments for the widespread adoption of broadband by Americans,” said William Berkman, chairman of Current Communications, a private company in Germantown, MD, which hopes to have in place a B.P.L. Internet network passing by 50,000 homes by the end of the year. The future also grew brighter for the regional Bell companies with the F.C.C.’s decision to grant BellSouth’s request to exempt the Bells from any requirement that they lease their new fiber lines to the home to rivals at low costs.

Mr. Powell said that the exemption would “restore the marketplace incentives of carriers to invest in new networks.”

Prompted by the decision, the Bells said they would move more rapidly to build fiber networks to homes. So far, the nation’s biggest Bell, Verizon Communications, has been the most active in building residential fiber networks. But on Thursday, SBC said it now planned to provide 18 million households higher speed Internet services in two to three years, rather than five years as previously announced.

“The shovel is in the ground, and we are ready to go,” said SBC’s chairman and chief executive, Edward E. Whitacre Jr.

But rivals, consumer groups, and Mr. Copps criticized the decision as anti-competitive.

The F.C.C. majority seems unable to restrain its preference for monopoly over America’s consumers, business users, and investment, said Len Cali, a vice president for AT&T.

Mark Cooper, director of research at the Consumer Federation of America, said the decision would tighten the already powerful grip that the telephone and cable companies have on broadband services.

“This stranglehold will stifle innovation as these duopolies discriminate against unaffiliated applications and services that in the past have driven the growth of the Internet and the boom in information technology,” Mr.Cooper said.
