November 24, 2020 — In a virtual conversation sponsored by Connected Nation Michigan, Wes Kerr, director of community solutions at Connected Nation, was joined by Chip Spann, director of engineering and technical services at Connected Nation, to discuss the predominant technologies providing broadband service today and detail what kinds of technologies can be expected in the future.

According to Spann, there has been much effort focused on revitalizing the broadband technologies of the past to meet the bandwidth demands of the present moment.

“Vectored DSL technology is keeping many companies in the game,” said Spann, explaining that “vectoring” is a method of increasing the speeds possible over existing digital subscriber lines, so that they can deliver higher bandwidth speeds than they previously would be able to achieve.

The technology is allowing companies like AT&T, CenturyLink, and Frontier to maintain relevancy across their rural DSL networks, rather than retiring the aging copper systems.

VDSL is claimed to be capable of delivering speeds of 80 Megabits per second (Mbps) within the first 500 feet from the DSL Access Multiplexer, and speeds of 10 Mbps at distances up to three to four miles away from the DSLAM, or the DSL Access Multiplexer.

“Many rural Americans currently have no choice besides DSL,” said Spann. “I’m glad to see these companies are stepping up to provide better through-put speeds to those customers.”

Spann detailed the fiber technologies being employed to power futureproof networks across the country and the differences between fiber-to-the-home technologies being utilized.

“The key difference between active optical fiber networks and passive optical fiber networks is how the signal is split between the multiple fibers going to each customer and the resulting speeds,” said Spann.

Active optical fiber networks are considered point-to-point networks, as each customer gets its own individual fiber strand. On the other hand, passive optical fiber networks use optical splitters to divide bandwidth. PON customers share bandwidth, while active ethernet subscribers do not, resulting in a difference in speeds.

While PONs typically offer symmetrical speeds of 1 Gigabit per second, active ethernet can exceed this, commonly offering symmetrical speeds of up to 10 Gbps.

“PONs are advantageous in rural marketplaces because they are more cost effective to deploy,” said Spann, adding that AONs are more beneficial in urban markets.

“XGS-PON, a higher bandwidth symmetrical version of PON, is something you’re going to start hearing about,” said Spann, detailing more future forward technology. XGS-PON is a way of introducing higher bandwidth to PON networks, offering symmetrical speeds of 10 Gbps.

“AT&T has advanced its fiber-to-the-home ‘last mile’ U-Verse network by deploying XGS-PON and has targeted 40 markets across the U.S.,” said Spann.

Looking forward, Spann said 5G and low earth orbit satellites hold the potential to offer new possibilities.

“LEOs claim they can solve the connectivity and latency issues associated with traditional geostationary satellites,” he said. LEO satellites “offer a new opportunity for areas unserved by other broadband technologies, if they work out the way Elon Musk and Jeff Bezos say they will.”

British Telecoms Are Aligning with Emerging U.S. Position on Open RAN Adoption

Open RAN adoption is said to save telecoms money and boost security, as providers are forced to move off Huawei.

Howard Watson, chief technology officer of BT Group

October 18, 2021 – Howard Watson, chief technology officer of telecommunications company BT Group, spoke on Wednesday at the Broadband World Forum about the future of the UK’s network infrastructure, including removing Huawei’s equipment from their networks and developing open radio access networks for wider use.

Speaking at the opening session titled “Building an innovative converged network infrastructure for the UK,” Watson discussed the challenges and possibilities for offering fast, secure broadband and offered O-RAN as a solution for wider connectivity.

Watson discussed utilizing open RAN to facilitate greater interoperability between vendors’ equipment, as it opens the market to more technologies due to its open configuration. The concept advocates for a more open radio access network than provided today, which is held by fewer vendors.

The Federal Communications Commission has pushed for ways to develop open RAN to minimize network security risk, as the movement has gained significant momentum since Huawei was banned over the past 18 months. FCC Acting Commissioner Jessica Rosenworcel has described open RAN as having “extraordinary potential for our economy and national security.”

“When customers go back into the office, the infrastructure they left behind must have key growth” Watson said, referencing the shift in office culture toward remote work during the COVID-19 pandemic.

“Expectations of customers change,” Watson said, adding that “they expect broadband to be always on, they expect high bandwidth.” Above all, “they expect investment no matter the cost.”

BT is seeking to deploy to 90 percent coverage in the UK by 2028.

On the sidelines of his keynote address, Watson noted BT’s progress in limiting Huawei products to 35 percent of an operator’s fiber access footprint by 2023. The UK government requires that Huawei’s equipment must be removed entirely by the end of 2027. The UK considers Huawei a “high risk” vendor for its network infrastructure.

However, BT is waiting for Huawei’s equipment to grow old before replacing it, Watson said. “Our intention is to ensure that we get the full economic life out of the Huawei [products] that we have deployed,” he said. He said BT believes the products can be used until 2031 or later.

“We’re in talks with government about that timeline” Watson said.

Panel discussion about European fiber investment

Watson said that “densification” happens in areas that are fiber rich, so “providing fiber to smaller cell sites is naturally an evolution.”

He said that BT is looking at a range of alternatives including Wi-Fi solutions to getting 1 Gigabit per second (Gbps) capability to household through open architecture-based solutions.

In addition to Watson, a panel focused on the investment parameters for fiber investment featuring officials from Macquarie Group and Eurofiber.

The panel focused on investment challenges and strategies for broadband infrastructure investment and  discussed an opportunistic vision for broadband deployment. Speaking of more mature market with a history of broadband adoption, Macquarie Managing Director Oliver Bradley asked how providers could transition to more efficiency and maximizing the value of an existing network.

Among the principal drivers for investment include co-investing and deregulation, he said.

UTOPIA Fiber Goes to Court in Utah Over American Fork’s Build Permit Refusals

Fiber builder says it has been denied permits that have harmed it and its customers, despite an existing city agreement.

October 13, 2021 – UTOPIA Fiber filed a lawsuit Wednesday against the city of American Fork in Utah for breach of contract after the city allegedly denied build permits to the fiber builder despite there being an existing contract between the two parties.

The fiber provider, which runs an open network on which private telecoms rent space on to provide services, alleges the city had approved some permits that only allowed it to construct backbone transport lines through the city connecting other cities, but denied it key permits that would have allowed it to extend services to UTOPIA Fiber customers inside the city. Those services include connections to American Fork’s public schools.

In July 2020, the city allegedly terminated the 2018 rights-of-way agreement with no explanation, the lawsuit claims. It also alleges that the city specifically discriminated against UTOPIA Fiber by adding additional scrutiny to its permit requests when it believed no such scrutiny existed for other providers.

Broadband Breakfast attempted to make contact with the city, but a phone call was not answered and a voicemail message was not returned by the time of publication.

“American Fork’s refusal to approve permit requests by or for UTOPIA for service laterals for customers within American Fork has harmed UTOPIA, its customers, and the private ISPs who wish to offer services within American Fork using UTOPIA’s Network,” the lawsuit said. “In some cases, UTOPIA has been forced to buy capacity from other network providers that are allowed to install infrastructure in American Fork, so that UTOPIA can fulfill existing contracts with its customers.

“In other cases, UTOPIA has been forced to cancel existing customer orders for connections within American Fork and has lost significant revenues as a result,” the suit added. “UTOPIA has also recently been forced to cancel or reject over a dozen additional customer orders because UTOPIA is unable, due to American Fork’s conduct, to obtain the permits needed to fulfill those orders, and again lost significant revenues as a result.”

In a press release, UTOPIA’s executive director Roger Timmerman said the lawsuit was a “last resort and not an easy decision to make.

“It is our hope that with judicial review, American Fork City will reverse its policies, work within the boundaries of the law, and ultimately, act in the best interest of the people and businesses in American Fork City by allowing them access to the increased options UTOPIA Fiber provides,” Timmerman added.

UTOPIA Fiber is asking the U.S. District Court for the District of Utah to force the city to pay the company damages sustained as a result of the alleged actions, to find the city violated the law with respect to its actions, and to force the city to cease the alleged “discriminatory and preferential actions” against the company.

UTOPIA Fiber, a sponsor of Broadband Breakfast, has designed, built, and operated more than $330 million worth of fiber projects in the state since 2009.

WASHINGTON, October 6, 2021 – Comcast’s business division announced a two-year, $28-million investment to expand fiber through the beltway region of Delaware, Maryland, Virginia, Washington D.C., and West Virginia.

The company said in a press release Wednesday that $13 million of that was invested last year and $15 million have gone into projects that are underway or planned for this year. It is expected to connect nearly 7,000 additional businesses to speeds of up to 100 Gigabits per second for large businesses, it said, adding it’s all part of the $110 million Comcast Business has spent in the area since 2015.

The expansion is part of a larger effort by telecommunications companies in this country to drive fiber to the premises, and to get ahead of the next generation 5G networks. As this is happening, more federal and state dollars are being plowed into broadband infrastructure as President Joe Biden sets his sights on providing access to high-speed internet to 100 percent of the country by the end of the decade.

“The ability to offer both diversity of network and carrier is becoming increasingly important to help drive economic development and transformation,” Ed Rowan, senior director of Comcast Business sales operations in the region, said in the release.

“Connectivity is at the core of this and, more than ever, is an integral factor as businesses expand and prepare for what’s next. Our network expansions across Comcast’s Beltway Region are the latest example of the significant technology investments we’ve made to increase the availability of our multi-Gigabit Ethernet services,” he added. “These investments will help foster economic development, transform our local communities, and better meet next-generation capacity needs across the region.”
